On the morning of May 5, 1961, Alan Shepard lay strapped on his back inside a capsule the size of a phone booth, breathing pure oxygen through a sealed pressure suit, waiting for a Redstone rocket beneath him to stop misbehaving. The countdown had already slipped past three hours. His bladder was full. The hatch was bolted shut. Mission control kept telling him to hold. Eventually, according to National Geographic’s reconstruction of the morning, Shepard told the engineers he was going to urinate inside the suit, and they let him.

The voltage sensors strapped to his chest and legs went briefly haywire. The cotton long johns beneath the silver pressure layer soaked through. The oxygen flow dried him out before liftoff. Fifteen minutes later he was the first American in space.

The episode is funny in the retelling and it almost always gets told as comedy. The serious part is what it exposed: nobody at NASA in the spring of 1961 had thought seriously about what a human body does over a four-hour hold inside a sealed suit wired to live electronics.

A 15-minute flight, a four-hour wait

Freedom 7’s mission was meant to be brief. Suborbital. Up and down. The capsule reached an altitude of 116.5 miles before splashing into the Atlantic, as Astronomy magazine’s day-in-history account records. Total flight time: about fifteen minutes.

The launch prep was a different story. Shepard had been awake since the early hours of the morning. He ate breakfast, suited up, and was sealed inside Freedom 7 in the pre-dawn dark, with the hatch bolted shut roughly two hours before the scheduled 7:20 a.m. launch. That window opened and closed without a liftoff.

Weather rolled in. A small inverter on the booster started acting up. An IBM 7090 computer at Goddard wanted to be checked. Each issue cost twenty minutes, then forty, then an hour. By the time the candle was finally lit at 9:34 a.m., Shepard had been horizontal in the capsule for more than four hours.

The plan was that he wouldn’t need to

There was no urine collection device inside the Mercury suit because the mission, as designed, did not require one. Fifteen minutes is shorter than most car commutes. The Mercury planners assumed the astronaut would empty his bladder before suit-up and be fine until splashdown.

What they did not plan for was the hold.

Shepard asked over the comm loop if he could get out and use the bathroom. The answer came back from the capsule communicator: no. Unstrapping him, opening the hatch, walking him down the gantry, suiting him back up, and resealing Freedom 7 would have cost hours and risked the whole mission. The Soviets had already put Yuri Gagarin in orbit on April 12, just three and a half weeks earlier. Every hour the U.S. delayed was another hour the rest of the world spent watching the Soviet Union look like the future.

Shepard pressed the question. According to the Smithsonian National Air and Space Museum’s account of the flight, no provision had been made for him to relieve himself, and the launch team eventually told him to go in the suit. The flight surgeons worried about the medical telemetry shorting out. The electrical engineers worried about the wires.

What the sensors actually did

The Mercury biomedical harness was not subtle. Shepard had electrodes on his chest reading heart rate, a respirometer at his face mask, and thermistors reading skin temperature at several locations including his lower torso and thighs. The wiring ran through the suit and into a connector at his waist that fed the capsule’s telemetry system.

When the urine pooled, the readings spiked. Heart-rate channels jumped. Skin-temperature numbers swung. The biomedical team at the Cape watched the trace and, briefly, lost confidence in what they were looking at.

The pure oxygen environment inside the suit then did what it does in a closed, ventilated space. It evaporated the moisture. By the time the engines lit, Shepard was uncomfortable but dry, and the sensors had settled back into something readable.

Forty-five million Americans watched the launch on live television, as the WDBJ7 anniversary recap notes. None of them knew. Shepard’s now-famous instruction to the launch team was broadcast in the clear. The other parts of that conversation were not.

The plumbing question, redesigned slowly

The popular telling of this story claims NASA redesigned every subsequent flight’s plumbing from scratch the next week. That overstates what actually happened. The fixes came in stages, and they were never as elegant as the rocket they were attached to.

Gus Grissom’s Liberty Bell 7 flight in July 1961 was the next Mercury launch and it, too, was suborbital and short. Grissom flew without a true urine collection device. By the time John Glenn was preparing to orbit the Earth in early 1962 — a flight that would last several hours — the problem could no longer be ignored. NASA engineers fitted Glenn’s suit with a modified condom catheter draining into a rubber collection bag strapped to his thigh. The design was crude. It leaked. Glenn used it anyway.

By the Gemini program, the urine collection assembly had become a standard suit component, with a one-way valve and a dump line that vented overboard. By Apollo, astronauts had dedicated devices for both liquid and solid waste, the latter being a now-infamous adhesive bag system that nobody on the lunar missions remembered fondly.

The through-line is that Shepard’s four-hour hold made the engineers stop assuming the human body would behave for the duration of the mission. Every long-duration assumption that followed — fluid management, electrolyte balance, the cooling garments under Apollo suits, the way modern spacewalk suits handle waste — traces back to the moment somebody at the Cape realized a flight surgeon’s planning chart did not survive contact with a real bladder on a real launch pad.

The pilot they nearly didn’t fly

The other thing the Shepard story exposes is how close the United States came to not flying him at all. NASA had originally planned a crewed Mercury launch in March 1961. A test flight with the chimpanzee Ham had revealed booster problems that Wernher von Braun insisted be fixed before a human was strapped on top.

That decision pushed the first crewed Mercury launch from March to May. In the gap, on April 12, Yuri Gagarin orbited the Earth. The Soviets had won the race to put a human in space, and they would have won it by a wider margin if von Braun had been less cautious.

Shepard was furious about the delay. He had been told privately in January that he was the choice for the first flight, beating out John Glenn and Gus Grissom. He spent the next several months training for a flight that kept slipping, watching Gagarin take the prize he had been promised.

When NASA finally announced his selection publicly days before the launch, Shepard was the most rehearsed astronaut in the program. He had run the fifteen-minute profile in the simulator more than a hundred times. He had not rehearsed the four-hour wait.

What carries down through the family

In December 2021, Shepard’s daughter Laura Shepard Churchley flew to the edge of space herself, on a Blue Origin New Shepard mission named for him. The launch experienced weather delays — delays of the same flavor, if not the same scale, as the ones that left her father stranded on the pad in 1961.

Her flight lasted about ten minutes. She wore a flight suit with modern moisture-wicking layers and the kind of plumbing options her father had been denied. She did not need them. The wait on the pad was short.

Why this story survives

There are more important facts about Alan Shepard’s flight. Freedom 7 proved that the Redstone-Mercury stack could put a human into ballistic flight and bring him home alive. It gave President Kennedy the political cover to commit, three weeks later, to a crewed lunar landing before the decade was out. It set the trajectory of American spaceflight for the next eight years and arguably the next sixty.

The plumbing story survives because it is the part of the morning that nobody planned. The trajectory was calculated to the second. The heat shield was tested to specifications. The retro-rockets were timed against tables. The bladder was not on anyone’s checklist.

That is what holds matter for. They are when the assumptions in the planning documents meet the body of the person inside the suit. Every long-duration mission since — Skylab, Mir, the ISS, the planned transit to Mars — is built on the recognition that a human inside a sealed system will, given enough time, do something the system was not designed for.

The archival footage from the launch shows Freedom 7 climbing on a pale exhaust plume against a Florida sky. The capsule looks impossibly small. The crowd on the beach looks impossibly close. The man inside is dry, just barely, and about to spend fifteen minutes earning the rest of the program’s future.

He landed in the Atlantic 302 miles downrange, was hoisted out of Freedom 7 by a helicopter from the carrier USS Lake Champlain, and reportedly asked for a glass of water.

The post In May 1961, Alan Shepard became the first American in space, but only after a four-hour hold on the launch pad left him with a full bladder and no collection device, until he finally told the launch team he would have to go inside his sealed pressure suit, briefly short-circuiting his medical sensors appeared first on Space Daily.

John McFall lost his right leg in a motorcycle accident at 19, won a Paralympic bronze medal in Beijing, became an orthopaedic surgeon, and may now become the first person with a physical disability to live and work in orbit.

The proposed flight is not just a symbolic first. If it happens, McFall’s body and prosthesis will become instruments in a medical experiment that six decades of crewed spaceflight have barely begun to design.

