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, one of the co-founders, 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 the 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 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 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.”

Rocket Report: Falcon 9 may smash reuse record; Relativity roving to Texas?


All the news that’s fit to lift

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.”

trump-white-house-drops-diversity-plan-for-moon-landing-it-created-back-in-2019

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.

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 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.

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

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.

athena-landed-in-a-dark-crater-where-the-temperature-was-minus-280°-f

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.”

What happens when DEI becomes DOA in the aerospace industry?

As part of the executive order, US companies with federal contracts and grants must certify that they no longer have any DEI hiring practices. Preferentially hiring some interns from a pool that includes women or minorities is such a practice. Effectively, then, any private aerospace company that receives federal funding, or intends to one day, would likely be barred under the executive order from engaging with these kinds of fellowships in the future.

US companies are scrambling to determine how best to comply with the executive order in many ways, said Emily Calandrelli, an engineer and prominent science communicator. After the order went into effect, some large defense contractor companies, including Lockheed Martin and RTX (formerly Raytheon) went so far as to cancel internal employee resource groups, including everything from group chats to meetings among women at the company that served to foster a sense of community. When Calandrelli asked Lockheed about this decision, the company confirmed it had “paused” these resource group activities to “align with the new executive order.”

An unwelcoming environment

For women and minorities, Calandrelli said, this creates an unwelcoming environment.

“You want to go where you are celebrated and wanted, not where you are tolerated,” she said. “That sense of belonging is going to take a hit. It’s going to be harder to recruit women and keep women.”

This is not just a problem for women and minorities, but for everyone, Calandrelli said. The aerospace industry is competing with others for top engineering talent. Prospective engineers who feel unwanted in aerospace, as well as women and minorities working for space companies today, may find the salary and environment more welcoming at Apple or Google or elsewhere in the tech industry. That’s a problem for the US Space Force and other areas of the government seeking to ensure the US space industry retains its lead in satellite technology, launch, communications and other aspects of space that touch every part of life on Earth.

No, that’s not a cosmic cone of shame—it’s NASA’s newest space telescope


A filter for the Universe

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.

The mission launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California at 8: 10 pm local time (11: 10 pm EDT) Tuesday. Less than 45 minutes later, the Falcon 9’s upper stage released SPHEREx into a polar orbit at an altitude of roughly 420 miles (675 kilometers). Ground controllers received the first signals from the spacecraft, confirming its health after reaching space.

As soon as next month, once engineers verify the observatory is ready, SPHEREx will begin a two-year science mission surveying the sky in 102 colors invisible to the human eye. The observatory’s infrared detectors will collect data on the chemical composition of asteroids, hazy star-forming clouds, and faraway galaxies.

“SPHEREx is going to produce an enormous three-dimensional map of the entire night sky, and with this immense and novel dataset, we’re going to address some of the most fundamental questions in astrophysics,” said Phil Korngut, the mission’s instrument scientist at Caltech.

“Using a technique called linear variable filter spectroscopy, we’re going to produce 102 maps in 102 wavelengths every six months, and our baseline mission is to do this four time over the course of two years,” Korngut said.

Boiling it down

The acronym for the SPHEREx mission is a mouthful—it stands for the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. Scientists sum up the $488 million mission by saying it seeks answers to three basic questions:

• How did the Universe begin?

• How did galaxies begin?

• What are the conditions for life outside the Solar System?

While it’s possible to sum up these objectives in an elevator pitch, the details touch on esoteric topics like cosmic inflation, quantum physics, and the flatness of spacetime. Philosophically, these questions are existential. SPHEREx will try to punch above its weight.

Built by BAE Systems, SPHEREx is about the size of a subcompact car, and it lacks the power and resolution of a flagship observatory like the James Webb Space Telescope. Webb’s primary mirror spans more than 21 feet (6.5 meters) across, while SPHEREx’s primary mirror has an effective diameter of just 7.9 inches (20 centimeters), comparable to a consumer-grade backyard telescope.

But NASA’s newest space telescope has a few advantages. While Webb is designed to peer deep into small slivers of the sky, SPHEREx’s wider field of view will observe the sky in all directions. Like its name might suggest, SPHEREx will capture a spherical view of the cosmos. Color filters overlay the instrument’s detector array to separate light coming into the telescope into its component wavelengths, a process known as spectroscopy. NASA says SPHEREx’s unique design allows it to conduct infrared spectroscopy on hundreds of thousands of objects simultaneously, and more than 600 exposures per day.

