Momentum seems to be building for Jared Isaacman to become NASA administrator

With the vast majority of President Donald Trump’s cabinet members now approved by the US Senate, focus is turning to senior positions within the administration that are just below the cabinet level.

The administrator of NASA is among the most high-profile of these positions. Nearly four months ago Trump nominated private astronaut Jared Isaacman to become chief of the space agency, but he has yet to receive a hearing before the Senate Committee on Commerce, Science, and Transportation.

Almost immediately after his nomination, much of the space community fell in behind Isaacman, who has flown to space twice on private Crew Dragon missions, raised charitable funds, and is generally well-liked. Since then, Isaacman has worked to build support for his candidacy through conversations with people in the space community and officeholders.

However, publicly, not much has happened. This has raised questions within the space community about whether the nomination has stalled. Although some people have expressed concern about financial ties between Isaacman and SpaceX, according to multiple sources, the primary obstacle has been Ted Cruz, the Texas Republican who chairs the Senate committee.

Cruz is not happy that Isaacman has donated to Democrats in the past, and he is concerned that the private astronaut is more interested in Mars exploration than the Moon. Cruz also did not appreciate Elon Musk’s call to end the life of the International Space Station early. The station is operated by NASA’s field center, Johnson Space Center, in Houston, where Cruz lives.

Nomination on track

Nevertheless, despite the slower pace, people familiar with the nomination process say Isaacman’s candidacy remains on track. And recently, there have been some public announcements that support this notion.

In early March, the governors of several southern US states, including Florida and Texas, sent a letter to Cruz expressing “strong support” for the swift confirmation of Isaacman. A notable absence from this letter was the governor of Alabama, Kay Ivey, where NASA’s Marshall Space Flight Center is located. However, she also recently sent Cruz a letter praising Isaacman, calling him an “exceptional selection” to lead NASA. It is notable that the governors of all the US states with major human spaceflight activities have now lined up behind Isaacman.

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.

This launcher is about to displace the V-2 as Germany’s largest rocket


Isar Aerospace’s first Spectrum rocket will launch from Andøya Spaceport in Norway.

Seven years ago, three classmates at the Technical University of Munich believed their student engineering project might hold some promise in the private sector.

At the time, Daniel Metzler led a team of 40 students working on rocket engines and launching sounding rockets. Josef Fleischmann was on the team that won the first SpaceX Hyperloop competition. Together with another classmate, Markus Brandl, they crafted rocket parts in a campus workshop before taking the leap and establishing Isar Aerospace, named for the river running through the Bavarian capital.

Now, Isar’s big moment has arrived. The company’s orbital-class first rocket, named Spectrum, is set to lift off from a shoreline launch pad in Norway as soon as Monday.

The three-hour launch window opens at 12: 30 pm local time in Norway, or 7: 30 am EDT in the United States. “The launch date remains subject to weather, safety and range infrastructure,” Isar said in a statement.

Isar said it received a launch license from the Norwegian Civil Aviation Authority on March 14, following the final qualification test on the Spectrum rocket in February to validate its readiness for flight.

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.

No guarantees

Success is never assured on the inaugural launch of a new rocket. Isar is the first in a wave of European launch startups to arrive at this point. The company developed the Spectrum rocket with mostly private funding, although Isar received multimillion-euro investments from the European Space Agency, the German government, and the NATO Innovation Fund.

All told, Isar says it has raised more than 400 million euros, or $435 million at today’s currency exchange rate, more than any other European launch startup.

“We are approaching the most important moment of our journey so far, and I would like to thank all our team, partners, customers and investors who have been accompanying and trusting us,” said Daniel Metzler, Isar’s co-founder and CEO, in a statement.

Most privately developed rockets have failed to reach orbit on the first try. Several US launch companies that evolved in a similar mold as Isar—such as Rocket Lab, Firefly Aerospace, and Astra—faltered on the way to orbit on their rockets’ first flights.

“With this mission, Isar Aerospace aims to collect as much data and experience as possible on its in-house-developed launch vehicle. It is the first integrated test of all systems,” said Alexandre Dalloneau, Isar’s vice president of mission and launch operations.

“The test results will feed into the iterations and development of future Spectrum vehicles, which are being built and tested in parallel,” Isar said in a statement.

Europe has struggled to regain its footing after SpaceX took over the dominant position in the global commercial launch market, a segment led for three decades by Europe’s Ariane rocket family before SpaceX proved the reliability of the lower-cost, partially reusable Falcon 9 launcher. The continent’s new Ariane 6 rocket, funded by ESA and built by a consortium owned by multinational firms Airbus and Safran, is more expensive than the Falcon 9 and years behind schedule. It finally debuted last year.

