Lunar Trailblazer's HVM³ Imaging Spectrometer Before Spacecraft Integration

The High-resolution Volatiles and Minerals Moon Mapper (HVM³) sits in a clean room at NASA's Jet Propulsion Laboratory in Southern California in early December 2022. The JPL-built instrument was later shipped to Lockheed Martin Space in Littleton, Colorado, to be integrated with NASA's Lunar Trailblazer spacecraft. HVM³ is an imaging spectrometer that will detect and map water on the Moon's surface to determine its abundance, location, form, and how it changes over time.
