Artemis 2 astronauts make history. Catch sight of moon's entire ‘Orientale basin’ for the first time
During the Artemis II mission (launched 1 April 2026), the crew became the first humans to observe the entirety of the Orientale basin on the Moon's far side with unaided eyes.
The Orientale basin is a multi-ring impact structure approximately 930 km in diameter, located on the boundary between the near and far sides of the Moon.
From Earth, only a partial edge of Orientale is visible during lunar libration; the full basin structure had never been seen in direct human observation before this mission.
The sighting occurred during the crew's approach to the Moon ahead of the 6 April 2026 lunar flyby.
Crew member descriptions and photographs of the basin were transmitted back to Earth as part of the mission's science observation programme.
