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 For years, NASA’s main Artemis page, an archived version of which is linked here, included the following language: “With the Artemis campaign, NASA will land the first woman and first person of color on the Moon,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

“SPHEREx is going to produce an enormous three-dimensional map of the entire night sky.”

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.

What’s behind the recent string of failures and delays at SpaceX?


SpaceX has long had a hard-charging culture. Is it now charging too hard?

It has been an uncharacteristically messy start to the year for the world’s leading spaceflight company, SpaceX.

Let’s start with the company’s most recent delay. The latest launch date for a NASA mission to survey the sky and better understand the early evolution of the Universe comes Monday night. The launch window for this SPHEREx mission opened on February 28, but a series of problems with integrating the rocket and payloads have delayed the mission nearly two weeks.

Then there are the Falcon 9 first stage issues. Last week, a Falcon 9 rocket launched nearly two dozen Starlink satellites into low-Earth orbit. However, one of the rocket’s nine engines suffered a fuel leak during ascent. Due to a lack of oxygen in the thinning atmosphere, the fuel leak did not preclude the satellites from reaching orbit. But when the first stage returned to Earth, it caught fire after landing on a droneship, toppling over. This followed a similar issue in August, when there was a fire in the engine compartment. After nearly three years without a Falcon 9 landing failure, SpaceX had two in six months.

SpaceX has also experienced recent and recurring problems with the Falcon 9 rocket’s expendable upper stage. On February 1, a second stage deorbit burn failed after a Starlink launch. This led to propellant tanks from the stage crashing into western Poland, causing property damage but harming no one. It was the third time in six months that SpaceX had encountered an issue with the Falcon 9 second stage.

Finally, and most publicly, the company’s massive Starship has failed on its last two test flights.

Although the vehicle’s first stage performed nominally during test flights in January and March, returning safely to its launch site, the Starship upper stage exploded spectacularly in flight twice. On both occasions, a fire developed in the engine section of Starship, and the vehicle rained fiery debris trails over the Bahamas and other nearby islands. Air traffic controllers diverted or delayed dozens of commercial airline flights flying through the debris footprint.

Putting this into perspective

These issues have occurred against the backdrop of a largely successful and unprecedented launch performance.

For all of the problems described earlier, the company’s only operational payload loss was its own Starlink satellites in July 2024 due to a second stage issue. Before that, SpaceX had not lost a payload with the Falcon 9 in nearly a decade. So SpaceX has been delivering for its customers in a big way.

SpaceX has achieved a launch cadence with the Falcon 9 rocket that’s unmatched by any previous rocket—or even nation—in history. If the SPHEREx mission launches tonight, as anticipated, it would be the company’s 27th mission of this year. The rest of the world combined, including China and its growing space activity, will have a total of 19 orbital launch attempts.

In the United States, SpaceX’s historic launch competitor, United Launch Alliance, has yet to fly a single rocket this year. In fact, the company has not launched in 156 days. During that time, SpaceX has launched 64 Falcon 9 rockets. So yes, SpaceX has had some technical issues. But it is also flying circles around its competition.

The recent failures are also unlikely to jeopardize, at least in the near term, SpaceX’s globally dominant position. The company provides the Western world’s only human access to orbit, and that’s unlikely to change for a while. SpaceX launches the vast majority of NASA’s science missions, and until United Launch Alliance’s Vulcan rocket becomes certified, it remains the US military’s only way to get larger payloads into space. The company also operates a global Internet network with more than 5 million users, and that number is growing rapidly.

All the same, these recent failures may be telling us something about SpaceX.

What is causing this

Without being inside SpaceX, it is impossible to put a fine point on what precisely is happening to cause these technical issues.

Probably the most significant factor is the company’s ever-present pressure to accelerate, even while taking on more and more challenging tasks. No country or private company ever launched as many times as SpaceX did in 2024. By way of comparison, NASA launched the Space Shuttle 135 times, a comparable number to the total of Falcon 9 launches last year (132), over a 30-year period.

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.

To put it succinctly, SpaceX is balancing a lot of spinning plates, and the company’s leadership is telling its employees to spin the plates faster and faster.

Multiple sources have indicated that the Starship engineering team was under immense pressure after the January 16 failure to identify the cause of a “harmonic response” in the vehicle’s upper stage that contributed to its loss. The goal was to find and fix the problem as quickly as possible.

Let’s step back and appreciate that Starship is an experimental system, by far the largest and most powerful rocket ever flown, and it catastrophically failed in January. During a span of just seven weeks, the Starship team had to study the failure, address any problems, and prepare new hardware.

How much of this is on SpaceX founder Elon Musk? Some have suggested his deep involvement in the 2024 presidential election, oversight of the Department of Government Efficiency, excessive social media activity, and more—like picking fights with US senators— have distracted him from the problems of SpaceX. And there’s no doubt that Musk has been focused on things other than SpaceX for the last half-year or longer.

However, in Musk’s absence, he has capable lieutenants such as Mark Juncosa leading the way. SpaceX has long had a hard-charging culture instilled by Musk since the founding of the company. Musk’s modus operandi is to push his teams to reach some ambitious goal, and when they do, he sets a new, even more audacious target. It may be not so much Musk’s absence that is causing these issues but rather the company’s relentless culture.

It seems possible that, at least for now, SpaceX has reached the speed limit for commercial spaceflight. When you’re launching 150 times a year and building two second stages a week, it’s hard to escape the possibility that some details are slipping through the cracks. And it’s not just the launches. SpaceX is operating a constellation of more than 7,000 satellites, flying humans into space regularly, and developing an unprecedented rocket like Starship.

The recent failures may be signs of cracks in the foundation.