The UK Space Agency has signed a memorandum of understanding with the California company Vast that could send McFall to Haven-1, the company’s planned commercial space station. The UK government says the agreement would have the UK Space Agency support Vast in seeking sponsorship to fund McFall’s flight, with Haven-1 scheduled for launch as early as 2027.

McFall could also fly on a private mission to the International Space Station with Vast. Either way, the science is unusually direct: what happens when a body that has already adapted to limb loss enters an environment where every body must relearn fluid balance, movement, heat transfer and load?

McFall was selected for the European Space Agency’s 2022 astronaut reserve and its Fly! feasibility study, which was created to understand and reduce barriers to spaceflight for astronauts with physical disabilities. ESA’s own profile notes that he was selected in November 2022 and took part in the Fly! study after the amputation of his right leg at age 19.

A physiological experiment with a sample size of one

Almost everything known about the human body in microgravity comes from people who passed astronaut medical selection under able-bodied assumptions. McFall’s possible flight puts pressure on that history.

Kirsty Lindsay, a physiotherapist and physiologist who works in spaceflight research, framed the question in an analysis published in The Conversation: what happens to a body that already moves, balances and bears load differently when gravity is removed?

The honest answer is that no one knows yet. That uncertainty is not a weakness in the story. It is the point of the mission.

Writer Arthur C. Clarke imagined an amputee commanding a space station decades before the first human spaceflight. McFall’s mission would turn that old fiction into measurements taken from a real body in orbit.

The fluid-shift problem

On Earth, gravity helps pull fluids toward the legs. In orbit, that vertical gradient disappears, and body fluids shift toward the chest and head.

That headward movement is one of the suspects in spaceflight-associated neuro-ocular syndrome, or SANS, a cluster of eye and vision changes seen in some astronauts after long-duration missions. NASA-linked summaries of SANS describe optic-disc edema, globe flattening, choroidal folds and hyperopic shifts in long-duration astronauts, while noting that the exact cause is still unresolved.

McFall has less lower-limb tissue for fluid to occupy. His fluid shift, and any knock-on effect on vision, may not match the patterns measured in crewmates with two intact lower limbs.

One person cannot settle the science. But one carefully monitored flight can give researchers a first real datapoint where there is now mostly inference.

A spine already under uneven load

Microgravity changes the spine because the usual axial load of standing and walking disappears. Astronauts can experience back pain in flight, and the relationship between spinal unloading, intervertebral discs and postflight reloading remains a live medical concern.

Research on intervertebral-disc damage and spaceflight has described herniated discs after missions and raised the possibility that astronauts may face increased risk when reloaded by re-entry, landing and gravity. The evidence is not simple, because many astronauts also have histories of high-G aviation exposure, but the risk is serious enough to shape medical monitoring.

Lower-limb amputees often move with asymmetry through the pelvis and trunk. Reviews of amputee gait describe spinal, pelvic and hip movement asymmetries, and clinical work has long connected those adaptations with back-pain concerns.

That makes McFall’s spine medically interesting before launch. The key question is not whether his body is fragile. It is how a body already adapted to uneven loading responds when loading disappears, then returns suddenly during landing.

Heat, sockets and the engineering of the body

Temperature regulation is another open question. In microgravity, buoyancy-driven convection is reduced, so warm air does not rise around the body in the ordinary terrestrial way.

That matters because thermoregulation is partly environmental. Airflow, clothing, body shape and equipment all influence how heat moves away from skin.

Then there is the prosthesis itself. A socket is not a generic attachment. It is an intimate piece of engineering, fitted to a residual limb whose volume can change with activity, fluid balance, heat and time.

Prosthetic-socket research has repeatedly treated fit as a central problem, because pressure, shear and small volume changes at the residual-limb interface can determine whether a limb is usable for hours or painful within minutes. McFall’s socket in orbit will be a biomedical instrument as much as a mobility device.

The UK government says the proposed mission would study human physiology, musculoskeletal adaptation, prosthetics in microgravity, and movement and balance in space. Those findings could feed back into lighter, more adaptable prosthetic designs on Earth.

Certification was an engineering problem, not just a medical one

Much of the work to clear McFall has been mechanical rather than philosophical. Engineers and flight surgeons had to ask whether his prosthesis, seat interface, emergency procedures and body mechanics could work during launch, docking, emergency escape and landing.

ESA selected McFall in 2022 for the astronaut reserve and Fly! study. The UK government says he later became the first person with a physical disability to be medically cleared for a long-duration mission.

That clearance does not mean the proposed Haven-1 flight is guaranteed. It means the old assumption that a lower-limb amputation automatically blocks an astronaut from long-duration orbital work has been tested and did not hold.

Space Daily has previously reported on McFall’s medical clearance and on parallel work testing prosthetic mobility in zero gravity.

What a sample of one can actually prove

A two-week flight by one astronaut will not produce statistically powerful conclusions about amputees in microgravity. It will produce something earlier and more basic: a baseline.

The fluid-shift data, spinal imaging, thermal readings, socket-fit logs and movement recordings would become the first entries in a dataset that does not yet exist.

Future missions could build on that baseline. Groups such as AstroAccess have already run parabolic research flights with disabled crews, and commercial stations may give researchers more chances to test bodies that were historically excluded from astronaut selection.

The Vast agreement was formally announced by the UK government as a partnership in which the UK Space Agency would help Vast seek sponsorship for McFall’s mission. Crew would travel aboard SpaceX’s Crew Dragon capsule on a Falcon 9 rocket.

SpaceNews has reported that the UK is treating the Vast partnership as a way to re-establish a sovereign human-spaceflight presence without building a full national human-spaceflight program. The science and the geopolitics are moving together.

McFall has been careful about the way the mission is described. He has said he wants to do the job well, not be treated as a stunt, and that he is happy to be a pioneer only if the work has value for space exploration and for people on Earth.

Tim Peake, the last British ESA astronaut to live aboard the International Space Station, called the agreement a landmark moment for inclusive human spaceflight. That framing is true, but it understates the harder scientific point.

For more than sixty years, space medicine has studied the orbital body through a narrow physiological template. If McFall flies, the next measurement will not begin with that template. It will begin with a residual limb, a socket, a spine under different history, and a body answering questions spaceflight medicine never had to ask.

A team of astronomers has found strong evidence that a star similar to our sun may have eaten one of its own planets. The star, known as TOI-5882, is located about 1,300 light-years from Earth. Researchers discovered that it contains an unusually high amount of lithium, a chemical element that may reveal a dramatic event […]

SpaceX’s first-generation AI data-center satellite is not a faint box in orbit. The reported AI1 design stretches about 70 meters across when deployed, carries a compute payload rated around 120 kilowatts on average and 150 kilowatts at peak, and uses up to 110 square meters of radiators to dump heat into space.

That geometry is why astronomers are watching the idea with such unease. A spacecraft that wide, reflective, and thermally exposed is not just a data-center proposal. It is a moving optical object, crossing the same dark sky that the Vera C. Rubin Observatory is about to scan with the largest digital camera ever built for astronomy.

The number attached to the plan is even stranger. SpaceX has been reported to have filed for or discussed a constellation that could eventually reach as many as 1 million orbital data-center satellites, a scale far beyond the roughly tens of thousands of satellites that already worry observatories.

The old version of this article used a stronger claim: that the full constellation would make the sky as bright as a half-moon everywhere on Earth. That claim is not used here because it could not be verified to a primary public source. The verified warning is narrower, but still severe: peer-reviewed and preprint modeling shows that very large or very bright satellite constellations can damage astronomical images through streaks, glints, detector saturation, false alerts, and added sky background.

A data center with wings wider than a jumbo jet

According to Tom’s Hardware’s report on SpaceX’s AI1 design, the first-generation craft would span about 70 meters when deployed, slightly wider than the 68.4-meter wingspan of a Boeing 747-8. The same report describes an average compute load of 120 kilowatts, a 150-kilowatt peak, and operation at roughly 600 kilometers altitude.

Those figures matter because optical astronomy is sensitive to surface area, altitude, attitude, and reflectivity. A satellite does not have to look bright to the unaided eye to be damaging to a long astronomical exposure. It only has to throw enough sunlight into a detector built to capture photons from objects billions of times fainter.

The radiator figure is the detail that turns a computing story into a sky story. On Earth, a rack-scale AI system can shed heat into circulating air and water. In orbit, there is no air and no water sink. Heat has to leave through radiators, which means a spacecraft built to compute at high power also has to carry surfaces designed to face cold space.

