If you thought you’d seen all there is to see from the Artemis II mission, you’re wrong. This week NASA posted over 800GB worth of science data, images, and videos on the Artemis II: Sights & Sounds of Science site. The archive includes over 11,000 photos and videos, over 8.5 hours of audio, and crew-annotated images, such as the one marking where they saw impact flashes on the dark side of the Moon. Together, they offer an unprecedented view inside a historic space mission.
One of the more exciting reveals was footage of the Artemis II team telling the ground team back in Houston about its observation of impact flashes. Impact flashes have been seen before, but these ones on the dark side of the Moon could have been the faintest observed with the human eye, and everyone’s excitement is palpable in the clip.
Alongside the dump, NASA also released a trio of documents that help supplement the trove of unfiltered data. That includes the Artemis II Preliminary Lunar Science Report, the Artemis II Lunar Science Operations Report, and the Artemis II Lunar Science Data User Guide.