What are the implications

So far, the consequences of these failures have not been lethal. But space remains a difficult, hazardous game. Reentering debris from a Falcon 9 upper stage could have struck someone in Poland. God forbid, a second stage could fail early in a crewed mission.

The risks of serious problems with Starlink should not be understated, either. There have been unconfirmed rumors in recent months of near misses between Starlink satellites and objects in low-Earth orbit. Additional debris in this increasingly cluttered space would be disastrous.

To date, the Falcon 9 rocket program has not been slowed down by these issues. It’s perhaps not fully appreciated how utterly reliant NASA’s human spaceflight activities are on the Falcon 9. It currently launches the only crew-capable vehicle in Dragon. However, a Cargo version of Dragon also flies on the Falcon 9, and this is NASA’s only way to get scientific experiments back to Earth. And for at least the next year, the only other US cargo vehicle, Northrop Grumman’s Cygnus, also must launch on the Falcon 9.

Not just NASA, but every other space station partner outside of Russia, depends on the Falcon 9 for human spaceflight activities. The rocket must fly, and fly safely, or the West will be grounded.

With Starship, the recent failures are a significant setback. Although there will no doubt be pressure from SpaceX leadership to rapidly move forward, there appears to be a debilitating design flaw in the upgraded version of Starship. It will be important to understand and address this. Another launch before this summer seems unlikely. A third consecutive catastrophic failure would be really, really bad.

For the space agency’s Artemis program to return humans to the Moon, Starship’s problems spell more delays. Musk had already signaled in late February that a critical refueling demonstration will now not happen this year. This test is an essential milestone on the path to the Moon, and its delay all but ensures the first lunar landing will not happen in 2027 as currently envisioned.

Most likely, the back-to-back Starship failures will also cement the path forward for Artemis II and Artemis III to fly as planned, with crews flying on the Space Launch System rocket and Orion spacecraft.

As for Mars, the red planet remains in the far distance, waiting for SpaceX to address its red flags here on Earth.

After less than a day, the Athena lander is dead on the Moon

NASA expected Athena to have a reasonable chance of success. Although it landed on its side, Odysseus was generally counted as a win because it accomplished most of its tasks. Accordingly, NASA loaded a number of instruments onto the lander. Most notable among these was the PRIME-1 experiment, an ice drill to sample and analyze any ice that lies below the surface.

A dark day, but not the end

“After landing, mission controllers were able to accelerate several program and payload milestones, including NASA’s PRIME-1 suite, before the lander’s batteries depleted,” the company’s statement said. However, this likely means that the company was able to contact the instrument but not perform any meaningful scientific activities.

NASA has accepted that these commercial lunar missions are high-risk, high-reward. (Firefly’s successful landing last weekend offers an example of high rewards). It is paying the companies, on average, $100 million or less per flight. This is a fraction of what NASA would pay through a traditional procurement program. The hope is that, after surviving initial failures, companies like Intuitive Machines will learn from their mistakes and open a low-cost, reliable pathway to the lunar surface.

Even so, this failure has to be painful for NASA and Intuitive Machines. The space agency lost out on some valuable science, and Intuitive Machines has taken a step backward with this mission rather than moving forward as it had hoped to do.

Fortunately, this is unlikely to be the end for the company. NASA has committed to a third and fourth mission on Intuitive Machines’ lander, the next of which could come during the first quarter of 2026. NASA has also contracted with the company to build a small network of satellites around the Moon for communications and positioning services. So although the company’s fortunes look dark today, they are not permanently shadowed like the craters on the Moon that NASA hopes to soon explore.

White House may seek to slash NASA’s science budget by 50 percent

In many ways, NASA’s science directorate is the crown jewel of the space agency. Nearly all of the most significant achievements over the last 25 years have been delivered by the science programs: Ingenuity flying on Mars, New Horizons swooping by Pluto, images from the James Webb Space Telescope, the discovery of thousands of exoplanets, the return of samples from asteroids and comets, Cassini’s discovery of water plumes on Enceladus, a continuous robotic presence on Mars, and so much more. Even the recent lunar landings by Firefly and Intuitive Machines were funded by NASA’s science directorate.

Of NASA’s roughly $25 billion budget, however, only about 30 percent is allocated to science. For fiscal year 2024, this amounted to $7.4 billion. This spending was broken down into approximately $2.7 billion for planetary science, $2.2 billion for Earth science, $1.5 billion for astrophysics, and $800 million for heliophysics.

The proposed cuts are being driven by Russell Vought, the recently confirmed director of the White House Office of Management and Budget, which sets budget and policy priorities for a presidential administration. In some sense, the budgetary decisions should not come as a surprise, as they are consistent with what Vought proposed in a “shadow” budget for fiscal-year 2023 as part of his Center for Renewing America.

“The budget also proposes a 50 percent reduction in NASA Science programs and spending, reducing their misguided Carbon Reduction System spending and Global Climate Change programs,” Vought’s organization wrote in its report published in December 2022.

Zeroing out Earth science?

Despite Vought’s desire, however, NASA is expressly charged with studying our planet.

The congressional act that created NASA in 1958 calls for the space agency to expand human knowledge about Earth’s atmosphere and space, and the agency’s Earth observation satellites have substantially increased our understanding of this planet’s weather, changing climate, and land use.

Even if NASA’s Earth science budget were taken to zero, cutting the overall science budget in half would still dramatically reduce funding in planetary science as well as other research areas. Scientists told Ars that NASA would be forced to make difficult decisions, likely including shutting off extended missions such as the Voyager and Curiosity probes on Mars, and possibly even the Hubble Space Telescope. It might be possible to save missions in later stages of development, such as the Dragonfly probe to Saturn’s moon Titan, and the NEO Surveyor mission to search for hazardous asteroids. But it would be impossible to start meaningful new missions to explore the Solar System, potentially setting back planetary exploration a decade.