One ton to LEO

Isar’s Spectrum rocket is not as powerful as SpaceX’s Falcon 9 or Arianespace’s Ariane 6. But even SpaceX had to start somewhere. Its small Falcon 1 rocket failed three times before tasting success. Spectrum is somewhat larger and more capable than Falcon 1, with performance in line with Firefly’s Alpha rocket.

The fully assembled Spectrum rocket stands about 92 feet (28 meters) tall and measures more than 6 feet (2 meters) in diameter. The expendable launcher is designed to haul payloads up to 1 metric ton (2,200 pounds) into low-Earth orbit. Spectrum is powered by nine Aquila engines on its first stage, and one engine on the second stage, burning a mixture of propane and liquid oxygen propellants.

There are no customer satellites aboard the first Spectrum test flight. The rocket will climb into a polar orbit from Andøya Spaceport in northern Norway, but Isar hasn’t published a launch timeline or the exact parameters of the target orbit.

While modest in size next to Europe’s Ariane launcher family, Isar’s Spectrum is the largest German rocket since the V-2, the World War II weapon of terror launched by Nazi Germany against targets in Great Britain, Belgium, and other places. In the 80 years since the war, German industry developed a handful of small sounding rockets and manufactured upper stages for Ariane rockets.

But German governments have long shunned spending on launchers at levels commensurate with the nation’s place as a top contributor to ESA. France took the lead in the continent’s postwar rocket industry, providing the lion’s share of funding for Ariane and taking responsibility for building engines and booster stages.

Now, 80 years to the week since the last V-2 launch of World War II, Germany again has a homegrown liquid-fueled rocket on the launch pad. This time, it’s for a much different purpose.

As a first step, Isar and other companies in Europe are vying to inject competition with Arianespace into the European launch market. This will begin with small government-funded satellites that otherwise would have likely launched on rideshare flights by SpaceX or Arianespace.

In 2022, the German space agency (known as DLR) announced the selection of research and demo payloads slated to fly on Spectrum’s second launch. The Norwegian Space Agency revealed a contract earlier this month for Isar to launch a pair of satellites for the country’s Arctic Ocean Surveillance program.

Within the next few days, ESA is expected to release an “invitation to tender” for European industry to submit proposals for the European Launcher Challenge. This summer, ESA will select winners from Europe’s crop of launch startups to demonstrate that their rockets can deliver the agency’s scientific satellites to orbit. This is the first time ESA has experimented with a fully commercial business model, with launch service contracts to private companies. Isar is a leading contender to win the launcher challenge, alongside other European companies like Rocket Factory Augsburg, HyImpulse, MaiaSpace, and others.

Previously, ESA has provided billions of euros to Europe’s big incumbent rocket companies for development of new generations of Ariane rockets. Now, ESA wants to follow the path of NASA, which has used fixed-price service contracts to foster commercial cargo and crew transportation to the International Space Station, and most recently, privately owned landers on the Moon.

“Whatever the outcome, Isar Aerospace’s upcoming Spectrum launch will be historic: the first commercial orbital launch from mainland Europe,” Josef Aschbacher, ESA’s director general, posted on X. “The support and co-funding the European Space Agency has given Isar Aerospace and other launch service provider startups is paying off for increased autonomy in Europe. Wishing Isar Aerospace a great launch day with fair weather and most importantly, that the data they receive from the liftoff will speed next iterations of their rockets.”

Toni Tolker-Nielsen, ESA’s acting director of space transportation, called this moment a “paradigm shift” for Europe’s launcher strategy.

“In the last 40 years, we have had these ESA-developed launchers that we have been relying on,” Tolker-Nielsen told Ars in an interview. “So we started with Ariane 1 up to Ariane 6. Vega C came onboard. And it’s been working like that for the last 40 years. Now, we are moving into in the ’30s, and the next decades, to have privately developed launchers.”

Isar Aerospace’s first Spectrum rocket will lift off from the remote Andøya Spaceport in Norway, a gorgeous location that might be the world’s most picturesque launch site. Nestled on the western coast of an island inside the Arctic Circle, Andøya offers an open path over the Norwegian Sea for rockets to fly north, where they can place satellites into polar orbit.

The spaceport is operated by Andøya Space, a company 90 percent owned by the Norwegian government through the Ministry for Trade, Industry, and Fisheries. Until now, Andøya Spaceport has been used for launches of suborbital sounding rockets.

