Welcome to Edition 7.44 of the Rocket Report! We had some interesting news on Thursday afternoon from Down Under. As Gilmour Space was preparing for the second launch attempt of its Eris vehicle, as part of the pre-launch preparations, something triggered the payload fairing to deploy. We would love to see some video of that. Please.

Rotating detonation rocket engine takes flight. On Wednesday, US-based propulsion company Venus Aerospace completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico, Ars reports. It is believed to be the first US-based flight test of an idea that has been discussed academically for decades. The concept has previously been tested in a handful of other countries, but never with a high-thrust engine.

Hypersonics on the horizon… The company has only released limited information about the test. The small rocket, powered by the company’s 2,000-pound-thrust engine, launched from a rail in New Mexico. The vehicle flew for about half a minute and, as planned, did not break the sound barrier. Governments around the world have been interested in rotating detonation engine technology for a long time because it has the potential to significantly increase fuel efficiency in a variety of applications, from Navy carriers to rocket engines. In the near term, Venus’ engine could be used for hypersonic missions.

Gilmour Space has a payload fairing mishap. Gilmour Space, a venture-backed startup based in Australia, said this week it was ready to launch a small rocket from its privately owned spaceport on a remote stretch of the country’s northeastern coastline, Ars reports. Gilmour’s three-stage rocket, named Eris, was prepped for a launch as early as Wednesday, but a ground systems issue delayed an attempt until Thursday US time. And then on Thursday, something odd happened: “Last night, during final checks, an unexpected issue triggered the rocket’s payload fairing,” the company said Thursday afternoon, US time.

Always more problems to solve… Gilmour, based in Gold Coast, Australia, was founded in 2012 by two brothers, Adam and James Gilmour, who came to the space industry after careers in banking and marketing. Today, Gilmour employs more than 200 people, mostly engineers and technicians. The debut launch of Gilmour’s Eris rocket is purely a test flight. Gilmour has tested the rocket’s engines and rehearsed the countdown last year, loading propellant and getting within 10 seconds of launch. But Gilmour cautioned in a post on LinkedIn early Wednesday that “test launches are complex.” And it confirmed that on Thursday. Now the company will need to source a replacement fairing, which will probably take a while.

Is an orbital launch from Argentina imminent? We don’t know much about the Argentinian launch company TLON Space, which is developing a (very) small-lift orbital rocket called Aventura 1. According to the company’s website, this launch vehicle will be capable of lofting 25 kg to low-Earth orbit. Some sort of flight test took place two years ago, but the video cuts off after a minute, suggesting that the end of the flight was less than nominal.

Maybe, maybe not… Now, a publication called Urgente24 reports that an orbital launch attempt is underway. It is not clear exactly what this means, and details about what is actually happening at the Malacara Spaceport in Argentina are unclear. I could find no other outlets reporting on an imminent launch attempt. So my guess is that nothing will happen soon, but it is something we’ll keep an eye on regardless. (Submitted by fedeng.)

Poland launches suborbital rocket. Poland has successfully launched a single-stage rocket demonstrator at the Central Air Force Training Ground in Ustka, European Spaceflight reports. The flight was part of a project to develop a three-stage solid-fuel rocket for research payloads. In 2020, the Polish government selected Wojskowe Zakłady Lotnicze No. 1 to lead a consortium developing a three-stage suborbital launch system.

Military uses eyed… The Trójstopniowa Rakieta Suborbitalna (TRS) project involves the Military Institute of Armament Technology and Zakład Produkcji Specjalnej Gamrat and is co-financed by the National Center for Research and Development. The goal of the TRS project is to develop a three-stage rocket capable of carrying a 40-kilogram payload to an altitude exceeding 100 kilometres. While the rocket will initially be used to carry research payloads into space, Poland’s Military Institute of Armament Technology has stated that the technology could also be used for the development of anti-aircraft and tactical missiles.

Latitude signs MoU to launch microsats. On Wednesday, the French launch firm Latitude announced the signing of a memorandum of understanding for the launch of a microsatellite constellation dedicated to storing and processing data directly in orbit. In an emailed news release, Latitude said the “strategic partnership” represents a major step forward in strengthening collaborations between UAE and French space companies.

That’s a lot of launches… Madari Space is developing a constellation of microsatellites (50 to 100 kg), designed as true orbital data centers. Their mission is to store and process data generated on Earth or by other satellites. Latitude plans its first commercial launch with its small-lift Zephyr rocket as early as 2026, with the ambition of reaching a rate of 50 launches per year from 2030. An MoU represents an agreement but not a firm launch contract.

China begins launching AI constellation. China launched 12 satellites early Wednesday for an on-orbit computing project led by startup ADA Space and Zhejiang Lab, Space News reports. A Long March 2D rocket lifted off at 12: 12 am Eastern on Wednesday from Jiuquan Satellite Launch Center in northwest China. Commercial company ADA Space released further details, stating that the 12 satellites form the “Three-Body Computing Constellation,” which will directly process data in space rather than on the ground, reducing reliance on ground-based computing infrastructure.

Putting the intelligence in space… ADA Space claims the 12 satellites represent the world’s first dedicated orbital computing constellation. This marks a shift from satellites focused solely on sensing or communication to ones that also serve as data processors and AI platforms. The constellation is part of a wider “Star-Compute Program,” a collaboration between ADA Space and Zhejiang Lab, which aims to build a huge on-orbit network of 2,800 satellites.

SpaceX pushes booster reuse record further. SpaceX succeeded with launching 28 more Starlink satellites from Florida early Tuesday morning following an overnight scrub the previous night. The Falcon 9 booster, 1067, made a record-breaking 28th flight, Spaceflight Now reports.

Booster landings have truly become routine… A little more than eight minutes after liftoff, SpaceX landed B1067 on its drone ship, Just Read the Instructions, which was positioned in the Atlantic Ocean to the east of the Bahamas. This marked the 120th successful landing for this drone ship and the 446th booster landing to date for SpaceX. (Submitted by EllPeaTea.)

What happens if Congress actually cancels the SLS rocket? The White House Office of Management and Budget dropped its “skinny” budget proposal for the federal government earlier this month, and the headline news for the US space program was the cancellation of three major programs: the Space Launch System rocket, the Orion spacecraft, and the Lunar Gateway. In a report, Ars answers the question of what happens to Artemis and NASA’s deep space exploration plans if that happens. The most likely answer is that NASA turns to an old but successful playbook: COTS.

A market price for the Moon… This stands for Commercial Orbital Transportation System and was created by NASA two decades ago to develop cargo transport systems (eventually, this became SpaceX’s Dragon and Northrop’s Cygnus spacecraft) for the International Space Station. Since then, NASA has adopted this same model for crew services as well as other commercial programs. Under the COTS model, NASA provides funding and guidance to private companies to develop their own spacecraft, rockets, and services and then buys those at a “market” rate. Sources indicate that NASA would go to industry and seek an “end-to-end” solution for lunar missions—that is, an integrated plan to launch astronauts from Earth, land them on the Moon, and return them to Earth.

Starship nearing its next test flight. SpaceX fired six Raptor engines on the company’s next Starship rocket Monday, clearing a major hurdle on the path to launch later this month on a high-stakes test flight to get the private rocket program back on track. SpaceX hasn’t officially announced a target launch date, but sources indicate a launch could take place toward the end of next week, prior to Memorial Day weekend, Ars reports. The launch window would open at 6: 30 pm local time (7: 30 pm EDT; 23: 30 UTC).

Getting back on track… If everything goes according to plan, Starship is expected to soar into space and fly halfway around the world, targeting a reentry and controlled splashdown into the Indian Ocean. While reusing the first stage is a noteworthy milestone, the next flight is important for another reason. SpaceX’s last two Starship test flights ended prematurely when the rocket’s upper stage lost power and spun out of control, dropping debris into the sea near the Bahamas and the Turks and Caicos Islands.

Next three launches

Rocket Report: Rocket Lab to demo cargo delivery; America’s new ICBM in trouble


SpaceX’s plan to turn Starbase into Texas’ newest city won the approval of voters—err, employees.

Welcome to Edition 7.43 of the Rocket Report! There’s been a lot of recent news in hypersonic testing. We cover some of that in this week’s newsletter, which is just a taste of the US military’s appetite for fielding its own hypersonic weapons, and conversely, the Pentagon’s emphasis on the detection and destruction of an enemy’s hypersonic missiles. China has already declared its first hypersonic weapons operational, and Russia claims to have them, too. Now, the Pentagon is finally close to placing hypersonic missiles with combat units. Many US rocket companies believe the hypersonics sector is a lucrative business. Some companies have enough confidence in this emerging market—or lack of faith in the traditional space launch market—to pivot entirely toward hypersonics. I’m interested in seeing if their bets pay off.

Stratolaunch tests reusable hypersonic rocket plane. Stratolaunch has finally found a use for the world’s largest airplane. Twice in the last five months, the company launched a hypersonic vehicle over the Pacific Ocean, accelerated it to more than five times the speed of sound, and autonomously landed at Vandenberg Space Force Base in California, Ars reports. Stratolaunch used the same Talon-A vehicle for both flights, demonstrating its reusability, a characteristic that sets it apart from competitors. Zachary Krevor, Stratolaunch’s president and CEO, said his team aims to ramp up to monthly flights by the end of the year.

A 21st century X-15 … This is the first time anyone in the United States has flown a reusable hypersonic rocket plane since the last flight of the X-15, the iconic rocket-powered aircraft that pushed the envelope of high-altitude, high-speed flight 60 years ago. Like the Talon-A, the X-15 released from a carrier jet and ignited a rocket engine to soar into the uppermost layers of the atmosphere. But the X-15 had a pilot in command, while the Talon-A flies on autopilot. Stratolaunch is one of several companies participating in a US military program to test parts and technologies for use on future hypersonic weapons. “Why the autonomous flight matters is because hypersonic systems are now pushing the envelope in terms of maneuvering capability, maneuvering beyond what can be done by the human body,” Krevor said.

New details about another recent hypersonic test. A hypersonic missile test on April 25 validated the launch mechanism for the US Navy Conventional Prompt Strike (CPS) weapon program, the Defense Department said on May 2. The CPS missile, the Navy’s name for what the US Army calls the Long Range Hypersonic Weapon (LRHW), launched from Cape Canaveral Space Force Station, Florida, Aviation Week & Space Technology reports. While the Army and Navy versions use the same hypersonic glide vehicle and missile, they use different launch mechanisms. Last year, the Army tested its version of the hypersonic missile launcher. Now, the Navy has validated the cold-gas launch mechanism it will install on guided missile destroyers.

Deploying soon … “The cold-gas approach allows the Navy to eject the missile from the platform and achieve a safe distance above the ship prior to first stage ignition,” said Vice Adm Johnny R. Wolfe Jr., director of the Navy’s Strategic Systems Programs, which is the lead designer of the common hypersonic missile. The Army plans to field its Long Range Hypersonic Weaponalso called “Dark Eagle”with a combat unit later this year, while the Navy’s version won’t be ready for testing at sea until 2027 or 2028. Both missiles are designed for conventional (non-nuclear) strikes. The Army’s Dark Eagle will be the US military’s first operational hypersonic weapon.

Sentinel needs new silos. The Air Force will have to dig entirely new nuclear missile silos for the LGM-35A Sentinel, creating another complication for a troubled program that is already facing future cost and schedule overruns, Defense News reports. The Air Force originally hoped the existing silos that have housed Minuteman III intercontinental ballistic missiles could be adapted to launch Sentinel missiles, which would be more efficient than digging entirely new silos. But a test project at Vandenberg Space Force Base in California showed that approach would be fraught with further problems and cause the program to run even further behind and over budget, the service said.

Rising costs … Sentinel, developed by Northrop Grumman, will replace the Air Force’s fleet of Minuteman III ICBMs, which entered service in 1970, as the land-based leg of the military’s nuclear triad. Sentinel was originally expected to cost $77.7 billion, but projected future costs ran so severely over budget that in January 2024, the program triggered a review process known as a critical Nunn-McCurdy breach. After that review, the Pentagon last year concluded Sentinel was too critical to national security to abandon, but ordered the Air Force to restructure it to bring its costs under control. Additional studies of the program are highlighting more potential problems.

Gilmour says it (hopefully) will wait no more. The Australian launch startup Gilmour Space Technologies has been given approval by Australia’s Civil Aviation Safety Authority for the debut launch of its Eris orbital rocket, InnovationAus.com reports. There is still one final regulatory hurdle, a final sign-off from the Australian Space Agency. If that happens in the next few days, Gilmour’s launch window will open May 15. The company has announced tentative launch schedules before, only to be thwarted by technical issues, regulatory hangups, or bad weather. Most recently, Gilmour got within six days of its targeted launch date in March before regulatory queries and the impact of a tropical cyclone forced a delay.

Stand by for history … The launch of Gilmour’s three-stage Eris rocket will be historic. If successful, the 82-foot-tall (25-meter) rocket will be Australia’s first homegrown orbital launcher. Eris is capable of hauling cargos up to 672 pounds (305 kilograms) to orbit, according to Gilmour. The company has dispatched a small team from its Gold Coast headquarters to the launch site in Queensland, on Australia’s northeastern coast, to perform testing on the vehicle after it remained dormant for weeks.

Fresh insights into one of SpaceX’s worst days. When a Falcon 9 rocket exploded on its launch pad nearly nine years ago, SpaceX officials initially struggled to explain how it could have happened. The lack of a concrete explanation for the failure led SpaceX engineers to pursue hundreds of theories. One was the possibility that an outside “sniper” had shot the rocket. This theory appealed to SpaceX founder Elon Musk. A building leased by SpaceX’s main competitor in launch, United Launch Alliance, lay just a mile away from the Falcon 9 launch pad, and a video around the time of the explosion indicated a flash on its roof. Ars has now obtained a letter sent to SpaceX by the Federal Aviation Administration more than a month after the explosion, indicating the matter was elevated to the FBI. The bureau looked into it, and what did they find? Nothing, apparently.

Investigation terminated … “The FBI has informed us that based upon a thorough and coordinated review by the appropriate Federal criminal and security investigative authorities, there were no indications to suggest that sabotage or any other criminal activity played a role in the September 1 Falcon 9 explosion,” an FAA official wrote in the letter to SpaceX. Ultimately, engineers determined the explosion was caused by the sudden failure of a high-pressure helium tank on the Falcon 9’s upper stage.

Eric Schmidt’s motivations become clearer. In the nearly two months since former Google chief executive Eric Schmidt acquired Relativity Space, the billionaire has not said much publicly about his plans for the launch company. However, his intentions for Relativity are becoming increasingly clear: He wants to have the capability to launch a significant amount of computing infrastructure into space, Ars reports. During a congressional hearing last month, Schmidt discussed the need more electricity to power data centers that will facilitate the computing needs for AI development and applications.

How big this crisis is … “People are planning 10 gigawatt data centers,” Schmidt said at the hearing. “Gives you a sense of how big this crisis is.” In an exchange with my colleague Eric Berger on X, Schmidt seemed to confirm he bought Relativity Space as a means to support the development of data centers in space. Such data centers, ideally, would be powered by solar panels and be able to radiate heat into the vacuum of space. Relativity’s Terran R rocket, still in development, is well-sized to play a role in launching the infrastructure for data centers in space. But several big questions remain: How big would these data centers be? Where would they go within an increasingly cluttered low-Earth orbit? Could space-based solar power meet their energy needs? Can all of this heat be radiated away efficiently in space? Economically, would any of this make sense?

Rocket Lab, meet Rocket Cargo. Rocket Lab’s next-generation Neutron rocket has been selected for an experimental US Air Force mission to test rapid, global, cargo-delivery capabilities, a milestone for the company as it pushes further into the national security launch market, Space News reports. The mission, slated for no earlier than 2026, will fall under the Air Force Research Laboratory’s (AFRL) “Rocket Cargo” program, which explores how commercial launch vehicles might one day deliver materiel to any point on Earth within hours—a vision akin to airlift logistics via spaceflight.

