June 5, 20254 min readThe Trump-Musk Fight Could Have Huge Consequences for U.S. Space ProgramsA vitriolic war of words between President Donald Trump and SpaceX CEO Elon Musk could have profound repercussions for the nation’s civil and military space programsBy Lee Billings edited by Dean VisserElon Musk (left) and President Donald Trump (right) seemed to be on good terms during a press briefing in the Oval Office at the White House on May 30, 2025, but the event proved to be the calm before a social media storm. Kevin Dietsch/Getty ImagesFor several hours yesterday, an explosively escalating social media confrontation between arguably the world’s richest man, Elon Musk, and the world’s most powerful, President Donald Trump, shook U.S. spaceflight to its core.The pair had been bosom-buddy allies ever since Musk’s fateful endorsement of Trump last July—an event that helped propel Trump to an electoral victory and his second presidential term. But on May 28 Musk announced his departure from his official role overseeing the U.S. DOGE Service. And on May 31 the White House announced that it was withdrawing Trump’s nomination of Musk’s close associate Jared Isaacman to lead NASA. Musk abruptly went on the attack against the Trump administration, criticizing the budget-busting One Big Beautiful Bill Act, now navigating through Congress, as “a disgusting abomination.”Things got worse from there as the blowup descended deeper into threats and insults. On June 5 Trump suggested on his own social-media platform, Truth Social, that he could terminate U.S. government contracts with Musk’s companies, such as SpaceX and Tesla. Less than an hour later, the conflict suddenly grew more personal, with Musk taking to X, the social media platform he owns, to accuse Trump—without evidence—of being incriminated by as-yet-unreleased government documents related to the illegal activities of convicted sex offender Jeffrey Epstein.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Musk upped the ante further in follow-up posts in which he endorsed a suggestion for impeaching Trump and, separately, declared in a now deleted post that because of the president’s threat, SpaceX “will begin decommissioning its Dragon spacecraft immediately.” (Some five hours after his decommissioning comment, tempers had apparently cooled enough for Musk to walk back the remark in another X post: “Ok, we won’t decommission Dragon.”)Dragon is a crucial workhorse of U.S. human spaceflight. It’s the main way NASA’s astronauts get to and from the International Space Station (ISS) and also a key component of a contract between NASA and SpaceX to safely deorbit the ISS in 2031. If Dragon were to be no longer be available, NASA would, in the near term, have to rely on either Russian Soyuz vehicles or on Boeing’s glitch-plagued Starliner spacecraft for its crew transport—and the space agency’s plans for deorbiting the ISS would essentially go back to the drawing board. More broadly, NASA uses SpaceX rockets to launch many of its science missions, and the company is contracted to ferry astronauts to and from the surface of the moon as part of the space agency’s Artemis III mission.Trump’s and Musk’s retaliatory tit for tat also raises the disconcerting possibility of disrupting other SpaceX-centric parts of U.S. space plans, many of which are seen as critical for national security. Thanks to its wildly successful reusable Falcon 9 and Falcon Heavy rockets, the company presently provides the vast majority of space launches for the Department of Defense. And SpaceX’s constellation of more than 7,000 Starlink communications satellites has become vitally important to war fighters in the ongoing conflict between Russia and U.S.-allied Ukraine. SpaceX is also contracted to build a massive constellation of spy satellites for the DOD and is considered a leading candidate for launching space-based interceptors envisioned as part of Trump’s “Golden Dome” missile-defense plan.Among the avalanche of reactions to the incendiary spectacle unfolding in real time, one of the most extreme was from Trump’s influential former adviser Steve Bannon, who called on the president to seize and nationalize SpaceX. And in an interview with the New York Times, Bannon, without evidence, accused Musk, a naturalized U.S. citizen, of being an “illegal alien” who “should be deported from the country immediately.”NASA, for its part, attempted to stay above the fray via a carefully worded late-afternoon statement from the space agency’s press secretary Bethany Stevens: “NASA will continue to execute upon the President’s vision for the future of space,” Stevens wrote. “We will continue to work with our industry partners to ensure the President’s objectives in space are met.”The response from the stock market was, in its own way, much less muted. SpaceX is not a publicly traded company. But Musk’s electric car company Tesla is. And it experienced a massive sell-off at the end of June 5’s trading day: Tesla’s share price fell down by 14 percent, losing the company a whopping $152 billion of its market value.Today a rumored détente phone conversation between the two men has apparently been called off, and Trump has reportedly said he now intends to sell the Tesla he purchased in March in what was then a gesture of support for Musk. But there are some signs the rift may yet heal: Musk has yet to be deported; SpaceX has not been shut down; Tesla’s stock price is surging back from its momentary heavy losses; and it seems NASA astronauts won’t be stranded on Earth or on the ISS for the time being.Even so, the entire sordid episode—and the possibility of further messy clashes between Trump and Musk unfolding in public—highlights a fundamental vulnerability at the heart of the nation’s deep reliance on SpaceX for access to space. Outsourcing huge swaths of civil and military space programs to a disruptively innovative private company effectively controlled by a single individual certainly has its rewards—but no shortage of risks, too.

