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. A second instrument, the Lunar Thermal Mapper infrared multispectral imager, is being developed by the University of Oxford in the U.K. and is scheduled for delivery and integration in early 2023. 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.
