Real Earthset Video From 400,000 Km Away | Artemis II Astronaut's iPhone Video from Moon's Far Side

The video was shot by NASA Commander Reid Wiseman during the Artemis II mission. He used his personal iPhone. The reason was entirely practical: the iPhone was the only device small enough to fit against the docking hatch window at the correct angle to capture the view. NASA cameras and professional lenses are built for specific, planned shots. This was not a planned shot. This was a man who saw something extraordinary through a window and grabbed the only thing in his pocket.
He pressed the phone directly to the glass. The geometry of the hatch simply did not allow anything larger to fit at that angle, and there was no time to improvise a setup. One window, one moment, one device that happened to fit.
He knew he had one chance
Wiseman noted that this was a once-in-a-lifetime moment — and he described it as feeling like watching a sunset at the beach, but from the most remote vantage point any human being has occupied since the Apollo era. The emotional weight of that description matters, because it explains the decision. You do not stop to find better equipment when something like that is happening in front of you. You film it with what you have.
What about the zoom and image quality?
The iPhone's 8x zoom, Wiseman noted, is roughly equivalent to what the human eye naturally perceives at that distance and scale. This means the video is not artificially compressed or enlarged — what you see on screen is genuinely close to what he saw with his own eyes in that moment. The computational photography system inside the iPhone — the same software that processes an ordinary photo taken at a dinner table or on a street corner — was running in real time approximately 400,000 kilometers from Earth, automatically adjusting exposure, stabilization, and color balance under conditions it was never designed for.
The fact that the footage came out as clean and stable as it did is itself remarkable. There was no manual adjustment, no post-processing on board. The phone did what it always does, except this time the subject was Earth disappearing behind the Moon.
What was Christina Koch doing at the same time?
While Wiseman filmed on his iPhone, fellow astronaut Christina Koch was documenting the same event using a 400mm professional lens with bracket exposure shooting — a technique where multiple frames are captured in rapid succession at different exposure settings. The purpose is to preserve detail simultaneously in the brightest areas, such as the sunlit lunar surface, and the darkest areas, such as the shadow regions and the blackness of space. The resulting images have a resolution and dynamic range that no smartphone camera can match. Koch's photographs show individual weather systems on Earth's surface, the spiral structure of storm cells, the sharp boundary between ocean and cloud cover, and the thin atmospheric halo glowing at the planet's edge.
The two recordings — Wiseman's iPhone video and Koch's professional photography — are not competing versions of the same moment. They are complementary. One shows you what it felt like. The other shows you what was actually there.
What did they film, and why does it matter?
They filmed Earthset — Earth moving behind the lunar limb and disappearing completely from view. At the start of the sequence, Earth fills a significant portion of the window. You can see weather systems, the terminator line where day transitions into night curving across the surface, and the atmospheric halo tracing the planet's edge against the black behind it. The scale at this point is roughly comparable to how Earth looks from the International Space Station at around 400 kilometers altitude.
But Orion does not stop. By day six, when the spacecraft reaches the Moon's gravitational sphere of influence, Earth in the window is no longer a world you are above. It is an object you are looking at from a distance — the way you look at the Moon from your backyard. The entire planet fits comfortably in the frame with room to spare.
Then, at the hatch window, Earth slips behind the lunar limb. The atmosphere thins to a razor-thin arc of blue at the planet's edge. Then nothing. Earth set. The first time any human being had watched this happen since the Apollo program in the late 1960s — and one of them filmed it on a phone he pulled from his pocket.