If President Trump cancels the contracts for Elon Musk’s private spaceflight company, the federal government would struggle to achieve many goals in orbit and beyond.

June 3, 20255 min readAre We Ready for Death in Space?NASA has quietly taken steps to prepare for a death in space. We need to ask how nations will deal with this inevitability now, as more people start traveling off the planetBy Peter Cummings edited by Lee Billings SciePro/Science Photo Library/Getty ImagesIn 2012 NASA stealthily slipped a morgue into orbit.No press release. No fanfare. Just a sealed, soft-sided pouch tucked in a cargo shipment to the International Space Station (ISS) alongside freeze-dried meals and scientific gear. Officially, it was called the Human Remains Containment Unit (HRCU). To the untrained eye it looked like a shipping bag for frozen cargo. But to NASA it marked something far more sobering: a major advance in preparing for death beyond Earth.As a kid, I obsessed over how astronauts went to the bathroom in zero gravity. Now, decades later, as a forensic pathologist and a perennial applicant to NASA’s astronaut corps, I find myself fixated on a darker, more haunting question:On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.What would happen if an astronaut died out there? Would they be brought home, or would they be left behind? If they expired on some other world, would that be their final resting place? If they passed away on a spacecraft or space station, would their remains be cast off into orbit—or sent on an escape-velocity voyage to the interstellar void?NASA, it turns out, has begun working out most of these answers. And none too soon. Because the question itself is no longer if someone will die in space—but when.A Graying CorpsNo astronaut has ever died of natural causes off-world. In 1971 the three-man crew of the Soviet Soyuz 11 mission asphyxiated in space when their spacecraft depressurized shortly before its automated atmospheric reentry—but their deaths were only discovered once the spacecraft landed on Earth. Similarly, every U.S. spaceflight fatality to date has occurred within Earth’s atmosphere—under gravity, oxygen and a clear national jurisdiction. That matters, because it means every spaceflight mortality has played out in familiar territory.But planned missions are getting longer, with destinations beyond low-Earth orbit. And NASA’s astronaut corps is getting older. The average age now hovers around 50—an age bracket where natural death becomes statistically relevant, even for clean-living fitness buffs. Death in space is no longer a thought experiment. It’s a probability curve—and NASA knows it.In response, the agency is making subtle but decisive moves. The most recent astronaut selection cycle was extended—not only to boost intake but also to attract younger crew members capable of handling future long-duration missions.NASA’s Space MorgueIf someone were to die aboard the ISS today, their body would be placed in the HRCU, which would then be sealed and secured in a nonpressurized area to await eventual return to Earth.The HRCU itself is a modified version of a military-grade body bag designed to store human remains in hazardous environments. It integrates with refrigeration systems already aboard the ISS to slow decomposition and includes odor-control filters and moisture-absorbent linings, as well as reversed zippers for respectful access at the head. There are straps to secure the body in a seat for return, and patches for name tags and national flags.Cadaver tests conducted in 2019 at Sam Houston State University have proved the system durable. Some versions held for over 40 days before decomposition breached the barrier. NASA even drop-tested the bag from 19 feet to simulate a hard landing.But it’s never been used in space. And since no one yet knows how a body decomposes in true microgravity (or, for that matter, on the moon), no one can really say whether the HRCU would preserve tissue well enough for a forensic autopsy.This is a troubling knowledge gap, because in space, a death isn’t just a tragic loss—it’s also a vital data point. Was an astronaut’s demise from a fluke of their physiology, or an unavoidable stroke of cosmic bad luck—or was it instead a consequence of flaws in a space habitat’s myriad systems that might be found and fixed? Future lives may depend on understanding what went wrong, via a proper postmortem investigation.But there’s no medical examiner in orbit. So NASA trains its crews in something called the In-Mission Forensic Sample Collection protocol. The space agency’s astronauts may avoid talking about it, but they all have it memorized: Document everything, ideally with real-time guidance from NASA flight surgeons. Photograph the body. Collect blood and vitreous fluid, as well as hair and tissue samples. Only then can the remains be stowed in the HRCU.NASA has also prepared for death outside the station—on spacewalks, the moon or deep space missions. If a crew member perishes in vacuum but their remains are retrieved, the body is wrapped in a specially designed space shroud.The goal isn’t just a technical matter of preventing contamination. It’s psychological, too, as a way of preserving dignity. Of all the “firsts” any space agency hopes to achieve, the first-ever human corpse drifting into frame on a satellite feed is not among them.If a burial must occur—in lunar regolith or by jettisoning into solar orbit—the body will be dutifully tracked and cataloged, treated forevermore as a hallowed artifact of space history.Such gestures are also of relevance to NASA’s plans for off-world mourning; grief and memorial protocols are now part of official crew training. If a death occurs, surviving astronauts are tasked with holding a simple ceremony to honor the fallen—then to move on with their mission.Uncharted RealmsSo far we’ve only covered the “easy” questions. NASA and others are still grappling with harder ones.Consider the issue of authority over a death and mortal remains. On the ISS, it’s simple: the deceased astronaut’s home country retains jurisdiction. But that clarity fades as destinations grow more distant and the voyages more diverse: What really happens on space-agency missions to the moon, or to Mars? How might rules change for commercial or multinational spaceflights—or, for that matter, the private space stations and interplanetary settlements that are envisioned by Elon Musk, Jeff Bezos and other tech multibillionaires?NASA and its partners have started drafting frameworks, like the Artemis Accords—agreements signed by more than 50 nations to govern behavior in space. But even those don’t address many intimate details of death.What happens, for instance, if foul play is suspected?The Outer Space Treaty, a legal document drafted in 1967 under the United Nations that is humanity’s foundational set of rules for orbit and beyond, doesn’t say.Of course, not everything can be planned for in advance. And NASA has done an extraordinary job of keeping astronauts in orbit alive. But as more people venture into space, and as the frontier stretches to longer voyages and farther destinations, it becomes a statistical certainty that sooner or later someone won’t come home.When that happens, it won’t just be a tragedy. It will be a test. A test of our systems, our ethics and our ability to adapt to a new dimension of mortality. To some, NASA’s preparations for astronautical death may seem merely morbid, even silly—but that couldn’t be further from the truth.Space won’t care of course, whenever it claims more lives. But we will. And rising to that grim occasion with reverence, rigor and grace will define not just policy out in the great beyond—but what it means to be human there, too.