A new mission for Neutron … Peter Beck, Rocket Lab’s founder and CEO, said the Rocket Cargo contract from AFRL represents an “experimental phase” of the program. “It’ll be interesting to see if that turns into a full requirement for an operational capability,” he said Thursday. Neutron is expected to carry a payload that will reenter Earth’s atmosphere, demonstrating the rocket’s ability to safely transport and deploy cargo. SpaceX’s Starship, with roughly 10 times more payload lift capacity than Neutron, is also on contract with AFRL for demonstrations for the Rocket Cargo program. Meanwhile, Beck said Neutron remains on schedule for its inaugural launch from Wallops Island, Virginia, later this year.

Trump calls for canceling the Space Launch System. The Trump administration released its “skinny” budget proposal earlier this week. Overall, NASA is asked to take a 25 percent cut in its budget, from about $25 billion to $18.8 billion. There are also significant changes proposed in NASA’s biggest-ticket exploration programs. The budget would cancel the Lunar Gateway that NASA has started developing and end the Space Launch System rocket and Orion spacecraft after two more flights, Artemis II and Artemis III, Ars reports. A statement from the White House calls the SLS rocket “grossly expensive” with projected costs of $4 billion per launch.

If not SLS, then what? … “The budget funds a program to replace SLS and Orion flights to the Moon with more cost-effective commercial systems that would support more ambitious subsequent lunar missions,” the Trump administration wrote. There are no further details about those commercial systems. NASA has contracted with SpaceX and Blue Origin to develop reusable landers for the Moon, and both of these systems include vehicles to move from Earth orbit to the Moon. In the budget proposal, the White House sets a priority for a human expedition to Mars to follow the Artemis program’s lunar landing.

FAA unlocks SpaceX launch cadence. Although we are still waiting for SpaceX to signal when it will fly the Starship rocket again, the company got some good news from the Federal Aviation Administration on Tuesday, Ars reports. After a lengthy review, the federal agency agreed to allow SpaceX to substantially increase the number of annual launches from its Starbase launch site in South Texas. Previously, the company was limited to five launches, but now it will be able to conduct up to 25 Starship launches and landings during a calendar year.

Waiting for clearance … Although the new finding permits SpaceX to significantly increase its flight rate from South Texas, the company still has work to do before it can fly Starship again. The company’s engineers are still working to get the massive rocket back to flight after its eighth mission broke apart off the coast of Florida on March 6. This was the second time, in two consecutive missions, that the Starship upper stage failed during its initial phase of flight. After two consecutive failures, there will be a lot riding on the next test flight of Starship. It will also be the first time the company attempts to fly a first stage of the rocket for a second time. According to some sources, if additional testing of this upper stage goes well, Starship could launch as early as May 19. This date is also supported by a notice to mariners, but it should be taken as notional rather than something to be confident in.

SpaceX adds to its dominion. Elon Musk’s wish to create his own city has come true, the Texas Tribune reports. On Saturday, voters living around SpaceX’s Starship rocket testing and launch facility in South Texas approved a measure to incorporate the area as a new city. Unofficial results later Saturday night showed the election was a landslide: 212 voted in favor; 6 opposed. After the county certifies the results, the new city will be official.

Elections have consequences … Only 283 people, those who live within the boundaries of the proposed city, were eligible to vote in the election. A Texas Newsroom analysis of the voter rolls showed two-thirds of them either work for SpaceX or had already indicated their support. The three unopposed people who ran to lead the city also have ties to SpaceX. It’s not clear if Musk, whose primary residence is at Starbase, cast a ballot. The vote clears the way for Musk to try to capture more control over the nearby public beach, which must be closed for launches.

Welcome to Edition 7.41 of the Rocket Report! NASA and its contractors at Kennedy Space Center in Florida continue building a new mobile launch tower for the Space Launch System Block 1B rocket, a taller, upgraded version of the SLS rocket being used for the agency’s initial Artemis lunar missions. Workers stacked another segment of the tower a couple of weeks ago, and the structure is inching closer to its full height of 355 feet (108 meters). But this is just the start. Once the tower is fully assembled, it must be outfitted with miles of cabling, tubing, and piping and then be tested before it can support an SLS launch campaign. Last year, NASA’s inspector general projected the tower won’t be ready for a launch until the spring of 2029, and its costs could reach $2.7 billion. The good news, if you can call it that, is that there probably won’t be an SLS Block 1B rocket that needs to use it in 2029, whether it’s due to delays or cancellation.

Fresh details on Astra’s strategic pivot. Astra, the once high-flying rocket startup that crashed back to Earth with investors before going private last year, has unveiled new details about its $44 million contract with the Department of Defense, Space News reports. The DOD contract announced last year supports the development of Rocket 4, a two-stage, mobile launch vehicle with ambitions to deliver cargo across the globe in under an hour. While Astra’s ill-fated Rocket 3 focused on launching small satellites into low-Earth orbit, Astra wants to make Rocket 4 a military utility vehicle. Rocket 4 will still be able to loft conventional satellites, but Astra’s most lucrative contract for the new launch vehicle involves using the rocket for precise point-to-point delivery of up to 1,300 pounds (590 kilograms) of supplies from orbit via specialized reentry vehicles. The military has shown interest in developing a rocket-based rapid global cargo delivery system for several years, and it has a contract with SpaceX to study how the much larger Starship rocket could do a similar job.

Back from the brink… The Alameda, California-based company, which was delisted from Nasdaq in June 2024 after its shares collapsed, is now targeting the first test flight of Rocket 4 in 2026. Astra’s arrangement with the Defense Innovation Unit includes two milestones: one suborbital (point-to-point) and the other orbital, with the option to launch from a location outside the United States, as Astra is developing a mobile launcher. Chris Kemp, Astra’s co-founder and CEO, told Space News the orbital launch will likely originate from Australia. Astra’s first launches with the new-retired Rocket 3 vehicle were based in Alaska and Florida.

The Army has a catchy name for its newest weapon. The Long Range Hypersonic Weapon has a new name: Dark Eagle. The US Army announced the popular name for the service’s quick strike missile this week. “Part of the name pays tribute to the eagle—a master hunter known for its speed, stealth and agility—due to the LRHW’s combination of velocity, accuracy, maneuverability, survivability and versatility,” the Army said in a press release. “In addition, the bald eagle—our national bird—represents independence, strength, and freedom.” The Dark Eagle is designed to strike targets with little or no warning via a hypersonic glide vehicle capable of maneuvering in the upper atmosphere after an initial launch with a conventional missile. The hypersonic weapon’s ability to overcome an adversary’s air and missile defenses is embodied in the word “dark” in Dark Eagle, the Army said.

Flying again soon… The Army tested the hypersonic weapon’s “all-up round” during a missile launch from Cape Canaveral, Florida, in December. The test was delayed more than a year due to unspecified issues. The Army appears to be preparing for another Dark Eagle test from Florida’s Space Coast as soon as Friday, according to airspace and maritime warning notices in the Atlantic Ocean.

Northrop’s niche with Minotaur. Ars mentioned in last week’s Rocket Report that Northrop Grumman’s Minotaur IV rocket launched April 16 with a classified payload for the National Reconnaissance Office. This was the first Minotaur IV launch in nearly five years and the first orbital Minotaur launch from Vandenberg Space Force Base, California, in 14 years. The low-volume Minotaur IV uses solid rocket motors from the Air Force’s stockpile of retired Peacekeeper ballistic missiles, turning part of a weapon of mass destruction into, in this case, a tool to support the US government’s spy satellite agency. The Minotaur IV’s lift capability fits neatly between the capacity of smaller commercial rockets, like Firefly’s Alpha or Rocket Lab’s Electron, and larger rockets like SpaceX’s Falcon 9. The most recent Minotaur IV launch contract cost the Space Force roughly $30 million, more than a mission with Firefly but less than a dedicated ride on a Falcon 9.

Minotaur IV will keep flying… The Space Force has at least two more missions reserved to launch on the expendable Minotaur IV rocket. One of the missions will launch multiple small satellites for the US military’s Space Test Program, and the other will place a military weather satellite into orbit. Both missions will launch from California, with planning launch dates in 2026, a Space Systems Command spokesperson told Ars. “We do have multiple launches planned using Minotaur family launch vehicles between our OSP-4 (Orbital/Suborbital Program) and SRP-4 (Sounding Rocket Program) contracts,” the spokesperson said. “We will release more information on those missions as we get closer to launch.” The Commercial Space Act of 1998 prohibits the use of surplus ICBM motors for commercial launches and limits their use to only specific kinds of military launches. The restrictions were intended to encourage NASA and commercial satellite operators to use privately developed launch vehicles.

NASA’s launch prices have somehow gone up. In an era of reusable rockets and near-daily access to space, NASA is still paying more than it did 30 years ago to launch missions into orbit, according to a study soon to be published in the scientific journal Acta Astronautica. Adjusted for inflation, the prices NASA pays for launch services rose at an annual average rate of 2.82 percent from 1996 to 2024, the report says. “Furthermore, there is no evidence of shift in the launch service costs trend after the introduction of a new launch service provider [SpaceX] in 2016.” Ars analyzed NASA’s launch prices in a story published Thursday.

Why is this? … One might think SpaceX’s reuse of Falcon 9 rocket components would drive down launch prices, but no. Rocket reuse and economies of scale have significantly reduced SpaceX’s launch costs, but the company is charging NASA roughly the same as it did before booster reuse became commonplace. There are a few reasons this is happening. One is that SpaceX hasn’t faced any meaningful competition for NASA launch contracts in the last six years. That should change soon with the recent debuts of United Launch Alliance’s Vulcan rocket and Blue Origin’s New Glenn launcher. NASA levies additional requirements on its commercial launch providers, and the agency must pay for them. These include schedule priority, engineering oversight, and sometimes special payload cleanliness requirements and the choice of a particular Falcon 9 booster from SpaceX’s inventory.

What’s holding up ULA’s next launch? After poor weather forced ULA to scrub a launch attempt on April 9, the company will have to wait nearly three weeks for another try to launch an Atlas V rocket with Amazon’s first full-up load of 27 Kuiper broadband satellites, Ars reports. The rocket and satellites are healthy, according to ULA. But the military-run Eastern Range at Cape Canaveral Space Force Station, Florida, is unable to accommodate ULA until Monday, April 28. The Space Force is being unusually cagey about the reasons for the lengthy delay, which isn’t affecting SpaceX launches to the same degree.

Finally, a theory… The publishing of airspace and maritime warning notices for an apparent test launch of the Army’s Long Range Hypersonic Weapon, or Dark Eagle, might explain the range’s unavailability. The test launch could happen as soon as Friday, and offshore keep-out zones cover wide swaths of the Atlantic Ocean. If this is the reason for the long Atlas V launch delay, we still have questions. If this launch is scheduled for Friday, why has it kept ULA from launching the last few weeks? Why was SpaceX permitted to launch multiple times in the same time period? And why didn’t the first test flight of the Dark Eagle missile in December result in similar lengthy launch delays on the Eastern Range?

Shenzhou 20 bound for Tiangong. A spaceship carrying three astronauts docked Thursday with China’s space station in the latest crew rotation, approximately six hours after their launch on a Long March 2F rocket from the Gobi Desert, the Associated Press reports. The Shenzhou 20 mission is commanded by Chen Dong, who is making his third flight. He is accompanied by fighter pilot Chen Zhongrui and engineer Wang Jie, both making their maiden voyages. They will replace three astronauts currently on the Chinese Tiangong space station. Like those before them, they will stay on board for roughly six months.

Finding a rhythm… China’s human spaceflight missions have launched like clockwork since the country’s first domestic astronaut launch in 2003. Now, with the Tiangong space station fully operational, China is launching fresh crews at six-month intervals. While in space, the astronauts will conduct experiments in medical science and new technologies and perform spacewalks to carry out maintenance and install new equipment. Their tasks will include adding space debris shielding to the exterior of the Tiangong station. (submitted by EllPeaTea)

SpaceX resupplies the ISS. SpaceX launched an uncrewed Cargo Dragon spacecraft to the International Space Station early Monday on a resupply mission with increased importance after a transportation mishap derailed a flight by another US cargo ship, Spaceflight Now reports. The Dragon cargo vessel docked at the space station early Tuesday with 4,780 pounds (2,168 kilograms) of pressurized cargo and 1,653 pounds (750 kilograms) of unpressurized payloads in the vehicle’s trunk. NASA adjusted the Dragon spacecraft’s payload because an upcoming flight by Northrop Grumman’s Cygnus supply freighter was canceled after the Cygnus cargo module was damaged during transport to the launch site.

Something strange… The payloads aboard this Dragon cargo mission—the 32nd by SpaceX—include normal things like fresh food (exactly 1,262 tortillas), biomedical and pharmaceutical experiments, and the technical demonstration of a new atomic clock. However, there’s something onboard nobody at NASA or SpaceX wants to talk about. A payload package named STP-H10 inside Dragon’s trunk section will be installed on a mounting post outside of the space station to perform a mission for the US military’s Space Test Program. STP-H10 wasn’t mentioned in NASA’s press kit for this mission, and SpaceX didn’t show the usual views of Dragon’s trunk when the spacecraft deployed from its Falcon 9 rocket shortly after launch. These kinds of Space Test Program experiment platforms have launched to the ISS before without any secrecy. Stranger still is the fact that the STP-H10 experiments are unclassified. You can see the list here. (submitted by EllPeaTea)

There are some drawbacks to rideshare. SpaceX launched its third “Bandwagon” rideshare mission into a mid-inclination orbit Monday evening from Cape Canaveral Space Force Station, Space News reports. The payloads included a South Korean military radar spy satellite, a small commercial weather satellite, and the most interesting payload: an experimental reentry vehicle from a German startup named Atmos Space Cargo. The startup’s Phoenix vehicle, fitted with an inflatable heat shield, separated from the Falcon 9’s upper stage about 90 minutes after liftoff. Roughly a half-hour later, it began reentry for a splashdown in the South Atlantic Ocean, about 1,200 miles (2,000 kilometers) off the coast of Brazil. Until last month, the Phoenix vehicle was supposed to reenter over the Indian Ocean east of Madagascar, near the island of Réunion. The late change to the mission’s trajectory meant Atmos could not recover the spacecraft after splashdown.

Changes in longitude… Five weeks before the launch, SpaceX informed Atmos of a change in trajectory because of “operational constraints” of the primary payload, a South Korean reconnaissance satellite. Smaller payloads on rideshare launches benefit from lower launch prices, but their owners have no control over the schedule or trajectory of the launch. The change for this mission resulted in a splashdown well off the coast of Brazil, ruling out any attempt to recover Phoenix after splashdown. It also meant a steeper reentry than previously planned, creating higher loads on the spacecraft. The company lined up new ground stations in South America to communicate with the spacecraft during key phases of flight leading up to reentry. In addition, it chartered a plane to attempt to collect data during reentry, but the splashdown location was beyond the range of the aircraft. Some data suggests that the heat shield inflated as planned, but Atmos’s CEO said the company needed more time to analyze the data it had, adding that it was “very difficult” to get data from Phoenix in the final phases of its flight, given its distance from ground stations.

Ariane 6 is gonna need a bigger booster. A qualification motor for an upgraded solid rocket booster for Europe’s Ariane 6 rocket successfully fired up for the first time on a test stand Thursday in Kourou, French Guiana, according to the European Space Agency. The new P160C solid rocket motor burned for more than two minutes, and ESA declared the test-firing a success. ESA’s member states approved the development of the P160C motor in 2022. The upgraded motor is about 3 feet (1 meter) longer than the P120C motor currently flying on the Ariane 6 rocket and carries about 31,000 pounds (14 metric tons) more solid propellant. The Ariane 6 rocket can fly with two or four of these strap-on boosters. Officials plan to introduce the P160C on Ariane 6 flights next year, giving the rocket’s heaviest version the ability to haul up to 4,400 pounds (2 metric tons) of additional cargo mass to orbit.

