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 Weapon—also 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.

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). 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.

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.

A military satellite waiting to launch with ULA will now fly with SpaceX

falcon 9, GPS, launch, military space, Space, spacex, united launch alliance, vulcan / Mike M. / April 8, 2025

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.

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 Space Force booked the Vulcan rocket to launch this spacecraft in 2023, when ULA hoped to begin flying military satellites on its new rocket by mid-2024. The Vulcan rocket is now scheduled to launch its first national security mission around the middle of this year, following the Space Force’s certification of ULA’s new launcher last month.

The “launch vehicle trade” allows the Space Force to launch the GPS III SV-08 satellite from Cape Canaveral, Florida, as soon as the end of May, according to a press release.

“Capability sitting on the ground”

With Vulcan now cleared to launch military missions, officials are hopeful ULA can ramp up the rocket’s flight cadence. Vulcan launched on two demonstration flights last year, and ULA eventually wants to launch Vulcan twice per month. ULA engineers have their work cut out for them. The company’s Vulcan backlog now stands at 89 missions, following the Space Force’s announcement last week of 19 additional launches awarded to ULA.

Last year, the Pentagon’s chief acquisition official for space wrote a letter to ULA’s owners—Boeing and Lockheed Martin—expressing concern about ULA’s ability to scale the manufacturing of the Vulcan rocket.

“Currently there is military satellite capability sitting on the ground due to Vulcan delays,” Frank Calvelli, the Pentagon’s chief of space acquisition, wrote in the letter.

Vulcan may finally be on the cusp of delivering for the Space Force, but there are several military payloads in the queue to launch on Vulcan before GPS III SV-08, which was complete and in storage at its Lockheed Martin factory in Colorado.

Col. Jim Horne, senior materiel leader of launch execution, said in a statement that the rocket swap showcases the Space Force’s ability to launch in three months from call-up, compared to the typical planning cycle of two years. “It highlights another instance of the Space Force’s ability to complete high-priority launches on a rapid timescale, which demonstrates the capability to respond to emergent constellation needs as rapidly as Space Vehicle readiness allows,” Horne said.

With new contracts, SpaceX will become the US military’s top launch provider

The US Space Force announced Friday it selected SpaceX, United Launch Alliance, and Blue Origin for $13.7 billion in contracts to deliver the Pentagon’s most critical military to orbit into the early 2030s.

These missions will launch the government’s heaviest national security satellites, like the National Reconnaissance Office’s large bus-sized spy platforms, and deploy them into bespoke orbits. These types of launches often demand heavy-lift rockets with long-duration upper stages that can cruise through space for six or more hours.

The contracts awarded Friday are part of the next phase of the military’s space launch program once dominated by United Launch Alliance, the 50-50 joint venture between legacy defense contractors Boeing and Lockheed Martin.

After racking up a series of successful launches with its Falcon 9 rocket more than a decade ago, SpaceX sued the Air Force for the right to compete with ULA for the military’s most lucrative launch contracts. The Air Force relented in 2015 and allowed SpaceX to bid. Since then, SpaceX has won more than 40 percent of missions the Pentagon has ordered through the National Security Space Launch (NSSL) program, creating a relatively stable duopoly for the military’s launch needs.

The Space Force took over the responsibility for launch procurement from the Air Force after its creation in 2019. The next year, the Space Force signed another set of contracts with ULA and SpaceX for missions the military would order from 2020 through 2024. ULA’s new Vulcan rocket initially won 60 percent of these missions—known as NSSL Phase 2—but the Space Force reallocated a handful of launches to SpaceX after ULA encountered delays with Vulcan.

ULA’s Vulcan and SpaceX’s Falcon 9 and Falcon Heavy rockets will launch the remaining 42 Phase 2 missions over the next several years, then move on to Phase 3, which the Space Force announced Friday.

Spreading the wealth

This next round of Space Force launch contracts will flip the script, with SpaceX taking the lion’s share of the missions. The breakdown of the military’s new firm fixed-price launch agreements goes like this:

SpaceX will get 28 missions worth approximately $5.9 billion
ULA will get 19 missions worth approximately $5.4 billion
Blue Origin will get seven missions worth approximately

That equates to a 60-40 split between SpaceX and ULA for the bulk of the missions. Going into the competition, military officials set aside seven additional missions to launch with a third provider, allowing a new player to gain a foothold in the market. The Space Force reserves the right to reapportion missions between the three providers if one of them runs into trouble.

The Pentagon confirmed an unnamed fourth company also submitted a proposal, but wasn’t selected for Phase 3.

Rounded to the nearest million, the contract with SpaceX averages out to $212 million per launch. For ULA, it’s $282 million, and Blue Origin’s price is $341 million per launch. But take these numbers with caution. The contracts include a lot of bells and whistles, pricing them higher than what a commercial customer might pay.

According to the Pentagon, the contracts provide “launch services, mission unique services, mission acceleration, quick reaction/anomaly resolution, special studies, launch service support, fleet surveillance, and early integration studies/mission analysis.”

Essentially, the Space Force is paying a premium to all three launch providers for schedule priority, tailored solutions, and access to data from every flight of each company’s rocket, among other things.

“Winning 60% percent of the missions may sound generous, but the reality is that all SpaceX competitors combined cannot currently deliver the other 40%!,” Elon Musk, SpaceX’s founder and CEO, posted on X. “I hope they succeed, but they aren’t there yet.”

This is true if you look at each company’s flight rate. SpaceX has launched Falcon 9 and Falcon Heavy rockets 140 times over the last 365 days. These are the flight-proven rockets SpaceX will use for its share of Space Force missions.

ULA has logged four missions in the same period, but just one with the Vulcan rocket it will use for future Space Force launches. And Blue Origin, Jeff Bezos’s space company, launched the heavy-lift New Glenn rocket on its first test flight in January.

“We are proud that we have launched 100 national security space missions and honored to continue serving the nation with our new Vulcan rocket,” said Tory Bruno, ULA’s president and CEO, in a statement.

ULA used the Delta IV and Atlas V rockets for most of the missions it has launched for the Pentagon. The Delta IV rocket family is now retired, and ULA will end production of the Atlas V rocket later this year. Now, ULA’s Vulcan rocket will take over as the company’s sole launch vehicle to serve the Pentagon. ULA aims to eventually ramp up the Vulcan launch cadence to fly up to 25 times per year.

After two successful test flights, the Space Force formally certified the Vulcan rocket last week, clearing the way for ULA to start using it for military missions in the coming months. While SpaceX has a clear advantage in number of launches, schedule assurance, and pricing—and reliability comparable to ULA—Bruno has recently touted the Vulcan rocket’s ability to maneuver over long periods in space as a differentiator.