June 3, 20258 min readWhite House Budget Plan Would Devastate U.S. Space ScienceScientists are rallying to reverse ruinous proposed cuts to both NASA and the National Science FoundationBy Nadia Drake edited by Lee BillingsFog shrouds the iconic Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida in this photograph from February 25, 2025. Gregg Newton/AFP via GettyLate last week the Trump Administration released its detailed budget request for fiscal year 2026 —a request that, if enacted, would be the equivalent of carpet-bombing the national scientific enterprise.“This is a profound, generational threat to scientific leadership in the United States,” says Casey Dreier, chief of space policy at the Planetary Society, a science advocacy group. “If implemented, it would fundamentally undermine and potentially devastate the most unique capabilities that the U.S. has built up over a half-century.”The Trump administration’s proposal, which still needs to be approved by Congress, is sure to ignite fierce resistance from scientists and senators alike. Among other agencies, the budget deals staggering blows to NASA and the National Science Foundation (NSF), which together fund the majority of U.S. research in astronomy, astrophysics, planetary science, heliophysics and Earth science —all space-related sciences that have typically mustered hearty bipartisan support.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.The NSF supports ground-based astronomy, including such facilities as the Nobel Prize–winning gravitational-wave detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO), globe-spanning arrays of radio telescopes, and cutting-edge observatories that stretch from Hawaii to the South Pole. The agency faces a lethal 57 percent reduction to its $9-billion budget, with deep cuts to every program except those in President Trump’s priority areas, which include artificial intelligence and quantum information science. NASA, which funds space-based observatories, faces a 25 percent reduction, dropping the agency’s $24.9-billion budget to $18.8 billion. The proposal beefs up efforts to send humans to the moon and to Mars, but the agency’s Science Mission Directorate —home to Mars rovers, the Voyager interstellar probes, the James Webb Space Telescope (JWST), the Hubble Space Telescope, and much more —is looking at a nearly 50 percent reduction, with dozens of missions canceled, turned off or operating on a starvation diet.“It’s an end-game scenario for science at NASA,” says Joel Parriott, director of external affairs and public policy at the American Astronomical Society. “It’s not just the facilities. You’re punching a generation-size hole, maybe a multigenerational hole, in the scientific and technical workforce. You don’t just Cryovac these people and pull them out when the money comes back. People are going to move on.”Adding to the chaos, on Saturday President Trump announced that billionaire entrepreneur and private astronaut Jared Isaacman was no longer his pick for NASA administrator—just days before the Senate was set to confirm Isaacman’s nomination. Initial reports—which have now been disputed—explained the president’s decision as stemming from his discovery that Isaacman recently donated money to Democratic candidates. Regardless of the true reason, the decision leaves both NASA and the NSF, whose director abruptly resigned in April, with respective placeholder “acting” leaders at the top. That leadership vacuum significantly weakens the agencies’ ability to fight the proposed budget cuts and advocate for themselves. “What’s more inefficient than a rudderless agency without an empowered leadership?” Dreier asks.Actions versus WordsDuring his second administration, President Trump has repeatedly celebrated U.S. leadership in space. When he nominated Isaacman last December, Trump noted “NASA’s mission of discovery and inspiration” and looked to a future of “groundbreaking achievements in space science, technology and exploration.” More recently, while celebrating Hubble’s 35th anniversary in April, Trump called the telescope “a symbol of America’s unmatched exploratory might” and declared that NASA would “continue to lead the way in fueling the pursuit of space discovery and exploration.” The administration’s budgetary actions speak louder than Trump’s words, however. Instead of ushering in a new golden age of space exploration—or even setting up the U.S. to stay atop the podium—the president’s budget “narrows down what the cosmos is to moon and Mars and pretty much nothing else,” Dreier says. “And the cosmos is a lot bigger, and there’s a lot more to learn out there.”Dreier notes that when corrected for inflation, the overall NASA budget would be the lowest it’s been since 1961. But in April of that year, the Soviet Union launched the first human into orbit, igniting a space race that swelled NASA’s budget and led to the Apollo program putting American astronauts on the moon. Today China’s rapidprogress and enormous ambitions in space would make the moment ripe for a 21st-century version of this competition, with the U.S. generously funding its own efforts to maintain pole position. Instead the White House’s budget would do the exact opposite.