Artemis II lunar science team member, Ryan Ewing -- jsc2026e020766

Artemis II lunar science team member, Ryan Ewing, reacts to the astronauts' verbal observations of the Moon during their flyby on April 6, 2026. Along with other lunar science team members, Ewing helped train the crew in geology both in the classroom and in the field. The science team also built the lunar targeting plan that, like an International Space Station spacewalk plan, provides strong, detailed observation guidance, plus flexibility for the crew to make decisions based on what they’re seeing and experiencing in real time. The science team had many moments of celebration during the lunar flyby as the astronauts took images of the Moon and provided verbal descriptions of what they were seeing. This type of information reveals the geologic history of an area and will be critical to collect when future Artemis astronauts explore the Moon's surface. Credits: NASA/Luna Posadas Nava