No better time than now

Isar’s first launch comes amid an abrupt turn in European strategic policy as the continent’s leaders struggle with how to respond to moves by President Donald Trump in his first two months in office. In recent weeks, the Trump administration put European leaders on their heels with sudden policy reversals and unpredictable statements on Ukraine, NATO, and the US government’s long-term backstopping of European security.

Friedrich Merz, set to become Germany’s next chancellor, said last month that Europe should strive to “achieve independence” from the United States. “It is clear that the Americans, at least this part of the Americans, this administration, are largely indifferent to the fate of Europe.”

Last week, Merz shepherded a bill through German parliament to amend the country’s constitution, allowing for a significant increase in German defense spending. The incoming chancellor said the change is “nothing less than the first major step towards a new European defense community.”

The erosion of Europe’s trust in the Trump administration prompted rumors that the US government could trigger a “kill switch” to turn off combat capabilities of F-35 fighter jets sold to US allies. This would have previously seemed like a far-fetched conspiracy theory, but some European officials felt compelled to make statements denying the kill switch reports. Still, the recent turbulence in trans-Atlantic relations has some US allies rethinking their plans to buy more US-made fighter jets and weapons systems.

“Reliable and predictable orders should go to European manufacturers whenever possible,” Merz said.

This uncertainty extends to space, where it is most apparent in the launch industry. SpaceX, founded and led by Trump ally Elon Musk, dominates the global commercial launch business. European governments have repeatedly turned to SpaceX to launch multiple defense and scientific satellites over the last several years, while Europe encountered delays with its homegrown Ariane 6 and Vega rockets.

Until 2022, Europe and Russia jointly operated Soyuz rockets from the Guiana Space Center in South America to deploy government and commercial payloads to orbit. The partnership ended with Russia’s invasion of Ukraine.

Europe’s flagship Ariane 5 rocket retired in 2023, a year before its replacement—the Ariane 6—debuted on its first test flight from the Guiana Space Center. The first operational flight of the Ariane 6 delivered a French military spy satellite to orbit March 6. The smaller Vega C rocket successfully launched in December, two years after officials grounded the vehicle due to an in-flight failure.

ESA funded development of the Ariane 6 and Vega C in partnership with ArianeGroup, a joint venture between Airbus and Safran, and the Italian defense contractor Avio.

For the moment, Europe’s launcher program is back on track to provide autonomous access to space, a capability European officials consider a strategic imperative. Philippe Baptiste, France’s minister for research and higher education, said after the Ariane 6 flight earlier this month that the launch was “proof” of European space sovereignty.

“The return of Donald Trump to the White House, with Elon Musk at his side, already has significant consequences on our research partnerships, on our commercial partnerships,” Baptiste said in his remarkably pointed prepared remarks. “If we want to maintain our independence, ensure our security, and preserve our sovereignty, we must equip ourselves with the means for strategic autonomy, and space is an essential part of this.”

The problem? Ariane 6 and Vega C are costly, lack a path to reusability, and aren’t geared to match SpaceX’s blistering launch cadence. If Europe wants autonomous access to space, European taxpayers will have to pay a premium. Isar’s Spectrum also isn’t reusable, but European officials hope competition from new startups will produce fresh launch options, and perhaps stimulate an inspired response from Europe’s entrenched launch companies.

“In today’s geopolitical climate, our first test flight is about much more than a rocket launch: Space is one of the most critical platforms for our security, resilience, and technological advancement,” Metzler said. “In the next days, Isar Aerospace will lay the foundations to regain much needed independent and competitive access to space from Europe.”

Tolker-Nielsen, in charge of ESA’s space transportation division, said this is the first of many steps for Europe to develop a thriving commercial launch sector.

“This launch is a milestone, which is very important,” he said. “It’s the first conclusion of all this work, so I will be looking carefully on that. I cross my fingers that it goes well.”

Trump White House drops diversity plan for Moon landing it created back in 2019

That was then. NASA’s landing page for the First Woman comic series, where young readers could download or listen to the comic, no longer exists. Callie and her crew survived the airless, radiation-bathed surface of the Moon, only to be wiped out by President Trump’s Diversity, Equity, and Inclusion executive order, signed two months ago.

Another casualty is the “first woman” language within the Artemis Program. For years, NASA’s main Artemis page, an archived version of which is linked here, included the following language: “With the Artemis campaign, NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before.”

Artemis website changes

The current landing page for the Artemis program has excised this paragraph. It is not clear how recently the change was made. It was first noticed by British science journalist Oliver Morton.

