NASA released more than 800GB of science data, images, and video from the Artemis II mission this week, posting the material on a site called Artemis II: Sights & Sounds of Science. The archive covers the agency's effort to return humans to the Moon and gives the public an inside look at a historic spaceflight. It includes more than 11,000 photos and videos, over 8.5 hours of audio, and images annotated by the crew.
Among the materials are crew-marked pictures, including one that identifies where the astronauts saw impact flashes on the dark side of the Moon. Footage in the collection shows the Artemis II team describing those flashes to the ground team in Houston. Impact flashes have been observed before, but the ones seen on the lunar dark side may have been the faintest ever witnessed with the human eye, and the clip captures the crew's excitement.
NASA paired the release with three documents meant to help people work through the raw material. They are the Artemis II Preliminary Lunar Science Report, the Artemis II Lunar Science Operations Report, and the Artemis II Lunar Science Data User Guide. Together with the media archive, the documents give researchers and the public a way to dig into the mission's findings.
The size of the dump sets it apart from earlier releases from the Artemis program. More than 11,000 photos and videos, plus hours of audio, represent a scale of public access that NASA has not previously offered for this effort. The agency's Artemis program is its attempt to return humans to the Moon, and the trove arrives as the program continues toward later missions.
The release is aimed at a broad audience, from scientists who will use the documents and data to members of the public who want to see and hear the mission for themselves. All of the material is available through the Sights & Sounds of Science site. The archive remains the most complete public record of the mission so far.