A necessary change… The heavier P160C solid rocket motor is required for Arianespace to fulfill its multi-mission launch contract with Amazon’s Project Kuiper satellite broadband network. Alongside similar contracts with ULA and Blue Origin, Amazon reserved 18 Kuiper launches on Ariane 6 rockets, and 16 of them must use the upgraded P160C booster to deliver additional Kuiper satellites to orbit. The P160C is a joint project between ArianeGroup and Avio, which will use the same motor design on Europe’s smaller Vega C rocket to improve its performance. (submitted by EllPeaTea)

Progress toward the second flight of New Glenn. Blue Origin CEO Dave Limp said his team completed a full-duration 15-second hot-fire test Thursday of the upper stage for the company’s second New Glenn rocket. In a post on X, Limp wrote that the upper stage for the next New Glenn flight will have “enhanced performance.” The maximum power of its hydrogen-fueled BE-3U engine will increase from 173,000 pounds to 175,000 pounds of thrust. Two BE-3U engines fly on New Glenn’s second stage.

A good engine… The BE-3U engine is a derivative of the BE-3 engine flying on Blue Origin’s suborbital New Shepard rocket. Limp wrote that the upper stage on the first New Glenn launch in January “performed remarkably” and achieved an orbital injection with less than 1 percent deviation from its target. So when will New Glenn launch again? We’ve heard late spring, June, or October, depending on the source. I’ll note that Blue Origin test-fired the New Glenn upper stage for the rocket’s first flight about four months before it launched.

Welcome to Edition 7.40 of the Rocket Report! One of the biggest spaceflight questions in my mind right now is when Blue Origin’s New Glenn rocket will fly again. The company has been saying “late spring.” Today, the Aerospace Safety Advisory Panel said they were told June. Several officials have suggested to Ars that the next launch will, in reality, occur no earlier than October. So when will we see New Glenn again?

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Phantom Space delays Daytona launch, again. In a story that accepts what Phantom Space Founder Jim Cantrell says at face value, Payload Space reports that the company is “an up-and-coming launch provider and satellite manufacturer” and has “steadily built a three-pronged business model to take on the industry’s powerhouses.” It’s a surprisingly laudatory story for a company that has yet to accomplish much in space.

Putting the brakes on Daytona … What caught my eye is the section on the Daytona rocket, a small-lift vehicle the company is developing. “The company expects to begin flying Daytona late next year or early 2027, and already has a Daytona II and III in the works,” the publication reports. Why is this notable? Because in an article published less than two years ago, Cantrell said Phantom was hoping to launch an orbital test flight in 2024. In other words, the rocket is further from launch today than it was in 2023. I guess we’ll see what happens. (submitted by BH)

It appears the Minotaur IV rocket still exists. A Northrop Grumman Minotaur IV rocket successfully launched multiple classified payloads for the US National Reconnaissance Office on Wednesday, marking a return to Vandenberg Space Force Base for the solid-fueled launch vehicle after more than a decade, Space News reports. The mission, designated NROL-174, lifted off at 3: 33 pm Eastern from Space Launch Complex 8 at Vandenberg, California. The launch was successful.

Back on the California Coast … The Minotaur IV is a four-stage vehicle derived in part from decommissioned Peacekeeper intercontinental ballistic missiles. The first three stages are government-furnished Peacekeeper solid rocket motors, while the upper stage is a commercial Orion solid motor built by Northrop Grumman. NROL-174 follows previous NRO missions flown on Minotaur rockets—NROL-129 in 2020 and NROL-111 in 2021—both launched from NASA’s Wallops Flight Facility in Virginia. (submitted by EllPeaTea)

French launch firm gets some funding runway. The French government has awarded Latitude funding to support the construction of its new rocket factory in Reims, which is expected to open in 2026, European Spaceflight reports. Latitude first announced plans to develop a larger rocket factory in late 2023, when it expanded its original site from 1,500 to 3,000 square meters. The new facility is expected to span approximately 25,000 square meters and will support a production capacity of up to 50 Zephyr rockets per year.

Working toward a launch next year … The Zephyr rocket is designed to deliver payloads of up to 200 kilograms to low-Earth orbit. It could make its debut in 2026 if all goes well. Latitude did not disclose the exact amount of funding it received for the construction of its new factory. However, it is known that while part of the funding will be awarded as a straight grant, a portion will take the form of a recoverable loan. (submitted by EllPeaTea)

RFA gets a new CEO. German launch vehicle startup Rocket Factory Augsburg has replaced its chief executive as it works toward a second chance for its first launch, Space News reports. Last Friday, RFA announced that Stefan Tweraser, who had been chief executive since October 2021, had been replaced by Indulis Kalnins.

Working toward a second launch attempt … The announcement did not give a reason for the change, but it suggested that the company was seeking someone with expertise in the aerospace industry to lead the company. Kalnins is on the aerospace faculty of a German university, Hochschule Bremen, and has been managing director of OHB Cosmos, which focused on launch services. RFA is working toward a second attempt at a first flight for RFA ONE later this year. (submitted by EllPeaTea)

Blue Origin launches all-female mission. Blue Origin’s 11th human flight—and first with an all-female flight team—blasted off from West Texas’ Launch Site One Monday morning on a flight that lasted about 10 minutes, Travel + Leisure reports. Katy Perry and Gayle King were joined by aerospace engineer Aisha Bowe, civil rights activist and scientist Amanda Nguyễn, film producer Kerianne Flynn, and Jeff Bezos’ fiancée, Lauren Sánchez.

I kissed a Kármán line … “This experience has shown me you never know how much love is inside of you, how much love you have to give, and how loved you are, until the day you launch,” Perry said in her post-flight interview on the Blue Origin livestream, calling the experience “second only to being a mom” and rating it “10 out of 10.”

Bahamas to SpaceX: Let’s press pause. The Bahamas government said on Tuesday it is suspending all SpaceX Falcon 9 rocket landings in the country, pending a full post-launch investigation of the latest Starship mishap, Reuters reports. “No further clearances will be granted until a full environmental assessment is reviewed,” Bahamian Director of Communications Latrae Rahming said.

Falling from the sky … The Bahamian government said in February, after SpaceX’s first Falcon 9 first stage landing in the country, that it had approved 19 more throughout 2025, subject to regulatory approval. The Bahamas’ post-launch investigation comes after a SpaceX Starship spacecraft exploded in space last month, minutes after lifting off from Texas. Following the incident, the Bahamas said debris from the spacecraft fell into its airspace.

NASA will fly on Soyuz for a while longer. NASA and Roscosmos have extended a seat barter agreement for flights to the International Space Station into 2027 that will feature longer Soyuz missions to the station, Space News reports. Under the no-exchange-of-funds barter agreement, NASA astronauts fly on Soyuz spacecraft and Roscosmos cosmonauts fly on commercial crew vehicles to ensure that there is at least one American and one Russian on the station should either Soyuz or commercial crew vehicles be grounded for an extended period. “NASA and Roscosmos have amended the integrated crew agreement to allow for a second set of integrated crew missions in 2025, one set of integrated crew missions in 2026, and a SpaceX Dragon flight in 2027,” an agency spokesperson said.

Flying fewer times per year. One change with the agreement is the cadence of Soyuz missions. While Roscosmos had been flying Soyuz missions to the ISS every six months, missions starting with Soyuz MS-27 this April will spend eight months at the station. Neither NASA nor Roscosmos offered a reason for the change, which means that Roscosmos will fly one fewer Soyuz mission over a two-year period: three instead of four. I presume that this is a cost-saving measure. (submitted by EllPeaTea)

Falcon 9 sets reuse record. SpaceX notched another new rocket reuse record with its midnight Starlink flight on Sunday night from Florida, Spaceflight Now reports. The Falcon 9 rocket booster with the tail number 1067 launched for a record-setting 27th time, further cementing its position as the flight leader among SpaceX’s fleet.

Approaching 500 launches … It supported the launch of 27 Starlink V2 Mini satellites heading into low-Earth orbit. The 27th outing for B1067 comes nearly four years after it launched its first mission, CRS-22, on June 3, 2021. Its three most recent missions were all in support of SpaceX’s Starlink satellite constellation. The Starlink 6-73 mission was also the 460th launch of a Falcon 9 rocket to date.

The real story behind the Space Shuttle legislation. Last week, two US senators from Texas, John Cornyn and Ted Cruz, filed the “Bring the Space Shuttle Home Act” to move Space Shuttle Discovery from its current location at the Smithsonian’s National Air and Space Museum’s Steven F. Udvar-Hazy Center in Virginia to Houston. After the senators announced their bill, the collective response from the space community was initially shock. This was soon followed by: why? Ars spoke with several people on background, both from the political and space spheres, to get a sense of what is really happening here.

Bill is not going anywhere … The short answer is that it is all political, and the timing is due to the reelection campaign for Cornyn, who faces a stiff runoff against Ken Paxton. The legislation is, in DC parlance, a “messaging bill.” Cornyn is behind this, and Cruz simply agreed to go along. The goal in Cornyn’s campaign is to use the bill as a way to show Texans that he is fighting for them in Washington, DC, against the evils there. Presumably, he will blame the Obama administration, even though it is quite clear in hindsight that there were no political machinations behind the decision to not award a space shuttle to Houston. Space Center Houston, which would be responsible for hosting the shuttle, was not even told about the legislation before it was filed.

China’s approach to space junk is worrisome as it begins launching its own megaconstellations.

Welcome to Edition 7.39 of the Rocket Report! Not getting your launch fix? Buckle up. We’re on the cusp of a boom in rocket launches as three new megaconstellations have either just begun or will soon begin deploying thousands of satellites to enable broadband connectivity from space. If the megaconstellations come to fruition, this will require more than a thousand launches in the next few years, on top of SpaceX’s blistering Starlink launch cadence. We discuss the topic of megaconstellations in this week’s Rocket Report.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site).

So, what is SpinLaunch doing now? Ars Technica has mentioned SpinLaunch, the company that literally wants to yeet satellites into space, in previous Rocket Report newsletters. This company enjoyed some success in raising money for its so-crazy-it-just-might-work idea of catapulting rockets and satellites into the sky, a concept SpinLaunch calls “kinetic launch.” But SpinLaunch is now making a hard pivot to small satellites, a move that, on its face, seems puzzling after going all-in on kinetic launch and even performing several impressive hardware tests, throwing a projectile to altitudes of up to 30,000 feet. Ars got the scoop, with the company’s CEO detailing why and how it plans to build a low-Earth orbit telecommunications constellation with 280 satellites.

Traditional versus kinetic … The planned constellation, named Meridian, is an opportunity for SpinLaunch to diversify away from being solely a launch company, according to David Wrenn, the company’s CEO. We’ve observed this in a number of companies that started out as rocket developers before branching out to satellite manufacturing or space services. Wrenn said SpinLaunch could loft all of the Meridian satellites on a single large conventional rocket, or perhaps two medium-lift rockets, and then maintain the constellation with its own kinetic launch system. A satellite communications network presents a better opportunity for profit, Wrenn said. “The launch market is relatively small compared to the economic potential of satellite communication,” he said. “Launch has generally been more of a cost center than a profit center. Satcom will be a much larger piece of the overall industry.”

Peter Beck suggests Electron is here to stay. The conventional wisdom is that the small launch vehicle business isn’t a big moneymaker. There is really only one company, Rocket Lab, that has gained traction in selling dedicated rides to orbit for small satellites. Rocket Lab’s launcher, Electron, can place payloads of up to a few hundred pounds into orbit. As soon as Rocket Lab had some success, SpaceX began launching rideshare missions on its much larger Falcon 9 rocket, cobbling together dozens of satellites on a single vehicle to spread the cost of the mission among many customers. This offers customers a lower price point than buying a dedicated launch on Electron. But Peter Beck, Rocket Lab’s founder and CEO, says his company has found a successful market providing dedicated launches for small satellites, despite price pressure from SpaceX, Space News reports. “Dedicated small launch is a real market, and it should not be confused with rideshare,” he argued. “It’s totally different.”

No man’s land … Some small satellite companies that can afford the extra cost of a dedicated launch realize the value of controlling their schedule and orbit, traits that a dedicated launch offers over a rideshare, Beck said. It’s easy to blame SpaceX for undercutting the prices of Rocket Lab and other players in this segment of the launch business, but Beck said companies that have failed or withdrawn from the small launch market didn’t have a good business plan, a good product, or good engineering. He added that the capacity of the Electron vehicle is well-suited for dedicated launch, whereas slightly larger rockets in the one-ton-to-orbit class—a category that includes Firefly Aerospace’s Alpha and Isar Aerospace’s Spectrum rockets—are an ill fit. The one-ton performance range is “no man’s land” in the market, Beck said. “It’s too small to be a useful rideshare mission, and it’s too big to be a useful dedicated rocket” for smallsats.

ULA scrubs first full-on Kuiper launch. A band of offshore thunderstorms near Florida’s Space Coast on Wednesday night forced United Launch Alliance to scrub a launch attempt of the first of dozens of missions on behalf of its largest commercial customer, Amazon, Spaceflight Now reports. The mission will use an Atlas V rocket to deploy 27 satellites for Amazon’s Project Kuiper network. It’s the first launch of what will eventually be more than 3,200 operational Kuiper satellites beaming broadband connectivity from space, a market currently dominated by SpaceX’s Starlink. As of Thursday, ULA hadn’t confirmed a new launch date, but airspace warning notices released by the FAA suggest the next attempt might occur Monday, April 14.

What’s a few more days? … This mission has been a long time coming. Amazon announced the Kuiper megaconstellation in 2019, and the company says it’s investing at least $10 billion in the project (the real number may be double that). Problems in manufacturing the Kuiper satellites, which Amazon is building in-house, delayed the program’s first full-on launch by a couple of years. Amazon launched a pair of prototype satellites in 2023, but the operational versions are different, and this mission fills the capacity of ULA’s Atlas V rocket. Amazon has booked more than 80 launches with ULA, Arianespace, Blue Origin, and SpaceX to populate the Kuiper network. (submitted by EllPeaTea)

Space Force swaps ULA for SpaceX. For the second time in six months, SpaceX will deploy a US military satellite that was sitting in storage, waiting for a slot on United Launch Alliance’s launch schedule, Ars reports. Space Systems Command, which oversees the military’s launch program, announced Monday that it is reassigning the launch of a Global Positioning System satellite from ULA’s Vulcan rocket to SpaceX’s Falcon 9. This satellite, designated GPS III SV-08 (Space Vehicle-08), will join the Space Force’s fleet of navigation satellites beaming positioning and timing signals for military and civilian users around the world. The move allows the GPS satellite to launch as soon as the end of May, the Space Force said. The military executed a similar rocket swap for a GPS mission that launched on a Falcon 9 in December.

Making ULA whole … The Space Force formally certified ULA’s Vulcan rocket for national security missions last month, so Vulcan may finally be on the cusp of delivering for the military. But there are several military payloads in the queue to launch on Vulcan before GPS III SV-08, which was already completed and in storage at its Lockheed Martin factory in Colorado. Meanwhile, SpaceX is regularly launching Falcon 9 rockets with ample capacity to add the GPS mission to the manifest. In exchange for losing the contract to launch this particular GPS satellite, the Space Force swapped a future GPS mission that was assigned to SpaceX to fly on ULA’s Vulcan instead.

Russia launches a former Navy SEAL to space. Jonny Kim, a former Navy SEAL, Harvard Medical School graduate, and now a NASA astronaut, blasted off with two cosmonaut crewmates aboard a Russian Soyuz rocket early Tuesday, CBS News reports. Three hours later, Kim and his Russian crewmates—Sergey Ryzhikov and Alexey Zubritsky—chased down the International Space Station and moved in for a picture-perfect docking aboard their Soyuz MS-27 spacecraft. “It was the trip of a lifetime and an honor to be here,” Kim told flight controllers during a traditional post-docking video conference.

Rotating back to Earth … Ryzhikov, Zubritsky, and Kim joined a crew of seven living aboard the International Space Station, temporarily raising the lab’s crew complement to 10 people. The new station residents are replacing an outgoing Soyuz crew—Alexey Ovchinin, Ivan Wagner, and Don Pettit—who launched to the ISS last September and who plan to return to Earth aboard their own spacecraft April 19 to wrap up a 219-day stay in space. This flight continues the practice of launching US astronauts on Russian Soyuz missions, part of a barter agreement between NASA and the Russian space agency that also reserves a seat on SpaceX Dragon missions for Russian cosmonauts.