The removal is perhaps more striking than Callie’s downfall since it was the first Trump administration that both created Artemis and highlighted its differences from Apollo by stating that the Artemis III lunar landing would fly the first woman and person of color to the lunar surface.

For its part, NASA says it is simply complying with the White House executive order by making the changes.

“In keeping with the President’s Executive Order, we’re updating our language regarding plans to send crew to the lunar surface as part of NASA’s Artemis campaign,” an agency spokesperson said. “We look forward to learning more from about the Trump Administration’s plans for our agency and expanding exploration at the Moon and Mars for the benefit of all.”

The nominal date for the Artemis III landing is 2027, but few in the industry expect NASA to be able to hold to that date. With further delays likely, the space agency will probably not name a crew anytime soon.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The ax has become an important part of the Space Force’s arsenal

“All those traditional primes opted out of this event, every single one,” Hammett said. “We’re cultivating an A-team who’s willing to work with us, who’s hungry, who wants to bring affordability and speed, and it’s not the existing industry base.”

Hammett’s office didn’t set out to banish the big defense contractors. Simply put, he said they haven’t performed or aren’t interested in going in the direction Space RCO wants to go.

“I’ve terminated 11 major contracts in less than three years,” Hammett said. “Eighty-five percent of those were with traditional defense primes.” Most of these programs are classified, so it doesn’t become news when a contract is canceled.

“We try to fix the programs,” Hammett said. “We work with the performers, but if they can’t get right, and if we have program baselines where they’re now exceeding it by 100 percent in cost or schedule… we’re going to fire them and start again.”

At the same time, venture-backed companies seem to emerge every day from the ether of Silicon Valley or one of the nation’s other tech corridors.

“There’s a lot of opportunity to bring other performers into the portfolio, but there are lots of barriers,” Hammett said. One of those barriers is that leadership at many startups don’t have a security clearance. Many small companies don’t use the certified accounting systems the government usually requires for federal contracts. 

“You have to be willing to modify your approach, your acquisition strategies, those types of things, so I have directed my team to open the aperture, to find the A-team, wherever the A-team lives, because it doesn’t seem to be in our current portfolio,” Hammett said.

There’s still a place for the Pentagon’s incumbent contractors, according to Hammett. Small companies like the ones at Space RCO’s pitch lack the national, or even global, footprint to execute the military’s most expensive programs.

“We’re trying to build the first of something new, different, at a price point that we can accept,” Hammett said. “That’s what these types of companies are trying to do. And we’re not having to pay the lion’s share of the cost for that because VC [venture capital] firms and others are kick-starting them.”

Executives at Lockheed Martin, Northrop Grumman, Boeing, and other traditional defense companies have become warier of bidding on government programs, especially fixed-price contracts where financial risk is transferred from the government to the contractor.

The CEO of L3Harris, another established defense contractor, said in 2023 that his company has also declined to bid on fixed-price development contracts. L3Harris leads development of a software system called ATLAS to manage data from a network of sensors tracking rocket launches and objects in orbit. The program is over budget and was supposed to be ready for action in 2022, but it still isn’t operational.

RTX is in charge of another troubled military space program. The Next-Generation Operational Control System, known as OCX, is designed to allow military forces, including airplanes, ships, and ground vehicles, to access a jam-resistant GPS signal that satellites have been beaming from space since 2005. Twenty years later, the military’s weapons systems still haven’t widely adopted this M-code signal because of OCX delays.

Both programs are managed by Space Systems Command, the unit that has traditionally been responsible for buying hardware and software for military space programs. SSC, too, hasn’t shied away recently from taking the hatchet to some problem projects. Last year, SSC confirmed it kicked RTX off a program to develop three next-generation missile warning satellites because it was over budget, behind schedule, and faced “unresolved design challenges.”

Can NASA remain nonpartisan when basic spaceflight truths are shredded?

It looked like the final scene of a movie, the denouement of a long adventure in which the good guys finally prevail. Azure skies and brilliant blue seas provided a perfect backdrop on Tuesday evening as a spacecraft carrying four people neared the planet’s surface.

“Just breathtaking views of a calm, glass-like ocean off the coast of Tallahassee, Florida,” commented Sandra Jones, a NASA spokesperson, during the webcast co-hosted by the space agency and SpaceX, whose Dragon vehicle returned the four astronauts from orbit.

