Artemis II mission is offering NASA clues for moon base design.

Artemis II crew observations from their recent lunar flyby are providing information that NASA says could shape plans for a moon base. Astronauts reported seeing flashes from impacts during a solar eclipse, which officials say may update models of how often the lunar surface is struck.

Less than two weeks after the Artemis II mission, officials said crew observations from the lunar flyby are already informing thinking about how to build a base on the moon. NASA Administrator Jared Isaacman described the findings during a live conversation with NBC's Lester Holt and former astronaut Sunita Williams. The Artemis II flight launched April 1 and completed a close approach to the moon on April 6, when the crew spent several hours taking photographs and making observations. The astronauts were reported as the first to see the entire far side of the moon with their own eyes. Key observations: - The Artemis II crew included Reid Wiseman, Christina Koch, Victor Glover and Canadian astronaut Jeremy Hansen, and the mission lasted about 10 days. - During the closest approach on April 6, the crew spent roughly seven hours photographing and observing the lunar surface. - Astronauts reported seeing multiple flashes of light on the moon during a solar eclipse, which were described as rocky objects striking the surface. - Mission Control at the Johnson Space Center reacted with excitement when the flashes were reported, and officials said the sightings allow scientists to consider updating impact-rate models. - Jared Isaacman said those updated models could inform design choices for future lunar infrastructure, including considerations for shielding or roof design. Summary: Officials said the Artemis II observations are shaping NASA's plans for infrastructure to support longer stays on the lunar surface. The reported impact flashes could lead to updated models of how often the moon is struck and influence design considerations. Undetermined at this time.