“This award constitutes the most complex missions required for national security space,” Bruno said in a ULA press release. “Vulcan continues to use the world’s highest energy upper stage: the Centaur V. Centaur V’s unmatched flexibility and extreme endurance enables the most complex orbital insertions continuing to advance our nation’s capabilities in space.”

Blue Origin’s New Glenn must fly at least one more successful mission before the Space Force will certify it for Lane 2 missions. The selection of Blue Origin on Friday suggests military officials believe New Glenn is on track for certification by late 2026.

“Honored to serve additional national security missions in the coming years and contribute to our nation’s assured access to space,” Dave Limp, Blue Origin’s CEO, wrote on X. “This is a great endorsement of New Glenn’s capabilities, and we are committed to meeting the heavy lift needs of our US DoD and intelligence agency customers.”

Navigating NSSL

There’s something you must understand about the way the military buys launch services. For this round of competition, the Space Force divided the NSSL program into two lanes.

Friday’s announcement covers Lane 2 for traditional military satellites that operate thousands of miles above the Earth. This bucket includes things like GPS navigation satellites, NRO surveillance and eavesdropping platforms, and strategic communications satellites built to survive a nuclear war. The Space Force has a low tolerance for failure with these missions. Therefore, the military requires rockets be certified before they can launch big-ticket satellites, each of which often cost hundreds of millions, and sometimes billions, of dollars.

The Space Force required all Lane 2 bidders to show their rockets could reach nine “reference orbits” with payloads of a specified mass. Some of the orbits are difficult to reach, requiring technology that only SpaceX and ULA have demonstrated in the United States. Blue Origin plans to do so on a future flight.

The higher orbits will require launches by “Lane 2” providers. Credit: Space Systems Command

The military projects to order 54 launches in Lane 2 from this year through 2029, with announcements each October of exactly which missions will go to each launch provider. This year, it will be just SpaceX and ULA. The Space Force said Blue Origin won’t be eligible for firm orders until next year. The missions would launch between 2027 and 2032.

“America leads the world in space launch, and through these NSSL Phase 3 Lane 2 contracts, we will ensure continued access to this vital domain,” said Maj. Gen. Stephen Purdy, Acting Assistant Secretary of the Air Force for Space Acquisition and Integration. “These awards bolster our ability to launch critical defense satellites while strengthening our industrial base and enhancing operational readiness.”

Lane 1 is primarily for missions to low-Earth orbit. These payloads include tech demos, experimental missions, and the military’s mega-constellation of missile tracking and data relay satellites managed by the Space Development Agency. For Lane 1 missions, the Space Force won’t levy the burdensome certification and oversight requirements it has long employed for national security launches. The Pentagon is willing to accept more risk with Lane 1, encompassing at least 30 missions through the end of the 2020s, in an effort to broaden the military’s portfolio of launch providers and boost competition.

Last June, Space Systems Command chose SpaceX, ULA, and Blue Origin for eligibility to compete for Lane 1 missions. SpaceX won all nine of the first batch of Lane 1 missions put up for bids. The military recently added Rocket Lab’s Neutron rocket and Stoke Space’s Nova rocket to the Lane 1 mix. Neither of those rockets have flown, and they will need at least one successful launch before approval to fly military payloads.

The Space Force has separate contract mechanisms for the military’s smallest satellites, which typically launch on SpaceX rideshare missions or dedicated launches with companies like Rocket Lab and Firefly Aerospace.

Military leaders like having all these options, and would like even more. If one launch provider or launch site is unavailable due to a technical problem—or, as some military officials now worry, an enemy attack—commanders want multiple backups in their toolkit. Market forces dictate that more competition should also lower prices.

“A robust and resilient space launch architecture is the foundation of both our economic prosperity and our national security,” said US Space Force Chief of Space Operations Gen. Chance Saltzman. “National Security Space Launch isn’t just a program; it’s a strategic necessity that delivers the critical space capabilities our warfighters depend on to fight and win.”

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.

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 7.35 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.

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).

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 7.33 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.

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.

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 7.30 of the Rocket Report! The US government relies on SpaceX for a lot of missions. These include launching national security satellites, putting astronauts on the Moon, and global broadband communications. But there are hurdles—technical and, increasingly, political—on the road ahead. To put it generously, Elon Musk, without whom much of what SpaceX does wouldn’t be possible, is one of the most divisive figures in American life today.

Now, a Democratic lawmaker in Congress has introduced a bill that would end federal contracts for special government employees (like Musk), citing conflict-of-interest concerns. The bill will go nowhere with Republicans in control of Congress, but it is enough to make me pause and think. When the Trump era passes and a new administration takes the White House, how will they view Musk? Will there be an appetite to reduce the government’s reliance on SpaceX? To answer this question, you must first ask if the government will even have a choice. What if, as is the case in many areas today, there’s no viable replacement for the services offered by SpaceX?

Blue Origin flight focuses on lunar research. For the first time, Jeff Bezos’ Blue Origin space venture has put its New Shepard suborbital rocket ship through a couple of minutes’ worth of Moon-level gravity, GeekWire reports. The uncrewed mission, known as NS-29, sent 30 research payloads on a 10-minute trip from Blue Origin’s Launch Site One in West Texas. For this trip, the crew capsule was spun up to 11 revolutions per minute, as opposed to the typical half-revolution per minute. The resulting centrifugal force was equivalent to one-sixth of Earth’s gravity, which is what would be felt on the Moon.

Gee, that’s cool … The experiments aboard Blue Origin’s space capsule examined how to process lunar soil to extract resources and how to manufacture solar cells on the Moon for Blue Origin’s Blue Alchemist project. Another investigated how moondust gets electrically charged and levitated when exposed to ultraviolet light. These types of experiments in partial gravity can be done on parabolic airplane flights, but those only provide a few seconds of the right conditions to simulate the Moon’s gravity.

Orbex announces two-launch deal with D-Orbit. UK-based rocket builder Orbex announced Monday that it has signed a two-launch deal with Italian in-orbit logistics provider D-Orbit, European Spaceflight reports. The deal includes capacity aboard two launches on Orbex’s Prime rocket over the next three years. D-Orbit aggregates small payloads on rideshare missions (primarily on SpaceX rockets so far) and has an orbital transfer vehicle for ferrying satellites to different altitudes after separation from a launch vehicle. Orbex’s Prime rocket is sized for the small satellite industry, and the company aims to debut it later this year.