“The seesaw is sort of unbalanced,” says Tony Beasley, director of the NSF-funded National Radio Astronomy Observatory (NRAO). “On the one side, we’re saying, ‘Well, China’s kicking our ass, and we need to do something about that.’ But then we’re not going to give any money to anything that might actually do that.”How NASA will achieve a crewed return to the moon and send astronauts to Mars—goals that the agency now considers part of “winning the second space race”—while also maintaining its leadership in science is unclear.“This is Russ Vought’s budget,” Dreier says, referring to the director of the White House’s Office of Management and Budget (OMB), an unelected bureaucrat who has been notorious for his efforts to reshape the U.S. government by weaponizing federal funding. “This isn’t even Trump’s budget. Trump’s budget would be good for space. This one undermines the president’s own claims and ambitions when it comes to space.”“Low Expectations” at the High FrontierRumors began swirling about the demise of NASA science in April, when a leaked OMB document described some of the proposed cuts and cancellations. Those included both the beleaguered, bloated Mars Sample Return (MSR) program and the on-time, on-budget Nancy Grace Roman Space Telescope, the next astrophysics flagship mission.The top-line numbers in the more fleshed-out proposal are consistent with that document, and MSR would still be canceled. But Roman would be granted a stay of execution: rather than being zeroed out, it would be put on life support.“It’s a reprieve from outright termination, but it’s still a cut for functionally no reason,” Dreier says. “In some ways, [the budget] is slightly better than I was expecting. But I had very low expectations.”In the proposal, many of the deepest cuts would be made to NASA science, which would sink from $7.3 billion to $3.9 billion. Earth science missions focused on carbon monitoring and climate change, as well as programs aimed at education and workforce diversity, would be effectively erased by the cuts. But a slew of high-profile planetary science projects would suffer, too, with cancellations proposed for two future Venus missions, the Juno mission that is currently surveilling Jupiter, the New Horizons mission that flew by Pluto and two Mars orbiters. (The Dragonfly mission to Saturn’s moon Titan would survive, as would the flagship Europa Clipper spacecraft, which launched last October.) NASA’s international partnerships in planetary science fare poorly, too, as the budget rescinds the agency’s involvement with multiple European-led projects, including a Venus mission and Mars rover.The proposal is even worse for NASA astrophysics—the study of our cosmic home—which “really takes it to the chin,” Dreier says, with a roughly $1-billion drop to just $523 million. In the president’s proposal, only three big astrophysics missions would survive: the soon-to-launch Roman and the already-operational Hubble and JWST. The rest of NASA’s active astrophysics missions, which include the Chandra X-ray Observatory, the Fermi Gamma-Ray Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), would be severely pared back or zeroed out. Additionally, the budget would nix NASA’s contributions to large European missions, such as a future space-based gravitational-wave observatory.“This is the most powerful fleet of missions in the history of the study of astrophysics from space,” says John O’Meara, chief scientist at the W. M. Keck Observatory in Hawaii and co-chair of a recent senior review panel that evaluated NASA’s astrophysics missions. The report found that each reviewed mission “continues to be capable of producing important, impactful science.” This fleet, O’Meara adds, is more than the sum of its parts, with much of its power emerging from synergies among multiple telescopes that study the cosmos in many different types, or wavelengths, of light.By hollowing out NASA’s science to ruthlessly focus on crewed missions, the White House budget might be charitably viewed as seeking to rekindle a heroic age of spaceflight—with China’s burgeoning space program as the new archrival. But even for these supposedly high-priority initiatives, the proposed funding levels appear too anemic and meager to give the U.S. any competitive edge. For example, the budget directs about $1 billion to new technology investments to support crewed Mars missions while conservative estimates have projected that such voyages would cost hundreds of billions of dollars more.“It cedes U.S. leadership in space science at a time when other nations, particularly China, are increasing their ambitions,” Dreier says. “It completely flies in the face of the president’s own stated goals for American leadership in space.”Undermining the FoundationThe NSF’s situation, which one senior space scientist predicted would be “diabolical” when the NASA numbers leaked back in April, is also unsurprisingly dire. Unlike NASA, which is focused on space science and exploration, the NSF’s programs span the sweep of scientific disciplines, meaning that even small, isolated cuts—let alone the enormous ones that the budget has proposed—can have shockingly large effects on certain research domains.