That does not automatically mean AI1 would be disastrously bright. Brightness depends on coating, orientation, phase angle, orbital altitude, and whether the spacecraft is in deployment, parking, or operational mode. But it does mean the relevant object is not a small Starlink-like box. It is a large deployed spacecraft with solar arrays, radiators, and thermal surfaces that astronomers would need to model before they could know how much sky it changes.

Why magnitude 7 became the line astronomers keep returning to

The most repeated technical threshold in the astronomy debate is magnitude 7. In the astronomical magnitude system, lower numbers mean brighter objects. Venus can appear around magnitude -4, bright stars sit near magnitude 0 or 1, and the unaided human eye under dark skies generally stops around magnitude 6 or a little fainter.

For modern survey telescopes, naked-eye visibility is the wrong test. A satellite can be invisible to a person and still saturate a scientific detector. In a 2025 Rubin Observatory LSST workshop report, participants reaffirmed the recommendation that tracked low-Earth-orbit satellites should be no brighter than 7th AB magnitude for the protection of Rubin-style optical survey work.

That recommendation came after years of Starlink mitigation work. A 2020 Rubin Observatory study on LEO satellite brightness and trail effects found that the original Starlink satellites were around g magnitude 4.5, while the experimental DarkSat reached about g magnitude 6.1. The authors wrote that future darkening might reach g magnitude 7, a level at which nonlinear image artifacts could be corrected far below background noise, though the trails would still remain.

A later study of Starlink Mini brightness distributions found that the sky area containing satellites brighter than magnitudes 6 and 7 is largest during twilight. That matters for surveys looking near the Sun’s direction, including searches for near-Earth asteroids and other objects that are hardest to observe in full darkness.

SpaceX has been credited by some astronomers for engaging on brightness mitigation more seriously than many operators. That history is real. It is also the reason AI1 is being judged against a known standard rather than a vague complaint about satellites looking ugly in long-exposure photographs.

Rubin Observatory is built to find faint things quickly

The Vera C. Rubin Observatory sits on Cerro Pachón in Chile, where its Legacy Survey of Space and Time is designed to scan the southern sky repeatedly for ten years. Its wide field, fast cadence, and enormous LSST Camera are what make it powerful. They are also what make it exposed.

Rubin is meant to catch things that move, flare, fade, or appear only once: supernovas, asteroids, distant Solar System bodies, variable stars, and optical counterparts to gravitational-wave events. A satellite trail is not just a line through a pretty picture. It can mask pixels, create residual noise, trigger false detections, and contaminate the statistical measurements that depend on clean repeated imaging.

In a 2022 Rubin satellite-avoidance study, researchers simulated Starlink and OneWeb constellations totaling about 40,000 satellites. They found that, with reasonably accurate orbit forecasts, sacrificing about 10 percent of LSST observing time could cut the fraction of visits with streaks by about half.

That is a mitigation, not a cure. The same paper noted that the need for avoidance depends on satellite brightness, glints, low-surface-brightness residuals, and the effect on alert purity and systematic errors. Those are exactly the unknowns that a very large orbital data-center constellation would multiply.

A million satellites would not behave like 40,000 satellites scaled up neatly on a spreadsheet. Launch cadence, parking orbits, orbit raising, failed units, replacements, attitude modes, and end-of-life disposal would all matter. The sky problem is not just the final architecture. It is the moving assembly line required to build and maintain it.

BlueWalker 3 showed what one large reflective spacecraft can do

Astronomers already have a warning case for large deployed satellites. AST SpaceMobile’s BlueWalker 3 unfolded a large phased-array antenna in 2022, and observers quickly found that it became one of the brighter artificial objects in the night sky.

In a 2023 photometric study of BlueWalker 3, Anthony Mallama, Richard E. Cole, Scott Tilley, Cees Bassa, and Scott Harrington reported that the satellite was most frequently between magnitudes 2.0 and 3.0, and about magnitude 1.4 when near zenith. That is bright enough to rival prominent stars.

A follow-up BlueWalker 3 Redux paper found that the spacecraft later faded, with the average maximum luminosity near zenith reduced from magnitude 1.0 to 2.2. Even after that improvement, the authors wrote that it remained usually bright enough to interfere with astronomical research.

The lesson is not that AI1 would necessarily match BlueWalker 3. The spacecraft are different. The lesson is that large deployed areas in low Earth orbit can become astronomy problems immediately, and mitigation may depend on details that are hard to judge from a promotional render: the underside coating, the solar-array angle, the radiator attitude, and the exact shape of the reflectance curve.

Space Daily has also covered the broader expansion of satellite constellations and radio astronomy concerns, a parallel problem in which optical glare is only one part of a larger fight over the usable sky.

Glints are a separate problem from streaks

Satellite streaks are the obvious signature. A spacecraft crosses a long exposure and draws a bright line across a frame. Glints are shorter and more deceptive: a flat surface briefly catches sunlight and flashes, sometimes for milliseconds, sometimes in a way that looks less like a moving satellite and more like a sudden astrophysical event.

A 2023 study of satellite glints in ZTF and LSST-style surveys found that artificial satellites and space debris can create false point-source alerts that hinder the search for rapid transients. Using more than three years of Zwicky Transient Facility data, the authors estimated that at least 20 percent of isolated single-frame events were related to artificial satellites, with an all-sky glint rate up to 80,000 per hour.

That is the kind of noise Rubin was not built to ignore casually. A survey that watches the sky for one-off flashes has to decide whether a bright pixel is a satellite reflection, a detector artifact, a supernova, a gamma-ray burst afterglow, a kilonova, or something nobody has classified before.

If an orbital data-center satellite has large radiators, solar arrays, and changing attitude states, its glint behavior matters as much as its average brightness. The most damaging moment may not be the average pass. It may be the rare angle where a thermal or power surface sends sunlight straight into the telescope.

The most defensible warning is not a half-moon, but a crowding limit

The strongest recent modeling does not need the unverified half-moon line. In a 2026 study of large and bright satellite constellations, European Southern Observatory astronomer Olivier Hainaut modeled direct trail losses, diffuse satellite light, and scattered sky brightness from proposed constellations.

The results separate dim satellites from bright ones. Hainaut found that a constellation of about 60,000 satellites kept fainter than the V 550-kilometer magnitude-7 recommendation would add only about one ten-thousandth of the natural dark-sky brightness. But the same study found that constellations with 1 million satellites make trails pervasive, and that extremely bright reflector-style constellations could raise the scattered sky background by 200 to 300 percent.

The study also recommended keeping the total satellite population below roughly 100,000 if field-of-view losses are to remain comparable to ordinary technical downtime. That figure is not a law of physics or an international regulation. It is a modeled guardrail for astronomy, and SpaceX’s discussed million-satellite scale sits an order of magnitude beyond it.

This is the defensible version of the warning: not that AI1 has already been proven to turn every sky into permanent moonlight, but that a million large spacecraft would push astronomy into a regime where the existing mitigation playbook was never designed to operate. At that scale, even individually managed satellites become a foreground population.

For now, the sky still changes the old way. Twilight lowers, satellites brighten and fade, and the dark between them returns. The question raised by orbital data centers is whether that darkness remains a background condition of astronomy, or becomes something telescopes have to chase between machines.

When Butch Wilmore and Suni Williams finally splashed down off the Florida panhandle in late March 2025 after more than nine months on the International Space Station, they came home inside a SpaceX Crew Dragon. The Boeing Starliner that had carried them up the previous June was already gone — its service module burned up in the atmosphere months earlier, taking with it the thrusters NASA investigators most wanted to examine. An eight-day test flight had become the longest unplanned stay in American spaceflight history, and the rescue had come from the only US company with a working crew capsule.

That moment crystallized something NASA officials had been quietly acknowledging for years. SpaceX has held a monopoly on US crewed access to the ISS since Doug Hurley and Bob Behnken splashed down aboard Endeavour in early August 2020, ending a nine-year gap in domestic human spaceflight. More than five years later, with Starliner still grounded, that monopoly has not loosened. It has hardened.