Thanks to fresh funding? … Orbex has provided only sparse updates on its progress toward launching the Prime rocket. What we do know is that Orbex suspended plans to develop a spaceport in Scotland to focus its resources on the Prime rocket itself. Despite little evidence of any significant accomplishments, Orbex last month secured a $25 million investment from the UK government. The timing of the launch agreement with D-Orbit begs the question of whether the UK government’s backing helped seal the deal. As Andrew Parsonson of European Spaceflight writes: “Is this a clear indication of how important strong institutional backing is for the growth of privately developed launch systems in Europe?” (submitted by EllPeaTea)

Falcon 9’s upper stage misfires again. The second stage of a SpaceX Falcon 9 rocket remained in orbit following a launch Saturday from Vandenberg Space Force Base, California. The rocket successfully deployed a new batch of Starlink Internet satellites but was supposed to reignite its engine for a braking maneuver to head for a destructive reentry over the Pacific Ocean. While airspace warning notices from the FAA showed a reentry zone over the eastern Pacific Ocean, publicly available US military tracking continued to show the upper stage in orbit this week. Sources also told Ars that SpaceX delayed two Falcon 9 launches this week by a day to allow time for engineers to evaluate the problem.

3 in 6 months … This is the third time since last July that the Falcon 9’s upper stage has encountered a problem in flight. On one occasion, the upper stage failed to reach its targeted orbit, leading to the destruction of 20 Starlink satellites. Then, an upper stage misfired during a deorbit burn after an otherwise successful launch in September, causing debris to fall outside of the pre-approved danger area. After both events, the FAA briefly grounded the Falcon 9 rocket while SpaceX conducted an investigation. This time, an FAA spokesperson said the agency won’t require an investigation. “All flight events occurred within the scope of SpaceX’s licensed activities,” the spokesperson told Ars.

Vast tests hardware for commercial space station. Vast Space has started testing a qualification model of its first commercial space station but has pushed back the launch of that station into 2026, Space News reports. In an announcement Thursday, Vast said it completed a proof test of the primary structure of a test version of its Haven-1 space station habitat at a facility in Mojave, California. During the testing, Vast pumped up the pressure inside the structure to 1.8 times its normal level and conducted a leak test. “On the first try we passed that critical test,” Max Haot, chief executive of Vast, told Space News.

Not this year … It’s encouraging to see Vast making tangible progress in developing its commercial space station. The privately held company is one of several seeking to develop a commercial outpost in low-Earth orbit to replace the International Space Station after its scheduled retirement in 2030. NASA is providing funding to two industrial teams led by Blue Origin and Voyager Space, which are working on different space station concepts. But so far, Vast’s work has been funded primarily through private capital. The launch of the Haven-1 outpost, which Vast previously said could happen this year, is now scheduled no earlier than May 2026. The spacecraft will launch in one piece on a Falcon 9 rocket, and the first astronaut crew to visit Haven-1 could launch a month later. Haven-1 is a pathfinder for a larger commercial station called Haven-2, which Vast intends to propose to NASA. (submitted by EllPeaTea)

H3 deploys Japanese navigation satellite. Japan successfully launched a flagship H3 rocket Sunday and put into orbit a Quasi-Zenith Satellite (QZS), aiming to improve the accuracy of global positioning data for various applications, Kyodo News reports. After separation from the H3 rocket, the Michibiki 6 satellite will climb into geostationary orbit, where it will supplement navigation signals from GPS satellites to provide more accurate positioning data to users in Japan and surrounding regions, particularly in mountainous terrain and amid high-rise buildings in large cities. The new satellite joins a network of four QZS spacecraft launched by Japan beginning in 2010. Two more Quasi-Zenith Satellites are under construction, and Japan’s government is expected to begin development of an additional four regional navigation satellites this year.

A good start … After a failed inaugural flight in 2023, Japan’s new H3 rocket has reeled off four consecutive successful launches in less than a year. This may not sound like a lot, but the H3 has achieved its first four successful flights faster than any other rocket since 2000. SpaceX’s Falcon 9 rocket completed its first four successful flights in a little more than two years, and United Launch Alliance’s Atlas V logged its fourth flight in a similar timeframe. More than 14 months elapsed between the first and fourth successful flight of Rocket Lab’s Electron rocket. The H3 is an expendable rocket with no roadmap to reusability, so its service life and commercial potential are likely limited. But the rocket is shaping up to provide reliable access to space for Japan’s space agency and military, while some of its peers in Europe and the United States struggle to ramp up to a steady launch cadence.

Europe really doesn’t like relying on Elon Musk. Europe’s space industry has struggled to keep up with SpaceX for a decade. The writing was on the wall when SpaceX landed a Falcon 9 booster for the first time. Now, European officials are wary of becoming too reliant on SpaceX, and there’s broad agreement on the continent that Europe should have the capability to launch its own satellites. In this way, access to space is a strategic imperative for Europe. The problem is, Europe’s new Ariane 6 rocket is just not competitive with SpaceX’s Falcon 9, and there’s no concrete plan to counter SpaceX’s dominance.

So here’s another terrible idea … Airbus, Europe’s largest aerospace contractor with a 50 percent stake in the Ariane 6 program, has enlisted Goldman Sachs for advice on how to forge a new European space and satellite company to better compete with SpaceX. France-based Thales and the Italian company Leonardo are part of the talks, with Bank of America also advising on the initiative. The idea that some bankers from Goldman and Bank of America will go into the guts of some of Europe’s largest institutional space companies and emerge with a lean, competitive entity seems far-fetched, to put it mildly, Ars reports.

The FAA still has some bite. We’re now three weeks removed from the most recent test flight of SpaceX’s Starship rocket, which ended with the failure of the vehicle’s upper stage in the final moments of its launch sequence. The accident rained debris over the Atlantic Ocean and the Turks and Caicos Islands. Unsurprisingly, the Federal Aviation Administration grounded Starship and ordered an investigation into the accident on the day after the launch. This decision came three days before the inauguration of President Donald Trump, who counts Musk as one of his top allies. So far, the FAA hasn’t budged on its requirement for an investigation, an agency spokesperson told Ars.

Debris field … In the hours and days after the failed Starship launch, residents and tourists in the Turks and Caicos shared images of debris scattered across the islands and washing up onshore. The good news is there were no injuries or reports of significant damage from the wreckage, but the FAA confirmed one report of minor damage to a vehicle located in South Caicos. It’s rare for debris from US rockets to fall over land during a launch. This would typically only happen if a launch failed at certain parts of the flight. Before now, there has been no public record of any claims of third-party property damage in the era of commercial spaceflight.