China is littering in LEO. China’s construction of a pair of communications megaconstellations could cloud low Earth orbit with large spent rocket stages for decades or beyond, Space News reports. Launches for the government’s Guowang and Shanghai-backed but more commercially oriented Qianfan (Thousand Sails) constellation began in the second half of 2024, with each planned to consist of over 10,000 satellites, demanding more than a thousand launches in the coming years. Placing this number of satellites is enough to cause concern about space debris because China hasn’t disclosed its plans for removing the spacecraft from orbit at the end of their missions. It turns out there’s another big worry: upper stages.

An orbital time bomb … While Western launch providers typically deorbit their upper stages after dropping off megaconstellation satellites in space, China does not. This means China is leaving rockets in orbits high enough to persist in space for more than a century, according to Jim Shell, a space domain awareness and orbital debris expert at Novarum Tech. Space News reported on Shell’s commentary in a social media post, where he wrote that orbital debris mass in low-Earth orbit “will be dominated by PRC [People’s Republic of China] upper stages in short order unless something changes (sigh).” So far, China has launched five dedicated missions to deliver 90 Qianfan satellites into orbit. Four of these missions used China’s Long March 6A rocket, with an upper stage that has a history of breaking up in orbit, exacerbating the space debris problem. (submitted by EllPeaTea)

SpaceX wins another lunar lander launch deal. Intuitive Machines has selected a SpaceX Falcon 9 rocket to launch a lunar delivery mission scheduled for 2027, the Houston Chronicle reports. The upcoming IM-4 mission will carry six NASA payloads, including a European Space Agency-led drill suite designed to search for water at the lunar south pole. It will also include the launch of two lunar data relay satellites that support NASA’s so-called Near Space Network Services program. This will be the fourth lunar lander mission for Houston-based Intuitive Machines under the auspices of NASA’s Commercial Lunar Payload Services program.

Falcon 9 has the inside track … SpaceX almost certainly offered Intuitive Machines the best deal for this launch. The flight-proven Falcon 9 rocket is reliable and inexpensive compared to competitors and has already launched two Intuitive Machines missions, with a third one set to fly late this year. However, there’s another factor that made SpaceX a shoe-in for this contract. SpaceX has outfitted one of its launch pads in Florida with a unique cryogenic loading system to pump liquid methane and liquid oxygen propellants into the Intuitive Machines lunar lander as it sits on top of its rocket just before liftoff. The lander from Intuitive Machines uses these super-cold propellants to feed its main engine, and SpaceX’s infrastructure for loading it makes the Falcon 9 rocket the clear choice for launching it.

Time may finally be running out for SLS. Jared Isaacman, President Trump’s nominee for NASA administrator, said Wednesday in a Senate confirmation hearing that he wants the space agency to pursue human missions to the Moon and Mars at the same time, an effort that will undoubtedly require major changes to how NASA spends its money. My colleague Eric Berger was in Washington for the hearing and reported on it for Ars. Senators repeatedly sought Isaacman’s opinion on the Space Launch System, the NASA heavy-lifter designed to send astronauts to the Moon. The next SLS mission, Artemis II, is slated to launch a crew of four astronauts around the far side of the Moon next year. NASA’s official plans call for the Artemis III mission to launch on an SLS rocket later this decade and attempt a landing at the Moon’s south pole.

Limited runway … Isaacman sounded as if he were on board with flying the Artemis II mission as envisioned—no surprise, then, that the four Artemis II astronauts were in the audience—and said he wanted to get a crew of Artemis III to the lunar surface as quickly as possible. But he questioned why it has taken NASA so long, and at such great expense, to get its deep space human exploration plans moving. In one notable exchange, Isaacman said NASA’s current architecture for the Artemis lunar plans, based on the SLS rocket and Orion spacecraft, is probably not the ideal “long-term” solution to NASA’s deep space transportation plans. The smart reading of this is that Isaacman may be willing to fly the Artemis II and Artemis III missions as conceived, given that much of the hardware is already built. But everything that comes after this, including SLS rocket upgrades and the Lunar Gateway, could be on the chopping block.

Welcome to the club, Blue Origin. Finally, the Space Force has signaled it’s ready to trust Jeff Bezos’ space company, Blue Origin, for launching the military’s most precious satellites, Ars reports. Blue Origin received a contract April 4 to launch seven national security missions for the Space Force between 2027 and 2032, an opening that could pave the way for more launch deals in the future. These missions will launch on Blue Origin’s heavy-lift New Glenn rocket, which had a successful debut test flight in January. The Space Force hasn’t certified New Glenn for national security launches, but military officials expect to do so sometime next year. Blue Origin joins SpaceX and United Launch Alliance in the Space Force’s mix of most-trusted launch providers.

A different class … The contract Blue Origin received last week covers launch services for the Space Force’s most critical space missions, requiring rocket certification and a heavy dose of military oversight to ensure reliability. Blue Origin was already eligible to launch a separate batch of missions the Space Force set aside to fly on newer rockets. The military is more tolerant of risk on these lower-priority missions, which include launches of “cookie cutter” satellites for the Pentagon’s large fleet of missile-tracking satellites and a range of experimental payloads.

Why is SpaceX winning so many Space Force contracts? In less than a week, the US Space Force awarded SpaceX a $5.9 billion deal to make Elon Musk’s space company the Pentagon’s leading launch provider, replacing United Launch Alliance in top position. Then, the Space Force assigned the vast majority of this year’s most lucrative launch contracts to SpaceX. As we mention earlier in the Rocket Report, the military also swapped a ULA rocket for a SpaceX launch vehicle for an upcoming GPS mission. So, is SpaceX’s main competitor worried Elon Musk is tipping the playing field for lucrative government contracts by cozying up to President Trump?

It’s all good, man … Tory Bruno, ULA’s chief executive, doesn’t seem too worried in his public statements, Ars reports. In a roundtable with reporters this week at the annual Space Symposium conference in Colorado, Bruno was asked about Musk’s ties with Trump. “We have not been impacted by our competitor’s position advising the president, certainly not yet,” Bruno said. “I expect that the government will follow all the rules and be fair and follow all the laws, and so we’re behaving that way.” The reason Bruno can say Musk’s involvement in the Trump administration so far hasn’t affected ULA is simple. SpaceX is cheaper and has a ready-made line of Falcon 9 and Falcon Heavy rockets available to launch the Pentagon’s satellites. ULA’s Vulcan rocket is now certified to launch military payloads, but it reached this important milestone years behind schedule.

Two Texas lawmakers are still fighting the last war. NASA has a lot to figure out in the next couple of years. Moon or Mars? Should, or when should, the Space Launch System be canceled? Can the agency absorb a potential 50 percent cut to its science budget? If Senators John Cornyn and Ted Cruz get their way, NASA can add moving a space shuttle to its list. The Lone Star State’s two Republican senators introduced the “Bring the Space Shuttle Home Act” on Thursday, CollectSpace reports. If passed by Congress and signed into law, the bill would direct NASA to take the space shuttle Discovery from the national collection at the Smithsonian National Air and Space Museum and transport it to Space Center Houston, a museum and visitor attraction next to Johnson Space Center, home to mission control and NASA’s astronaut training base. Discovery has been on display at the Smithsonian since 2012. NASA awarded museums in California, Florida, and New York the other three surviving shuttle orbiters.

Dollars and nonsense … Moving a space shuttle from Virginia to Texas would be a logistical nightmare, cost an untold amount of money, and would create a distraction for NASA when its focus should be on future space exploration. In a statement, Cruz said Houston deserves one of NASA’s space shuttles because of the city’s “unique relationship” to the program. Cornyn alleged in a statement that the Obama administration blocked Houston from receiving a space shuttle for political reasons. NASA’s inspector general found no evidence of this. On the contrary, transferring a space shuttle to Texas now would be an unequivocal example of political influence. The Boeing 747s that NASA used to move space shuttles across the country are no longer flightworthy, and NASA scrapped the handling equipment needed to prepare a shuttle for transport. Moving the shuttle by land or sea would come with its own challenges. “I can easily see this costing a billion dollars,” Dennis Jenkins, a former shuttle engineer who directed NASA’s shuttle transition and retirement program more than a decade ago, told CollectSpace in an interview. On a personal note, the presentation of Discovery at the Smithsonian is remarkable to see in person, with aerospace icons like the Concorde and the SR-71 spy plane under the same roof. Space Center Houston can’t match that.

Rocket Report: Next Starship flight to reuse booster; FAA clears New Glenn


“The first Super Heavy reuse will be a step towards our goal of zero-touch reflight.”

Welcome to Edition 7.38 of the Rocket Report! SpaceX test fired a Super Heavy booster that launched in January on Thursday, in South Texas. This sets up the possibility of a reused Super Heavy rocket launching within the next several weeks, and would be an important step forward in the Starship launch program. It’s also a bold step given that there is a lot riding on this Starship launch, given that the last two have failed due to propulsion issues with the rocket’s upper stage.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

European commercial launch industry joins the space race. The first flight of Isar Aerospace’s Spectrum rocket didn’t last long on Sunday, Ars reports. The booster’s nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, ending the abbreviated test flight with a spectacular, fiery crash into the sea. However, it marked the beginning of something new in Europe as commercial startups begin launching rockets.

Learning to embrace failure … Isar Aerospace, based in Germany, was the first in a crop of new European rocket companies to attempt an orbital launch. Isar is one of a half-dozen or so European launch startups that could fly their orbital-class rockets in the next couple of years. Of this group, Isar has raised the most money, reporting more than 400 million euros ($430 million) of fundraising, primarily from venture capital sources. We are looking forward to the European launch industry heating up after a long period of development.

PLD Space signs launch agreement with D-Orbit. The Spanish launch company, PLD Space, announced an agreement this week with an Italy-based space transportation company, D-Orbit. As part of the agreement, D-Orbit’s ION orbital transfer vehicle will launch on PLD Space’s forthcoming rocket, the Miura 5. Although the announcement did not specify terms of the agreement, PLD Space said it has now filled “more than 80 percent” of the launch slots on its manifest until 2027.

Waiting on the rocket … The ION vehicle, essentially a dispenser of CubeSats, has previously flown several missions. The real question, therefore, concerns the readiness of the Miura 5 small rocket. PLD Space said it is currently ramping up serial production for the Miura 5 using technology from a prototype rocket, with the aim of starting its test flight campaign by the end of 2025. Commercial flights of Miura 5 could begin in 2026 with the objective of scaling up to 30 launches per year by 2030. We shall see about that.

China shooting for record number of launches. Early on Tuesday morning, a Long March 2D rocket lifted off from Jiuquan Satellite Launch Center in the Gobi Desert, Space News reports. The Shanghai Academy of Spaceflight Technology, a state-owned rocket maker, announced the success of the launch, revealing the payload to be a satellite Internet technology test satellite. Tuesday’s mission was China’s 17th orbital launch of 2025, following the launch of the classified TJS-16 satellite into geosynchronous transfer orbit on March 29 via a Long March 7A rocket.

Shooting for a century … This puts the country on pace to launch 68 rockets for the year. This is in line with China’s total orbital launches for each of the last three years (64, 67, and 68 launches respectively). However, Chinese space watcher Andrew Jones believes the country may attempt to go as high as 100 launches this year. This would be driven by growing commercial activity, megaconstellation projects, and new launcher development. A number of new, medium-lift and potentially reusable rockets are targeting debut flights this year, he reports.

Falcon 9 launches first crewed polar mission. Four adventurers suited up and embarked on a first-of-a-kind trip to space Monday night, becoming the first humans to fly in polar orbit aboard a SpaceX crew capsule chartered by a Chinese-born cryptocurrency billionaire, Ars reports. Chun Wang, born in China and now a citizen of Malta, paid SpaceX an undisclosed sum for the opportunity to fly to space and bring three hand-picked crewmates along with him. He named his mission Fram2 in honor of the Norwegian exploration ship Fram used for polar expeditions at the turn of the 20th century.

Rocket follows an unusual trajectory … The Falcon 9 rocket launched from Kennedy Space Center. However, instead of heading to the northeast in pursuit of the International Space Station, the Falcon 9 and Dragon spacecraft departed Launch Complex 39A and arced to the southeast, then turned south on a flight path hugging Florida’s east coast. The unusual trajectory aligned the Falcon 9 with a perfectly polar orbit at an inclination of 90 degrees to the equator, bringing the four-person crew directly over the North or South Pole every 45 minutes. They are the first humans to orbit over the poles.

Amazon targets April 9 for first Kuiper launch. As soon as next week, Amazon plans to send 27 of its satellites into low Earth orbit on a United Launch Alliance Atlas 5 rocket, Spaceflight Now reports. Launch is scheduled for Wednesday, April 9, during a three-hour window that opens at noon EDT (16: 00 UTC). “We’ve done extensive testing on the ground to prepare for this first mission, but there are some things you can only learn in flight, and this will be the first time we’ve flown our final satellite design and the first time we’ve deployed so many satellites at once,” said Rajeev Badyal, vice president of Project Kuiper.

Heaviest mission launched by an Atlas … This will be the first mission by United Launch Alliance of this year, and the company’s first in nearly half a year. But officials say that will change soon. In a February interview with Gary Wentz, ULA vice president of Government and Commercial Programs, said that the upcoming launch for Amazon, dubbed Kuiper 1 by ULA and Kuiper Atlas 1 (KA-01) by Amazon, was the first of many planned for the year. “We have quite a few Kuiper Atlases planned this year, as well as Kuiper Vulcans,” Wentz said. Atlas can carry 27 Kuiper satellites, and Vulcans can loft 45.

SpaceX tests previously flown Super Heavy booster. SpaceX is having trouble with Starship’s upper stage after back-to-back failures, but engineers are making remarkable progress with the rocket’s enormous booster. The most visible sign of SpaceX making headway with Starship’s first stage—called Super Heavy—came at 9: 40 am local time (10: 40 am EDT; 14: 40 UTC) Thursday at the company’s Starbase launch site in South Texas. With an unmistakable blast of orange exhaust, SpaceX fired up a Super Heavy booster that has already flown to the edge of space. The burn lasted approximately eight seconds, Ars reports.

Rocket will fly on next Starship test … This was the first time SpaceX has test-fired a “flight-proven” Super Heavy booster, and it paves the way for this particular rocket—designated Booster 14—to fly again soon. A reflight of Booster 14, which previously launched and returned to Earth in January, will happen on the next Starship launch, SpaceX confirmed Thursday. “This booster previously launched and returned on Flight 7 and 29 of its 33 Raptor engines are flight proven,” the company said. “The first Super Heavy reuse will be a step towards our goal of zero-touch reflight.” It is a legitimately and characteristically bold decision to refly a Starship booster on a test flight that SpaceX really needs to succeed. The next test may come late this month or more likely in May.

FAA closes big rocket mishap investigations. The Federal Aviation Administration (FAA) closed mishap investigations into both the SpaceX Starship flight and Blue Origin New Glenn debut that both took place on Jan. 16, Via Satellite reports. Although the FAA closed the mishap investigation regarding the January 16 Starship flight, the rocket is still grounded because there is still an open mishap investigation into the following March 7 flight. “There were no public injuries and one confirmed report of minor vehicle damage in the Turks and Caicos Islands,” the FAA said in a statement on the January 16 flight.

New Glenn closed out as well … The FAA also completed its mishap investigation of Blue Origin’s first New Glenn flight, which successfully deployed Blue Origin’s own space logistics vehicle Blue Ring. Blue Origin failed to recover the first stage booster, which triggered the mishap investigation. The first stage was not able to restart its engines, which prevented the reentry burn from occurring and caused the loss of the stage. Blue Origin has identified seven corrective actions, and the FAA will verify those have been implemented before the second mission. Blue Origin is targeting a return to flight in late spring and will attempt to land the booster again.

Artemis II one step closer to launch. The four astronauts who will fly on board NASA’s Artemis II mission unveiled the patch for their historic flight on Thursday. The four astronauts who will be the first to fly to the Moon under NASA’s Artemis campaign—Commander Reid Wiseman, pilot Victor Glover, and mission specialist Christina Koch from NASA, and mission specialist Jeremy Hansen from Canada—have designed an emblem to represent their mission that references both their distant destination and the home they will return to, the space agency said. It looks great!