The official plan was never supposed to look like this. When NASA awarded its Commercial Crew contracts in September 2014, the agency split the work deliberately between two providers: Boeing for the CST-100 Starliner, SpaceX for Crew Dragon. Two vehicles, two rockets, two launch pads. Redundancy was the entire point.

The gap that was supposed to close in 2017

Both capsules were supposed to be carrying astronauts by 2017. Crew Dragon’s first operational flight, Crew-1, finally launched in November 2020 — three years late. Starliner’s first crewed flight didn’t lift off until early June 2024, seven years behind schedule, and it ended with NASA deciding the spacecraft was too risky to bring its own crew home.

Since the Wilmore-Williams rescue, every American who has reached the ISS has done it inside a Dragon. Crew-9, Crew-10, Crew-11. Private missions flown by Axiom Space. Even European Space Agency astronauts like Denmark’s Andreas Mogensen and Sweden’s Marcus Wandt have ridden up on Falcon 9. SpaceX now operates a fleet of five reusable capsules — Endeavour, Resilience, Endurance, Freedom, and the newest, Grace, which debuted on Axiom’s Ax-4 mission in 2025. Endeavour, the capsule that flew Hurley and Behnken in 2020, has now made five trips to orbit. The Falcon 9 boosters beneath them are themselves reused, scorched first stages returning to droneships off the Florida coast within minutes of liftoff.

Why the Russian backup quietly disappeared

For decades, the Soyuz was the safety net. From the Space Shuttle’s retirement in July 2011 until 2020, NASA bought seats on Soyuz at prices that climbed significantly over the years. Even after Dragon began flying, NASA and Roscosmos kept a barter arrangement going — a seat-swap so that at least one American and one Russian were always on station, on different vehicles, in case one was grounded.

That arrangement still technically exists. A NASA astronaut launched on a Soyuz in 2025 as part of the seat-swap program. But the political ground beneath it has thinned since February 2022, and the seat-swap is no longer the redundancy NASA can plan a decade around. The only American-built vehicle in the loop is Dragon.

What Starliner still has to prove

Boeing’s capsule isn’t dead, but its path back to flight has slipped repeatedly. Through the first half of 2025 NASA said it had not yet decided whether Starliner’s next mission would carry a crew, and in November 2025 the agency and Boeing settled the question: the next flight, designated Starliner-1, will be an uncrewed cargo run targeted for no earlier than April 2026, retesting the propulsion system that overheated and leaked helium on its way to the station in June 2024. In the same decision NASA trimmed the number of operational crew flights it is obligated to buy from Boeing. The thrusters that failed during docking — five of 28 reaction control jets in the service module — were destroyed when that module burned up during the empty return in early September 2024, which is partly why the investigation has taken so long. The hardware that misbehaved no longer exists.

Even on an optimistic schedule, Starliner’s return to crewed flight has not occurred as of mid-2026, and the regular crew rotations that would let it genuinely share the workload with Dragon sit further out still. The per-seat cost to NASA, under the fixed-price Commercial Crew contract, has been lower than what NASA paid for Soyuz seats in the final years of that arrangement. Boeing has taken significant financial charges against its Starliner program since 2016.

What the lack of alternatives actually means in 2026

It does not mean NASA has no rockets. The agency’s Space Launch System flew Artemis I around the Moon in late 2022, and Orion is built for deep space. But Orion cannot reach the ISS in any operational sense — it’s the wrong vehicle for a low-Earth-orbit rendezvous, and SLS launches cost in the multi-billions per flight. Sierra Space’s Dream Chaser, a winged cargo vehicle, is being prepared for uncrewed resupply runs but is years from a crewed variant.

Blue Origin’s New Glenn flew its first mission in January 2025 and has not been certified for crew. Vulcan, the rocket from United Launch Alliance that Boeing partly owns, is human-rated on paper but has no capsule attached to it now that Starliner uses Atlas V — and Atlas V’s remaining flights are spoken for.

So when NASA says it has no American alternative to Dragon, the agency means it in the narrow, literal sense: there is exactly one US-built, US-launched system today that can take a human being to the International Space Station and bring them home. That system has a single supplier.

The other quiet shift

While Dragon has become essential to crewed access, NASA has also leaned harder on commercial partners across the rest of its portfolio. The Roman Space Telescope built at Goddard is government-built but launches on a commercial rocket. The agency’s experimental aircraft program has begun accepting transferred military F-15Ds rather than buying new chase planes outright. The X-59 quiet supersonic demonstrator is being built by Lockheed Martin under a Skunk Works contract. The shape of NASA in 2026 is an agency that designs, contracts, and certifies more than it builds.

Within that shape, Dragon is not unusual. It is just the most consequential example, the one that touches every astronaut on every mission to the ISS — and the one that exposes the central tension in NASA’s commercial strategy. The agency made a bet that competitive procurement would deliver lower costs and more resilient supply than the old cost-plus model. On cost, that bet has clearly paid off. On resilience, it has not. A two-provider hedge only hedges if both providers actually fly.

What happens after 2030

The International Space Station is scheduled to be deorbited in 2030 or 2031 using a SpaceX-built US Deorbit Vehicle that NASA awarded in June 2024. The capsule that takes the last astronauts off the station will, on current plans, be a Dragon. The vehicle that pushes the station into the Pacific will, on current plans, also be made by SpaceX.

By then, NASA hopes commercial space stations from Axiom, Vast, Voyager Space, and Blue Origin will be in orbit, and the agency expects to buy crew transport to them the same way it buys crew transport to the ISS now — as a service. The architecture that replaces the ISS, in other words, will deepen the commercial-services model that produced the current Dragon dependency rather than retreat from it. Whether more than one provider will be flying crews by 2030 is the question the next four years will answer, and the answer will shape whether American human spaceflight in the 2030s rests on a competitive marketplace or on a single contractor whose business decisions become, by default, national space policy.

That is the deeper stake behind the Wilmore-Williams rescue and behind every Dragon launch since. For now, every American who looks up at the ISS as it crosses the evening sky — a moving point of light brighter than most stars, visible to the naked eye for about five minutes at a time — is looking at a station their country can only reach in one kind of spacecraft, built by one company, launched from one stretch of Florida coast. The redundancy that Congress demanded in 2014 has not been built. The dependency that resulted is now the plan.

The post NASA still has no American-built way to reach the International Space Station except SpaceX’s Dragon capsule — a dependency that has lasted years and shows no sign of ending soon appeared first on Space Daily.

Inside a 140,000-square-foot building in Long Beach that the local aerospace crowd calls Space Beach, circuit boards for spacecraft and defense systems are now coming off the line in a matter of weeks — the same boards that used to take years. The people who run the plant are not claiming the engineers suddenly got faster. They are saying something stranger: there are no longer enough engineers to build the hardware the United States has ordered, and a software agent is now doing the parts a person used to do.

The facility belongs to Voyager Technologies, a Denver-based aerospace and defense company that opened the site on March 12, 2026. Its purpose is narrow and blunt — compress the timeline between a defense-electronics design and a working board, using agentic artificial intelligence to do it.

That single fact cuts against the loudest story being told about AI everywhere else. In most industries the technology arrives as a way to trim headcount. In aerospace and defense it is arriving because the headcount cannot be filled.

The boards that used to take years

Voyager’s Long Beach center runs research, development, and manufacturing across advanced electronics, mission hardware, propulsion, and autonomy systems, SpaceNews reported from the March opening. It is the company’s second major buildout in three months, following the 150,000-square-foot Voyager American Defense Complex that opened in Pueblo, Colorado, in January with a focus on missile defense and tactical munitions.

The man running the defense side is Matt Magaña, Voyager’s president for space, defense, and national security. He grew up in Long Beach and spent close to two decades as a Raytheon executive before joining Voyager in 2024. He describes the old way of building mission electronics in plain terms: it takes years and years, and that is the bottleneck.

The plant’s pitch is that agentic AI can collapse that. Magaña has described printing circuit boards within weeks and months rather than years, using AI to compress the journey from a design to a board headed for orbit. “We’ve got to cut that down to have the speed of relevance,” he told Aviation Week.

Speed of relevance is a military phrase, and it is doing real work here. Voyager is building alongside other Space Beach companies, including Anduril Industries and True Anomaly, in a stretch of Southern California where firms have clustered to stay near the engineering talent and suppliers left over from the region’s older aerospace era.