A drone near the landing site captured incredible images of Crew Dragon Freedom as it slowly descended beneath four parachutes. Most of NASA’s astronauts today, outside of the small community of spaceflight devotees, are relatively anonymous. But not two of the passengers inside Freedom, Butch Wilmore and Suni Williams. After nine months of travails, 286 days to be precise, they were finally coming home.

Dragon continued its stately descent, falling to 400 meters, then 300, and then 200 above the ocean.

Kate Tice, an engineer from SpaceX on the webcast, noted that touchdown was imminent. “We’re going to stand by for splashdown located in the Gulf of America,” she said.

Ah, yes. The Gulf of America.

This is why we can’t have nice things.

A throne of lies

For those of us who have closely followed the story of Wilmore and Williams over the last nine months—and Ars Technica has had its share of exclusive stories about this long and strange saga—the final weeks before the landing have seen it take a disturbing turn.

Here’s the secret to how Firefly was able to nail its first lunar landing

Firefly Aerospace’s Blue Ghost science station accomplished a lot on the Moon in the last two weeks. Among other things, its instruments drilled into the Moon’s surface, tested an extraterrestrial vacuum cleaner, and showed that future missions could use GPS navigation signals to navigate on the lunar surface.

These are all important achievements, gathering data that could shed light on the Moon’s formation and evolution, demonstrating new ways of collecting samples on other planets, and revealing the remarkable reach of the US military’s GPS satellite network.

But the pièce de résistance for Firefly’s first Moon mission might be the daily dose of imagery that streamed down from the Blue Ghost spacecraft. A suite of cameras recorded the cloud of dust created as the lander’s engine plume blew away the uppermost layer of lunar soil as it touched down March 2 in Mare Crisium, or the Sea of Crises. This location is in a flat basin situated on the upper right quadrant of the side of the Moon always facing the Earth.

Other images from Firefly’s lander showed the craft shooting tethered electrodes out onto the lunar surface, like a baseball outfielder trying to throw out a runner at home plate. Firefly’s cameras also showed the lander’s drill as it began to probe several meters into the Moon’s crust.

The first Blue Ghost mission is part of NASA’s Commercial Lunar Payload Services (CLPS) program established in 2018 to partner with US companies for cargo transportation to the Moon. Firefly is one of 13 companies eligible to compete for CLPS missions, precursors to future astronaut landings on the Moon under NASA’s Artemis program.

Now, Firefly finds itself at the top of the pack of firms seeking to gain a foothold at the Moon.

Blue Ghost landed just after sunrise at Mare Crisium, an event shown in the blow video captured with four cameras mounted on the lander to observe how its engine plume interacted with loose soil on the lunar surface. The information will be useful as NASA plans to land astronauts on the Moon in the coming years.

“Although the data is still preliminary, the 3,000-plus images we captured appear to contain exactly the type of information we were hoping for in order to better understand plume-surface interaction and learn how to accurately model the phenomenon based on the number, size, thrust and configuration of the engines,” said Rob Maddock, project manager for NASA’s SCALPSS experiment.

One of the vehicle’s payloads, named Lunar PlanetVac, dropped from the bottom of the lander and released a blast of gas to blow fine-grained lunar soil into a collection chamber for sieving. Provided by a company named Honeybee Robotics, this device could be used as a cheaper alternative to other sample collection methods, such as robotic arms, on future planetary science missions.

After two weeks of pioneering work, the Blue Ghost lander fell into darkness Sunday when the Sun sank below the horizon, robbing it of solar power and plunging temperatures below minus 200° Fahrenheit (148°Celcius). The spacecraft’s internal electronics likely won’t survive the two-week-long lunar night.

A precoded message from Blue Ghost marked the moment Sunday afternoon, signaling a transition to “monument mode.”

“Goodnight friends,” Blue Ghost radioed Firefly’s mission control center in Central Texas. “After exchanging our final bits of data, I will hold vigil in this spot in Mare Crisium to watch humanity’s continued journey to the stars. Here, I will outlast your mightiest rivers, your tallest mountains, and perhaps even your species as we know it.”

Blue Ghost’s legacy is now secure as the first fully successful commercial lunar lander. Its two-week mission was perhaps just as remarkable for what didn’t happen as it was for what did. The spacecraft encountered no significant problems on its transit to the Moon, its final descent, or during surface operations.

One of the few surprises of the mission was that the lander got hotter a little sooner than engineers predicted. At lunar noon, when the Sun is highest in the sky, temperatures can soar to 250° F (121° C).

