NASA’s Artemis II crew had many technical and operational responsibilities during their historic mission to the Moon, but they also served an important role as scientific ambassadors to Earth’s nearest neighbor.

On their 10-day journey, the crew flew by the far side of the Moon, analyzing and photographing geologic features such as impact craters and ancient lava flows. Their observations will help pave the way for science activities on future Artemis missions to the Moon’s surface and contribute to lunar and planetary science. The crew relied on the extensive geology training they received on Earth to describe nuances in shapes, textures, and colors — the type of information that reveals the geologic history of an area.

Cindy Evans, Artemis exploration scientist and geology training lead, was one of the crew’s instructors. Based at NASA’s Johnson Space Center in Houston in the Astromaterials Research and Exploration Science (ARES) Division, Evans is part of the Artemis Internal Science Team and spearheads geology training for crew members, mission managers, engineers, and flight controllers. That effort centers around a core curriculum of geology, lunar, and planetary classroom science as well as a progression of geology-focused field classes.
