What Happened
- Ahead of the 6 April 2026 lunar flyby, the Artemis II crew completed preparatory activities including reviewing lunar geology training and organising Orion's windows for optimal observation.
- The crew had received months of geology training — classroom sessions and field expeditions to Iceland and Canada — to identify and describe lunar surface features including ancient lava flows, impact craters, and compositional variations.
- During the flyby's 6-hour science observation window, crew members were assigned specific features to photograph and describe, functioning as field geologists.
- NASA's Artemis missions mark a structural shift from Apollo: dedicated Science Officers are now embedded within Mission Control, whereas Apollo had no science representative in the Mission Control front room.
- The crew's human eyesight provides scientific advantages over cameras in detecting subtle colour shifts, surface texture variations, and real-time contextual observations.

Key Facts & Data
- Lunar flyby window: 6 April 2026, 2:45–9:40 PM EDT; closest approach at ~7:02 PM EDT.
- Closest approach distance: 4,066 miles from the Moon's surface.
- Science observation window: ~6 hours during flyby.
- Far-side coverage: ~20% of the sunlit far side visible from Orion.
- Field geology training sites: Iceland, Canada.
- Apollo comparison: No dedicated science officer in Apollo Mission Control front room; Artemis has certified Artemis Science Officers.
- Human eye advantage: Superior colour discrimination, dynamic range, and contextual awareness compared to cameras.
- Features observed: Orientale basin, Pierazzo crater, Ohm crater — none previously seen by unaided human eyes.
