They are in the Science Evaluation Room (SER) a back room that supports lunar science and planetary observations for the Artemis science officer in the mission’s main flight control room. Built specifically for Artemis missions with these science priorities in mind, the SER is equipped to support rapid data interpretation, collaborative analysis, real-time decision making, and seamless coordination between the science and operations teams.

The Artemis II lunar science team gathers for a kickoff meeting before working on the lunar targeting plan for the crew's lunar flyby. The Lunar Targeting Plan is the Artemis II crew's Moon observing assignment, and is fine-tuned to the exact lighting conditions on the Moon’s surface when the Artemis II crew flies by. Like a spacewalk plan, it provides strong, detailed guidance, plus flexibility for the crew to make decisions based on what they’re seeing and experiencing in real time. Targets are prioritized based on both their science value and their visibility at the time of observation. Credits: NASA/Luna Posadas Nava

Artemis II lunar science team members, from left, Amber Turner, Jacob Richardson, Jose Hurtado, discuss the team's progress on the lunar targeting plan for the astronauts' six-hour flyby of the Moon, scheduled for April 6. As they pass the Moon, the crew will apply geology skills learned in the classroom and in Moon-like environments on Earth to photograph and describe features including impact craters, ancient lava flows, and surface cracks and ridges formed as the Moon slowly changed over time. They will note differences in color, brightness, and texture, which provide clues that help scientists understand what the surface is made of and how it formed. Credits: NASA/Bill Stafford
