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.

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.

Apollo astronauts trying to rest on the way to the Moon kept noticing the same thing in the dark. With the cabin lights down and their eyes adjusted, they saw brief flashes and streaks of light, dots and lines that no one else could see and that were not there in any ordinary sense. The cause, worked out over the missions that followed, was cosmic rays from deep space passing through the visual system. The broad cause is now well supported, even if the exact biophysics of how a passing particle turns into a flash of light is still not fully pinned down.

The flashes are an example of a phosphene, a sensation of light produced by something other than light entering the eye.

In this case, the something was radiation.

What the astronauts saw

The reports began on Apollo 11. After a period of dark adaptation, with eyes open or closed, crew members saw flashes they described as pinpoints, thin streaks, or small clouds of light. They were almost always colourless. They came at a rate of roughly one-half to two a minute, often enough to be a distraction when someone was trying to sleep.

This was not confined to one crew or one flight. Flashes were reported across the Apollo missions, and later by astronauts on Skylab, on Mir, and on the International Space Station. The phenomenon even had a kind of forecast. As early as 1952, the biophysicist Cornelius Tobias had suggested that people exposed to cosmic radiation in space might see exactly this sort of thing, and the team that investigated the Apollo reports traced them back to that idea.

How they tied it to cosmic rays

Suspecting a cause and demonstrating it are different tasks. To test whether the flashes really were caused by particles passing through the head, the Apollo 16 and 17 crews carried a device called the Apollo Light Flash Moving Emulsion Detector, worn on the head during the coast to and from the Moon. It used stacked photographic emulsion to record the tracks of charged particles, so that the path of a particle could be matched against the moment an astronaut reported a flash.

The numbers were small but telling. The detector was worn for about an hour on each of the last two Apollo missions. On Apollo 17, seventeen flashes were reported during the session, and two of them were matched to heavy cosmic-ray nuclei passing through an eye. Combined with the geometry of the eye and statistical modelling, that was enough for the investigators to attribute the flashes to cosmic rays. Ground experiments pointed the same way: when volunteers had their dark-adapted eyes exposed to beams of heavy ions, they saw comparable flashes.

What is still uncertain

The confirmed part is that cosmic rays cause the flashes. The unconfirmed part is the step in between, the biophysics of how a single fast particle produces a perceived point of light. Several mechanisms have been proposed, and more than one may contribute.

The leading idea is that the particle ionises tissue directly in the retina, stimulating the light-sensing cells or the neurons behind them as it passes through. This fits the ground experiments, where heavy ions produced flashes at intensities too low for any light to have been generated. A second idea is Cherenkov radiation: a particle moving through the clear jelly of the eye faster than light moves through that medium emits a faint glow, real photons generated inside the eye itself. The trouble is that Cherenkov light should look bluish and diffuse, and most astronauts described sharp white dots and streaks, which do not match. A third possibility is that some flashes come from particles striking the optic nerve or the visual centres of the brain, bypassing the eye altogether.

Decades on, reviews of the phenomenon still describe the specific mechanism as undefined, and note that the effects on the different parts of the visual system have not been fully separated.

The cause is well established; the wiring is not.

Why it still matters

On Earth’s surface, we are mostly shielded from this by the atmosphere and the magnetic field. In low Earth orbit the shielding is reduced but not gone, which is why astronauts on stations such as Mir and the ISS have also reported the effect. The Apollo crews saw the flashes more strongly still because they left that protection behind, travelling beyond the magnetosphere. The flashes were, in effect, the radiation environment of deep space made briefly visible inside a human head.

That is why they are treated as more than a curiosity. They are a perceptible sign that high-energy particles are passing through the body, the brain included, and the same radiation is a serious concern for long missions beyond Earth. On the International Space Station, experiments have used the visual system as a way to study how cosmic radiation affects the central nervous system. For a crew bound for Mars, who would spend months outside the magnetosphere, the dose to the brain over that time is one of the open problems of the trip.

What to watch

The people who travel back to lunar distance under Artemis and later missions will almost certainly see the flashes again. They will also carry better instruments and a sharper reason to use them. Pinning down how the flashes are produced would be a small result. Understanding what months of that radiation does to the brain behind the eye is the one that matters.