“SPHEREx is a testament to doing big science with a small telescope,” said Beth Fabinsky, the mission’s project manager at NASA’s Jet Propulsion Laboratory in California.

Because SPHEREx orbits hundreds of miles above the Earth, the telescope flies above the discernible atmosphere, which can absorb faint thermal energy coming from distant astronomical sources. Its detectors must be cold, below minus 360 degrees Fahrenheit, or 55 Kelvin, or the the telescope would be blinded by its own light. This is the reason the spacecraft has such an unusual look.

Many past infrared telescopes used cryogenic coolant to chill their detectors, but this is a finite resource that gradually boils off in space, limiting mission lifetimes. Webb uses a complicated tennis court-sized sunshield to block heat and light from the Sun from its infrared instruments. Engineers came up with a simpler solution for SPHEREx.

Three concentric photon shields extend from the top of the spacecraft to insulate the telescope’s optics and detectors from light from the Sun and the Earth. This design requires no moving parts, boosting the mission’s reliability and longevity. The photon shields look like an Elizabethan collar. Pet owners may know it as the “cone of shame” given to animals after surgeries.

For SPHEREx, this cone is an enabler, allowing astronomers to map hundreds of millions of galaxies to study inflation, a cosmological theory that suggests the Universe underwent a mind-boggling expansion just after the Big Bang nearly 13.8 billion years ago. Through the process of inflation, the Universe grew a “trillion-trillion-fold” in a fraction of a second, Korngut said.

The theory suggests inflation left behind the blueprint for the largest-scale structures of the Universe, called the cosmic web. Inflation “expanded tiny fluctuations, smaller than an atom, to enormous cosmological scales that we see today, traced out by galaxies and clusters of galaxies,” said Jamie Bock, a cosmologist at Caltech who leads the SPHEREx science team.

“Even though inflation (theory) was invented in the 1980s, it’s been tested over the intervening decades and has been consistent with the data,” Bock said. “While we have this general picture, we still don’t know what drove inflation, why it happened. So what SPHEREx will do will test certain models of inflation by tracing out the three dimensions, hundreds of millions of galaxies, over the entire sky. And those galaxies trace out the initial fluctuations set up by inflation.”

SPHEREx’s telescope will also collect the combined light emitted by all galaxies, all the way back to the cosmic dawn, when the first stars and galaxies shined through the foggy aftermath of the Big Bang. Scientists believe star formation peaked in the Universe some 10 billion years ago, but their understanding of cosmic history is based on observations of a relatively small population of galaxies.

“SPHEREx, with its small telescope, is going to address this subject in a novel way,” Bock said. “Instead of really counting, very deeply, individual galaxies, SPHEREx is going to look at the total glow produced by all galaxies. This cosmological glow captures all light emitted over cosmic history from galaxies, as well as anything else that emits light. So it’s a very different way of looking at the Universe, and in particular, that first stage of star and galaxy formation must also be in this cosmic glow.”

Bock and his science team will match the aggregate data from SPHEREx with what they know about the Universe’s early galaxies from missions like Webb and the Hubble Space Telescope. “We can compare to counts that have been built up with large telescopes and see if we’ve missed any sources of light,” Bock said.

Closer to home

In our own galaxy, SPHEREx will use its infrared sensitivity to investigate the origins and abundance of water and ice in molecular clouds, the precursors to alien solar systems where gas and dust collapse to form stars and planets.

“We think that most of the water and ice in the universe is in places like this,” said Rachel Akeson, SPHEREx science data center lead at Caltech. “It’s also likely that the water in Earth’s oceans originated in the molecular cloud. So how will SPHEREx map the ice in our galaxy? While other space telescopes have found reservoirs of water in hundreds of locations, SPHEREx observations of our galaxy will give us more than 9 million targets, a much bigger sample than we have now.”

As the telescope scans across these millions of targets, its detectors will make measurements of each point in the sky in 102 infrared wavelengths. With the help of spectroscopy, SPHEREx will measure how much water is bound up in these star-forming clouds.

“Knowing the water content around the galaxy is a clue to how many locations could potentially host life,” Akeson said.