The robots-on-the-factory-floor story is decades old. What is new at Space Beach is the robot in the engineering office — the one drafting the design, not bolting the part.

Why there aren’t enough people

The shortage is not anecdotal. Clay Mowry, chief executive of the American Institute of Aeronautics and Astronautics, told an audience at the ASCEND conference in Washington that some companies are trying to lift production “by a factor of four,” according to SpaceNews. Firms in the missile-interceptor business, he said, have to scale fast, and there are not enough trained people to put in the jobs — so they are scrambling.

The demand is real and specific. The companies cannot bring in enough trained engineers, software developers, and specialized manufacturing staff to meet the contracts already signed, let alone the expansion the Pentagon now wants. They are all chasing the same small pool of workers fluent in autonomy, machine learning, and systems integration, and that pool is not growing fast enough to match the order books.

The workforce is also aging out. About one-third of aerospace and defense manufacturing and engineering roles are held by workers 55 or older, the AIAA’s Aerospace America reported, citing Deloitte and McKinsey analyses, and the sector’s retirement and attrition rate runs nearly 10 percent above the national industry average. One McKinsey estimate put the cost of that talent drain at up to $330 million for a single mid-sized company.

So the experienced people are leaving faster than they can be replaced, the work is harder to learn than almost any other engineering discipline, and the orders keep climbing. The arithmetic does not close.

A shrinking pipeline

The squeeze sits inside a broader contraction of the technical labor supply. The federal workforce shrank by roughly 220,000 people through November 2025, about a 10 percent cut, according to data analyzed by The New York Times from the Office of Personnel Management — the steepest reduction in decades. Many of those losses landed at civilian agencies that historically fed engineers into defense and aerospace through internships, fellowships, and research partnerships.

Money has been thrown at the gap. Congress added nearly $34 billion above the president’s fiscal 2026 defense request for more than 1,000 research and procurement programs, Roll Call reported, drawing on a database from Taxpayers for Common Sense. The watchdog group has counted more than $134 billion in such program increases since fiscal 2022.

But an appropriation does not produce a qualified engineer, and it does not shorten a test cycle. That is the wall the industry keeps hitting, and it is why a Denver company is standing up a building in Long Beach to let software do the work that hiring cannot fill.

What agentic AI actually does in the engineering office

Agentic AI is not the rule-based automation aerospace plants have used for forty years. Traditional automation handles one narrow, repeating task: a robotic arm welding a seam, a machine running a tolerance check. The agentic version is built to work across the whole production cycle — design iteration, compliance paperwork, supply-chain coordination, production planning — treating them as one connected job rather than a chain of handoffs.

On the floor, that changes who the engineer is. A systems engineer who once shepherded a single program can now oversee several, with the agent drafting the documentation, running the early trade studies, and grinding through the routine compliance work that used to eat hours a day. The engineer becomes a reviewer and a decision-maker instead of a producer of paperwork.

The people selling it are careful to say the humans do not disappear. Magaña has framed the goal as accelerating the cycle time, not removing the engineer from it. The agent is the junior staff that cannot be hired.

The space hardware itself is what makes this hard. A board bound for orbit has to survive launch loads, thermal swings of hundreds of degrees, and a radiation environment that corrupts ordinary electronics. Qualifying that hardware still routinely takes years — a timeline that turns into a problem when commercial operators want a satellite constellation fielded in months and defense customers want resilient systems in place before an adversary closes a gap.

This is where the agent is pointed. It can run thousands of simulation variations in parallel, assemble the qualification documentation, and flag design choices that historically surfaced only after an expensive physical test had already failed. The compression is not in the welding. It is in the thinking that used to happen one engineer at a time.

The accountability problem nobody has solved

The story the plant tells is coherent, and it is also unfinished. When a human engineer signs off on a missile-guidance design, there is a chain of accountability running back through years of training, licensure, and named responsibility. When an agent drafts the compliance package or proposes a design change, that chain gets harder to trace.

The qualification regimes that govern space and defense hardware were built around human reviewers checking human work. Adapting them to artifacts an AI generated — without losing the rigor that keeps an interceptor intercepting and a satellite operating — is a problem the sector has not solved. It is regulatory rather than technical, and it sits in the space between agentic AI accelerating a cycle and quietly defining it.

For now, the shortage is making the decision. The contracts are signed, the deadlines are fixed, and the engineers cannot be hired at the rate the order books demand, so the experiment is running whether or not the verification questions have answers.

Back in Long Beach, the boards keep coming off the line in weeks. The building is new, the talent it was meant to draw on is thinner than it has been in a generation, and the agent in the engineering office is doing the trade studies that a younger engineer, in another decade, would have done by hand. Whether those boards hold up the way years of human review once guaranteed will not be settled in a conference hall. It will be settled in orbit, and on the ranges, on the first programs fast enough to get there.

Every photograph of Earth ever taken from space, from Apollo 8’s Earthrise to Apollo 17’s Blue Marble to Voyager 1’s Pale Blue Dot, descends from a strip of 35-millimetre film pulled from the wreckage of a captured German V-2 rocket in the New Mexico desert in October 1946.

The camera that exposed it was a DeVry motion-picture camera modified by Clyde Holliday at the Johns Hopkins Applied Physics Laboratory. It was not launched on a spacecraft, because no spacecraft existed. It was bolted into a weapon.

On October 24, 1946, V-2 No. 13 rose from White Sands Proving Ground carrying Holliday’s camera above the line now commonly treated as the edge of space. At about 105 kilometres up, it photographed Earth as a curved surface against black sky, one frame every second and a half.

The rocket did not land gently. It came back down on the desert range and was destroyed on impact, but the film cassette survived. When the frames were recovered and developed, the result was the first successful photograph of Earth taken from space.

The date matters because it is often blurred with the better-known V-2 camera flights that followed in 1947 and 1948. The first successful sequence came on October 24, 1946, more than a decade before Sputnik, and long before any human being had seen Earth from orbit.

A weapon repurposed as a camera platform

The V-2 was designed to kill. Wernher von Braun’s team at Peenemünde built it as a long-range ballistic missile, and the Smithsonian National Air and Space Museum describes the weapon as having a range of about 320 kilometres and a one-ton warhead.

More than 3,000 V-2s were fired at Allied targets during the war. The program also consumed forced labour on a horrific scale, with the Smithsonian’s Air and Space Museum noting that at least 10,000 people died in the Mittelwerk production system, more than were killed by the weapon’s deployment.

After Germany’s defeat, American forces shipped captured V-2 parts to New Mexico. White Sands became one of the places where the United States learned how high-altitude rockets behaved, how instruments survived launch, and how useful the upper atmosphere could be as a laboratory.

The U.S. Army’s own history of White Sands places the range at the centre of early American rocket testing, beginning with captured German V-2 technology in 1946. That same test culture opened the nose cones to scientists from the Naval Research Laboratory, the Applied Physics Laboratory, the University of Michigan and other institutions.

Most instruments were there to measure radiation, cosmic rays, solar ultraviolet light or the upper atmosphere. Holliday’s camera did something simpler and stranger. It turned the rocket around, in effect, and made Earth itself the subject.

The camera rode above the Kármán line

The October 24 flight carried a 35-millimetre DeVry cine camera, set to expose one frame every 1.5 seconds. Contemporary accounts identify the launch as V-2 No. 13, fired from White Sands and reaching about 104.6 to 105 kilometres above the desert.

That altitude put the camera just above the 100-kilometre Kármán line, the conventional boundary often used to mark the start of space. Balloons had photographed curvature from high altitude before. Holliday’s camera crossed into a different category.

The flight itself was rough. After engine cutoff, the rocket tumbled, and its spent body eventually struck the range downrange from the launch site. One detailed reconstruction places the impact speed at about 150 metres per second, far below the 500 to 800 metres per second sometimes repeated in loose retellings.

The camera was not simply vaporised. Accounts of the recovery describe Holliday’s camera as found in usable condition except for damage such as the missing lens, while the film cassette preserved the exposed frames. The rocket was gone; the pictures remained.

What the first frames showed

The images were grainy and severe. They showed a bright, curved horizon, black sky above it, and the American Southwest flattened into pale geometry below.

