What Happened
- Despite advances in camera and sensor technology since the Apollo era, NASA built the Artemis II science observation plan around the primary use of astronaut eyesight during the lunar flyby.
- The human eye outperforms current space-rated cameras in three key areas: colour discrimination, photometric sensitivity (how light interacts with surface textures), and contextual interpretation — the ability to understand surface features in relation to surrounding terrain in real time.
- Artemis II crew members were trained as field scientists and assigned to photograph and verbally describe specific lunar surface features during the 6 April 2026 flyby's 6-hour science window.
- Scientists on the ground — including newly designated Artemis Science Officers in Mission Control — relay observation priorities to the crew in near-real time.
- The approach mirrors how Apollo geologist-astronaut Harrison Schmitt (Apollo 17) provided invaluable real-time geological descriptions that instruments alone could not replicate.
- The crew observed far-side features including the Orientale basin, Pierazzo crater, and Ohm crater — all seen by human eyes for the first time.

Key Facts & Data
- Human eye advantages in space geology: Colour discrimination, photometric observation, contextual awareness, real-time interpretation.
- Artemis Science Officers: Newly embedded in Mission Control for the Artemis programme — a structural change from Apollo.
- Apollo 17 geologist: Harrison Schmitt — the only professional geologist to walk on the Moon.
- Artemis II flyby: 6 April 2026; 6-hour science window; ~20% of Moon's far side visible.
- Far-side features observed: Orientale basin (~930 km diameter), Pierazzo crater, Ohm crater.
- Crew: Reid Wiseman (CDR), Victor Glover, Christina Koch (NASA); Jeremy Hansen (CSA).
- Mission launch: 1 April 2026; 10-day total duration.
- Last human to visually observe lunar surface: Apollo 17, December 1972 — over 53 years before Artemis II.