DOD eager to reap the benefits of Starship. A Defense Department unit is examining how SpaceX’s Starship vehicle could be used to support a broader architecture of in-space refueling, Space News reports. A senior adviser at the Defense Innovation Unit (DIU) said SpaceX approached the agency about how Starship’s refueling architecture could be used by the wider space industry. The plan for Starship is to transfer cryogenic propellants between tankers, depots, and ships heading to the Moon, Mars, or other deep-space destinations.

Few details available … US military officials have expressed interest in orbital refueling to support in-space mobility, where ground controllers have the freedom to maneuver national security satellites between different orbits without worrying about running out of propellant. For several years, Space Force commanders and Pentagon officials have touted the importance of in-space mobility, or dynamic space operations, in a new era of orbital warfare. However, there are reports that the Space Force has considered zeroing out a budget line item for space mobility in its upcoming fiscal year 2026 budget request.

A small step toward a fully reusable European rocket. The French space agency CNES has issued a call for proposals to develop a reusable upper stage for a heavy-lift rocket, European Spaceflight reports. This project is named DEMESURE (DEMonstration Étage SUpérieur REutilisable / Reusable Upper Stage Demonstration), and it marks one of Europe’s first steps in developing a fully reusable rocket. That’s all good, but there’s a sense of tentativeness in this announcement. The current call for proposals will only cover the earliest phases of development, such as a requirements evaluation, cost estimation review, and a feasibility meeting. A future call will deal with the design and fabrication of a “reduced scale” upper stage, followed by a demonstration phase with a test flight, recovery, and reuse of the vehicle. CNES’s vision is to field a fully reusable rocket as a successor to the single-use Ariane 6.

Toes in the water … If you’re looking for reasons to be skeptical about Project DEMESURE, look no further than the Themis program, which aims to demonstrate the recovery and reuse of a booster stage akin to SpaceX’s Falcon 9. Themis originated in a partnership between CNES and European industry in 2019, then ESA took over the project in 2020. Five years later, the Themis demonstrator still hasn’t flown. After some initial low-altitude hops, Themis is supposed to launch on a high-altitude test flight and maneuver through the entire flight profile of a reusable booster, from liftoff to a vertical propulsive landing. As we’ve seen with SpaceX, recovering an orbital-class upper stage is a lot harder than landing the booster. An optimistic view of this announcement is that anything worth doing requires taking a first step, and that’s what CNES has done here. (submitted by EllPeaTea)

Two lunar landers are on the way to the Moon after SpaceX’s double moonshot

clps, Commercial space, falcon 9, Firefly Aerospace, ispace, Japan, launch, moon, NASA, Science, Space / Kelly Newman / January 16, 2025

Julianna Scheiman, director of NASA science missions for SpaceX, said it made sense to pair the Firefly and ispace missions on the same Falcon 9 rocket.

“When we have two missions that can each go to the Moon on the same launch, that is something that we obviously want to take advantage of,” Scheiman said. “So when we found a solution for the Firefly and ispace missions to fly together on the same Falcon 9, it was a no-brainer to put them together.”

SpaceX stacked the two landers, one on top of the other, inside the Falcon 9’s payload fairing. Firefly’s lander, the larger of the two spacecraft, rode on top of the stack and deployed from the rocket first. The Resilience lander from ispace launched in the lower position, cocooned inside a specially designed canister. Once Firefly’s lander separated from the Falcon 9, the rocket jettisoned the canister, performed a brief engine firing to maneuver into a slightly different orbit, then released ispace’s lander.

This dual launch arrangement resulted in a lower launch price for Firefly and ispace, according to Scheiman.

“At SpaceX, we are really interested in and invested in lowering the cost of launch for everybody,” she said. “So that’s something we’re really proud of.”

The Blue Ghost and Resilience landers will take different paths toward the Moon.

Firefly’s Blue Ghost will spend about 25 days in Earth orbit, then four days in transit to the Moon. After Blue Ghost enters lunar orbit, Firefly’s ground team will verify the readiness of the lander’s propulsion and navigation systems and execute several thruster burns to set up for landing.

Blue Ghost’s final descent to the Moon is tentatively scheduled for March 2. The target landing site is in Mare Crisium, an ancient 350-mile-wide (560-kilometer) impact basin in the northeast part of the near side of the Moon.

After touchdown, Blue Ghost will operate for about 14 days (one entire lunar day). The instruments aboard Firefly’s lander include a subsurface drill, an X-ray imager, and an experimental electrodynamic dust shield to test methods of repelling troublesome lunar dust from accumulating on sensitive spacecraft components.

The Resilience lander from ispace will take four to five months to reach the Moon. It carries several intriguing tech demo experiments, including a water electrolyzer provided by a Japanese company named Takasago Thermal Engineering. This demonstration will test equipment that future lunar missions could use to convert the Moon’s water ice resources into electricity and rocket fuel.

The lander will also deploy a “micro-rover” named Tenacious, developed by an ispace subsidiary in Luxembourg. The Tenacious rover will attempt to scoop up lunar soil and capture high-definition imagery of the Moon.

Ron Garan, CEO of ispace’s US-based subsidiary, told Ars that this mission is “pivotal” for the company.

“We were not fully successful on our first mission,” Garan said in an interview. “It was an amazing accomplishment, even though we didn’t have a soft landing… Although the hardware worked flawlessly, exactly as it was supposed to, we did have some lessons learned in the software department. The fixes to prevent what happened on the first mission from happening on the second mission were fairly straightforward, so that boosts our confidence.”

The ispace subsidiary led by Garan, a former NASA astronaut, is based in Colorado. While the Resilience lander launched Wednesday is not part of the CLPS program, the company will build an upgraded lander for a future CLPS mission for NASA, led by Draper Laboratory.

“I think the fact that we have two lunar landers on the same rocket for the first time in history is pretty substantial,” Garan said. I think we all are rooting for each other.”

Investors need to see more successes with commercial lunar landers to fully realize the market’s potential, Garan said.

“That market, right now, is very nascent. It’s very, very immature. And one of the reasons for that is that it’s very difficult for companies that are contemplating making investments on equipment, experiments, etc., to put on the lunar surface and lunar orbit,” Garan said. “It’s very difficult to make those investments, especially if they’re long-term investments, because there really hasn’t been a proof of concept yet.”

“So every time we have a success, that makes it more likely that these companies that will serve as the foundation of a commercial lunar market movement will be able to make those investments,” Garan said. “Conversely, every time we have a failure, the opposite happens.”

