Artemis 2 astronauts reported five flashes on the Moon during an eclipse after their flight around the far side of the Moon.
Hear what astronauts saw, see their hand-marked map, and why NASA confirmed impact flashes even though no photograph captured them.

What this film does and does not claim: NASA's Artemis II Preliminary Lunar Science Report (released 7 October 2026) says the crew formally reported five impact flashes during the eclipse of 7 April 2026 (UTC), likely the faintest ever seen by human eyes, from rocks estimated at several centimetres across. No photograph or video shows any of them: one Orion camera recorded about two minutes of the eclipse and detected none, and the report does not establish why. NASA treats the sightings as a lower bound on impacts during a quiet period, not a fixed rate. The crew audio is NASA's own recording; captions follow the report's transcript. The flash map is the crew's own ink on a NASA visualisation. Nothing in this film shows a flash.
