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.

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.”

As preps continue, it’s looking more likely NASA will fly the Artemis II mission

NASA’s existing architecture still has a limited shelf life, and the agency will probably have multiple options for transporting astronauts to and from the Moon in the 2030s. A decision on the long-term future of SLS and Orion isn’t expected until the Trump administration’s nominee for NASA administrator, Jared Isaacman, takes office after confirmation by the Senate.

So, what is the plan for SLS?

There are different degrees of cancellation options. The most draconian would be an immediate order to stop work on Artemis II preparations. This is looking less likely than it did a few months ago and would come with its own costs. It would cost untold millions of dollars to disassemble and dispose of parts of Artemis II’s SLS rocket and Orion spacecraft. Canceling multibillion-dollar contracts with Boeing, Northrop Grumman, and Lockheed Martin would put NASA on the hook for significant termination costs.

Of course, these liabilities would be less than the $4.1 billion NASA’s inspector general estimates each of the first four Artemis missions will cost. Most of that money has already been spent for Artemis II, but if NASA spends several billion dollars on each Artemis mission, there won’t be much money left over to do other cool things.

Other options for NASA might be to set a transition point when the Artemis program would move off of the Space Launch System rocket, and perhaps even the Orion spacecraft, and switch to new vehicles.

Another possibility, which seems to be low-hanging fruit for Artemis decision-makers, could be to cancel the development of a larger Exploration Upper Stage for the SLS rocket. If there are a finite number of SLS flights on NASA’s schedule, it’s difficult to justify the projected $5.7 billion cost of developing the upgraded Block 1B version of the Space Launch System. There are commercial options available to replace the rocket’s Boeing-built Exploration Upper Stage, as my colleague Eric Berger aptly described in a feature story last year.

For now, it looks like NASA’s orange behemoth has a little life left in it. All the hardware for the Artemis II mission has arrived at the launch site in Florida.

The Trump administration will release its fiscal-year 2026 budget request in the coming weeks. Maybe then NASA will also have a permanent administrator, and the veil will lift over the White House’s plans for Artemis.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

NASA says Orion’s heat shield is good to go for Artemis II—but does it matter?

“We have since determined that while the capsule was dipping in and out of the atmosphere, as part of that planned skip entry, heat accumulated inside the heat shield outer layer, leading to gases forming and becoming trapped inside the heat shield,” said Pam Melroy, NASA’s deputy administrator. “This caused internal pressure to build up and led to cracking and uneven shedding of that outer layer.”

An independent team of experts concurred with NASA’s determination of the root cause, Melroy said.

Counterintuitively, this means NASA engineers are comfortable with the safety of the heat shield if the Orion spacecraft reenters the atmosphere at a slightly steeper angle than it did on Artemis I and spends more time subjected to higher temperatures.

When the Orion spacecraft climbed back out of the atmosphere during the Artemis I skip reentry, a period known as the skip dwell, NASA said heating rates decreased and thermal energy accumulated inside the heat shield’s Avcoat material. This generated gases inside the heat shield through a process known as pyrolysis. 

“Pyrolysis is just burning without oxygen,” said Amit Kshatriya, deputy associate administrator of NASA’s Moon to Mars program. “We learned that as part of that reaction, the permeability of the Avcoat material is essential.”

During the skip dwell, “the production of those gases was higher than the permeability could tolerate, so as a result, pressure differential was created. That pressure led to cracks in plane with the outer mold line of the vehicle,” Kshatriya said.

NASA didn’t know this could happen because engineers tested the heat shield on the ground at higher temperatures than the Orion spacecraft encountered in flight to prove the thermal barrier could withstand the most extreme possible heating during reentry.

“What we missed was this critical region in the middle, and we missed that region because we didn’t have the test facilities to produce the low-level energies that occur during skip and dwell,” Kshatriya said Thursday.

During the investigation, NASA replicated the charring and cracking after engineers devised a test procedure to expose Avcoat heat shield material to the actual conditions of the Artemis I reentry.

So, for Artemis II, NASA plans to modify the reentry trajectory to reduce the skip reentry’s dwell time. Let’s include some numbers to help illustrate the difference.

The distance traveled by Artemis I during the reentry phase of the mission was more than 3,000 nautical miles (3,452 miles; 5,556 kilometers), according to Kshatriya. This downrange distance will be limited to no more than 1,775 nautical miles (2,042 miles; 3,287 kilometers) on Artemis II, effectively reducing the dwell time the Orion spacecraft spends in the lower heating regime that led to the cracking on Artemis I.

With this change, Kshatriya said NASA engineers don’t expect to see the heat shield erosion they saw on Artemis I. “The gas generation that occurs during that skip dwell is sufficiently low that the environment for crack generation is not going to overwhelm the structural integrity of the char layer.”

