Lunar Trailblazer

Lunar Trailblazer is a planned small lunar orbiter, part of NASA's SIMPLEx program, that will detect and map water on the lunar surface to determine how its form, abundance, and location relate to geology. Its mission is to aid in the understanding of lunar water and the Moon's water cycle. Lunar Trailblazer is currently slated to launch in 2023 as a secondary payload on the IM-2 mission, with the satellite scheduled to be completed in early 2023. The Principal Investigator of the mission is Bethany Ehlmann, a professor at Caltech.