Nothing in the frame looks like the blue planet photographs that later became famous. There are no oceans shining blue, no cloud swirls at global scale, no Moon in the foreground. The power of the image is that it is barely an image at all, just enough evidence to prove that Earth could be photographed from outside itself.

Smithsonian’s account of the flight notes that Holliday stitched the movie frames together into broader views, and that the V-2 photographs revealed the planet against the darkness of space. The Johns Hopkins Applied Physics Laboratory also credits its researchers in 1946 with bolting a 35-millimetre motion-picture camera onto a captured German V-2 and taking the first pictures of Earth’s curvature from space.

Holliday understood the shift almost immediately. In a 1950 National Geographic article, he wrote that the V-2 photographs showed “how our Earth would look to visitors from another planet coming in on a space ship.”

The view before Sputnik

That sentence was written seven years before Sputnik, twelve years before John Glenn orbited Earth, and eighteen years before Apollo 8 carried human eyes around the Moon. The idea of Earth as a planet among planets was already present in a strip of film recovered from military wreckage.

The camera program did not stop with one rocket. Holliday and other teams refined the mounts, lenses and recovery systems, and later V-2 flights produced clearer panoramic images from still higher altitudes, including views that covered enormous stretches of the southwestern United States and northern Mexico.

Those flights helped teach engineers how to design instruments for violent ascent, cold upper air, vibration, spin and impact. The information flowed into the wider American sounding-rocket program, including Aerobee, a smaller and cheaper research rocket that APL developed when V-2s became scarce.

The line from V-2 photography to later space images is not only emotional. It is technical. The recovery procedures, camera housings, telemetry habits and high-altitude test culture belonged to the same early chain that eventually led from sounding rockets to satellites, crewed capsules and planetary probes.

The photographs that followed

A little more than two decades later, Apollo 8 astronaut Bill Anders photographed Earthrise from lunar orbit. In 1972, the Apollo 17 crew took The Blue Marble while travelling toward the Moon.

In 1990, Voyager 1 turned back toward home and made Pale Blue Dot, photographing Earth from about 6 billion kilometres away. Space Daily has covered that image separately in its account of Carl Sagan’s long push for Voyager’s final look back.

Every one of those later images is more beautiful than Holliday’s first frames. They are richer, cleaner, more legible and more famous. But none of them came first.

The first view was black and white, scratched by motion, recovered after impact, and born from a rocket designed for war. Somewhere in that damaged sequence, the desert falls away and Earth curves into darkness for the first time a camera ever proved it could.

The post In 1946, a captured German V-2 rocket launched from White Sands carried Clyde Holliday’s 35-millimetre DeVry motion-picture camera above the Kármán line and returned the first photographs of Earth from space on film recovered after the rocket crashed in the New Mexico desert appeared first on Space Daily.

Apollo 17 was the last time human beings walked on the Moon, but the mission did not behave like an ending. It behaved like a field season. In December 1972, Gene Cernan and Harrison “Jack” Schmitt landed in the Taurus-Littrow valley, drove a battery-powered rover across black lunar dust, and packed 741 rock and soil samples into boxes for the trip home.

The total came to 110.5 kilograms, the largest lunar sample return of the Apollo program.

One of the most arresting pieces of that haul was not a boulder or a glittering crystal. It was orange soil, found near Shorty Crater, made of tiny volcanic glass beads from an eruption roughly 3.64 billion years old.

The mission had gone to Taurus-Littrow partly because planners wanted old highland material and possible signs of younger volcanism on the valley floor. What Cernan and Schmitt found was stranger. The orange glass really was volcanic, but the crater beside it was not the vent that made it.

The last Apollo landing was built for science

Apollo 17 launched from Kennedy Space Center at 12:33 a.m. Eastern time on December 7, 1972. It was the only night launch of the Apollo lunar program, a Saturn V rising in white flame while the last Moon crew rode toward a landing site chosen for rocks, not symbolism.

The crew had three men. Eugene Cernan commanded the mission. Ronald Evans remained in lunar orbit aboard the command module America. Harrison Schmitt, the lunar module pilot, was a professional geologist and became the only scientist to walk on the Moon.

That mattered before the crew ever reached the surface. Earlier Apollo landings had proved that humans could land, work, and return. Apollo 17 was meant to stretch what a lunar expedition could do when the field crew included someone trained to read rocks as a landscape.

NASA’s mission plan sent Cernan and Schmitt to Taurus-Littrow, a valley on the southeastern edge of Mare Serenitatis. The site offered two temptations at once: old material from the lunar highlands and possible evidence of volcanic activity on the valley floor.

They landed the lunar module Challenger on December 11, 1972. Cernan reported that Challenger had landed, then the crew and Mission Control checked the spacecraft carefully in case an emergency liftoff was needed. Only after that did the valley become a workplace.

Taurus-Littrow was a valley full of targets

To the astronauts, Taurus-Littrow was not just scenery. It was a map of objectives. The South Massif, North Massif, Sculptured Hills, nearby craters, rolling boulders, and dark valley floor each held a different possible piece of lunar history.

The mission was one of Apollo’s J-type flights, which meant longer surface stays, expanded science equipment, and a Lunar Roving Vehicle. The rover let Cernan and Schmitt reach stations no walking crew could have covered efficiently in bulky suits.

Across three moonwalks, they spent more than 22 hours outside the lunar module. They drove about 35.7 kilometres in the rover, stopping at geology stations, sampling boulders, scraping trenches, shooting photographs, reading checklists, and loading sample bags.

The rover also made the Moon messier. During the first excursion, Cernan accidentally knocked off the rover’s right rear fender with a hammer handle sticking out from his suit pocket. Without the fender, abrasive dust sprayed over the astronauts, the vehicle, and their equipment.

Mission Control and the crew improvised a repair using onboard maps, clamps, and tape. It was not elegant, but it worked well enough to keep the dust under control during later drives.

The orange soil was real, but the first explanation was wrong

The most famous discovery came during the second moonwalk near Shorty Crater. Schmitt saw orange material in the soil and called attention to it immediately. On a grey world, colour was not a small detail.

Cernan and Schmitt sampled the orange material and nearby black soil. The discovery seemed, at first glance, to fit one of the mission’s big hopes: finding evidence of relatively young volcanic activity in the Taurus-Littrow region.

The truth was more complicated. Later study showed that the orange and black material consisted of volcanic glass beads, formed in a fire-fountain eruption about 3.64 billion years ago. The melt came from deep inside the Moon, roughly 400 kilometres below the surface.

Shorty Crater, however, was not the volcanic vent. It was an ordinary impact crater that happened to expose older volcanic glass. The bright colour was real. The easy story was not.

That is why Apollo 17 still matters to lunar science. The mission did not just collect souvenirs from the last human visit. It returned samples that forced geologists to separate what the Moon looked like from what had actually happened there.

The samples kept speaking after the astronauts left

The Apollo 17 collection included basalts, breccias, highland crustal rocks, rare deep-crust materials, rake samples, core samples, and soil from multiple stations. The 741 individual samples gave laboratories on Earth a physical archive of Taurus-Littrow.

Some rocks helped scientists study ancient basin-forming impacts. Others recorded mare volcanism, when lava once filled low areas of the Moon. The orange glass preserved a more explosive story, with droplets frozen from molten material thrown out billions of years ago.

The crew also drilled a deep core reaching material from about three metres below the lunar surface. That core let researchers examine layers that had been shielded from the most recent surface exposure.

Half a century later, Apollo samples are still being reanalysed with instruments the original mission teams did not have. The rocks Cernan and Schmitt packed into boxes in 1972 remain active scientific material, not relics.

That is why new work on Apollo material keeps appearing. A sample can sit quietly in storage for decades, then meet a better microscope, a more precise mass spectrometer, or a new question about the Moon’s interior.

Scientists are still pulling new chemistry out of Apollo 17 material today, including from samples returned in 1972 and preserved for later generations of instruments. Recent analysis of Apollo samples has continued to reveal hidden details about the Moon’s mantle.

The suits made fieldwork feel mechanical

For all the grandeur of the photographs, Apollo 17 geology was hard physical labour. Cernan and Schmitt worked in pressurized suits, sealed helmets, stiff gloves, and portable life-support backpacks. Every sample bag, rake stroke, core tube, and camera frame had to pass through machinery wrapped around the body.