For future Orion spaceships, NASA and its Orion prime contractor, Lockheed Martin, will incorporate changes to address the heat shield’s permeability problem.

Waiting for what?

NASA officials discussed the heat shield issue, and broader plans for the Artemis program, in a press conference in Washington on Thursday. But the event’s timing added a coat of incredulity to much of what they said. President-elect Donald Trump, with SpaceX founder Elon Musk in his ear, has vowed to cut wasteful government spending.

A good sign

The readiness of the Orion crew capsule, where the four Artemis II astronauts will live during their voyage around the Moon, is driving NASA’s schedule for the mission. Officially, Artemis II is projected to launch in September of next year, but there’s little chance of meeting that schedule.

At the beginning of this year, NASA officials ruled out any opportunity to launch Artemis II in 2024 due to several technical issues with the Orion spacecraft. Several of these issues are now resolved, but NASA has not released any meaningful updates on the most significant problem.

This problem involves the Orion spacecraft’s heat shield. During atmospheric reentry at the end of the uncrewed Artemis I test flight in 2022, the Orion capsule’s heat shield eroded and cracked in unexpected ways, prompting investigations by NASA engineers and an independent panel.

NASA’s Orion heat shield inquiry ran for nearly two years. The investigation has wrapped up, two NASA officials said last month, but they declined to discuss any details of the root cause of the heat shield issue or the actions required to resolve the problem on Artemis II.

These corrective options ranged from doing nothing to changing the Orion spacecraft’s reentry angle to mitigate heating or physically modifying the Artemis II heat shield. In the latter scenario, NASA would have to disassemble the Orion spacecraft, which is already put together and is undergoing environmental testing at Kennedy Space Center. This would likely delay the Artemis II launch by a couple of years.

In August, NASA’s top human exploration official told Ars that the agency would hold off on stacking the SLS rocket until engineers had a good handle on the heat shield problem. There are limits to how long the solid rocket boosters can remain stacked vertically. The joints connecting each segment of the rocket motors are certified for one year. This clock doesn’t actually start ticking until NASA stacks the next booster segments on top of the lowermost segments.

However, NASA waived this rule on Artemis I when the boosters were stacked nearly two years before the successful launch.

A NASA spokesperson told Ars on Wednesday that the agency had nothing new to share on the Orion heat shield or what changes, if any, are required for the Artemis II mission. This information should be released before the end of the year, she said. At the same time, NASA could announce a new target launch date for Artemis II at the end of 2025, or more likely in 2026.

But because NASA gave the “go” for SLS stacking now, it seems safe to rule out any major hardware changes on the Orion heat shield for Artemis II.

Rocket delivered to launch site for first human flight to the Moon since 1972

The central piece of NASA’s second Space Launch System rocket arrived at Kennedy Space Center in Florida this week. Agency officials intend to start stacking the towering launcher in the next couple of months for a mission late next year carrying a team of four astronauts around the Moon.

The Artemis II mission, officially scheduled for September 2025, will be the first voyage by humans to the vicinity of the Moon since the last Apollo lunar landing mission in 1972. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian mission specialist Jeremy Hansen will ride the SLS rocket away from Earth, then fly around the far side of the Moon and return home inside NASA’s Orion spacecraft.

“The core is the backbone of SLS, and it’s the backbone of the Artemis mission,” said Matthew Ramsey, NASA’s mission manager for Artemis II. “We’ve been waiting for the core to get here because all the integrated tests and checkouts that we do have to have the core stage. It has the flight avionics that drive the whole system. The boosters are also important, but the core is really the backbone for Artemis. So it’s a big day.”

The core stage rolled off of NASA’s Pegasus barge at Kennedy early Wednesday, following a weeklong ocean voyage from New Orleans, where Boeing builds the rocket under contract to NASA.

Ramsey told Ars that ground teams hope to begin stacking the rocket’s two powerful solid rocket boosters on NASA’s mobile launcher platform in September. Each booster, supplied by Northrop Grumman, is made of five segments with pre-packed solid propellant and a nose cone. All the pieces for the SLS boosters are at Kennedy and ready for stacking, Ramsey said.

The SLS upper stage, built by United Launch Alliance, is also at the Florida launch site. Now, the core stage is at Kennedy. In August or September, NASA plans to deliver the two remaining elements of the SLS rocket to Florida. These are the adapter structures that will connect the core stage to the upper stage, and the upper stage to the Orion spacecraft.

A heavy-duty crane inside the cavernous Vehicle Assembly Building (VAB) will hoist each segment of the SLS boosters into place on the launch platform. Once the boosters are fully stacked, ground teams will lift the 212-foot (65-meter) core stage vertical in the transfer aisle running through the center of the VAB. A crane will then lower the core stage between the boosters. That could happen as soon as December, according to Ramsey.