Welcome to Edition 7.19 of the Rocket Report! Okay, we get it. We received more submissions from our readers on Australia’s approval of a launch permit for Gilmour Space than we’ve received on any other news story in recent memory. Thank you for your submissions as global rocket activity continues apace. We’ll cover Gilmour in more detail as they get closer to launch. There will be no Rocket Report next week as Eric and I join the rest of the Ars team for our 2024 Technicon in New York.

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.

Gilmour Space has a permit to fly. Gilmour Space Technologies has been granted a permit to launch its 82-foot-tall (25-meter) orbital rocket from a spaceport in Queensland, Australia. The space company, founded in 2012, had initially planned to lift off in March but was unable to do so without approval from the Australian Space Agency, the Australian Broadcasting Corporation reports. The government approved Gilmour’s launch permit Monday, although the company is still weeks away from flying its three-stage Eris rocket.

A first for Australia … Australia hosted a handful of satellite launches with US and British rockets from 1967 through 1971, but Gilmour’s Eris rocket would become the first all-Australian launch vehicle to reach orbit. The Eris rocket is capable of delivering about 670 pounds (305 kilograms) of payload mass into a Sun-synchronous orbit. Eris will be powered by hybrid rocket engines burning a solid fuel mixed with a liquid oxidizer, making it unique among orbital-class rockets. Gilmour completed a wet dress rehearsal, or practice countdown, with the Eris rocket on the launch pad in Queensland in September. The launch permit becomes active after 30 days, or the first week of December. “We do think we’ve got a good chance of launching at the end of the 30-day period, and we’re going to give it a red hot go,” said Adam Gilmour, the company’s co-founder and CEO.

North Korea tests new missile. North Korea apparently completed a successful test of its most powerful intercontinental ballistic missile on October 31, lofting it nearly 4,800 miles (7,700 kilometers) into space before the projectile fell back to Earth, Ars reports. This solid-fueled, multi-stage missile, named the Hwasong-19, is a new tool in North Korea’s increasingly sophisticated arsenal of weapons. It has enough range—perhaps as much as 9,320 miles (15,000 kilometers), according to Japan’s government—to strike targets anywhere in the United States. It also happens to be one of the largest ICBMs in the world, rivaling the missiles fielded by the world’s more established nuclear powers.

Quid pro quo? … The Hwasong-19 missile test comes as North Korea deploys some 10,000 troops inside Russia to support the country’s war against Ukraine. The budding partnership between Russia and North Korea has evolved for several years. Russian President Vladimir Putin has met with North Korean leader Kim Jong Un on multiple occasions, most recently in Pyongyang in June. This has fueled speculation about what Russia is offering North Korea in exchange for the troops deployed on Russian soil. US and South Korean officials have some thoughts. They said North Korea is likely to ask for technology transfers in diverse areas related to tactical nuclear weapons, ICBMs, and reconnaissance satellites.

Virgin Galactic is on the hunt for cash. Virgin Galactic is proposing to raise $300 million in additional capital to accelerate production of suborbital spaceplanes and a mothership aircraft the company says can fuel its long-term growth, Space News reports. The company, founded by billionaire Richard Branson, suspended operations of its VSS Unity suborbital spaceplane earlier this year. VSS Unity hit a monthly flight cadence carrying small groups of space tourists and researchers to the edge of space, but it just wasn’t profitable. Now, Virgin Galactic is developing larger Delta-class spaceplanes it says will be easier and cheaper to turn around between flights.

All-in with Delta … Michael Colglazier, Virgin Galactic’s CEO, announced the company’s appetite for fundraising in a quarterly earnings call with investment analysts Wednesday. He said manufacturing of components for Virgin Galactic’s first two Delta-class ships, which the company says it can fund with existing cash, is proceeding on schedule at a factory in Arizona. Virgin Galactic previously said it would use revenue from paying passengers on its first two Delta-class ships to pay for development of future vehicles. Instead, Virgin Galactic now says it wants to raise money to speed up work on the third and fourth Delta-class vehicles, along with a second airplane mothership to carry the spaceplanes aloft before they release and fire into space.

ESA breaks its silence on Themis. The European Space Agency has provided a rare update on the progress of its Themis reusable booster demonstrator project, European Spaceflight reports. ESA is developing the Themis test vehicle for atmospheric flights to fine-tune technologies for a future European reusable rocket capable of vertical takeoffs and vertical landings. Themis started out as a project led by CNES, the French space agency, in 2018. ESA member states signed up to help fund the project in 2019, and the agency awarded ArianeGroup a contract to move forward with Themis in 2020. At the time, the first low-altitude hop test was expected to take place in 2022.

Some slow progress … Now, the first low-altitude hop is scheduled for 2025 from Esrange Space Centre in Sweden, a three-year delay. This week, ESA said engineers have completed testing of the Themis vehicle’s main systems, and assembly of the demonstrator is underway in France. A single methane-fueled Prometheus engine, also developed by ArianeGroup, has been installed on the rocket. Teams are currently adding avionics, computers, electrical systems, and cable harnesses. Themis’ stainless steel propellant tanks have been manufactured, tested, and cleaned and are now ready to be installed on the Themis demonstrator. Then, the rocket will travel by road from France to the test site in Sweden for its initial low-altitude hops. After those flights are complete, officials plan to add two more Prometheus engines to the rocket and ship it to French Guiana for high-altitude test flights.

SpaceX will give the ISS a boost. A Cargo Dragon spacecraft docked to the International Space Station on Tuesday morning, less than a day after lifting off from Florida. As space missions go, this one is fairly routine, ferrying about 6,000 pounds (2,700 kilograms) of cargo and science experiments to the space station. One thing that’s different about this mission is that it delivered to the station a tiny 2 lb (900 g) satellite named LignoSat, the first spacecraft made of wood, for later release outside the research complex. There is one more characteristic of this flight that may prove significant for NASA and the future of the space station, Ars reports. As early as Friday, NASA and SpaceX have scheduled a “reboost and attitude control demonstration,” during which the Dragon spacecraft will use some of the thrusters at the base of the capsule. This is the first time the Dragon spacecraft will be used to move the space station.