“We started noticing that the lander was getting hotter than we expected, and we couldn’t really figure out why, because it was a little early for lunar noon,” Ray Allensworth, Firefly’s spacecraft program director, told Ars. “So we went back and started evaluating and realized that the crater that we landed next to was actually reflecting a really significant amount of heat. So we went back and we updated our thermal models, incorporated that crater into it, and it matched the environment we were seeing.”

Early Friday morning, the Blue Ghost spacecraft captured the first high-definition views of a total solar eclipse from the Moon. At the same time that skywatchers on Earth were looking up to see the Moon turn an eerie blood red, Firefly’s cameras were looking back at us as the Sun, Earth, and Moon moved into alignment and darkness fell at Mare Crisium.

Diamond ring

The eclipse was a bonus for Firefly. It just happened to occur during the spacecraft’s two-week mission at the Moon, the timing of which was dependent on numerous factors, ranging from the readiness of the Blue Ghost lander to weather conditions at its launch site in Florida.

“We weren’t actually planning to have an eclipse until a few months prior to our launch, when we started evaluating and realizing that an eclipse was happening right before lunar sunset,” Allensworth said. “So luckily, that gave us some time to work some procedures and basically set up what we wanted to take images of, what cameras we wanted to run.”

The extra work paid off. Firefly released an image Friday showing a glint of sunlight reaching around the curvature of the Earth, some 250,000 miles (402,000 kilometers) away. This phenomenon is known as the “diamond ring” and is a subject of pursuit for many eclipse chasers, who travel to far-flung locations for a few minutes of totality.

The Blue Ghost spacecraft, named for a species of firefly, took eclipse chasing to new heights. Not only did it see the Earth block the Sun from an unexplored location on the Moon, but the lander fell into shadow for 2 hours and 16 minutes, about 18 times longer than the longest possible total solar eclipse on the Earth.

The eclipse presented challenges for Firefly’s engineers monitoring the mission from Texas. Temperatures at the spacecraft’s airless landing site plummeted as darkness took hold, creating what Allensworth called a “pseudo lunar night.”

“We were seeing those temperatures rapidly start dropping,” Allensworth said Friday. “So it was kind of an interesting game of to play with the hardware to keep everything in its temperature bounds but also still powered on and capturing data.”

Shaping up

Using navigation cameras and autonomous guidance algorithms, the spacecraft detected potential hazards at its original landing site and diverted to a safer location more than 230 feet (70 meters) away, according to Allensworth.

Finally happy with the terrain below, Blue Ghost’s computer sent the command for landing, powered by eight thrusters pulsing in rapid succession to control the craft’s descent rate. The landing was gentler than engineers anticipated, coming down at less than 2.2 mph (1 meter per second).

According to preliminary data, Blue Ghost settled in a location just outside of its 330-foot (100-meter) target landing ellipse, probably due to the last-minute divert maneuvers ordered by the vehicle’s hazard avoidance system.

It looks like we’re slightly out of it, but it’s really OK,” Allensworth said. “NASA has told us, more than anything, that they want us to make sure we land softly… They seem comfortable where we’re at.”

Firefly originally intended to develop a spacecraft based on the design of Israel’s Beresheet lander, which was the first private mission to attempt a landing on the Moon in 2019. The spacecraft crashed, and Firefly opted to go with a new design more responsive to NASA’s requirements.

“Managing the center of gravity and the mass of the lander is most significant, and that informs a lot of how it physically takes shape,” Allensworth said. “So we did want to keep certain things in mind about that, and that really is what led to the lander being wider, shorter, broader. We have these bigger foot pads on there. All of those things were very intentional to help make the lander as stable and predictable as possible.”

These design choices must happen early in a spacecraft’s development. Landing on the Moon comes with numerous complications, including an often-uneven surface and the lack of an atmosphere, rendering parachutes useless. A lander targeting the Moon must navigate itself to a safe landing site without input from the ground.

The Odysseus, or Nova-C, lander built by Intuitive Machines snapped one of its legs and fell over on its side after arriving on the Moon last year. The altimeter on Odysseus failed, causing it to come down with too much horizontal velocity. The lander returned some scientific data from the Moon and qualified as a partial success. The spacecraft couldn’t recharge its batteries after landing on its side, and Odysseus shut down a few days after landing.

The second mission by Intuitive Machines reached the Moon on March 6, but it suffered the same fate. After tipping over, the Athena lander succumbed to low power within hours, preventing it from accomplishing its science mission for NASA.

