Lunar Trailblazer carries two instruments to achieve its science objectives: the High-resolution Volatiles and Minerals Moon Mapper (HVM3) from JPL, and the Lunar Thermal Mapper (LTM) from the University of Oxford. When used in conjunction, these two instruments provide the ability to simultaneously identify the various forms of water on the moon, mineralogy, and temperature.

The High-resolution Volatiles and Minerals Moon Mapper (HVM3) instrument is a pushbroom shortwave infrared (SWIR) imaging spectrometer. With a spatial resolution of 70 m/pixel over a 20 km swath width, and a spectral resolution of 10 nm over a spectral range of 0.6 to 3.6 μm, HVM3 is optimized for the detection of volatiles to map OH, bound H2O, and water ice.

The Lunar Thermal Mapper (LTM) is a pushbroom multichannel imaging thermal radiometer. With a spatial resolution of 25 m/pixel over an 11 km swath width, 4 broad bands between 6 and 100 μm, and 11 bands between 7 and 10 μm, LTM simultaneously maps temperature (110-400 K), physical properties, and composition of water-bearing areas in HVM3 pixels.