The Apollo astronauts who tracked Moon dust back into their cabin kept filing the same odd report. Fresh lunar dust, they said, smelled like spent gunpowder. The impression was immediate, and it was reported by multiple crews. Yet the smell never survived the trip home. By the time the samples were opened in laboratories on Earth, they no longer smelled like gunpowder, and more than fifty years later there is still no settled account of what the astronauts were smelling up there.

The puzzle is real, but it is narrower than it sounds. A good deal is known about why lunar dust is chemically strange. What is missing is the specific link between that chemistry and the smell.

What the astronauts actually reported

The descriptions are unusually consistent, and unusually specific. Harrison Schmitt, the geologist on Apollo 17 and the only trained scientist to walk on the Moon, said the instant impression was of spent gunpowder, not something metallic or acrid. He even noted the timing: about seven minutes passed between the start of repressurising the lander and his first remark about the smell.

Gene Cernan, his crewmate, reached for the same comparison. Buzz Aldrin, on Apollo 11, described it a little differently, closer to burnt charcoal, or wet ashes from a fireplace. John Young, on Apollo 16, went further than smelling it and reported that it did not taste half bad.

One detail matters for what follows. The astronauts were careful to say burnt gunpowder, the smell after firing, not the smell of the powder itself. The two are not the same.

Why it vanished before Earth

The most useful clue is the disappearance. There are hundreds of kilograms of lunar material in the curation lab at NASA’s Johnson Space Center in Houston, and it does not smell of gunpowder. Gary Lofgren, a NASA geologist who has handled the dusty rocks directly, sniffed them and reported plainly that they do not smell like gunpowder.

The astronauts were not imagining it. The accepted reading is that the dust was, in the word researchers use, pacified. Whatever produced the smell was a reaction that happened once, when the dust first met the air inside the cabin, and was finished long before the samples reached Earth. A smell that depends on a one-time reaction cannot be bottled and shipped.

The leading explanation, and where it stops

The reason fresh lunar dust reacts at all comes down to where it has been. The surface of the Moon has no air and no weather. For billions of years its dust has been broken down by micrometeorite impacts and bombarded by the solar wind, producing extremely fine grains with fresh, raw surfaces and, in many of them, tiny specks of metallic iron embedded in glassy coatings. Surfaces like that are chemically hungry. They carry what chemists call dangling bonds, unsatisfied bonds left exposed because the dust has never had air to react with.

Bring that dust into a cabin filled with oxygen and a little moisture, and those surfaces oxidise quickly. The reaction is a slow form of burning, too gradual for smoke or flame, and it is the most popular candidate for the smell. Schmitt himself guessed as much at the time, suspecting his nose was responding to unsatisfied bonds of the kind found in both fresh dust and just-fired gunpowder.

This is a hypothesis with broad support, not a proven result. No instrument sampled the cabin air, so the actual molecules responsible were never identified. The gunpowder comparison is an association in the human nose, not a statement about shared chemistry. Other ideas have been raised over the years, including sulphur-bearing minerals in the dust and volatiles implanted by the solar wind. None has been confirmed, because the evidence that would settle it evaporated, in effect, during the flight home.

Why this is more than a curiosity

The smell is a footnote.

The reactivity behind it is not.

The same properties that may have produced the odour, the abrasive shape of the grains and their reactive surfaces, make lunar dust a serious problem for people and equipment. It clings to everything, works its way through seals, and is fine enough to be inhaled deep into the lungs. Dust that got into the Apollo cabins left crews with eye, nose and throat irritation, an effect NASA came to call lunar hay fever, with Schmitt’s reaction the best documented. Reviews of lunar dust as a hazard link its reactive surfaces and iron content to the way it interacts with human tissue.

That has turned an Apollo-era anecdote into a present-day engineering requirement. For NASA’s Artemis programme, and for the commercial missions intending to operate on the surface for more than a few days, dust handling is now a standing line item: cabin filtration, suit design, airlock procedures, and medical monitoring all have to account for a material whose chemistry was barely understood when the first samples came home.

What to watch

The next people to bring Moon dust into a sealed cabin will arrive with instruments the Apollo crews did not have, and with reason to use them. Whether anyone finally captures the cabin chemistry, and identifies what the astronauts were smelling, is one of the smaller questions Artemis could answer. The larger one, how to live and work in the stuff without it harming lungs and hardware, is the reason the answer would be worth having.