Then comes the launch vehicle stage adapter, the upper stage, the Orion stage adapter, and finally, the Orion spacecraft itself.

Moving toward operations

NASA’s inspector general reported in 2022 that NASA’s first four Artemis missions will each cost $4.1 billion. Subsequent documents, including a Government Accountability Office report last year, suggest the expendable SLS core stage is responsible for at least a quarter of the cost for each Artemis flight.

The core stage for Artemis II is powered by four hydrogen-fueled RS-25 engines produced by Aerojet Rocketdyne. Two of the reusable engines for Artemis II have flown on the space shuttle, and the other two RS-25s were built in the shuttle era but never flew. Each SLS launch will put the core stage and its engines in the Atlantic Ocean.

Steve Wofford, who manages the stages office for the SLS program at NASA’s Marshall Space Flight Center, told Ars there are “no major configuration differences” between the core stages for Artemis I and Artemis II. The only minor differences involve instrumentation that NASA wanted on Artemis I to measure pressures, accelerations, vibrations, temperatures, and other parameters on the first flight of the Space Launch System.

“We are still working off some flight observations that we made on Artemis I, but no showstoppers,” Wofford said. “On the first article, the test flight, Artemis I, we really loaded it up. That’s a golden opportunity to learn as much as you can about the vehicle and the flight regime, and anchor all your models… As you progress, you need less and less of that. So Core Stage 2 will have less development flight instrumentation than Core Stage 1, and then Core Stage 3 will have less still.”

Welcome to Edition 7.03 of the Rocket Report! One week ago, SpaceX suffered a rare failure of its workhorse Falcon 9 rocket. In fact, it was the first time the latest version of the Falcon 9, known as the Block 5, has ever failed on its prime mission after nearly 300 launches. The world’s launch pads have been silent since the grounding of the Falcon 9 fleet after last week’s failure. This isn’t surprising, but it’s noteworthy. After all, the Falcon 9 has flown more this year than all of the world’s other rockets combined and is fundamental to much of what the world does in space.

Astra finally goes private, again. A long-simmering deal for Astra’s founders to take the company private has been finalized, the company announced Thursday, capping the rocket launch company’s descent from blank-check darling to delisting in three years, Bloomberg reports. The launch company’s valuation peaked at $3.9 billion in 2021, the year it went public, and was worth about $12.2 million at the end of March, according to data compiled by Bloomberg. Astra’s chief executive officer, Chris Kemp, and chief technology officer, Adam London, founded the company in 2016 with the goal of essentially commoditizing launch services for small satellites. But Astra’s rockets failed to deliver and fell short of orbit five times in seven tries.

Spiraling … Astra’s stock price tanked after the spate of launch failures, drying up its funding spigot as Kemp tried to pivot toward a slightly larger, more reliable rocket. Astra acquired a company named Apollo Fusion in 2021, entering a new business segment to produce electric thrusters for small satellites. But Astra’s launch business faltered, and last November Kemp and London submitted an offer to retake ownership of the company. Astra announced the closure of the take-private deal Thursday, with Kemp and London acquiring the company’s outstanding shares for 50 cents per share in cash, below the stock’s final listing price of 53 cents. “We will now focus all of our attention on a successful launch of Rocket 4, delivering satellite engines to our customers, and building a company of consequence,” Kemp said.

Firefly chief leaves company. Launch startup Firefly Aerospace parted ways with CEO Bill Weber, Payload reports. The announcement of Weber’s departure late Wednesday came two days after Payload reported Firefly was investigating claims of an alleged inappropriate relationship between him and a female employee. “Firefly Aerospace’s Board of Directors announced that Bill Weber is no longer serving as CEO of the company, effective immediately,” the company said in a statement Wednesday night. Peter Schumacher takes over as interim CEO while Firefly searches for a new permanent chief executive. Schumacher was an interim CEO at Firefly before Weber’s hiring in 2022.

Two days and gone … Payload published the first report of Weber’s alleged improper relationship with a female employee Monday. Two days later, Weber was gone. Payload reported an executive brought his concerns about the alleged relationship to Firefly’s board and resigned because he lost confidence in leadership at the company. Citing four current and former employees, Payload reported Firefly’s culture became “chaotic” since Weber took the helm in 2022 after its acquisition by AE Industrial Partners. The Texas-based company achieved some success during Weber’s tenure, with four orbital launches of its Alpha rocket, although two of the flights ended up in lower-than-planned orbits.

Themis hop tests delayed to next year. The initial hop tests of the European Themis reusable booster, developed by ArianeGroup and funded by ESA, won’t start until next year, European Spaceflight reports. The Swedish Space Corporation, which operates the space center in Sweden where Themis will initially fly, confirmed the schedule change. Once ArianeGroup moves on to higher altitude flights, the testing will be moved to the Guiana Space Center. ESA awarded the first development contract for the Themis booster in 2019, and the first hop tests were then scheduled for 2022. Themis’ hops will be similar to SpaceX’s Grasshopper rocket, which performed a series of up-and-down atmospheric test flights before SpaceX started recovering and reusing Falcon 9 boosters.