“Across the different parts of the NSF, the programs that are upvoted are the president’s strategic initiatives, but then everything else gets hit,” Beasley says.Several large-scale NSF-funded projects would escape more or less intact. Among these are the panoramic Vera C. Rubin Observatory, scheduled to unveil its first science images later this month, and the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope. The budget also moves the Giant Magellan Telescope, which would boast starlight-gathering mirrors totaling more than 25 meters across, into a final design phase. All three of those facilities take advantage of Chile’s pristine dark skies. Other large NSF-funded projects that would survive include the proposed Next Generation Very Large Array of radio telescopes in New Mexico and several facilities at the South Pole, such as the IceCube Neutrino Observatory.If this budget is enacted, however, NSF officials anticipate only funding a measly 7 percent of research proposals overall rather than 25 percent; the number of graduate research fellowships awarded would be cleaved in half, and postdoctoral fellowships in the physical sciences would drop to zero. NRAO’s Green Bank Observatory — home to the largest steerable single-dish radio telescope on the planet — would likely shut down. So would other, smaller observatories in Arizona and Chile. The Thirty Meter Telescope, a humongous, perennially embattled project with no clear site selection, would be canceled. And the budget proposes closing one of the two gravitational-wave detectors used by the LIGO collaboration—whose observations of colliding black holes earned the 2017 Nobel Prize in Physics—even though both detectors need to be online for LIGO’s experiment to work. Even factoring in other operational detectors, such as Virgo in Europe and the Kamioka Gravitational Wave Detector (KAGRA) in Japan, shutting down half of LIGO would leave a gaping blind spot in humanity’s gravitational-wave view of the heavens.“The consequences of this budget are that key scientific priorities, on the ground and in space, will take at least a decade longer—or not be realized at all,” O’Meara says. “The universe is telling its story at all wavelengths. It doesn’t care what you build, but if you want to hear that story, you must build many things.”Dreier, Parriott and others are anticipating fierce battles on Capitol Hill. And already both Democratic and Republican legislators have issued statement signaling that they won’t support the budget request as is. “This sick joke of a budget is a nonstarter,” said Representative Zoe Lofgren of California, ranking member of the House Committee on Science, Space, and Technology, in a recent statement. And in an earlier statement, Senator Susan Collins of Maine, chair of the powerful Senate Committee on Appropriations, cautioned that “the President’s Budget Request is simply one step in the annual budget process.”The Trump administration has “thrown a huge punch here, and there will be a certain back-reaction, and we’ll end up in the middle somewhere,” Beasley says. “The mistake you can make right now is to assume that this represents finalized decisions and the future—because it doesn’t.”

Physicists who record rocket launches and landings, most often by SpaceX, are learning important facts about the acoustics of spaceflight.

Let's talk about spaceplanes. Since the Space Shuttle, spaceplanes have, at best, been a niche part of the space transportation business. The US Air Force's uncrewed X-37B and a similar vehicle operated by China's military are the only spaceplanes to reach orbit since the last shuttle flight in 2011, and both require a lift from a conventional rocket. Virgin Galactic's suborbital space tourism platform is also a spaceplane of sorts. A generation or two ago, one of the chief arguments in favor of spaceplanes was that they were easier to recover and reuse. Today, SpaceX routinely reuses capsules and rockets that look much more like conventional space vehicles than the winged designs of yesteryear. Spaceplanes are undeniably alluring in appearance, but they have the drawback of carrying extra weight (wings) into space that won't be used until the final minutes of a mission.

One of China's commercial rockets returns to flight. The Kinetica-1 rocket launched Wednesday for the first time since a failure doomed its previous attempt to reach orbit in December, according to the vehicle's developer and operator, CAS Space. The Kinetica-1 is one of several small Chinese solid-fueled launch vehicles managed by a commercial company, although with strict government oversight and support. CAS Space, a spinoff of the Chinese Academy of Sciences, said its Kinetica-1 rocket deployed multiple payloads with "excellent orbit insertion accuracy." This was the seventh flight of a Kinetica-1 rocket since its debut in 2022. Back in action ... "Kinetica-1 is back!" CAS Space posted on X. "Mission Y7 has just successfully sent six satellites into designated orbits, making a total of 63 satellites or 6 tons of payloads since its debut. Lots of missions are planned for the coming months. 2025 is going to be awesome." The Kinetica-1 is designed to place up to 2 metric tons of payload into low-Earth orbit. A larger liquid-fueled rocket, Kinetica-2, is scheduled to debut later this year.