All-sky surveys like SPHEREx’s often turn up surprises because they ingest immense amounts of data. They leave behind enduring legacies by building up catalogs of galaxies and stars. Astronomers use these archives to plan follow-up observations by more powerful telescopes like Webb and Hubble, or with future observatories employing technologies unavailable today.

As it pans across the sky observing distant galaxies, SPHEREx’s telescope will also catch glimpses of targets within our own Solar System. These include planets and thousands of asteroids, comets, icy worlds beyond Pluto, and interstellar objects that occasionally transit through the Solar System. SPHEREx sill measure water, iron, carbon dioxide, and multiple types of ices (water, methane, nitrogen, ammonia, and others) on the surface of these worlds closer to home.

Finding savings where possible

A second NASA mission hitched a ride to space with SPHEREx, deploying into a similar orbit a few minutes after the Falcon 9 released its primary payload.

This secondary mission, called PUNCH, consists of four suitcase-sized satellites that will study the solar corona, or outer atmosphere, a volatile sheath of super-heated gas extending millions of miles from the Sun’s surface. NASA expects PUNCH’s $150 million mission will reveal information about how the corona generates the solar wind, a continuous stream of charged particles streaming out in all directions from the Sun.

There are tangible reasons to study the solar wind. These particles travel through space at speeds close to 1 million mph, and upon reaching Earth, interact with our planet’s magnetic field. Bursts of energy erupting from the Sun, like solar flares, can generate shocks in the solar wind current, leading to higher risks for geomagnetic storms. These have a range of effects on the Earth, ranging from colorful but benign auroras to disruptions to satellite operations, navigation, and communication.

Other NASA spacecraft have zoomed in to observe second-by-second changes in the Sun’s atmosphere, and a fleet of sentinels closer to Earth measure the solar wind after it has traveled through space for three days. PUNCH will combine the imaging capacities of four small satellites to create a single “virtual instrument” with a view broad enough to monitor the solar wind as it leaves the Sun and courses farther into the Solar System.

Hailing a ride to space is not as simple as opening up Uber on your phone, but sharing rides offers a more cost-effective way to launch small satellites like PUNCH. SpaceX regularly launches rideshare flights, called Transporter missions, on its Falcon 9 rocket, sometimes with more than 100 satellites on a single launch going to a standard orbit. Missions like SPHEREx and PUNCH aren’t usually a good fit for SpaceX’s Transporter missions because they have more stringent demands for cleanliness and must launch into bespoke orbits to achieve their science goals.

Matching SPHEREx and PUNCH to the same rocket required both missions to go to the same orbit, and be ready for launch at the same time. That’s a luxury not often available to NASA’s mission planners, but where possible, the agency wants to take advantage of rideshare opportunities.

Launching the PUNCH mission on its own dedicated rocket would have likely cost at least $15 million. This is the approximate price of a mission on Firefly Aerospace’s Alpha rocket, the cheapest US launcher with the muscle to lift the PUNCH satellites into orbit.

“This is a real change in how we do business,” said Mark Clampin, the acting deputy administrator for NASA’s Science Mission Directorate, or SMD. “It’s a new strategy that SMD is working where we can maximize the efficiency of launches by flying two payloads at once, so we maximize the science return.”

former-google-ceo-eric-schmidt-is-the-new-leader-of-relativity-space

Former Google CEO Eric Schmidt is the new leader of Relativity Space

Another Silicon Valley investor is getting into the rocket business.

Former Google chief executive Eric Schmidt has taken a controlling interest in the Long Beach, California-based Relativity Space. The New York Times first reported the change becoming official, after Schmidt told employees in an all-hands meeting on Monday.

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.

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.

“Today marks a powerful new chapter as Eric Schmidt becomes Relativity’s CEO, while also providing substantial financial backing,” Ellis wrote on the social media site X. “I know there’s no one more tenacious or passionate to propel this dream forward. We have been working together to ensure a smooth transition, and I’ll proudly continue to support the team as Co-founder and Board member.”

Terran R’s road to launch

On Monday, Relativity also released a nearly 45-minute video that outlines the development of the Terran R rocket to date and the lengths it must go to reach the launch pad. Tellingly, Ellis appears only briefly in the video, which features several other senior officials who presumably will remain with the company, including Chief Operating Officer Zach Dunn.