Fate of Themis … The Themis booster is powered by the methane-fueled Prometheus engine, also funded by ESA. A large European reusable rocket is unlikely to fly until the 2030s, but a subsidiary of ArianeGroup named MaiaSpace is developing a smaller partially reusable two-stage rocket slated to debut as soon as next year. The Maia rocket will use a modified Themis booster as its first stage. “As a result, for MaiaSpace, the continued and rapid development of the Themis program is essential to ensure it can hit its projected target of an inaugural flight of Maia in 2025,” European Spaceflight reports.

Welcome to Edition 6.27 of the Rocket Report! This week, we discuss an intriguing new report looking at Starship. Most fascinating, the report covers SpaceX’s costs to build a Starship and how these costs will come down as the company ramps up its build and launch cadence. At the other end of the spectrum, former NASA Administrator Mike Griffin has a plan to get astronauts back to the Moon that would wholly ignore the opportunities afforded by Starship.

The problem at America’s military spaceports. The Biden administration is requesting $1.3 billion over the next five years to revamp infrastructure at the Space Force’s ranges in Florida and California, Ars reports. This will help address things like roads, bridges, utilities, and airfields that, in many cases, haven’t seen an update in decades. But it’s not enough, according to the Space Force. Last year, Cape Canaveral was the departure point for 72 orbital rocket launches, and officials anticipate more than 100 this year. The infrastructure and workforce at the Florida spaceport could support about 150 launches in a year without any major changes, but launch activity is likely to exceed that number within a few years.

Higher fees incoming … Commercial launch companies operating from Cape Canaveral Space Force Station, Florida, or Vandenberg Space Force Base, California, pay fees to the Space Force to reimburse for direct costs related to rocket launches. These cover expenses like weather forecast services, surveillance to ensure airplanes and boats stay out of restricted areas, and range safety support. “What that typically meant was anything we did that was specifically dedicated to that launch,” said Col. James Horne, deputy commander of the Space Force’s assured access to space directorate. This is about to change after legislation passed by Congress in December allows the Space Force to charge indirect fees to commercial providers. This money will go into a fund to pay for maintenance and upgrades to infrastructure used by all launch companies at the spaceports.

Momentus is running out of money. Momentus, a company that specializes in “last mile” satellite delivery services, announced on January 12 that it is running out of money and does not have a financial lifeline, CNBC reports. The company was once valued at more than $1 billion before going public via a Special Purpose Acquisition Company (SPAC) in 2021 but now has a market capitalization of less than $10 million. Momentus has developed a space tug called Vigoride, designed to place small satellites into bespoke orbits after deploying from a larger rocket on a rideshare mission, such as a SpaceX Falcon 9. Now, Momentus is abandoning plans for its next mission that was due for launch in March. In December, the company laid off about 20 percent of its workforce to reduce costs.

Fatal blow? … Momentus may have received a potentially fatal blow after losing the US Space Development Agency’s recent competition for 18 so-called Tranche 2 satellites, Aviation Week reports. Instead, the SDA made recent satellite manufacturing contract awards to Rocket Lab, L3Harris, Lockheed Martin, and Sierra Space. On Wednesday, Momentus announced it closed a $4 million stock sale. This should keep Momentus afloat for a while longer but won’t provide the level of capital needed to undertake any significant manufacturing or technical development work. (submitted by Ken the Bin)

Orbex may go bigger. UK-based launch startup Orbex hasn’t yet flown its small satellite launcher, called Prime, but is already looking at what’s next, according to reports by European Spaceflight and the Financial Times. New Orbex CEO Phil Chambers, who was officially appointed earlier this month, told the Financial Times that the company was already discussing the possibility of developing a larger vehicle. Speaking to European Spaceflight, Chambers described the business model to deliver orbital launch services with Prime as “robust.” Despite this, he admitted that the small launch industry was only a small sliver of the overall launch market.

Learning to walk before running … While future growth is on Orbex’s radar, its near-term focus is completing construction of a spaceport in Scotland, launching a maiden flight of Prime, and delivering on the six flights the company has already sold. The two-stage Prime rocket, fueled by “bio-propane,” will be capable of hauling a payload of approximately 180 kilograms (nearly 400 pounds) into low-Earth orbit. But Orbex has been shy about releasing updates on the progress of the Prime rocket’s development since unveiling a full-scale mock-up of the launch vehicle in 2022. Last year, the CEO who led Orbex since its founding resigned. Its most recent significant funding round was valued at 40.4 million pounds in late 2022. (submitted by Ken the Bin)