Cernan’s flown A7-LB suit is now preserved by the Smithsonian. It was the last spacesuit worn on the lunar surface, with the red commander stripes visible in the images that still define Apollo 17.

Inside that suit, a geologic field stop became a sequence of constrained movements. Bend carefully. Grip through gloves. Balance in one-sixth gravity. Keep track of the sample number. Keep dust out of the wrong places. Describe the rock clearly enough for scientists on Earth to follow the work.

Schmitt’s presence changed the texture of the mission. He could look at a rock, a slope, or a patch of soil and narrate what made it geologically interesting. Cernan handled the rover, equipment, drilling, navigation, and command decisions while Schmitt kept reading the valley.

That partnership is the centre of Apollo 17. One astronaut brought the instincts of a Navy pilot and mission commander. The other brought the eye of a field geologist. Taurus-Littrow needed both.

There is a thoughtful video by Justin Brown that examines why difficult, quiet work can feel so different from work that brings constant feedback, which gives the Apollo 17 surface record a useful modern echo without changing what the mission actually was.

The final footprints were not the final experiment

Before leaving the surface, Cernan and Schmitt parked the rover so its television camera could watch Challenger lift off from the Moon. The rover stayed behind, along with the descent stage, tools, experiment hardware, footprints, wheel tracks, and the disturbed grey dust around the work sites.

Cernan was the last person to climb the ladder from the lunar surface. That fact gives Apollo 17 its emotional weight, but it can also flatten the mission into a farewell scene. The better way to understand it is as a scientific expedition that happened to be the last one.

The final Apollo astronauts also left objects that still connect the Moon to Earth. Earlier Apollo crews and Apollo 17 left retroreflectors that scientists have used to bounce laser pulses off the lunar surface, a continuing measurement of the Earth-Moon distance and the Moon’s slow movement away from us.

Those retroreflectors are still part of a live experiment. So are the rocks, in a different way. Every time a sealed Apollo 17 sample is opened for a new generation of instruments, the mission extends beyond December 1972.

Cernan also left a private mark for his daughter Tracy in the lunar dust, a small human gesture beside the official science and hardware. The initials he traced into the regolith are likely still there, not because they were protected, but because the Moon has no wind or rain to erase them.

The rover is still in Taurus-Littrow. The orange glass is on Earth. The footprints and wheel tracks remain in dust that has not felt weather since the astronauts lifted away. Apollo 17 ended as a flight, but as a field record it is still open, waiting in rock boxes, transcripts, photographs, and a valley no human has crossed since.

The post In 1972, Apollo 17 carried the only scientist to walk on the Moon into Taurus-Littrow, where a broken rover fender, 741 samples, and orange volcanic glass from 3.64 billion years ago turned the final lunar landing into a geology field trip appeared first on Space Daily.

On 9 June 2026, inside a room at NASA’s Johnson Space Center in Houston, the agency named the four people who will fly Artemis 3 — and one of them was not American. Italian astronaut Luca Parmitano was introduced as the mission’s pilot, the first European Space Agency astronaut ever assigned to an Artemis crew. He will sit in the right-hand seat of an Orion spacecraft partly built in Europe, on a flight that will not, in fact, land on the Moon.

Parmitano is not a symbolic pick. He has logged 366 days in orbit across two long-duration stays on the International Space Station, performed six spacewalks totalling more than 30 hours, and commanded Expedition 61 in 2019, the first Italian to do so. During a 2013 spacewalk, water from a failed cooling system flooded his helmet and nearly drowned him before he groped his way back to the airlock blind. NASA put a near-fatality survivor and a former station commander in the pilot’s seat.

That detail is the tell. A seat this visible is never just a seat.

A pilot’s chair, not a thank-you note

Within hours of the announcement, ESA Director General Josef Aschbacher made the subtext explicit. Parmitano’s assignment, he told reporters, was the first step in a wider negotiation — one aimed squarely at getting a European astronaut onto the lunar surface, not merely into Earth orbit. He noted the seat had not been settled even a couple of weeks before the announcement, a sign of how live the bargaining still is. The full exchange was reported by SpaceNews.

ESA’s exploration chief, Daniel Neuenschwander, framed it as Europe playing two roles at once: supplying both a senior astronaut and the propulsion module that drives Orion. For Europe, the crew slot matters less for what Parmitano does in orbit than for what it establishes. Once a European has flown an Artemis mission, excluding Europeans from the next ones gets politically expensive. The ESA announcement made the partnership framing official.

The real prize sits further down the manifest. ESA wants boots on the regolith, and it is treating Artemis 3 as the down payment.

Why Gateway’s collapse changed the math

The bargaining became urgent because the structure Europe had built its lunar plan around stopped existing. On 24 March 2026, NASA acting administrator Jared Isaacman announced the agency would pause the Lunar Gateway “in its current form” and redirect effort toward infrastructure on the Moon’s surface. The decision, delivered at NASA’s Ignition event and reported by The Register, sidelined the small lunar-orbit station that had anchored the program’s international architecture.

That broke a carefully negotiated European position. At its November 2025 ministerial conference, ESA had announced three guaranteed Gateway seats, assigning them to astronauts from Germany, France and Italy, with Germany flying first. Gateway was the vehicle — politically and literally — for putting Europeans into deep space on a recurring schedule.

When NASA shelved it, those three seats lost their destination. Canada’s contribution took a hit too: the Canadarm3 robotic arm had been built for a station that was no longer the centerpiece.

NASA had already reshuffled the flight plan in February, demoting Artemis 3 from the first landing to a 2027 test flight in low Earth orbit. The Orion crew will rendezvous and dock with prototype landers from Blue Origin and SpaceX, rehearsing the choreography for Artemis 4, now the first crewed South Pole landing, targeted for 2028.

So Europe arrived at the table with new currency to spend and a shorter clock to spend it on.

The hardware Europe brings to the table

Europe’s strongest card is one it already holds. The European Service Module, built by Airbus with Thales Alenia Space, supplies Orion’s main propulsion, power, water, oxygen and thermal control. Without it, the capsule does not fly. Artemis 3 will use ESA’s third such module — a dependency described on Airbus’s own program page. That is leverage that needs no negotiating; it is simply true.

The newer offers are surface-oriented. Aschbacher named several chips ESA is willing to play: cargo delivery via the Argonaut lunar lander, which can put up to 1,500 kg on the surface from the early 2030s; communications and navigation from the Moonlight satellite constellation; plus rovers, surface robotics, and the option of returning cargo from the Moon.

Argonaut and Moonlight are the kind of infrastructure NASA does not currently fund itself. That is precisely why ESA is dangling them.

The pitch is to bundle existing dependency and future capability into a package that is awkward to refuse.

A partner whose own schedule is slipping

Europe is negotiating with a program whose timeline keeps moving. The two landers that Artemis 3 will practice docking with are both behind. SpaceX has not yet demonstrated orbital propellant transfer, a prerequisite for the Starship lunar variant to reach the Moon with enough fuel to land. Blue Origin is still working through development on its Blue Moon lander.

Neither company has published a firm date for clearing those hurdles.

The Gateway decision was itself partly a response to ballooning costs and slipping schedules across Artemis. Some critics of the program argued the restructure was overdue. The paradox for NASA is that simplifying the architecture left it with fewer assets to trade, at the same moment it needs partners more.

That asymmetry is what gives a mid-sized agency room to push.

What a first European seat sets in motion

Three concrete markers will show whether ESA’s play is working before the year is out. Whether NASA commits to additional European Service Modules for later flights. Whether Argonaut wins a formal role in the revised surface-logistics plan. And whether any European astronaut is named to an actual landing mission rather than an orbital test.

The calendar is filling in already. France is hosting an international space summit in Paris in September, and ESA holds its next ministerial conference in December — the meeting where money and commitments get fixed. Aschbacher has flagged both as moments where the lunar question gets pressed.

For now, the fact on the manifest is fixed. A man who once felt water rising over his eyes inside a sealed helmet, 400 kilometres above the planet, will ride the next Orion into orbit as its pilot. He will not step onto the Moon on this flight. But the chair he occupies is the one Europe intends to keep occupying — and somewhere in a meeting room in Paris this autumn, that is the argument his name is already making for him.