Dragon’s breath … Dragon will fire a subset of its 16 Draco thrusters, each with about 90 pounds of thrust, for approximately 12.5 minutes to make a slight adjustment to the orbital trajectory of the roughly 450-ton space station. SpaceX and NASA engineers will analyze the results from the demonstration to determine if Dragon could be used for future space station reboost opportunities. The data will also inform the design of the US Deorbit Vehicle, which SpaceX is developing to perform the maneuvers required to bring the space station back to Earth for a controlled, destructive reentry in the early 2030s. For NASA, demonstrating Dragon’s ability to move the space station will be another step toward breaking free of reliance on Russia, which is currently responsible for providing propulsion to maneuver the orbiting outpost. Northrop Grumman’s Cygnus supply ship also previously demonstrated a reboost capability. (submitted by Ken the Bin and N35t0r)

Russia launches Soyuz in service of Iran. Russia launched a Soyuz rocket Monday carrying two satellites designed to monitor the space weather around Earth and 53 small satellites, including two Iranian ones, Reuters reports. The primary payloads aboard the Soyuz-2.1b rocket were two Ionosfera-M satellites to probe the ionosphere, an outer layer of the atmosphere near the edge of space. Solar activity can alter conditions in the ionosphere, impacting communications and navigation. The two Iranian satellites on this mission were named Kowsar and Hodhod. They will collect high-resolution reconnaissance imagery and support communications for Iran.

A distant third … This was only the 13th orbital launch by Russia this year, trailing far behind the United States and China. We know of two more Soyuz flights planned for later this month, but no more, barring a surprise military launch (which is possible). The projected launch rate puts Russia on pace for its quietest year of launch activity since 1961, the year Yuri Gagarin became the first person to fly in space. A major reason for this decline in launches is the decisions of Western governments and companies to move their payloads off of Russian rockets after the invasion of Ukraine. For example, OneWeb stopped launching on Soyuz in 2022, and the European Space Agency suspended its partnership with Russia to launch Soyuz rockets from French Guiana. (submitted by Ken the Bin)

H3 deploys Japanese national security satellite. Japan launched a defense satellite Monday aimed at speedier military operations and communication on an H3 rocket and successfully placed it into orbit, the Associated Press reports. The Kirameki 3 satellite will use high-speed X-band communication to support Japan’s defense ministry with information and data sharing, and command and control services. The satellite will serve Japanese land, air, and naval forces from its perch in geostationary orbit alongside two other Kirameki communications satellites.

Gaining trust … The H3 is Japan’s new flagship rocket, developed by Mitsubishi Heavy Industries (MHI) and funded by the Japan Aerospace Exploration Agency (JAXA). The launch of Kirameki 3 marked the third consecutive successful launch of the H3 rocket, following a debut flight in March 2023 that failed to reach orbit. This was the first time Japan’s defense ministry put one of its satellites on the H3 rocket. The first two Kirameki satellites launched on a European Ariane 5 and a Japanese H-IIA rocket, which the H3 will replace. (submitted by Ken the Bin, tsunam, and EllPeaTea)

Rocket Lab enters the race for military contracts. Rocket Lab is aiming to chip away at SpaceX’s dominance in military space launch, confirming its bid to compete for Pentagon contracts with its new medium-lift rocket, Neutron, Space News reports. Last month, the Space Force released a request for proposals from launch companies seeking to join the military’s roster of launch providers in the National Security Space Launch (NSSL) program. The Space Force will accept bids for launch providers to “on-ramp” to the NSSL Phase 3 Lane 1 contract, which doles out task orders to launch companies for individual missions. In order to win a task order, a launch provider must be on the Phase 3 Lane 1 contract. Currently, SpaceX, United Launch Alliance, and Blue Origin are the only rocket companies eligible. SpaceX won all of the first round of Lane 1 task orders last month.

Joining the club … The Space Force is accepting additional risk for Lane 1 missions, which largely comprise repeat launches deploying a constellation of missile-tracking and data-relay satellites for the Space Development Agency. A separate class of heavy-lift missions, known as Lane 2, will require rockets to undergo a thorough certification by the Space Force to ensure their reliability. In order for a launch company to join the Lane 1 roster, the Space Force requires bidders to be ready for a first launch by December 2025. Peter Beck, Rocket Lab’s founder and CEO, said he thinks the Neutron rocket will be ready for its first launch by then. Other new medium-lift rockets, such as Firefly Aerospace’s MLV and Relativity’s Terran-R, almost certainly won’t be ready to launch by the end of next year, leaving Rocket Lab as the only company that will potentially join incumbents SpaceX, ULA, and Blue Origin.

Next Starship flight is just around the corner. Less than a month has passed since the historic fifth flight of SpaceX’s Starship, during which the company caught the booster with mechanical arms back at the launch pad in Texas. Now, another test flight could come as soon as November 18, Ars reports. The improbable but successful recovery of the Starship first stage with “chopsticks” last month, and the on-target splashdown of the Starship upper stage halfway around the world, allowed SpaceX to avoid an anomaly investigation by the Federal Aviation Administration. Thus, the company was able to press ahead on a sixth test flight if it flew a similar profile. And that’s what SpaceX plans to do, albeit with some notable additions to the flight plan.

Around the edges … Perhaps the most significant change to the profile for Flight 6 will be an attempt to reignite a Raptor engine on Starship while it is in space. SpaceX tried to do this on a test flight in March but aborted the burn because the ship’s rolling motion exceeded limits. A successful demonstration of a Raptor engine relight could pave the way for SpaceX to launch Starship into a higher stable orbit around Earth on future test flights. This is required for SpaceX to begin using Starship to launch Starlink Internet satellites and perform in-orbit refueling experiments with two ships docked together. (submitted by EllPeaTea)

China’s version of Starship. China has updated the design of its next-generation heavy-lift rocket, the Long March 9, and it looks almost exactly like a clone of SpaceX’s Starship rocket, Ars reports. The Long March 9 started out as a conventional-looking expendable rocket, then morphed into a launcher with a reusable first stage. Now, the rocket will have a reusable booster and upper stage. The booster will have 30 methane-fueled engines, similar to the number of engines on SpaceX’s Super Heavy booster. The upper stage looks remarkably like Starship, with flaps in similar locations. China intends to fly this vehicle for the first time in 2033, nearly a decade from now.

A vehicle for the Moon … The reusable Long March 9 is intended to unlock robust lunar operations for China, similar to the way Starship, and to some extent Blue Origin’s Blue Moon lander, promises to support sustained astronaut stays on the Moon’s surface. China says it plans to land its astronauts on the Moon by 2030, initially using a more conventional architecture with an expendable rocket named the Long March 10, and a lander reminiscent of NASA’s Apollo lunar lander. These will allow Chinese astronauts to remain on the Moon for a matter of days. With Long March 9, China could deliver massive loads of cargo and life support resources to sustain astronauts for much longer stays.