Here’s what it means … “This patch designates the mission as “AII,” signifying not only the second major flight of the Artemis campaign, but also an endeavor of discovery that seeks to explore for all and by all. Framed in Apollo 8’s famous Earthrise photo, the scene of the Earth and the Moon represents the dual nature of human spaceflight, both equally compelling: The Moon represents our exploration destination, focused on discovery of the unknown. The Earth represents home, focused on the perspective we gain when we look back at our shared planet and learn what it is to be uniquely human. The orbit around Earth highlights the ongoing exploration missions that have enabled Artemis to set sights on a long-term presence on the Moon and soon, Mars.”

Rocket Report: Stoke is stoked; sovereignty is the buzzword in Europe


“The idea that we will be able to do it through America… I think is very, very doubtful.”

Welcome to Edition 7.37 of the Rocket Report! It’s been interesting to watch how quickly European officials have embraced ensuring they have a space launch capability independent of other countries. A few years ago, European government satellites regularly launched on Russian Soyuz rockets, and more recently on SpaceX Falcon 9 rockets from the United States. Russia is now non grata in European government circles, and the Trump administration is widening the trans-Atlantic rift. European leaders have cited the Trump administration and its close association with Elon Musk, CEO of SpaceX, as prime reasons to support sovereign access to space, a capability currently offered only by Arianespace. If European nations can reform how they treat their commercial space companies, there’s enough ambition, know-how, and money in Europe to foster a competitive launch industry.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Isar Aerospace aims for weekend launch. A German startup named Isar Aerospace will try to launch its first rocket Saturday, aiming to become the first in a wave of new European launch companies to reach orbit, Ars reports. The Spectrum rocket consists of two stages, stands about 92 feet (28 meters) tall, and can haul payloads up to 1 metric ton (2,200 pounds) into low-Earth orbit. Based in Munich, Isar was founded by three university graduate students in 2018. Isar scrubbed a launch attempt Monday due to unfavorable winds at the launch site in Norway.

From the Arctic … Notably, this will be the first orbital launch attempt from a launch pad in Western Europe. The French-run Guiana Space Center in South America is the primary spaceport for European rockets. Virgin Orbit staged an airborne launch attempt from an airport in the United Kingdom in 2023, and the Plesetsk Cosmodrome is located in European Russia. The launch site for Isar is named Andøya Spaceport, located about 650 miles (1,050 kilometers) north of Oslo, inside the Arctic Circle. (submitted by EllPeaTea)

A chance for competition in Europe. The European Space Agency is inviting proposals to inject competition into the European launch market, an important step toward fostering a dynamic multiplayer industry officials hope one day will mimic that of the United States, Ars reports. The near-term plan for the European Launcher Challenge is for ESA to select companies for service contracts to transport ESA and other European government payloads to orbit from 2026 through 2030. A second component of the challenge is for companies to perform at least one demonstration of an upgraded launch vehicle by 2028. The competition is open to any European company working in the launch business.

Challenging the status quo … This is a major change from how ESA has historically procured launch services. Arianespace has been the only European launch provider available to ESA and other European institutions for more than 40 years. But there are private companies across Europe at various stages of developing their own small launchers, and potentially larger rockets, in the years ahead. With the European Launcher Challenge, ESA will provide each of the winners up to 169 million euros ($182 million), a significant cash infusion that officials hope will shepherd Europe’s nascent private launch industry toward liftoff. Companies like Isar Aerospace, Rocket Factory Augsburg, MaiaSpace, and PLD Space are among the contenders for ESA contracts.

Rocket Lab launches eight satellites. Rocket Lab launched eight satellites Wednesday for a German company that is expanding its constellation to detect and track wildfires, Space News reports. An Electron rocket lifted off from New Zealand and completed deploying its payload of eight CubeSats for OroraTech about 55 minutes later, placing them into Sun-synchronous orbits at an altitude of about 341 miles (550 kilometers). This was Rocket Lab’s fifth launch of the year, and the third in less than two weeks.

Fire goggles … OroraTech launched three satellites before this mission, fusing data from those satellites and government missions to detect and track wildfires. The new satellites are designed to fill a gap in coverage in the afternoon, a peak time for wildfire formation and spread. OroraTech plans to launch eight more satellites later this year. Wildfire monitoring from space is becoming a new application for satellite technology. Last month, OroraTech partnered with Spire for a contract to build a CubeSat constellation called WildFireSat for the Canadian Space Agency. Google is backing FireSat, another constellation of more than 50 satellites to be deployed in the coming years to detect and track wildfires. (submitted by EllPeaTea)

Should Britain have a sovereign launch capability? A UK House of Lords special inquiry committee has heard from industry experts on the importance of fostering a sovereign launch capability, European Spaceflight reports. On Monday, witnesses from the UK space industry testified that the nation shouldn’t rely on others, particularly the United States, to put satellites into orbit. “The idea that we will be able to do it through America… certainly in today’s, you know, the last 50 days, I think is very, very doubtful. The UK needs access to space,” said Scott Hammond, deputy CEO of SaxaVord Spaceport in Scotland.

Looking inward … A representative from one of the most promising UK launch startups agreed. “Most people who are looking to launch are beholden to the United States solutions or services that are there,” said Alan Thompson, head of government affairs at Skyrora. “Without having our own home-based or UK-based service provider, we risk not having that voice and not being able to undertake all these experiments or be able to manifest ourselves better in space.” The UK is the only nation to abandon an independent launch capability after putting a satellite into orbit. The British government canceled the Black Arrow rocket in the early 1970s, citing financial reasons. A handful of companies, including Skyrora, is working to restore the orbital launch business to the UK.

This rocket engine CEO faces some salacious allegations. The Independent published what it described as an exclusive report Monday describing a lawsuit filed against the CEO of RocketStar, a New York-based company that says its mission is “improving upon the engines that power us to the stars.” Christopher Craddock is accused of plundering investor funds to underwrite pricey jaunts to Europe, jewelry for his wife, child support payments, and, according to the company’s largest investor, “airline tickets for international call girls to join him for clandestine weekends in Miami,” The Independent reports. Craddock established RocketStar in 2014 after financial regulators barred him from working on Wall Street over a raft of alleged violations.

Go big or go home … The $6 million lawsuit filed by former CEO Michael Mojtahedi alleges RocketStar “is nothing more than a Ponzi scheme… [that] has been predicated on Craddock’s ability to con new people each time the company has run out of money.” On its website, RocketStar says its work focuses on aerospike rocket engines and a “FireStar Fusion Drive, the world’s first electric propulsion device enhanced with nuclear fusion.” These are tantalizing technologies that have proven elusive for other rocket companies. RocketStar’s attorney told The Independent: “The company denies the allegations and looks forward to vindicating itself in court.”

Another record for SpaceX. Last Thursday, SpaceX launched a batch of clandestine SpaceX-built surveillance satellites for the National Reconnaissance Office from Vandenberg Space Force Base in California, Spaceflight Now reports. This was the latest in a series of flights populating the NRO’s constellation of low-Earth orbit reconnaissance satellites. What was unique about this mission was its use of a Falcon 9 first stage booster that flew to space just nine days prior with a NASA astronomy satellite. The successful launch broke the record for the shortest span between flights of the same Falcon 9 booster, besting a 13.5-day turnaround in November 2024.

A mind-boggling number of launches … This flight also marked the 450th launch of a Falcon 9 rocket since its debut in 2010, and the 139th within a 365-day period, despite suffering its first mission failure in nearly 10 years and a handful of other glitches. SpaceX’s launch pace is unprecedented in the history of the space industry. No one else is even close. In the last Rocket Report I authored, I wrote that SpaceX’s steamroller no longer seems to be rolling downhill. That may be the case as the growth in the Falcon 9 launch cadence has slowed, but it’s hard for me to see anyone else matching SpaceX’s launch rate until at least the 2030s.

Rocket Lab and Stoke Space find an on-ramp. Space Systems Command announced Thursday that it selected Rocket Lab and Stoke Space to join the Space Force’s National Security Space Launch (NSSL) program. The contracts have a maximum value of $5.6 billion, and the Space Force will dole out “task orders” for individual missions as they near launch. Rocket Lab and Stoke Space join SpaceX, ULA, and Blue Origin as eligible launch providers for lower-priority national security satellites, a segment of missions known as Phase 3 Lane 1 in the parlance of the Space Force. For these missions, the Space Force won’t require certification of the rockets, as the military does for higher-value missions in the so-called “Lane 2” segment. However, Rocket Lab and Stoke Space must complete at least one successful flight of their new Neutron and Nova rockets before they are cleared to launch national security payloads.

Stoked at Stoke … This is a big win for Rocket Lab and Stoke. For Rocket Lab, it bolsters the business case for the medium-class Neutron rocket it is developing for flights from Wallops Island, Virginia. Neutron will be partially reusable with a recoverable first stage. But Rocket Lab already has a proven track record with its smaller Electron launch vehicle. Stoke hasn’t launched anything, and it has lofty ambitions for a fully reusable two-stage rocket called Nova. This is a huge vote of confidence in Stoke. When the Space Force released its invitation for an on-ramp to the NSSL program last year, it said bidders must show a “credible plan for a first launch by December 2025.” Smart money is that neither company will launch its rockets by the end of this year, but I’d love to be proven wrong.

Falcon 9 deploys spy satellite. Monday afternoon, a SpaceX Falcon 9 took flight from Florida’s Space Coast and delivered a national security payload designed, built, and operated by the National Reconnaissance Office into orbit, Florida Today reports. Like almost all NRO missions, details about the payload are classified. The mission codename was NROL-69, and the launch came three-and-a-half days after SpaceX launched another NRO mission from California. While we have some idea of what SpaceX launched from California last week, the payload for the NROL-69 mission is a mystery.

Space sleuthing … There’s an online community of dedicated skywatchers who regularly track satellites as they sail overhead around dawn and dusk. The US government doesn’t publish the exact orbital parameters for its classified spy satellites (they used to), but civilian trackers coordinate with one another, and through a series of observations, they can produce a pretty good estimate of a spacecraft’s orbit. Marco Langbroek, a Dutch archeologist and university lecturer on space situational awareness, is one of the best at this, using publicly available information about the flight path of a launch to estimate when the satellite will fly overhead. He and three other observers in Europe managed to locate the NROL-69 payload just two days after the launch, plotting the object in an orbit between 700 and 1,500 kilometers at an inclination of 64.1 degrees to the equator. Analysts speculated this mission might carry a pair of naval surveillance spacecraft, but this orbit doesn’t match up well with any known constellations of NRO satellites.

NASA continues with Artemis II preps. Late Saturday night, technicians at Kennedy Space Center in Florida moved the core stage for NASA’s second Space Launch System rocket into position between the vehicle’s two solid-fueled boosters, Ars reports. Working inside the iconic 52-story-tall Vehicle Assembly Building, ground teams used heavy-duty cranes to first lift the butterscotch orange core stage from its cradle, then rotate it to a vertical orientation and lift it into a high bay, where it was lowered into position on a mobile launch platform. The 212-foot-tall (65-meter) core stage is the largest single hardware element for the Artemis II mission, which will send a team of four astronauts around the far side of the Moon and back to Earth as soon as next year.

Looking like a go … With this milestone, the slow march toward launch continues. A few months ago, some well-informed people in the space community thought there was a real possibility the Trump administration could quickly cancel NASA’s Space Launch System, the high-priced heavy-lifter designed to send astronauts from the Earth to the Moon. The most immediate possibility involved terminating the SLS program before it flies with Artemis II. This possibility appears to have been overcome by circumstances. The rockets most often mentioned as stand-ins for the Space Launch System—SpaceX’s Starship and Blue Origin’s New Glenn—aren’t likely to be cleared for crew missions for at least several years. The long-term future of the Space Launch System remains in doubt.

Space Force says Vulcan is good to go. The US Space Force on Wednesday announced that it has certified United Launch Alliance’s Vulcan rocket to conduct national security missions, Ars reports. “Assured access to space is a core function of the Space Force and a critical element of national security,” said Brig. Gen. Kristin Panzenhagen, program executive officer for Assured Access to Space, in a news release. “Vulcan certification adds launch capacity, resiliency, and flexibility needed by our nation’s most critical space-based systems.” The formal announcement closes a yearslong process that has seen multiple delays in the development of the Vulcan rocket, as well as two anomalies in recent years that were a further setback to certification.

Multiple options … This certification allows ULA’s Vulcan to launch the military’s most sensitive national security missions, a separate lot from those Rocket Lab and Stoke Space are now eligible for (as we report in a separate Rocket Report entry). It elevates Vulcan to launch these missions alongside SpaceX’s Falcon 9 and Falcon Heavy rockets. Vulcan will not be the next rocket that the company launches, however. First up is one of the company’s remaining Atlas V boosters, carrying Project Kuiper broadband satellites for Amazon. This launch could occur in April, although ULA has not set a date. This will be followed by the first Vulcan national security launch, which the Space Force says could occur during the coming “summer.”

Welcome to Edition 7.36 of the Rocket Report! Well, after nine months, NASA astronauts Butch Wilmore and Suni Williams are finally back on Earth, safe and sound. This brings to conclusion one of the stranger and more dramatic human spaceflight stories in years. We’re glad they’re finally home, soon to be reunited with their families.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Summary of 2024 launch activity. In its annual launch report, released earlier this month, Bryce Tech analyzed the 259 orbital launches conducted last year. Among the major trends the analysts found were: Nearly 60 percent of all launches were conducted by US providers, Commercial providers accounted for about 70 percent of launches, and Small satellites, primarily for communications, represented the majority of all spacecraft launched at 97 percent.

Trends dominated by Starlink launches … SpaceX conducted more than half of the launches last year (134), putting 2,390 spacecraft into orbit (the vast majority of which were Starlink satellites). The next closest competitor was China, with 48 launches and 186 spacecraft. The nearest US competitor to SpaceX was Rocket Lab, with 14 launches and 33 spacecraft. The competition in “upmass,” that is total kg lofted into orbit, was less close still. SpaceX put 1.86 million kg into space, followed by China (164,000 kg) and Roscosmos (76,000). The closest US competitor was United Launch Alliance, at 29,000 kg. Put another way, for every kilogram ULA put into orbit, SpaceX lofted 66.

MaiaSpace inks first commercial customer. MaiaSpace, a French subsidiary of ArianeGroup founded in 2022, signed an agreement to fly multiple missions for Exotrail’s SpaceVan orbital transfer vehicle beginning in 2027. The partnership with Exotrail provides an early vote of confidence that the reusable Maia rocket can increase Europe’s sovereign launch capabilities, Payload reports. This is one of several launch agreements signed recently by Exotrail.

Hitting the trail … Exotrail flew its first SpaceVan mission on SpaceX’s Transporter-9 flight in November 2023 and deployed the Endurosat-built “EXO-0” cubesat in LEO after three months in orbit. In November, the company signed a deal with Arianespace to launch Exotrail’s first SpaceVan mission to geostationary transfer orbit in the latter half of 2026. After leaving Ariane 64, SpaceVan will tow a customer satellite to GEO, demonstrating its ability to deliver satellites to the full range of orbital trajectories. (submitted by gma)

Electron launches twice in three days. Rocket Lab completed the deployment of a constellation of Internet of Things satellites for French company Kinéis with an Electron launch on Monday. The launch was the fifth and final mission under a contract signed by the companies in 2021. Each launch carried five satellites, weighing 28 kilograms each, to complete a 25-satellite constellation.

Continuing to steadily increase cadence … For Rocket Lab, this was the second launch in a little more than 72 hours, after another Electron launched a radar imaging satellite for Japanese company iQPS March 14. It was the fourth launch so far this year for Rocket Lab, which previously stated it expects to perform more than 20 Electron launches, including the HASTE suborbital version, this year.