The post On June 9, 2026, NASA named Italian astronaut Luca Parmitano as pilot of Artemis 3, making him the first European ever assigned to an Artemis crew — and within hours ESA’s director general framed the seat not as a courtesy but as the opening move in a negotiation to put a European on the surface of the Moon appeared first on Space Daily.

As NASA prepares for humanity’s return to the Moon, researchers at Texas A&M University are exploring how the same material could become a key building block for the first permanent settlements beyond Earth.

The Moon’s surface is surprisingly unlike anything we would consider soil on Earth. Instead, it is covered by a fine powder of pulverized rock and jagged glass that slips into every gap, grinds through seals and gaskets, and exists in a vacuum exposed to intense radiation and extreme temperature swings capable of bending steel. Yet researchers at Texas A&M University see opportunity rather than obstacles in this harsh environment.

Scientists refer to this material as lunar regolith, and it is considered one of the greatest challenges to long-term human habitation beyond Earth.

As NASA advances plans for a permanent human presence on the Moon through its Lunar Innovation Park initiative, Texas A&M researchers are developing technologies designed to transform the lunar surface into a foundation for future settlements.

“We are moving past the era of ‘flags and footprints,’” said Dr. Patrick Suermann, professor of construction science and retired U.S. Air Force lieutenant colonel in a statement. “We have to stop thinking like explorers and start thinking like settlers.”

Money as a Hurdle 

Arguably, the greatest challenge facing lunar construction may not be engineering, but cost. Transporting materials from Earth remains extraordinarily expensive, with estimates ranging from roughly $1 million to $1.3 million per kilogram delivered to the Moon. As a result, researchers are increasingly focused on utilizing resources already available on the lunar surface rather than transporting materials from Earth.

“The future depends on building infrastructure from resources already on the moon,” explained Suermann.

“The high cost of shipping to the moon is the million-dollar problem,” Suermann said. “Every time you can cut the mass of a payload, you save a fortune. That’s why the future depends on building infrastructure from resources already on the moon.”

Helping advance that vision is Dr. Robert Ambrose of the Texas A&M Space Institute, located near NASA’s Johnson Space Center in Houston. The institute has received $200 million in support from the Texas Legislature.

“One of the most exciting features of the 240-acre facility is it’s two-and-a-half acre testing areas: one replicating the surface of the moon, the other Mars,” says Suermann.

These facilities allow researchers to evaluate robotic systems, autonomous vehicles, and construction technologies under conditions similar to those expected during future lunar and Martian missions.

Meanwhile, the university’s Construction Automation, Safety and Education (CASE) Lab is exploring how humans and machines can collaborate in extreme environments. Led by Dr. Gilles Albeaino, the lab focuses on mixed-reality technologies and semi-autonomous robotic systems capable of performing construction tasks on the Moon.

“On the moon, construction operations will depend on semi-autonomous robotic systems,” Suermann said. “The CASE lab is leading research into how humans and machines can work together in environments where humans can’t safely do everything themselves.”

“Every tool matters. Every ounce of material you ship matters,” added Suermann. “So, the question becomes: how do you use the environment itself as your supply chain, and how can you augment machines to become your partner in austere environments?”

Arctic to Afghanistan

Suermann’s experience combines two worlds: military service and construction science. Before joining Texas A&M in 2017, he served in the U.S. Air Force, deploying to remote locations that included Afghanistan, Guam, and Greenland.

Those experiences operating in challenging and isolated environments continue to inform his thinking about future lunar settlements.

“My experiences in serving the U.S. Air Force were formative and transformative,” Suermann said. “It taught me a great deal about construction, and that what can go wrong will go wrong.”

It shows, to me, that lunar regolith isn’t too dissimilar from the terrain we have here on Earth,” Suermann adds. “At the end of the day, construction is construction.”

Should We Develop on the Moon?

The broader question remains whether humanity should be expanding its footprint beyond Earth at all. While plans for lunar settlements continue to advance, critics point out that many environmental, political, and social challenges remain unresolved here at home.

As governments and private companies invest billions into space infrastructure, some argue that humanity must carefully consider how development beyond Earth aligns with priorities on our own planet. Others contend that technologies developed for lunar habitation could ultimately provide benefits back on Earth, helping address challenges ranging from resource management to sustainability.

Could consciousness exist in alien life forms that look nothing like us? Could it even appear in machines? According to a new paper by philosophers Eric Schwitzgebel of the University of California, Riverside, and Jeremy Pober of the University of Lisbon, the answer may be yes. The researchers argue that consciousness is probably not limited […]

Astronomers have discovered a powerful “galaxy-killing wind” in the early universe that may help solve one of the biggest mysteries in modern astronomy: why so many massive galaxies stopped forming stars much earlier than scientists expected. The discovery suggests that some young galaxies grew rapidly and then died just as quickly, not because of exotic […]

It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich […]

Astronauts selected for NASA’s Artemis missions are traveling to outer space in style, the American space agency has revealed.

On June 7, Axiom Space and fashion empire Prada showcased their Liquid Cooling and Ventilation Garment (LCVG), designed to be worn by astronauts inside the Axiom Extravehicular Mobility Unit (AxEMU) spacesuit. 

The unveiling of the new garment by Prada and Axiom Space took place at Prada’s SoHo location in Manhattan just days before the announcement of the Artemis III crew, according to the New York Times fashion desk. With black-clad waiters circulating champagne and healthy juices through the Rem Koolhaas-designed venue, the intersection of fashion and space exploration was once again on full display.

 

“The future of space exploration will not be built by any one entity alone, and our partnership with Prada is proof of that,” said Dr. Jonathan Cirtain, Axiom Space CEO and President, in a statement.

“By bringing together the best in both aerospace engineering as well as luxury craftmanship and advanced product development, we have developed a garment that neither company could have created independently, and that is exactly the kind of cross-industry thinking that will define the next era of human spaceflight,” Cirtain added. 

Some might be surprised to learn this is not the first time NASA has collaborated with a fashion house. The first modern spacesuit was designed and crafted by a group of international designers at the Latex Corporation (ILC). In the 1960s, this company was best known for manufacturing bras and girdles.

Notably, a version of its A7L spacesuit was worn by Neil Armstrong during the Apollo 11 mission. Designers developed the A7L to protect astronauts from the harsh conditions of space and the lunar surface.

The suit was constructed using materials such as neoprene, Beta cloth—which helped protect astronauts from extreme temperatures—and aluminized Mylar. Overall, it was a highly complex, multilayered design.

The new LCVG collaboration draws on Prada’s expertise in knitting, craftsmanship, and advanced design. The resulting garment is a next-generation system developed using sophisticated 3D modeling techniques.

The suit is designed to maintain cooling and ventilation while remaining comfortable during spacewalks lasting up to eight hours. Thanks to its high-performance materials, it can also be worn repeatedly during long-duration missions.

“When we unveiled the AxEMU, we announced that the collaboration between Prada and Axiom Space would continue beyond that first milestone,” said Lorenzo Bertelli, Prada Group Chief Marketing Officer and Head of Sustainability, in a statement. 

“Today, we are proud to present a new achievement born from the unique combination of Axiom Space’s pioneering expertise and Prada’s know-how in design, patternmaking, and advanced materials, ahead of humanity’s return to the lunar surface,” Bertelli added.

In 2024, Axiom Space and Prada unveiled the AxEMU’s outer layer, designed to withstand the harsh conditions of the lunar South Pole. Their latest collaboration on the Liquid Cooling and Ventilation Garment builds on that partnership, focusing on astronaut comfort, thermal regulation, and reliability inside the spacesuit.

“We look forward to continuing this collaboration with Axiom Space, pushing boundaries and exploring new frontiers together,” adds Bertelli.

The LCVG keeps astronauts cool during spacewalks by circulating chilled water through tubes woven into the garment, removing body heat and venting it through the spacesuit. It also delivers fresh oxygen and removes carbon dioxide, helping astronauts remain safe and comfortable in the harsh environment of space.

“Every minute astronauts spend outside their vehicle, the LCVG is working to keep them safe,” said Russell Ralston, Axiom Space Senior Vice President of Spacecraft Development.

“It manages their thermal environment, supports their breathing, and does it all while they’re pushing their bodies to the limit,” Ralson added. “The work we have done with Prada has taken that capability to a level we could not have achieved alone.”