French spaceplane startup AndroMach announced May 15 that it received a contract from CNES, the French space agency, to begin testing an early prototype of its Banger v1 rocket engine, European Spaceflight reports. Founded in 2023, AndroMach is developing a pair of spaceplanes that will be used to perform suborbital and orbital missions to space. A suborbital spaceplane will utilize turbojet engines for horizontal takeoff and landing, and a pressure-fed biopropane/liquid oxygen rocket engine to reach space. Test flights of this smaller vehicle will begin in early 2027. A risky proposition ... A larger ÉTOILE "orbital shuttle" is designed to be launched by various small launch vehicles and will be capable of carrying payloads of up to 100 kilograms (220 pounds). According to the company, initial test flights of ÉTOILE are expected to begin at the beginning of the next decade. It's unclear how much CNES is committing to AndroMach through this contract, but the company says the funding will support testing of an early demonstrator for its propane-fueled engine, with a focus on evaluating its thermodynamic performance. It's good to see European governments supporting developments in commercial space, but the path to a small commercial orbital spaceplane is rife with risk. (submitted by EllPeaTea) Dawn Aerospace is taking orders. Another spaceplane company in a more advanced stage of development says it is now taking customer orders for flights to the edge of space. New Zealand-based Dawn Aerospace said it is beginning to take orders for its remotely piloted, rocket-powered suborbital spaceplane, known as Aurora, with first deliveries expected in 2027, Aviation Week & Space Technology reports. "This marks a historic milestone: the first time a space-capable vehicle—designed to fly beyond the Kármán line (100 kilometers or 328,000 feet)—has been offered for direct sale to customers," Dawn Aerospace said in a statement. While it hasn't yet reached space, Dawn's Aurora spaceplane flew to supersonic speed for the first time last year and climbed to an altitude of 82,500 feet (25.1 kilometers), setting a record for the fastest climb from a runway to 20 kilometers. Further along ... Aurora is small in stature, measuring just 15.7 feet (4.8 meters) long. It's designed to loft a payload of up to 22 pounds (10 kilograms) above the Kármán line for up to three minutes of microgravity, before returning to a runway landing. Eventually, Dawn wants to reduce the turnaround time between Aurora flights to less than four hours. "Aurora is set to become the fastest and highest-flying aircraft ever to take off from a conventional runway, blending the extreme performance of rocket propulsion with the reusability and operational simplicity of traditional aviation," Dawn said. The company's business model is akin to commercial airlines, where operators can purchase an aircraft directly from a manufacturer and manage their own operations. (submitted by EllPeaTea) India's workhorse rocket falls short of orbit. In a rare setback, Indian Space Research Organisation's (ISRO) launch vehicle PSLV-C61 malfunctioned and failed to place a surveillance satellite into the intended orbit last weekend, the Times of India reported. The Polar Satellite Launch Vehicle lifted off from a launch pad on the southeastern coast of India early Sunday, local time, with a radar reconnaissance satellite named EOS-09, or RISAT-1B. The satellite was likely intended to gather intelligence for the Indian military. "The country's military space capabilities, already hindered by developmental challenges, have suffered another setback with the loss of a potential strategic asset," the Times of India wrote. What happened? ... V. Narayanan, ISRO's chairman, later said that the rocket’s performance was normal until the third stage. The PSLV's third stage, powered by a solid rocket motor, suffered a "fall in chamber pressure" and the mission could not be accomplished, Narayanan said. Investigators are probing the root cause of the failure. Telemetry data indicated the rocket deviated from its planned flight path around six minutes after launch, when it was traveling more than 12,600 mph (5.66 kilometers per second), well short of the speed it needed to reach orbital velocity. The rocket and its payload fell into the Indian Ocean south of the launch site. This was the first PSLV launch failure in eight years, ending a streak of 21 consecutive successful flights. (submitted by EllPeaTea) SES makes a booking with Impulse Space. SES, owner of the world's largest fleet of geostationary satellites, plans to use Impulse Space’s Helios kick stage to take advantage of lower-cost, low-Earth-orbit (LEO) launch vehicles and get its satellites quickly into higher orbits, Aviation Week & Space Technology reports. SES hopes the combination will break a traditional launch conundrum for operators of medium-Earth-orbit (MEO) and geostationary orbit (GEO). These operators often must make a trade-off between a lower-cost launch that puts them farther from their satellite's final orbit, or a more expensive launch that can expedite their satellite's entry into service. A matter of hours ... On Thursday, SES and Impulse Space announced a multi-launch agreement to use the methane-fueled Helios kick stage. "The first mission, currently planned for 2027, will feature a dedicated deployment from a medium-lift launcher in LEO, followed by Helios transferring the 4-ton-class payload directly to GEO within eight hours of launch," Impulse said in a statement. Typically, this transit to GEO takes several weeks to several months, depending on the satellite's propulsion system. "Today, we’re not only partnering with Impulse to bring our satellites faster to orbit, but this will also allow us to extend their lifetime and accelerate service delivery to our customers," said Adel Al-Saleh, CEO of SES. "We're proud to become Helios' first dedicated commercial mission." Unpacking China's spaceflight patches. There's a fascinating set of new patches Chinese officials released for a series of launches with top-secret satellites over the last two months, Ars reports. These four patches depict Buddhist gods with a sense of artistry and sharp colors that stand apart from China's previous spaceflight emblems, and perhaps—or perhaps not—they can tell us something about the nature of the missions they represent. The missions launched so-called TJS satellites toward geostationary orbit, where they most likely will perform missions in surveillance, signals intelligence, or missile warning.  