Pangea raises Series A funding. The Spanish startup announced this week that it has raised 23 million euros ($25 million) in Series A funding, European Spaceflight reports. This funding includes contributions from former ArianeGroup CEO André-Hubert Roussel. Founded in 2018, Pangea Aerospace initially aimed to develop Meso, a small rocket designed to deliver 400 kilograms to low-Earth orbit. The rocket was to be powered by a unique, in-house-developed methalox aerospike engine.

Twice the size … However, in early 2023, the company announced it had abandoned the development of Meso to focus on providing propulsion systems for rockets and in-orbit applications. Pangea is currently in the process of developing ARCOS, an aerospike engine designed for use aboard the booster and/or upper stage of a rocket. According to Pangea, the funding will be used to “accelerate its expansion in the European market,” aiming to grow its customer base. It will look to double its workforce and scale up its manufacturing, integration, and testing capabilities.

Relativity Space eyeing move to Texas. As he consolidates control over Relativity Space, new owner and chief executive Eric Schmidt is planning significant changes at the launch company, including a likely move to the Lone Star State, Ars reports. The company faces several major challenges as it seeks to bring the Terran R rocket to market, particularly in logistics. This is because Terran R is a large launch vehicle, too large to move across the country by highway.

Watching for Baytown … The company’s initial plan was to manufacture first stages at its massive factory in Long Beach, California, and ship them through the Panama Canal to a test site at the Stennis Space Center in southern Mississippi. From there, they would be moved by barge again to the launch site in Florida. But this was expensive and time-consuming. Two sources have indicated that Relativity Space will likely move a significant portion of its Terran R manufacturing to Baytown, Texas, which is near Houston. Such a location would provide water access on the right side of the Panama Canal. Relativity has not made a formal announcement.

Crew-10 launches to ISS. A Falcon 9 rocket launched four astronauts safely into orbit on Friday evening, marking the official beginning of the Crew-10 mission to the International Space Station. Friday’s launch came two days after an initial attempt was scrubbed on Wednesday evening, Ars reports. This was due to a hydraulic issue with the ground systems that handle the Falcon 9 rocket at Launch Complex 39A in Florida.

Smooth ride to orbit … There were no technical issues on Friday, and with clear skies, NASA astronauts Anne McClain and Nichole Ayers, Japanese astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov rocketed smoothly into orbit. Although any crew launch into orbit is notable, this mission came with an added bit of importance as its success cleared the way for two NASA astronauts, Butch Wilmore and Suni Williams, to finally return home from space after a saga spanning nine months. They did so on Tuesday evening.

SpaceX pushes Falcon 9 booster reuse record. On March 12 a Falcon 9 rocket first stage made its third launch, lofting the SPHEREx and PUNCH missions into low-Earth orbit for NASA. Following the successful launch, the first stage landed near the launch site at Vandenberg Space Force Base in California. Now, this same stage could launch again on Thursday night from Vandenberg, carrying the NROL-57 mission for the US Space Force.

Rapid reuse is a thing … The launch is scheduled for 06: 49 UTC, and if it takes place it would be just nine days and four hours since the SPHEREx mission. This would shatter the company’s previous booster turnaround, set in November, of a little more than 13 days. The fast turnaround was no doubt enabled by landing the booster back near the launch site, speeding the process of inspecting and refurbishing the rocket. It’s also impressive that the Space Force greenlit such a fast turnaround time for a national security payload.

And launch pad turnaround, too. SpaceX launched its latest batch of Starlink satellites from Cape Canaveral Space Force Station at sunrise Saturday morning. The mission marked a record-breaking turnaround for launch operations at Space Launch Complex 40, Spaceflight Now reports. The launch of 23 Starlink Version 2 Mini satellites came two days, eight hours, 59 minutes, and 40 seconds after the launch of the Starlink 12-21 mission. This beat SpaceX’s previous turnaround time at that pad by nearly six hours.

Ever pushing forward … Recently, Ars covered a recent string of issues with the Falcon 9 rocket, notably with its upper stage. The principal reason is that SpaceX continues to push the envelope with even its mature products like the Falcon 9 rocket, which is now nearly 15 years old. While we can take note of issues, it’s also worth celebrating the incredibly hard work that goes into pushing cadence and turnaround times. Moreover, success with the Falcon 9 rocket supports the notion that, one day, SpaceX will be able to reach a high cadence of operations with Starship.

The Jeff and the Donald. Over the past year, Amazon and Blue Origin founder Bezos has executed a sharp public reversal in his relationship with President Trump—whom he previously criticized as a “threat to democracy”—that has surprised even longtime associates. An article in the Financial Times explores this change, and finds that it is likely due, at least in part, to Bezos’ interest in his space company. There are some spicy, and to my sense of things, accurate comments that explain why Bezos has sought to curry favor with Trump.

One longtime adviser cautions … “He cares most about Blue Origin. His chance of being the player he wants to become in space could be destroyed” if the world’s richest man (Elon Musk) and most powerful politician united against him. “The growth trajectory for the entire enterprise depends on the federal contract… otherwise Blue is dead in the water.” Another close associate says that any move by Trump to deprioritize lunar missions in favor of Musk’s aspirations to reach Mars would have a significant impact on the company’s viability and success. “It is what he has always dreamt of. Nothing will hurt Jeff financially—Blue is a money loser. It is more the opportunity to be involved.”

Welcome to Edition 7.35 of the Rocket Report! SpaceX’s steamroller is still rolling, but for the first time in many years, it doesn’t seem like it’s rolling downhill. After a three-year run of perfect performance—with no launch failures or any other serious malfunctions—SpaceX’s Falcon 9 rocket has suffered a handful of issues in recent months. Meanwhile, SpaceX’s next-generation Starship rocket is having problems, too. Kiko Dontchev, SpaceX’s vice president of launch, addressed some (but not all) of these concerns in a post on X this week. Despite the issues with the Falcon 9, SpaceX has maintained a remarkable launch cadence. As of Thursday, SpaceX has launched 28 Falcon 9 flights since January 1, ahead of last year’s pace.

Alpha rocket preps for weekend launch. While Firefly Aerospace is making headlines for landing on the Moon, its Alpha rocket is set to launch again as soon as Saturday morning from Vandenberg Space Force Base, California. The two-stage, kerosene-fueled rocket will launch a self-funded technology demonstration satellite for Lockheed Martin. It’s the first of up to 25 launches Lockheed Martin has booked with Firefly over the next five years. This launch will be the sixth flight of an Alpha rocket, which has become a leader in the US commercial launch industry for dedicated missions with 1 ton-class satellites.

Firefly’s OG … The Alpha rocket was Firefly’s first product, and it has been a central piece of the company’s development since 2014. Like Firefly itself, the Alpha rocket program has gone through multiple iterations, including a wholesale redesign nearly a decade ago. Sure, Firefly can’t claim any revolutionary firsts with the Alpha rocket, as it can with its Blue Ghost lunar lander. But without Alpha, Firefly wouldn’t be where it is today. The Texas-based firm is one of only four US companies with an operational orbital-class rocket. One thing to watch for is how quickly Firefly can ramp up its Alpha launch cadence. The rocket only flew once last year.

Isar Aerospace celebrates another win. In last week’s Rocket Report, we mentioned that the German launch startup Isar Aerospace won a contract with a Japanese company to launch a 200-kilogram commercial satellite in 2026. But wait, there’s more! On Wednesday, the Norwegian Space Agency announced it awarded a contract to Isar Aerospace for the launch of a pair of satellites for the country’s Arctic Ocean Surveillance initiative, European Spaceflight reports. The satellites are scheduled to launch on Isar’s Spectrum rocket from Andøya Spaceport in Norway by 2028.

First launch pending … These recent contract wins are a promising sign for Isar Aerospace, which is also vying for contracts to launch small payloads for the European Space Agency. The Spectrum rocket could launch on its inaugural flight within a matter of weeks, and if successful, it could mark a transformative moment for the European space industry, which has long been limited to a single launch provider: the French company Arianespace.

Mother Nature holds up Oz launch. The first launch by Gilmour Space has been postponed again due to a tropical cyclone that brought severe weather to Australia’s Gold Coast region earlier this month, InnovationAus.com reports. Tropical Cyclone Alfred didn’t significantly impact Gilmour’s launch site, but the storm did cause the company to suspend work at its corporate headquarters in Southeast Queensland. With the storm now over, Gilmour is reassessing when it might be ready to launch its Eris rocket. Reportedly, the delay could be as long as two weeks or more.

A regulatory storm … Gilmour aims to become the first Australian company to launch a rocket into orbit. Last month, Gilmour announced the launch date for the Eris rocket was set for no earlier than March 15, but Tropical Cyclone Alfred threw this schedule out the window. Gilmour said it received a launch license from the Australian Space Agency in November and last month secured approvals to clear airspace around the launch site. But there’s still a hitch. The license is conditional on final documentation for the launch being filed and agreed with the space agency, and this process is stretching longer than anticipated. (submitted by ZygP)

What is going on at SpaceX? As we mention in the introduction to this week’s Rocket Report, it has been an uncharacteristically messy eight months for SpaceX. These speed bumps include issues with the Falcon 9 rocket’s upper stage on three missions, two lost Falcon 9 boosters, and consecutive failures of SpaceX’s massive Starship rocket on its first two test flights of the year. So what’s behind SpaceX’s bumpy ride? Ars wrote about the pressures facing SpaceX employees as Elon Musk pushes his workforce ever-harder to accelerate toward what Musk might call a multi-planetary future.

Headwinds or tailwinds? … No country or private company ever launched as many times as SpaceX flew its fleet of Falcon 9 rockets in 2024. At the same time, the company has been attempting to move its talented engineering team off the Falcon 9 and Dragon programs and onto Starship to keep that ambitious program moving forward. This is all happening as Musk has taken on significant roles in the Trump administration, stirring controversy and raising questions about his motives and potential conflicts of interest. However, it may be not so much Musk’s absence from SpaceX that is causing these issues but more the company’s relentless culture. As my colleague Eric Berger suggested in his piece, it seems possible that, at least for now, SpaceX has reached the speed limit for commercial spaceflight.

A titan of Silicon Valley enters the rocket business. Former Google chief executive Eric Schmidt has taken a controlling interest in the Long Beach, California-based Relativity Space, Ars reports. Schmidt’s involvement with Relativity has been quietly discussed among space industry insiders for a few months. Multiple sources told Ars that he has largely been bankrolling the company since the end of October, when the company’s previous fundraising dried up. Now, Schmidt is Relativity’s CEO.

Unclear motives … It is not immediately clear why Schmidt is taking a hands-on approach at Relativity. However, it is one of the few US-based companies with a credible path toward developing a medium-lift rocket that could potentially challenge the dominance of SpaceX and its Falcon 9 rocket. If the Terran R booster becomes commercially successful, it could play a big role in launching megaconstellations. Schmidt’s ascension also means that Tim Ellis, the company’s co-founder, chief executive, and almost sole public persona for nearly a decade, is now out of a leadership position.

Falcon 9 deploys NASA’s newest space telescope. Satellites come in all shapes and sizes, but there aren’t any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about how the Universe, and ultimately life, came to be, Ars reports. The SPHEREx satellite rocketed into orbit from California aboard a SpaceX Falcon 9 rocket, beginning a two-year mission surveying the sky in search of clues about the earliest periods of cosmic history, when the Universe rapidly expanded and the first galaxies formed. SPHEREx will also scan for pockets of water ice within our own galaxy, where clouds of gas and dust coalesce to form stars and planets.

Excess capacity … SPHEREx has lofty goals, but it’s modest in size, weighing just a little more than a half-ton at launch. This meant the Falcon 9 rocket had plenty of extra room for four other small satellites that will fly in formation to image the solar wind as it travels from the Sun into the Solar System. The four satellites are part of NASA’s PUNCH mission. SPHEREx and PUNCH are part of NASA’s Explorers program, a series of cost-capped science missions with a lineage going back to the dawn of the Space Age. SPHEREx and PUNCH have a combined cost of about $638 million. (submitted by EllPeaTea)

China has launched another batch of Internet satellites. A new group of 18 satellites entered orbit Tuesday for the Thousand Sails constellation with the first launch from a new commercial launch pad, Space News reports. The satellites launched on top of a Long March 8 rocket from Hainan Commercial Launch Site near Wenchang on Hainan Island. The commercial launch site has two pads, the first of which entered service with a launch last year. This mission was the first to launch from the other pad at the commercial spaceport, which is gearing up for an uptick in Chinese launch activity to continue deploying satellites for the Thousand Sails network and other megaconstellations.

Sailing on … The Thousand Sails constellation, also known as Qianfan, or G60 Starlink, is a broadband satellite constellation spearheaded by Shanghai Spacecom Satellite Technology (SSST), also known as Spacesail, Space News reported. The project, which aims to deploy 14,000 satellites, seeks to compete in the global satellite Internet market. Spacesail has now launched 90 satellites into near-polar orbits, and the operator previously stated it aims to have 648 satellites in orbit by the end of 2025. If Spacesail continues launching 18 satellites per rocket, this goal would require 31 more launches this year. (submitted by EllPeaTea)

NASA, SpaceX call off astronaut launch. With the countdown within 45 minutes of launch, NASA called off an attempt to send the next crew to the International Space Station Wednesday evening to allow more time to troubleshoot a ground system hydraulics issue, CBS News reports. During the countdown Wednesday, SpaceX engineers were troubleshooting a problem with one of two clamp arms that hold the Falcon 9 rocket to its strongback support gantry. Hydraulics are used to retract the two clamps prior to launch.

Back on track … NASA confirmed Thursday SpaceX ground teams completed inspections of the hydraulics system used for the clamp arm supporting the Falcon 9 rocket and successfully flushed a suspected pocket of trapped air in the system, clearing the way for another launch attempt Friday evening. This mission, known as Crew-10, will ferry two NASA astronauts, a Japanese mission specialist, and a Russian cosmonaut to the space station. They will replace a four-person crew currently at the ISS, including Butch Wilmore and Suni Williams, who have been in orbit since last June after flying to space on Boeing’s Starliner capsule. Starliner returned to Earth without its crew due to a problem with overheating thrusters, leaving Wilmore and Williams behind to wait for a ride home with SpaceX.

SpaceX’s woes reach Poland’s space agency. The president of the Polish Space Agency, Grzegorz Wrochna, has been dismissed following a botched response to the uncontrolled reentry of a Falcon 9 second stage that scattered debris across multiple locations in Poland, European Spaceflight reports. The Falcon 9’s upper stage was supposed to steer itself toward a controlled reentry last month after deploying a set of Starlink satellites, but a propellant leak prevented it from doing so. Instead, the stage remained in orbit for nearly three weeks before falling back into the atmosphere February 19, scattering debris fragments at several locations in Poland.

A failure to communicate … In the aftermath of the Falcon 9’s uncontrolled reentry, the Polish Space Agency (POLSA) claimed it sent warnings of the threat of falling space debris to multiple departments of the Polish government. One Polish ministry disputed this claim, saying it was not adequately warned about the uncontrolled reentry. POLSA later confirmed it sent information regarding the reentry to a wrong email address. Making matters worse, the Polish Space Agency reported it was hacked on March 2. The Polish government apparently had enough and fired the head of the space agency March 11.

Vulcan booster anomaly blamed on “manufacturing defect.” The loss of a solid rocket motor nozzle on the second flight of United Launch Alliance’s Vulcan Centaur last October was caused by a manufacturing defect, Space News reports. In a roundtable with reporters Wednesday, ULA chief executive Tory Bruno said the problem has been corrected as the company awaits certification of the Vulcan rocket by the Space Force. The nozzle fell off the bottom of one of the Vulcan launcher’s twin solid rocket boosters about a half-minute into its second test flight last year. The rocket continued its climb into space, but ULA and Northrop Grumman, which supplies solid rocket motors for Vulcan, set up an investigation to find the cause of the nozzle malfunction.