Ta-ta to the tripod. The large three-legged vertical test stand at SpaceX’s engine test site in McGregor, Texas, is being decommissioned, NASA Spaceflight reports. Cranes have started removing propellant tanks from the test stand, nicknamed the tripod, towering above the Central Texas prairie. McGregor is home to SpaceX’s propulsion test team and has 16 test cells to support firings of Merlin, Raptor, and Draco engines multiple times per day for the Falcon 9 rocket, Starship, and Dragon spacecraft.

Some history … The tripod might have been one of SpaceX’s most important assets in the company’s early years. It was built by Beal Aerospace for liquid-fueled rocket engine tests in the late 1990s. Beal Aerospace folded, and SpaceX took over the site in 2003. After some modifications, SpaceX installed the first qualification version of its Falcon 9 rocket on the tripod for a series of nine-engine test-firings leading up to the rocket’s inaugural flight in 2010. SpaceX test-fired numerous new Falcon 9 boosters on the tripod before shipping them to launch sites in Florida or California. Most recently, the tripod was used for testing of Raptor engines destined to fly on Starship and the Super Heavy booster.

SpaceX prevails over ULA, wins military launch contracts worth $733 million

falcon 9, launch, military space, Science, Space, space force, space systems command, spacex / Beth Washington / October 19, 2024

These missions require medium-lift rockets, or smaller rockets capable of a high-rate launch cadence to match the capability of a larger launch vehicle. In June, the Space Force selected SpaceX, ULA, and Blue Origin, Jeff Bezos’s space company, to compete for Lane 1 launch task orders.

Military officials will add more companies to the pool of available Lane 1 launch providers as they mature their rockets. These companies may include Rocket Lab, Firefly Aerospace, Relativity Space, Stoke Space, and others.

While Blue Origin is on the Space Force’s list of available launch providers, the company’s New Glenn rocket was not eligible for the contracts announced Friday. That’s because military officials require a rocket to complete at least one successful orbital launch to become qualified for a Lane 1 task order. New Glenn’s first test flight is scheduled some time later this year.

This rule left SpaceX’s Falcon 9 and ULA’s Vulcan rockets as the only launch vehicles eligible for the task orders, setting up a head-to-head competition between the rival rocket companies. SpaceX prevailed, winning all nine Lane 1 missions up for competition this year.

Lane 2 of the Space Force’s National Security Space Launch program covers more challenging military missions, typically larger, more expensive payloads destined for higher orbits. The Space Force is expected to soon select launch providers for Lane 2 missions. These launches will require the Space Force to certify the rockets, whereas the military is comfortable accepting a little more risk for the Lane 1 missions.

SpaceX’s Falcon 9 and Falcon Heavy are currently certified for national security launches, and the Space Force is in the process of certifying ULA’s Vulcan launcher after two successful test flights. The Space Force and Blue Origin also have a certification plan for the New Glenn rocket, but it must first complete multiple successful test flights.

Updated October 19 with additional information about the launch task orders.

SpaceX launches Europe’s Hera asteroid mission ahead of Hurricane Milton

The launch of another important mission, NASA’s Europa Clipper, is on hold due to Hurricane Milton.

Two years ago, a NASA spacecraft smashed into a small asteroid millions of miles from Earth to test a technique that could one day prove useful to deflect an object off a collision course with Earth. The European Space Agency launched a follow-up mission Monday to go back to the crash site and see the damage done.

The nearly $400 million (363 million euro) Hera mission, named for the Greek goddess of marriage, will investigate the aftermath of a cosmic collision between NASA’s DART spacecraft and the skyscraper-size asteroid Dimorphos on September 26, 2022. NASA’s Double Asteroid Redirection Test mission was the first planetary defense experiment, and it worked, successfully nudging Dimorphos off its regular orbit around a larger companion asteroid named Didymos.

But NASA had to sacrifice the DART spacecraft in the deflection experiment. Its destruction meant there were no detailed images of the condition of the target asteroid after the impact. A small Italian CubeSat deployed by DART as it approached Dimorphos captured fuzzy long-range views of the collision, but Hera will perform a comprehensive survey when it arrives in late 2026.

“We are going to have a surprise to see what Dimorphos looks like, which is, first, scientifically exciting, but also important because if we want to validate the technique and validate the model that can reproduce the impact, we need to know the final outcome,” said Patrick Michel, principal investigator on the Hera mission from Côte d’Azur Observatory in Nice, France. “And we don’t have it. With Hera, it’s like a detective going back to the crime scene and telling us what really happened.”

Last ride before the storm

The Hera spacecraft, weighing in at 2,442 pounds (1,108 kilograms), lifted off on top of a SpaceX Falcon 9 rocket at 10: 52 am EDT (14: 52 UTC) Monday from Cape Canaveral Space Force Station, Florida.

Officials weren’t sure the weather conditions at Cape Canaveral would permit a launch Monday, with widespread rain showers and a blanket of cloud cover hanging over Florida’s Space Coast. But the conditions were just good enough to be acceptable for a rocket launch, and the Falcon 9 lit its nine kerosene-fueled engines to climb away from pad 40 after a smooth countdown.

This was probably the final opportunity to launch Hera before the spaceport shutters in advance of Hurricane Milton, a dangerous Category 5 storm taking aim at the west coast of Florida. If the mission didn’t launch Monday, SpaceX was prepared to move the Falcon 9 rocket and the Hera spacecraft back inside a hangar for safekeeping until the storm passes.

Meanwhile, at NASA’s Kennedy Space Center a few miles away, SpaceX is securing a Falcon Heavy rocket with the Europa Clipper spacecraft to ride out Hurricane Milton inside a hangar at Launch Complex 39A. Europa Clipper is a $5.2 billion flagship mission to explore Jupiter’s most enigmatic icy moon, and it was supposed to launch Thursday, the same day Hurricane Milton will potentially move over Central Florida.

NASA announced Sunday that it is postponing Europa Clipper’s launch until after the storm.

“The safety of launch team personnel is our highest priority, and all precautions will be taken to protect the Europa Clipper spacecraft,” said Tim Dunn, senior launch director at NASA’s Launch Services Program. “Once we have the ‘all-clear’ followed by facility assessment and any recovery actions, we will determine the next launch opportunity for this NASA flagship mission.”

Europa Clipper must launch by November 6 in order to reach Jupiter and its moon Europa in 2030. ESA’s Hera mission had a similarly tight window to get off the ground in October and arrive at asteroids Didymos and Dimorphos in December 2026.