Making connections ... It's not difficult to start making connections between the Four Heavenly Gods and the missions that China's TJS satellites likely carry out in space. A protector with an umbrella? An all-seeing entity? This sounds like a possible link to spy craft or missile warning, but there's a chance Chinese officials approved the patches to misdirect outside observers, or there's no connection at all. China aims for an asteroid. China is set to launch its second Tianwen deep space exploration mission late May, targeting both a near-Earth asteroid and a main belt comet, Space News reports. The robotic Tianwen-2 spacecraft is being integrated with a Long March 3B rocket at the Xichang Satellite Launch Center in southwest China, the country's top state-owned aerospace contractor said. Airspace closure notices indicate a four-hour-long launch window opening at noon EDT (16:00–20:00 UTC) on May 28. Backup launch windows are scheduled for May 29 and 30. New frontiers ... Tianwen-2's first goal is to collect samples from a near-Earth asteroid designated 469219 Kamoʻoalewa, or 2016 HO3, and return them to Earth in late 2027 with a reentry module. The Tianwen-2 mothership will then set a course toward a comet for a secondary mission. This will be China's first sample return mission from beyond the Moon. The asteroid selected as the target for Tianwen-2 is believed by scientists to be less than 100 meters, or 330 feet, in diameter, and may be made of material thrown off the Moon some time in its ancient past. Results from Tianwen-2 may confirm that hypothesis. (submitted by EllPeaTea) Upgraded methalox rocket flies from Jiuquan. Another one of China's privately funded launch companies achieved a milestone this week. Landspace launched an upgraded version of its Zhuque-2E rocket Saturday from the Jiuquan launch base in northwestern China, Space News reports. The rocket delivered six satellites to orbit for a range of remote sensing, Earth observation, and technology demonstration missions. The Zhuque-2E is an improved version of the Zhuque-2, which became the first liquid methane-fueled rocket in the world to reach orbit in 2023. Larger envelope ... This was the second flight of the Zhuque-2E rocket design, but the first to utilize a wider payload fairing to provide more volume for satellites on their ride into space. The Zhuque-2E is a stepping stone toward a much larger rocket Landspace is developing called the Zhuque-3, a stainless steel launcher with a reusable first stage booster that, at least outwardly, bears some similarities to SpaceX's Falcon 9. (submitted by EllPeaTea) FAA clears SpaceX for Starship Flight 9. The Federal Aviation Administration gave the green light Thursday for SpaceX to launch the next test flight of its Starship mega-rocket as soon as next week, following two consecutive failures earlier this year, Ars reports. The failures set back SpaceX's Starship program by several months. The company aims to get the rocket's development back on track with the upcoming launch, Starship's ninth full-scale test flight since its debut in April 2023. Starship is central to SpaceX's long-held ambition to send humans to Mars and is the vehicle NASA has selected to land astronauts on the Moon under the umbrella of the government's Artemis program. Targeting Tuesday, for now ... In a statement Thursday, the FAA said SpaceX is authorized to launch the next Starship test flight, known as Flight 9, after finding the company "meets all of the rigorous safety, environmental and other licensing requirements." SpaceX has not confirmed a target launch date for the next launch of Starship, but warning notices for pilots and mariners to steer clear of hazard areas in the Gulf of Mexico suggest the flight might happen as soon as the evening of Tuesday, May 27. The rocket will lift off from Starbase, Texas, SpaceX's privately owned spaceport near the US-Mexico border. The FAA's approval comes with some stipulations, including that the launch must occur during "non-peak" times for air traffic and a larger closure of airspace downrange from Starbase. Space Force is fed up with Vulcan delays. In recent written testimony to a US House of Representatives subcommittee that oversees the military, the senior official responsible for purchasing launches for national security missions blistered one of the country's two primary rocket providers, Ars reports. The remarks from Major General Stephen G. Purdy, acting assistant secretary of the Air Force for Space Acquisition and Integration, concerned United Launch Alliance and its long-delayed development of the large Vulcan rocket. "The ULA Vulcan program has performed unsatisfactorily this past year," Purdy said in written testimony during a May 14 hearing before the House Armed Services Committee's Subcommittee on Strategic Forces. This portion of his testimony did not come up during the hearing, and it has not been reported publicly to date. Repairing trust ... "Major issues with the Vulcan have overshadowed its successful certification resulting in delays to the launch of four national security missions," Purdy wrote. "Despite the retirement of highly successful Atlas and Delta launch vehicles, the transition to Vulcan has been slow and continues to impact the completion of Space Force mission objectives." It has widely been known in the space community that military officials, who supported Vulcan with development contracts for the rocket and its engines that exceeded $1 billion, have been unhappy with the pace of the rocket's development. It was originally due to launch in 2020. At the end of his written testimony, Purdy emphasized that he expected ULA to do better. As part of his job as the Service Acquisition Executive for Space (SAE), Purdy noted that he has been tasked to transform space acquisition and to become more innovative. "For these programs, the prime contractors must re-establish baselines, establish a culture of accountability, and repair trust deficit to prove to the SAE that they are adopting the acquisition principles necessary to deliver capabilities at speed, on cost and on schedule." SpaceX's growth on the West Coast. SpaceX is moving ahead with expansion plans at Vandenberg Space Force Base, California, that will double its West Coast launch cadence and enable Falcon Heavy rockets to fly from California, Spaceflight Now reports. Last week, the Department of the Air Force issued its Draft Environmental Impact Statement (EIS), which considers proposed modifications from SpaceX to Space Launch Complex 6 (SLC-6) at Vandenberg. These modifications will include changes to support launches of Falcon 9 and Falcon Heavy rockets, the construction of two new landing pads for Falcon boosters adjacent to SLC-6, the demolition of unneeded structures at SLC-6, and increasing SpaceX’s permitted launch cadence from Vandenberg from 50 launches to 100. Doubling the fun ... The transformation of SLC-6 would include quite a bit of overhaul. Its most recent tenant, United Launch Alliance, previously used it for Delta IV rockets from 2006 through its final launch in September 2022. The following year, the Space Force handed over the launch pad to SpaceX, which lacked a pad at Vandenberg capable of supporting Falcon Heavy missions. The estimated launch cadence between SpaceX’s existing Falcon 9 pad at Vandenberg, known as SLC-4E, and SLC-6 would be a 70-11 split for Falcon 9 rockets in 2026, with one Falcon Heavy at SLC-6, for a total of 82 launches. That would increase to a 70-25 Falcon 9 split in 2027 and 2028, with an estimated five Falcon Heavy launches in each of those years.

