NASA released more than 800 gigabytes of Artemis II lunar science data, including more than 11,000 images and 8.5 hours of crew audio

Three astronauts circled flashes of light on an image of the eclipsed Moon in blue, green and red, and that annotated picture now sits in a public archive alongside thousands of others from the Artemis II flight. NASA opened the files on October 7, 2026, and the numbers are large: more than 800 gigabytes of lunar science data, more than 11,000 full-resolution images and 8.5 hours of recorded crew observations.

Wiseman marked in blue, Glover in green and Hansen in red. Several circles probably show the same impact flashes seen at different moments.

The agency’s announcement from Public Affairs Officer Molly Wasser describes the release as the first planetary science dataset captured primarily by humans in more than half a century. The images and video come from the crew’s handheld cameras and from cameras mounted on the Orion spacecraft, and the audio carries the astronauts’ spoken observations of the lunar surface, recorded as the crew looked out at the surface. Some of the material had never been published before. NASA astronauts Wiseman, Glover and Christina Koch flew with Canadian Space Agency astronaut Hansen, and the lunar flyby happened on April 6, 2026, a date that anchors every timestamp in the archive. The post also notes that the dataset is meant for the global science community and the public, not for mission insiders alone.

Planetary Data System bundles and the missing SPICE set

Everything sits in NASA’s Planetary Data System, the public archive for the agency’s planetary missions. The Artemis II page at the PDS Geosciences Node splits the material into five bundles: crew camera, Orion camera, mission audio, a mission bundle holding documents and environmental data, and a SPICE bundle of observation-geometry data. Each carries its own DOI, so researchers can cite a single bundle rather than the whole release.

The page also carries an important qualification. It calls the October 7 posting the first delivery, and it says the SPICE bundle is not yet available at the node that hosts it, with release expected in the near future. That is why the files are best described as a large first tranche, not a complete record of the mission. The same page notes that the environmental coverage is partial too, since only two loggers are described, so researchers hoping to reconstruct the full thermal history of the cabin will find a sample of it rather than a continuous map.

Nikon bodies, Orion cameras and cabin loggers

The crew camera bundle holds frames from handheld Nikon D5 and Nikon Z9 cameras, shot at the Moon, at Earth and into deep space. The Orion bundle draws on the spacecraft’s solar array wing cameras, a cabin camera, the optical navigation camera and the docking camera. The audio bundle includes crew observations recorded on portable computing devices, the voice loops between Orion and Earth, transcripts and the crew’s own annotations.

The mission bundle is the odd one out among the five, because it mixes paperwork with instrument readings. Besides documents such as the Open Science and Data Management Plan and the Lunar Targeting Package, it holds readings from two small data loggers that tracked temperature, humidity and dew point inside Orion’s storage lockers. Spacecraft engineers rarely get that kind of cabin record handed to the public.

Reading guides and the road to Artemis III

Raw files of this size need instructions, and NASA published three companion documents: a preliminary lunar science report, a lunar science operations report dated October 2, 2026, and a Lunar Science Data User Guide. The guide tells users how to cite individual crew images and where to find tools that read, display and validate the products. The mission bundle page lists the supporting documents, and the archive’s anonymous FTP service is one route for pulling large batches.

NASA says the information is already feeding its planning for Artemis III and later missions, and that it complements decades of Apollo and robotic data as the agency prepares for long-term work on the lunar surface. The audio is the unusual piece for scientists: spoken descriptions of color, texture and brightness, tied to timestamps and images, that no orbiting robot could have supplied. A geologist reading the transcripts can compare what the crew said about a crater rim with what the camera recorded at the same minute, then check both against the annotated screenshots, all inside one archive that carries stable DOIs for citation.

What is still missing is concrete. The SPICE bundle, which lets analysts reconstruct exactly where Orion was and how its cameras were pointed for each frame, has no posted date beyond the PDS page’s promise of the near future, and until it lands the geometry behind the 11,000-plus images has to be inferred from the documentation.