All the trimmings … Bruno said the anomaly was traced to a “manufacturing defect” in one of the internal parts of the nozzle, an insulator. Specific details, he said, remained proprietary, according to Space News. “We have isolated the root cause and made appropriate corrective actions,” he said, which were confirmed in a static-fire test of a motor at a Northrop test site in Utah in February. “So we are back continuing to fabricate hardware and, at least initially, screening for what that root cause was.” Bruno said the investigation was aided by recovery of hardware that fell off the motor while in flight and landed near the launch pad in Florida, as well as “trimmings” of material left over from the manufacturing process. ULA also recovered both boosters from the ocean so engineers could compare the one that lost its nozzle to the one that performed normally. The defective hardware “just stood out night and day,” Bruno said. “It was pretty clear that that was an outlier, far out of family.” Meanwhile, ULA has trimmed its launch forecast for this year, from a projection of up to 20 launches down to a dozen.

Welcome to Edition 7.34 of the Rocket Report! What a day in space Thursday was. During the morning hours we saw the triumphant second flight of the Ariane 6 rocket, a pivotal moment for European sovereignty in space. Then Intuitive Machines had a partially successful landing on the Moon. And finally, on Thursday evening, SpaceX’s Starship failed during its second consecutive test flight.

Firefly sets date for next Alpha launch. Having completed a static-fire test, Firefly Aerospace has set a target date of March 15 for the launch of its “Message in a Booster” mission. The Alpha rocket will launch Lockheed Martin’s LM 400 spacecraft from Vandenberg Space Force Base, with the 52-minute launch window opening at 6: 25 am PT (14: 25 UTC). Lockheed is self-funding the demonstration mission of its new satellite bus, the LM 400, which it says can serve civil, military, and commercial customers.

A slow build … This is Alpha’s second launch for Lockheed Martin, and the first of Firefly’s multi-launch agreement with the company that includes up to 25 missions over the next five years. Alpha is capable of lifting 1 metric ton to low-Earth orbit, and this will be the rocket’s sixth launch since its debut in September 2021. The company has recorded one failure, two partial failures, and two successes during the time. It’s been a slow ramp up for Alpha, with the rocket having launched just a single time in 2024, in July.

Isar Aerospace wins Asian launch contract. A Japanese microgravity services startup named ElevationSpace has become the first Asian customer for Germany’s Isar Aerospace, Space News reports. ElevationSpace said Monday it has booked a launch during the second half of 2026 with Isar Aerospace for AOBA, a 200-kilogram spacecraft designed to test a recoverable platform for space-based experiments and manufacturing. This is a hopeful sign that European startups will have commercial appeal beyond the continent.

Spectrum rocket nearing debut launch … The Japanese firm cited Isar Aerospace’s direct injection capability into low Earth orbit and flexible launch scheduling as key factors in its decision to sign the contract. Isar Aerospace said last month that Spectrum, designed to deliver up to 1,000 kilograms to low-Earth orbit, has completed static-fire testing and is prepared for its first flight from Andøya Spaceport in northern Norway, pending final regulatory approval.

A small launch site in French Guiana. The French space agency, CNES, has opened a public consultation period for the new multi-user micro-launcher facility at the Guiana Space Centre in French Guiana, European Spaceflight reports. Last month, the first of four public consultation sessions into the construction of the new Multi-Launcher Launch Complex at the Guiana Space Centre was held at Kourou Town Hall. In March 2021, CNES announced plans to transform the old Diamant launch site into a new multi-use facility for commercial micro-launcher providers, supporting rockets with payloads of up to 1,500 kilograms.

Lots of potential users … The final mission launched from the Guiana Space Centre’s Diamant facility lifted off in 1976, after which it was abandoned and left to be reclaimed by the jungle. In 2019, the site was earmarked for revitalization to serve as a testing ground for the Callisto and Themis reusable rocket booster demonstrators. This testing was, however, always going to serve as a temporary justification for the launch facility’s rebirth. In July 2022, CNES pre-selected Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude to use the facility. However, MaiaSpace has since allocated the Guiana Space Centre’s old Soyuz launch pad for its partially reusable Maia rocket.

Firefly nets Earth science launch contract. Amid its successful lunar landing, forthcoming Alpha launch, and a new launch contract, Firefly is having one heck of a week. NASA revealed this week that it has selected Firefly Aerospace to launch a trio of Earth science smallsats that will study the formation of storms, Space News reports. The agency said March 4 that it awarded a task order through its Venture-Class Acquisition of Dedicated and Rideshare (VADR) contract to Firefly to launch the three-satellite Investigation of Convective Updrafts mission.

Hello, Virginia … NASA did not disclose the value of the task order, a practice it has followed on other VADR awards. The three satellites will launch on a Firefly Alpha rocket from Wallops Flight Facility in Virginia. NASA did not disclose a launch date in its announcement, but Firefly, in its own statement, said the launch would take place as soon as 2026. Firefly said it will launch the mission from Pad 0A at the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia, which has been used by Northrop Grumman’s Antares rocket and will also be used by Alpha and the future MLV rocket.

Ariane 6 delivers for Europe when it is needed. Europe’s Ariane 6 rocket lifted off Thursday from French Guiana and deployed a high-resolution reconnaissance satellite into orbit for the French military, notching a success on its first operational flight. “This is an absolute pleasure for me today to announce that Ariane 6 has successfully placed into orbit the CSO-3 satellite,” said David Cavaillolès, who took over in January as CEO of Arianespace, the Ariane 6’s commercial operator. “Today, here in Kourou, we can say that thanks to Ariane 6, Europe and France have their own autonomous access to space back, and this is great news.”

Can no longer rely on US rockets … This was the second flight of Europe’s new Ariane 6 rocket, following a mostly successful debut launch last July. The first test flight of the unproven Ariane 6 carried a batch of small, relatively inexpensive satellites. An auxiliary propulsion unit (APU)—essentially a miniature second engine—on the upper stage shut down in the latter portion of the inaugural Ariane 6 flight, after the rocket reached orbit and released some of its payloads. Philippe Baptiste, France’s minister for research and higher education, says Ariane 6 is “proof of our space sovereignty,” as many European officials feel they can no longer rely on the United States.

US launch facilities are not prepared for a surge. Rocket firm executives warned this week that the nation’s primary launch facilities may soon be unable to handle the projected surge in rocket launches, potentially hampering America’s competitiveness in the rapidly expanding commercial space sector, Space News reports. “I don’t think that people realize how many rockets are going to be launching five or eight years from now,” Dave Limp, CEO of Blue Origin, said at the Air & Space Forces Association’s Warfare Conference in Aurora, Colorado.

Support needed for multiple daily launches … Limp’s concerns were echoed by executives from SpaceX and United Launch Alliance during a panel discussion, where all three agreed that the industry must collectively prepare for a future where multiple daily launches become the norm. Jon Edwards, SpaceX’s vice president of Falcon launch vehicles, highlighted that even at Cape Canaveral, the busiest US spaceport, current protocols don’t allow simultaneous launches by different providers.

Falcon 9 first stage fails to land safely. After what appeared to be a routine Starlink mission on Sunday, a Falcon 9 first stage landed on the Just Read the Instructions drone ship in the Atlantic Ocean. Shortly after the landing, however, a fire broke out in the aft end of the rocket. This damaged a landing leg and caused the rocket to topple over. Florida Today has video of the badly damaged rocket returning to Port Canaveral.

Space remains hard … The Starlink satellites safely reached orbit, so this did not impact the primary mission. However, Falcon 9 landings have become so seemingly routine, such a failure now stands out. This booster was relatively new, having launched three Starlink missions, GOES-U, and Maxar 3. It was only the first-stage booster’s fifth flight. To date, SpaceX has successfully flown a single booster 26 times.

India begins construction of a new launch site. The Indian space agency, ISRO, presently has two operational launch pads at the Satish Dhawan Space Centre in Sriharikota. The space agency launches Indian and foreign satellites aboard rockets like PSLV and GSLV from here. As it seeks to expand its launch activities, ISRO officially began constructing a new launch site at Kulasekaranpattinam, in Tamil Nadu, this week, The National reports.

Avoiding the dogs … The Kulasekaranpattinam launch site is strategically located near the equator. With open seas to the south of it, the site allows for direct southward launches over the Indian Ocean. This will minimize fuel consumption and maximize payload capacity for small satellite launch vehicles, particularly beneficial for cost-effective commercial satellite launches. The site also avoids the need for complex “dogleg” maneuvers around Sri Lanka.

SpaceX launches Starship on its eighth flight. SpaceX launched the eighth full-scale test flight of its enormous Starship rocket on Thursday evening after receiving regulatory approval from the Federal Aviation Administration. The test flight sought a repeat of what SpaceX hoped to achieve on the previous Starship launch in January, when the rocket broke apart and showered debris over the Atlantic Ocean and Turks and Caicos Islands.

Alas … Unfortunately for SpaceX, the Starship upper stage failed again, in a similar location, with similar impacts. About a minute before reaching the cutoff of the vehicle’s engines en route to space, the upper stage spun out of control and broke apart. “During Starship’s ascent burn, the vehicle experienced a rapid unscheduled disassembly and contact was lost,” SpaceX said in a statement about an hour later. “Our team immediately began coordination with safety officials to implement pre-planned contingency responses.” Ars will have full coverage of what is a serious setback for the company.

Amazon culture comes to Blue Origin. Jeff Bezos has moved to introduce a tough Amazon-like approach to his rocket maker Blue Origin, as the world’s third-richest person seeks to revive a company that has lagged behind Elon Musk’s SpaceX, the Financial Times reports. The space company’s founder and sole shareholder has pushed to shift its internal culture with management hires from Amazon, while implementing policies akin to the e-commerce giant, including longer working hours and more aggressive targets.

Work-life balance, what? … Key to Bezos’s effort is chief executive Dave Limp. The former Amazon devices chief was appointed in late 2023 and has been followed in quick succession by several veterans from the $2.2 trillion tech giant, including supply chain chief Tim Collins, chief information officer Josh Koppelman, and chief financial officer Allen Parker. The changes in leadership have been accompanied by significant layoffs. In February, roughly 10 percent of Blue Origin’s more than 10,000-strong workforce was dismissed. Employees are now expected to work longer hours, and badge scanners have been introduced to track employee time similar to Amazon.

Space Force is to blame for Vulcan delays? The debut of United Launch Alliance’s Vulcan rocket was delayed more than four years, ultimately from 2019 to January 2024. The first flight went very well, but during the second certification mission in October 2024 there was an anomaly with one of the two solid rocket boosters powering the vehicle. Although the rocket reached its intended orbit, this issue necessitated an investigation. Vulcan has yet to fly again, and with the certification process still ongoing, it is now likely to launch no earlier than sometime this summer.

Spacecraft end up moving to the right … No one is more interested in seeing Vulcan fly than the US Space Force, which has dozens of missions lined up for the rocket. These missions were supposed to be launched between 2022 and 2026. To make up for lost time, the Space Force now hopes to launch 11 national security missions this year (this almost certainly won’t happen). In a curious comment to Space News, Bruno appeared to put some of the blame for delays on the Space Force, rather than Vulcan’s tardiness: Bruno pointed out there is inherent unpredictability in national security launch schedules, noting that “about half of the spacecraft end up needing to move right, and they move right by a lot.” It is a weird comment to make with a rocket that is years late.

Welcome to Edition 7.33 of the Rocket Report! Phew, what a week for Rocket Lab! The company released a bevy of announcements in conjunction with its quarterly earnings report Thursday. Rocket Lab is spending a lot of money to develop the medium-lift rocket Neutron rocket, and as we’ll discuss below, a rocket landing platform and a new satellite design. For now, the company is sticking by its public statements that the Neutron rocket will launch this year—the official line is it will debut in the second half of 2025—but this schedule assumes near-perfect execution on the program. “We’ve always been clear that we run aggressive schedules,” said Peter Beck, Rocket Lab’s founder and CEO. The official schedule doesn’t quite allow me to invoke a strict interpretation of Berger’s Law, which states that if a rocket’s debut is predicted to happen in the fourth quarter of a year, and that quarter is six or more months away, the launch will be delayed. However, the spirit of the law seems valid here. This time last year, Rocket Lab targeted a first launch by the end of 2024, an aggressive target that has come and gone.

Australian startup sets a launch date. The first attempt to send an Australian-made rocket into orbit is set to take place no sooner than March 15, the Australian Broadcasting Corporation reports. Gilmour Space Technologies’ launch window announcement marks a major development for the company, which has been working towards a test launch for a decade. Gilmour previously hoped to launch its test rocket, Eris, in May 2024, but had to wait for the Australian government to issue a launch license and airspace approvals for the flight to go forward. Those are now in hand, clearing the last regulatory hurdle before liftoff.

Setting expectations … Gilmour’s Eris rocket is made of three stages powered by hybrid engines consuming a solid fuel and a liquid oxidizer. Eris is designed to haul payloads of up to 672 pounds (305 kilograms) to low-Earth orbit, and will launch from Bowen Orbital Spaceport in Queensland on Australia’s northeastern coast. Gilmour said it would be “very lucky” if the rocket reached orbit on first attempt. “Success means different things for different people, but ignition and liftoff will be huge,” said James Gilmour, the company’s co-founder.

Blue Origin is keeping a secret. Blue Origin conducted the tenth crewed flight of its New Shepard suborbital vehicle Tuesday, carrying six people, one of whom remained at least semi-anonymous, Space News reports. The five passengers Blue Origin identified come from business and entertainment backgrounds, but in a break from past missions, the company did not disclose the identity of the sixth person, with hosts of the company webcast saying that individual “requested we not share his name today.” Photos released by the company before the launch, and footage from the webcast, showed that person to be a man wearing a flight suit with an “R. Wilson” nametag, and the NS-30 mission patch also included “Wilson” with the names of the other members of the crew. Not disclosing the name of someone who has been to space has little precedent.

Big names on NS-31 … Some of the passengers Blue Origin will fly on the next New Shepard crew mission lack the anonymity of R. Wilson. The next flight, designated NS-31, will carry an all-female crew, including music star Katy Perry, CBS host Gayle King, and Lauren Sánchez, a former journalist who is engaged to Blue Origin’s founder, Jeff Bezos. Blue Origin identified the other three passengers as Aisha Bowe, Amanda Ngyuen, and Kerianne Flynn. (submitted by EllPeaTea)

Virgin Galactic is still blowing through cash. Virgin Galactic reported a net loss of $347 million in 2024, compared to a $502 million net loss in 2023, with the improvement primarily driven by lower operating expenses, the company said this week in a quarterly earnings release. These lower operating expenses are tied to Virgin Galactic’s decision to suspend operations of its VSS Unity suborbital rocket plane last year to focus investment into a new series of suborbital spacecraft known as Delta-class ships. Virgin Galactic said cash and cash equivalents fell 18 percent from the same period a year ago to $178.6 million. Investors have been eager for details on when it would resume—and then ramp up—flights to increase sales and cash in on a backlog of around 700 ticket holders, Bloomberg reports.

March toward manufacturing … Virgin Galactic said it plans to start assembling its first Delta-class ship in March, with a first flight targeted for the summer of 2026, two years after it stopped flying VSS Unity. The Delta ships will be easier to recycle between flights, and will carry six paying passengers, rather than the four VSS Unity carried on each flight. Company officials believe a higher flight rate with more passengers will bring in significantly more revenue, which was reported at just $430,000 in the fourth quarter of 2024.

Japanese customers seem to love Rocket Lab. While Rocket Lab is developing the larger Neutron rocket, the company’s operational Electron launch vehicle continues to dominate the market for dedicated launches of small satellites. Rocket Lab announced Thursday it signed a new multi-launch deal with iQPS, a Japan-based Earth imaging company. The new deal follows an earlier multi-launch contract signed with iQPS in 2024 and brings the total number of booked dedicated Electron launches for iQPS to eight.

Radar is all the rage … These eight Electron launches in 2025 and 2026 will help iQPS build out its planned constellation of 36 radar remote sensing satellites capable of imaging the Earth day and night, and through any weather. The new deal is one of the largest Electron launch agreements to date, second only to Rocket Lab’s ten launch deal with another Japanese radar constellation operator, Synspective, signed last year.