Researchers at the German Aerospace Center (DLR) have developed MiniFix, a fully 3D printed syringe-based biological fixation system engineered for spaceflight. Successfully deployed in five MAPHEUS sounding rocket missions, MiniFix represents a breakthrough in experimental payload design, combining rapid prototyping, modularity, and robust performance in microgravity environments, combining rapid prototyping with modular, lightweight, and reliable performance under the extreme conditions of microgravity research. A 3D printing milestone for space life science Unlike conventional biological fixation systems, MiniFix is entirely produced via Fused Deposition Modeling (FDM). Key components, including the syringe holders, baseplate, and housing, were fabricated using desktop 3D printers, notably a Prusa MK3+, with 0.4 mm nozzles and a 0.3 mm layer height. This approach enabled fast, low-cost iteration and customization of parts to suit different missions and experimental needs. The system has undergone structural revisions using three different filaments; PLA (Polylactic Acid), used in initial missions (MAPHEUS-09 and -12), PETG (Polyethylene Terephthalate Glycol), chosen for enhanced mechanical durability (MAPHEUS-14), and GreenTEC Pro, a compostable bioplastic with high thermal resistance, used in MAPHEUS-15. This made MiniFix the first biologically compostable experiment structure to fly aboard a rocket. Sectional, translucent view through the MiniFix fixation system. Image via Sebastian Feles / DLR. Modular design for rapid adaptation MiniFix features a dual-syringe configuration, where a fixative and a biological sample are housed in vertically stacked syringes. Syringe actuation is handled by NEMA11 stepper motors coupled with linear actuators, allowing precise fluid dispensing. The hardware is modular and sterilizable, enabling pre-assembled syringe units to be installed under sterile conditions. Its all-3D printed chassis ensures that custom features, like integrated lighting for plant experiments, can be introduced quickly without redesigning the core system. This makes MiniFix suitable for various biological models, from unicellular organisms to organoids. Variants of the SBBFS Configuration. Image via Sebastian Feles / DLR. Built-in thermal regulation via waste heat A standout innovation is MiniFix’s passive thermal management system, which uses the heat generated by its stepper motors to maintain stable internal temperatures. With no need for separate heating elements, this system simplifies design, reduces power draw, and lowers overall payload mass, critical factors for sounding rocket missions with strict weight and energy budgets. Test data from MAPHEUS-15 showed that MiniFix maintained an internal temperature of 21.98 °C ±0.12 °C, consuming just 4.6 Wh during operation, even under ambient conditions as low as 4 °C. Space-tested reliability The reliability of this 3D printed structure was put to the test across multiple missions. MiniFix successfully endured extreme conditions, including launch vibrations exceeding 20 g and temperature swings from hypergravity to microgravity and re-entry. Across four missions, its components have shown no degradation or material failure, with post-flight inspections confirming the integrity of all printed parts and mechanical systems. Future applications Beyond fixation, MiniFix could evolve into a general-purpose liquid handling system for space. Its syringe mechanism is already capable of performing programmable mixing and the platform could be adapted for reagent delivery, drug testing, or even microfluidics in space-based manufacturing. Additionally, it exemplifies how additive manufacturing can accelerate experimental development cycles while maintaining reliability in harsh environments. Its open-source microcontroller and modular design ethos further position it as a template for future experimental hardware in life sciences and beyond.3D printing gains traction in space hardware development Additive manufacturing is rapidly transforming the development of spaceflight hardware, from on‑orbit part fabrication to ground-based launch systems. Just this year, ESA’s Metal3D printer aboard the ISS produced the first metal 3D‑printed part in microgravity, now safely back on Earth for analysis. Meanwhile, Nikon and JAXA are collaborating to refine large-scale metal 3D printing for space components, advancing materials and process control to shorten lead times and reduce launch costs. Within this context, DLR’s MiniFix system exemplifies a new wave of highly adaptable, mission‑specific payloads, completely fabricated using desktop FDM printers and bioplastics, optimized for the rigors of sounding rocket flight and microgravity research.