Returning to flight

The Falcon 9 did its job Monday, accelerating the Hera spacecraft to a blistering speed of 26,745 mph (43,042 km/hr) with successive burns by its first stage booster and upper stage engine. This was the highest-speed payload injection ever achieved by SpaceX.

SpaceX did not attempt to recover the Falcon 9’s reusable booster on Monday’s flight because Hera needed all of the rocket’s oomph to gain enough speed to escape the pull of Earth’s gravity.

“Good launch, good orbit, and good payload deploy,” wrote Kiko Dontchev, SpaceX’s vice president of launch, on X.

This was the first Falcon 9 launch in nine days—an unusually long gap between SpaceX missions—after the rocket’s upper stage misfired during a maneuver to steer itself out of orbit following an otherwise successful launch September 28 with a two-man crew heading for the International Space Station.

The upper stage engine apparently “over-burned,” and the rocket debris fell into the atmosphere short of its expected reentry corridor in the Pacific Ocean, sources said. The Federal Aviation Administration grounded the Falcon 9 rocket while SpaceX investigates the malfunction, but the FAA granted approval for SpaceX to launch the Hera mission because its trajectory would carry the rocket away from Earth, rather than back into the atmosphere for reentry.

“The FAA has determined that the absence of a second stage reentry for this mission adequately mitigates the primary risk to the public in the event of a reoccurrence of the mishap experienced with the Crew-9 mission,” the FAA said in a statement.

This was the third time the FAA has grounded SpaceX’s Falcon 9 rocket fleet in less than three months, following another upper stage failure in July that caused the destruction of 20 Starlink Internet satellites and the crash-landing of a Falcon 9 booster on an offshore drone ship in August. Federal regulators are responsible for ensuring commercial rocket launches don’t endanger the public.

These were the first major anomalies on any Falcon 9 launch since 2021.

It’s not clear when the FAA will clear SpaceX to resume launching other Falcon 9 missions. However, the launch of the Europa Clipper mission on a Falcon Heavy rocket, which uses essentially the same upper stage as a Falcon 9, is not licensed by the FAA because it is managed by NASA, another government agency. NASA will have final authority on whether to give the green light for the launch of Europa Clipper.

Surveying the damage

ESA’s Hera spacecraft is on course for a flyby of Mars next March to take advantage of the red planet’s gravity to slingshot itself on a trajectory to intercept its twin target asteroids. Near Mars, Hera will zoom relatively close to the planet’s asteroid-like moon, Deimos, to obtain rare closeups.

Then, Hera will approach Didymos and Dimorphos a little more than two years from now, maneuvering around the binary asteroid system at a range of distances, eventually moving as close as about a half-mile (1 kilometer) away.

Dimorphos orbits Didymos once every 11 hours and 23 minutes, roughly 32 minutes shorter than the orbital period before DART’s impact in 2022. This change in orbit proved the effectiveness of a kinetic impactor in deflecting an asteroid that threatens Earth.

Dimorphos, the smaller of the two asteroids, has a diameter of around 500 feet (150 meters), while Didymos measures approximately a half-mile (780 meters) wide. Neither asteroid poses a risk to Earth, so NASA chose them as the objective for DART.

The Hubble Space Telescope spotted a debris field trailing the binary asteroid system after DART’s impact. Astronomers identified at least 37 boulders drifting away from the asteroids, material ejected when the DART spacecraft slammed into Dimorphos at a velocity of 14,000 mph (22,500 kmh).

Scientists will use Hera, with its suite of cameras and instruments, to study how the strike by DART changed the asteroid Dimorphos. Did the impact leave a crater, or did it reshape the entire asteroid? There are “tentative hints” that the asteroid’s shape changed after the collision, according to Michael Kueppers, Hera’s project scientist at ESA.

“If this is the case, it would also mean that the cohesion of Dimorphos is extremely low; that indeed, even an object the size of Dimorphos would be held together by its weight, by its gravity, and not by cohesion,” Kueppers said. “So it really would be a rubble pile.”

Hera will also measure the mass of Dimorphos, something DART was unable to do. “That is important to measure the efficiency of the impact… which was the momentum that was transferred from the impacting satellite to the asteroid,” Kueppers said.

The central goal of Hera is to fill the gaps in knowledge about Didymos and Dimorphos. Precise measurements of DART’s momentum, coupled with a better understanding of the interior structure of the asteroids, will allow future mission planners to know how best to deflect a hazardous object threatening Earth.

“The third part is to generally investigate the two asteroids to know their physical properties, their interior properties, their strength, essentially to be able to extrapolate or to scale the outcome of DART to another impact should we really need it one day,” Kueppers said.

Hera will release two briefcase-size CubeSats, named Juventas and Milani, to work in concert with ESA’s mothership. Juventas carries a compact radar to probe the internal structure of the smaller asteroid and will eventually attempt a landing on Dimorphos. Milani will study the mineral composition of individual boulders around DART’s impact site.

“This is the first time that we send a spacecraft to a small body, which is actually a multi-satellite system, with one main spacecraft and two CubeSats doing closer proximity operations,” Michel said. “This has never been done.”

One source of uncertainty, and perhaps worry, about the environment around Didymos and Dimorphos is the status of the debris field observed by Hubble a few months after DART’s impact. But this is not likely to be a problem, according to Kueppers.

“I’m not really worried about potential boulders at Didymos,” he said, recalling the relative ease with which ESA’s Rosetta spacecraft navigated around an active comet from 2014 through 2016.

Ignacio Tanco, ESA’s flight director for Hera, doesn’t share Kuepper’s optimism.

“We didn’t hit the comet with a hammer,” said Tanco, who is responsible for keeping the Hera spacecraft safe. “The debris question for me is actually a source of… I wouldn’t say concern, but certainly precaution. It’s something that we’ll need to approach carefully once we get there.”

“That’s the difference between an engineer and a scientist,” Kuepper joked.

Scientists originally wanted Hera to be in the vicinity of the Didymos binary asteroid system before DART’s arrival, allowing it to directly observe the impact and its fallout. But ESA’s member states did not approve funding for the Hera mission in time, and the space agency only signed the contract to build the Hera spacecraft in 2020.

ESA first studied a mission like DART and Hera more than 20 years ago, when scientists proposed a mission called Don Quijote to get an asteroid deflection. But other missions took priority in Europe’s space program. Now, Hera is on course to write the final chapter of the story of humanity’s first planetary defense test.

“This is our contribution of ESA to humanity to help us in the future protect our planet,” said Josef Aschbacher, ESA’s director general.
