Peering into the Moon's permanently shadowed regions, Lunar Trailblazer will detect signatures of water ice in reflected light, and it will pinpoint the locations of micro-cold traps less than a football field in size. The small satellite will collect measurements at multiple times of day over sunlit regions, helping scientists understand if the water signature on the illuminated surface changes as the lunar surface temperature changes by hundreds of degrees over the course of a lunar day. The goal is to produce high-resolution maps to locate water ice in support of NASA's Artemis Program, whi…
