An engineer works on the High-resolution Volatiles and Minerals Moon Mapper (HVM³) for NASA's Lunar Trailblazer spacecraft in a clean room at Lockheed Martin Space in Littleton, Colorado, shortly after the instrument delivered in December 2022. HVM³ is an imaging spectrometer that was developed at NASA's Jet Propulsion Laboratory in Southern California. It was shipped from JPL to Lockheed Martin Space, where it was integrated with the spacecraft.

HVM³ is one of two instruments that will be used by the mission to detect and map water on the Moon's surface to determine its abundance, location, form, and how it changes over time. Lunar Trailblazer was selected under NASA's Small Innovative Missions for Planetary Exploration (SIMPLEx) program in 2019.

The Lunar Trailblazer mission is managed by JPL and its science investigation is led by Caltech in Pasadena, California. Managed for NASA by Caltech, JPL also provides system engineering, mission assurance, the HVM³ instrument, as well as navigation. Lockheed Martin Space provides the spacecraft and integrates the flight system, under contract with Caltech.

SIMPLEx mission investigations are managed by the Planetary Missions Program Office at NASA's Marshall Space Flight Center in Huntsville, Alabama, as part of the Discovery Program at NASA Headquarters in Washington. The program conducts space science investigations in the Planetary Science Division of NASA's Science Mission Directorate at NASA Headquarters.