Falcon 9 launch targets Moon and asteroid. With two commercial Moon landers already on their way, Houston-based Intuitive Machines launched its second robotic lander atop a SpaceX Falcon 9 rocket Wednesday, CBS News reports. Given the on-time launch and assuming no major problems, the Athena lander is expected to descend to touchdown on a flat mesa-like structure known as Mons Mouton on March 6, setting down just 100 miles from the Moon’s south pole—closer than any other spacecraft has attempted. Intuitive Machines became the first company to successfully land a spacecraft on the Moon last year, but the Athena lander will pursue more complex goals. It will test a NASA-provided drill designed to search for subsurface ice, deploy a small “micro-rover,” and dispatch a rocket-powered drone to explore a permanently shadowed crater.

Hitching a ride … The Athena lander didn’t take up all the capacity of the Falcon 9 rocket. Three other spacecraft also rocketed into space Wednesday night. These rideshare payloads were AstroForge’s commercially developed Odin asteroid prospector to search for potentially valuable mineral deposits, NASA’s Lunar Trailblazer satellite to characterize lunar ice from a perch in lunar orbit, and a compact space tug from Epic Aerospace.

This rocket got a visitor for the first time since 2009. Astroscale’s ADRAS-J mission became the first spacecraft (at least in the unclassified world) to approach a piece of space junk in low-Earth orbit, Ars reports. This particular object, a derelict upper stage from a Japanese H-IIA rocket, has been in orbit since 2009. It’s one of about 2,000 spent rocket bodies circling the Earth and one of more than 45,000 objects in orbit tracked by US Space Command. Astroscale, based in Tokyo, built and launched the ADRAS-J mission in partnership with the Japanese space agency as a demonstration to show how a commercial satellite could rendezvous with an object in orbit that was never designed to receive visitors.

Next steps … ADRAS-J worked like a champ, closing in to a distance of less than 50 feet (15 meters) from the H-IIA rocket as it orbited several hundred miles above the Earth. The rocket is a “non-cooperative” object representative of other large pieces of space junk, which Astroscale wants to remove from orbit with a series of trash collecting satellites like ADRAS-J. But this demo only validated part of the technology required for space debris removal. Japan’s space agency and Astroscale are partnering on another mission, ADRAS-J2, for launch in 2027 to go up and latch on to the same H-IIA rocket and steer it out of orbit toward a controlled reentry over the ocean.

An update on Falcon 9’s upper stage. SpaceX said that a Falcon 9 upper stage that reentered over Europe earlier this month suffered a propellant leak that prevented it from doing a controlled reentry, Space News reports. The upper stage was placed in orbit on a February 1 launch from Vandenberg Space Force Base in California. After deploying its payload of 22 Starlink satellites, the upper stage was expected to perform a burn to enable a controlled reentry over the ocean, a standard procedure on most Falcon 9 launches to low-Earth orbit. The stage, though, did not appear to perform the burn and remained in orbit. Its orbit decayed from atmospheric drag and the stage reentered over Europe on February 19. Debris from the Falcon 9 second stage, including composite overwrapped pressure vessels, fell in Poland, landing near the city of Poznań.

Higher than expected body rates … In an update posted to its website this week, SpaceX blamed the upper stage anomaly on a liquid oxygen leak. “During the coast phase of this Starlink mission, a small liquid oxygen leak developed, which ultimately drove higher than expected vehicle body rates,” SpaceX said. SpaceX aborted the deorbit burn and instead passivated the upper stage, a process where the rocket discharges energy from its batteries and vents leftover propellant from its tanks to minimize the risk of a break-up in orbit. This was the third incident involving a Falcon 9 upper stage in a little more than six months. (submitted by EllPeaTea)

Rocket Lab’s reveals “Return On Investment.” Rocket Lab’s Neutron rocket is designed for partial reusability, and the company unveiled Thursday an important piece of infrastructure to make this a reality. Neutron’s first stage booster will land on a modified barge named “Return On Investment” measuring around 400 feet (122 meters) wide, somewhat bigger than SpaceX’s drone ships used for Falcon 9 landings at sea. In order to prep the barge for rocket duty, the company is adding autonomous ground support equipment to capture and secure the landed Neutron, blast shielding to protect equipment during Neutron landings, and station-keeping thrusters for precise positioning. It should be ready to enter service in 2026. Rocket Lab also has the option to return the Neutron first stage back to the launch site when mission parameters allow the rocket to reserve enough propellant to make the return journey.

More news from Rocket Lab … Continuing the firehose of news from Rocket Lab this week, the company announced a new satellite design called “Flatellite” that looks remarkably similar to SpaceX’s Starlink satellites. The satellite is flat in shape, hence its name, and stackable to fit as many spacecraft as possible into the envelope of a rocket’s payload fairing. Rocket Lab said the new satellite “can be produced in high volumes and (is) tailored for large constellations, targeting high value applications and national security missions.” (submitted by zapman987)

The writing is on the wall for SLS. The lights may be starting to go out for NASA’s Space Launch System program. On Wednesday, one of the Republican space policy leaders most consistently opposed to commercial heavy lift rockets over the last decade—as an alternative to NASA’s large SLS rocket—has changed his mind, Ars reports. “We need an off-ramp for reliance on the SLS,” said Scott Pace, director of the Space Policy Institute at George Washington University, in written testimony before a congressional hearing about US space policy.

Not keeping Pace … A physicist and influential policy expert, Pace has decades of experience researching and writing space policy. He has served in multiple Republican administrations, most recently as executive secretary of the National Space Council from 2017 to 2020. He strongly advocated for the SLS rocket after Congress directed NASA to develop it in 2011. As part of his policy recommendations, Pace said NASA should seek to use commercial providers of heavy lift launch so that NASA can send “multiple” crew and cargo missions to the Moon each year. He notes that the SLS rocket is not reusable and is incapable of a high flight rate. Commercial options from SpaceX, Blue Origin, and United Launch Alliance are now available, Pace wrote.

The verdict is in for Starship Flight 7. SpaceX believes the spectacular break-up of Starship’s upper stage during its most recent test flight was caused by a harmonic response that stressed onboard hardware, leading to a fire and loss of the vehicle, Aviation Week reports. Higher-than-expected vibrations stressed hardware in the ship’s propulsion system, triggering propellant leaks and sustained fires until the test flight ended prematurely. The rocket broke apart and deposited debris over the Turks and Caicos Islands and the Atlantic Ocean, and forced dozens of commercial and private aircraft to delay their flights or steer into safer airspace.

Whole lotta shaking … SpaceX’s description of the problem as a harmonic response suggests vibrations during Starship’s climb into space were in resonance with the vehicle’s natural frequency. This would have intensified the vibrations beyond the levels engineers expected from ground testing. SpaceX completed an extended duration static fire of the next Starship upper stage to test hardware modifications at multiple engine thrust levels. According to SpaceX, findings from the static fire informed changes to the fuel feed lines to Starship’s Raptor engines, adjustments to propellant temperatures, and a new operating thrust for the next test flight, which could launch from South Texas as soon as Monday.

Welcome to Edition 7.31 of the Rocket Report! The unfortunate news this week concerns layoffs. Blue Origin announced a 10 percent cut in its workforce as the company aims to get closer to breaking even. More broadly in the space industry, there is unease about what the Trump administration’s cuts to NASA and other federal agencies might mean.

We don’t have all the answers, but it does seem that NASA is likely to be subject to less deep cuts than some other parts of the government. We should find out sometime in March when the Trump White House submits its initial budget request. Congress, of course, will have the final say.

Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

PLD Space continues to grow. The Spain-based launch company said this week that it now has more than 300 employees as it works toward an orbital launch attempt. “In this race for space supremacy, the amount of capital raised and the talent gathered have become key indicators of a company’s potential for success,” the company said. “While capital acts as the fuel for these ambitious initiatives, the talent behind it is the catalyst that drives them.”

Working to reach orbit … The average age of employees at PLD Space is 34, and the company is hiring 15 people a month as it works to develop the Miura 5 rocket. It’s unclear which of the commercial launch startups in Europe will succeed, but PLD Space has a decent chance to be among them. With luck, the Miura 5 launch vehicle will make its debut sometime in 2026.

Will NASA launch on a Transporter mission? NASA announced this week that it has selected SpaceX to launch a small exoplanet science mission as a rideshare payload as soon as September, Space News reports. The task order to launch the Pandora mission was made through the Venture-class Acquisition of Dedicated and Rideshare launch services contract, intended for small missions with higher acceptance of risk.

Could fly on a Falcon 9 … Pandora is an ESPA Grande-class spacecraft, a category that includes spacecraft weighing up to 320 kilograms, and is designed to operate in a Sun-synchronous orbit. That suggests Pandora could launch on SpaceX’s Transporter series of dedicated rideshare missions that send payloads to such orbits, but neither NASA nor SpaceX disclosed specifics. The NASA announcement also did not disclose the value of the task order to SpaceX.

Stoke Space dishes on Andromeda upper stage. The Washington-based launch company has revealed the name of its Nova rocket’s upper stage, Andromeda, and provided some new details about the design. Andromeda will incorporate hot staging, Stoke says, and will use fewer but larger thrusters—24 instead of 30. The upper stage is now mounted on Stoke’s test stand in Moses Lake, Washington, the company said.

Hot staging, hot talk … The new design is focused on rapid reusability, with easier access and serviceability to components of the engines and heat shield. “These changes further reduce complexity and allow the entire engine to be serviced—or even replaced—within hours or minutes. Rapid turnaround isn’t merely a goal, it’s baked into the design,” the company said. The upper stage will also incorporate “hot staging” to improve the capacity to orbit. You’ve got to appreciate the subtle dig at SpaceX’s Starship program, too: the design allows for hot staging “without the need for a heavy one-time-use interstage shield to protect Stage 1.” Shots fired!

European space commissioner worried about launch. During a keynote address at the Perspectives Spatiales 2025 event in Paris, European Commissioner for Defence Industry and Space Andrius Kubilius outlined the challenging position the continent’s space sector finds itself in, European Spaceflight reports. “Commercial sales are down. Exports are down. Profits are down. And this comes at a time when we need space more than ever. For our security. For our survival.”

Actions, not words, needed … Rhetorical language and bold declarations are inspiring, but when it comes to securing Europe’s place in the global space race, adopted policy and appropriated funding are where aspirations are tested, the European publication stated. Without concrete investments, streamlined regulations, and clear strategic priorities, Europe’s ambition to once again lead the global launch market is likely to amount to little.

Election set to create Starbase, the city. A Texas county on Wednesday approved holding an election sought by SpaceX that would let residents living around the company’s launch and production facilities in South Texas decide whether to formally create a new city called Starbase, ABC News reports. The election was set for May 3, and votes can only be cast by residents living near the launch site, which is currently part of an unincorporated area of Cameron County located along the US-Mexico border. Approval is expected.

A busy beehive … In December, more than 70 area residents signed a petition requesting an election to make Starbase its own municipality. Cameron County Judge Eddie Treviño said the county reviewed the petition and found it met the state’s requirements for the incorporation process to move forward. Kathy Lueders, Starbase’s general manager, has previously said that the incorporation would streamline certain processes to build amenities in the area. More than 3,400 full-time SpaceX employees and contractors work at the site. (submitted by teb)

China taps into commercial space for station missions. China will launch a pair of low-cost space station resupply spacecraft this year on new commercial launch vehicles, Space News reports. The Haolong cargo space shuttle from the Chengdu Aircraft Design Institute will launch on Landspace’s Zhuque-3. The reusable stainless steel, methane-liquid oxygen Zhuque-3 rocket is due to have its first flight in the third quarter of this year. The reusable Haolong vehicle will be 10 meters in length, around 7,000 kilograms in mass, and capable of landing on a runway.

Following a commercial trail laid by NASA … Meanwhile, the Qingzhou cargo spacecraft from the Innovation Academy for Microsatellites of the Chinese Academy of Sciences will launch on the first flight of the CAS Space Kinetica-2 (Lijian-2) rocket no earlier than September. The development is analogous to NASA’s Commercial Resupply Services program, diversifying China’s options for supplying the Tiangong space station. If even one of these missions takes place successfully within the next year, it would represent a major step forward for China’s quasi-commercial space program. (submitted by EllPeaTea)

H3 rocket launches its fifth mission. Japan’s flagship H3 rocket successfully launched the Michibiki 6 navigation satellite early Sunday, enhancing the country’s regional GPS capabilities, Space News reports. The launch was Japan’s first of 2025 and suggests that the relatively new H3 rocket is starting to hit its stride.

Getting up to speed … The expendable launcher’s inaugural launch in March 2023, after numerous delays, suffered a second-stage engine failure, leading controllers to issue a destruct command to destroy the stage and its ALOS-3 payload. Since then, it has had a successful run of launches, most recently the Kirameki 3 communications satellite for defense purposes in November last year. (submitted by EllPeaTea)

Blue Origin lays off 10 percent of its employees. A little less than a month after the successful debut of its New Glenn rocket, Blue Origin’s workforce will be trimmed by 10 percent, Ars reports. The cuts were announced during an all-hands meeting on Thursday morning led by the rocket company’s chief executive, Dave Limp. During the gathering, Limp cited business strategy as the rationale for making the cuts to a workforce of more than 10,000 people.

Growing too fast … “We grew and hired incredibly fast in the last few years, and with that growth came more bureaucracy and less focus than we needed,” Limp wrote in an email to the entire workforce after the meeting. Even before Thursday’s announcement, Blue Origin sought to control costs. According to sources, the company has had a hiring freeze for the last six months. And in January, it let the majority of its contractors go. Layoffs suck—here’s hoping that those let go this week find a soft landing.

Speaking of Blue, they’re targeting spring for next launch. Blue Origin expects to attempt its second New Glenn launch in late spring after correcting problems that prevented the booster from landing on the first launch last month, Space News reports. Speaking at the 27th Annual Commercial Space Conference on Wednesday, Dave Limp suggested a propulsion issue caused the loss of the New Glenn booster during its landing attempt on the Jan. 16 NG-1 launch.

Understanding the issues … “We had most of the right conditions in the engine but we weren’t able to get everything right to the engine from the tanks,” Limp said. “We think we understand what the issues are.” A second booster is in production. “I don’t think it’s going to delay our path to flight,” Limp said of the investigation. “I think we can still fly late spring.” June seems overly optimistic. One source with knowledge of the second booster’s production said October might be a more reasonable timeframe for the second launch.

Boeing warns of potential SLS workforce cuts. The primary contractor for the Space Launch System rocket, Boeing, is preparing for the possibility that NASA cancels the long-running program, Ars reports. Last Friday, with less than an hour’s notice, David Dutcher, Boeing’s vice president and program manager for the SLS rocket, scheduled an all-hands meeting for the approximately 800 employees working on the program. The apparently scripted meeting lasted just six minutes, and Dutcher didn’t take questions. Afterward, Ars learned that NASA was not informed the meeting would take place.

Waiting on the president’s budget request … During his remarks, Dutcher said Boeing’s contracts for the rocket could end in March and that the company was preparing for layoffs in case the contracts with the space agency were not renewed. The aerospace company, which is the primary contractor for the rocket’s large core stage, issued the notifications as part of the Worker Adjustment and Retraining Notification (or WARN) Act. The timing of Friday’s hastily called meeting aligns with the anticipated release of President Trump’s budget proposal for fiscal year 2026, which should signal the administration’s direction on the SLS rocket.

Space Force is still waiting on Vulcan. Last October, United Launch Alliance started stacking its third Vulcan rocket on a mobile launch platform in Florida in preparation for a mission for the US Space Force by the end of the year. However, that didn’t happen, Ars reports. Now, ULA is still awaiting the Space Force’s formal certification of its new rocket, further pushing out delivery schedules for numerous military satellites booked to fly to orbit on the Vulcan launcher.

Falling short of ambitious goals … In fact, ULA has started to take the rocket apart. This involves removing the rocket’s Centaur upper stage, interstage adapter, and booster stage from its launch mount. Instead, ULA will now focus on launching a batch of Project Kuiper satellites for Amazon on an Atlas V rocket in the next couple of months before pivoting back to Vulcan. ULA hoped to launch as many as 20 missions in 2025, with roughly an even split between its new Vulcan rocket and the Atlas V heading for retirement. Clearly, this now won’t happen.