The landers designed by Intuitive Machines are tall and skinny, towering more than 14 feet (4.3 meters) tall with a width of about 5.2 feet (1.6 meters). The Blue Ghost vehicle is short and squatty in shape—about 6.6 feet tall and 11.5 feet wide (2-by-3.5 meters). Firefly’s approach requires fewer landing legs than Intuitive Machines—four instead of six.

Steve Altemus, co-founder and CEO of Intuitive Machines, defended the design of his company’s lander in a press briefing after the second lunar landing tip-over earlier this month. The Nova-C lander isn’t too top-heavy for a safe landing because most of its cargo attaches to the bottom of the spacecraft, and for now, Altemus said Intuitive Machines is not considering a redesign.

Intuitive Machines stacked its two fuel and oxidizer tanks on top of each other, resulting in a taller vehicle. The Nova-C vehicle uses super-cold methane and liquid oxygen propellants, enabling a fast journey to the Moon over just a few days. The four propellant tanks on Blue Ghost are arranged in a diagonal configuration, with two containing hydrazine fuel and two holding an oxidizer called nitrogen tetroxide. Firefly’s Blue Ghost took about six weeks to travel from launch until landing.

The design trade-off means Firefly’s lander is heavier, with four tanks instead of two, according to Will Coogan, Blue Ghost’s chief engineer at Firefly. By going with a stockier lander design, Firefly needed to install four tanks because the spacecraft’s fuel and oxidizer have different densities. If Firefly went with just two tanks side-by-side, the spacecraft’s center of mass would change continually as it burns propellant during the final descent to the Moon, creating an unnecessary problem for the lander’s guidance, navigation, and control system to overcome.

“You want to avoid that,” Coogan told Ars before Blue Ghost’s launch. “What you can do is you can either get four tanks and have fuel and oxidizer at diagonal angles, and then you’re always centered, or you can stay with two tanks, and you can stack them.”

The four landing legs on the Blue Ghost vehicle have shock-absorbing feet, with bowl-shaped pads able to bend if the lander comes down on a rock or a slope.

“If we did come in a little bit faster, we needed the legs to be able to take that, so we tested the legs really significantly on the ground,” Allensworth said. “We basically loaded them up on a makeshift weight bench at different angles and slammed it into the ground, slammed it into concrete, slammed it into regular simulant rocks, boulders, at different angles to really characterize what the legs could do.

“It’s actually really funny, because one of the edge cases that we didn’t test is if we came down very lightly, with almost no acceleration,” she said. “And that was the case that the lander landed in. I was joking with our structural engineer that he wasted all his time.”

Proof positive

Firefly delivered 10 NASA-sponsored science and technology demonstration experiments to the lunar surface, operating under contract with NASA’s CLPS program. CLPS builds on the commercial, service-based business model of NASA’s commercial cargo and crew program for transportation to the International Space Station.

NASA officials knew this approach was risky. The last landing on the Moon by a US spacecraft was the last Apollo mission in 1972, and most of the companies involved in CLPS are less than 20 years old, with little experience in deep space missions.

A Pittsburgh company named Astrobotic failed to reach the Moon on its first attempt in January 2024. The next month, Houston-based Intuitive Machines landed its Nova-C spacecraft on the lunar surface, but it tipped over after one of its legs snapped at the moment of touchdown.

Firefly, based in Cedar Park, Texas, was the third company to try a landing. Originally established as a rocket developer, Firefly signed up to be a CLPS provider and won a $101 million contract with NASA in 2021 to transport a government-funded science package to the Moon. NASA’s instruments aboard the Blue Ghost lander cost about $44 million.

The successful landing of Firefly’s Blue Ghost earlier this month buoyed NASA’s expectations for CLPS. “Overall, it’s been a fabulous, wonderful proof positive that the CLPS model does work,” said Brad Bailey, assistant deputy associate administrator for exploration in NASA’s Science Mission Directorate.

NASA has seven more CLPS missions on contract. The next could launch as soon as August when Blue Origin plans to send its first Blue Moon lander to the Moon. NASA has booked two more Blue Ghost missions with Firefly and two more landing attempts with Intuitive Machines, plus one more flight by Astrobotic and one lander from Draper Laboratory.

To avoid the Panama Canal, Relativity Space may move some operations to Texas

Although Baytown does not have any historical affinity with aerospace, its location on the water offers far more straightforward access to Relativity’s test facilities in Mississippi and its launch site in Florida. There are other benefits. The cost of living in the region is far lower than Southern California, and due to the location of Johnson Space Center just 20 miles away, there is a reservoir of space talent in the region.

A spokesperson for Relativity Space did not confirm the move.

