is a spectrograph operating at a wavelength of 1.8-3.2 um. NIRS3 was used for analysis of surface mineral composition.

The Thermal-Infrared Imager (TIR) is a thermal infrared camera working at 8-12 um, using a two-dimensional microbolometer array. Its spatial resolution is 20 m at 20 km distance or 5 cm at 50 m distance (70 ft at 12 mi, or 2 in at 160 ft). It was used to determine surface
