**WASHINGTON, USA, April 12, 2026 —** NASA published 800 gigabytes of Artemis II lunar science data to the Planetary Data System on 12 April 2026.[^1]

Alongside the raw dataset, NASA released three formal supporting documents: the Artemis II Preliminary Lunar Science Report, the Artemis II Lunar Science Operations Report, and the Artemis II Lunar Science Data User Guide.[^2]

Included within the dataset are 8.5 hours of audio recordings capturing the crew's live scientific observations of the lunar surface during the mission.[^3]

An initial preliminary summary report titled 'Artemis II: Sights & Sounds of Science' was first issued on 1 April 2026, following completion of the mission.[^4]

During the flight, the crew witnessed a 54 minute total solar eclipse, providing unobstructed observations of the Sun's corona and space weather.[^5]

NASA scientists plan to compare the crew's handheld camera observations against data collected by the Lunar Reconnaissance Orbiter, as part of work to understand lunar geological evolution.[^6]

**Impact Insight.** NASA's Planetary Data System is the public archive where mission data are kept so that any scientist can use them for decades. The link to planetary defense is indirect: the same archive holds NASA's observations of asteroids and comets, and open data lets researchers worldwide check and build on them.