“As we scale Terran R production to meet growing customer demand, we are exploring options to expand our manufacturing capabilities,” the spokesperson said. “Our focus is on ensuring we have the right footprint to achieve the production cadence required to serve our customers.”

Texas space is on the rise

For logistics and other reasons, Relativity has been evaluating locations across several states that border the Gulf of Mexico, including Texas, over recent years, multiple sources said. The company is expected to continue operating its large “Wormhole” factory in Long Beach, California, which is more than 1 million square feet in size. A second factory in Texas would likely be used to build propellant tanks and assemble stages for testing in Mississippi and launch in Florida.

The addition of a second factory in Texas would underscore the investment to which Schmidt appears committed to making Relativity a major player in US launch.

It is unclear whether state or local officials have provided any incentives to Relativity for relocating a significant chunk of its manufacturing operations to Texas. Last year the state legislature created the Texas Space Commission and provided $350 million in funding to support commercial space operations. In February the commission awarded the first of these grants, valued at $47.7 million, to five companies with Texas-based operations: Starlab Space, Intuitive Machines, Firefly Aerospace, SpaceX, and Blue Origin.

A leading figure behind the commission is State Rep. Greg Bonnen, whose district includes Johnson Space Center. Bonnen has signaled that the commission is a long-term project by the state to ensure its economic prosperity in the 21st century by continuing to grow existing businesses in Texas, but also to attract new companies to the state.

SpaceX and Firefly already manufacture rockets in Texas. Adding Relativity Space would be a significant coup for a state that, only a decade ago, was known primarily in space for being the home of NASA’s human spaceflight activities.

crew-10-launches,-finally-clearing-the-way-for-butch-and-suni-to-fly-home

Crew-10 launches, finally clearing the way for Butch and Suni to fly home

A Falcon 9 rocket launched four astronauts safely into orbit on Friday evening, marking the official beginning of the Crew-10 mission to the International Space Station.

Although any crew launch into orbit is notable, this mission comes with an added bit of importance as its success clears the way for two NASA astronauts, Butch Wilmore and Suni Williams, to finally return home from space after a saga spanning nine months.

Friday’s launch came two days after an initial attempt was scrubbed on Wednesday evening. This was due to a hydraulic issue with the ground systems that handle the Falcon 9 rocket at Launch Complex 39A in Florida.

There were no technical issues on Friday, and with clear skies NASA astronauts Anne McClain and Nichole Ayers, Japanese astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov rocketed smoothly into orbit.

If all goes well, the Crew Dragon spacecraft carrying the four astronauts will dock with the space station at 11: 30 pm ET on Saturday. They will spend about six months there.

A long, strange trip

Following their arrival at the space station, the members of Crew-10 will participate in a handover ceremony with the four astronauts of Crew-9, which includes Wilmore and Williams. This will clear the members of Crew 9 for departure from the station as early as next Wednesday, March 19, pending good weather in the waters surrounding Florida for splashdown of Dragon.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Athena landed in a dark crater where the temperature was minus 280° F

The Athena spacecraft was not exactly flying blind as it approached the lunar surface one week ago. The software on board did a credible job of recognizing nearby craters, even with elongated shadows over the terrain. However, the lander’s altimeter had failed.

So while Athena knew where it was relative to the surface of the Moon, the lander did not know how far it was above the surface.

An important detail, that. As a result, the privately built spacecraft struck the lunar surface on a plateau, toppled over, and began to skid across the surface. As it did so, the lander rotated at least once or twice before coming to a stop in a small, shadowed crater.

“The landing was kind of like sliding into second base,” Steve Altemus, chief executive officer of Intuitive Machines, which built the lander, said in an interview Thursday.

Cold and lonely

It has been a busy and tiring week for the chief of a company that seeks to help lead the development of a lunar economy. Expectations were high for this, the company’s second lunar landing attempt after its Odysseus vehicle became the first private spacecraft to ever make a soft landing on the Moon, last year, before toppling over.

In some ways, this mission was even more disappointing. Because Athena skidded across the lunar surface, it dredged up regolith. When it came to a stop, some of this material was blown up into the solar panels—already in a sub-optimal location on its side. The spacecraft’s power reserves, therefore, were limited. Almost immediately, the team at Intuitive Machines knew their spacecraft was dying.

“We knew we had slid into a slightly shadowed crater, and the temperature was very cold,” Altemus said. “The solar arrays had regolith on them, and they weren’t charging, the ones pointing up, enough to give us sufficient power to power the heaters to keep it warm enough to survive.”
