The surface of Mars has been studied using the Thermal Emission Imaging System (THEMIS) instrument during the initial phases of the 2001 Mars Odyssey mapping mission. The THEMIS investigation has studied surface mineralogy, physical properties, and atmospheric temperature using multi-spectral thermal-infrared images in nine spectral bands from 6.5 to 15.5 æm. The entire planet will eventually be mapped at 100 m resolution within the available data volume. THEMIS also acquires 18-m resolution visible images in up to 5 spectral bands using a replica of the MS'98 Orbiter (MARCI) and Lander (MARDI) cameras. THEMIS is designed as the follow-on to the Mars Global Surveyor Thermal Emission Spectrometer (TES), which has produced a hyperspectral (143-band) mineral map of the entire planet. THEMIS covers the same wavelength region as the TES, allowing direct comparison of the two data sets. In addition to mineral mapping studies, THEMIS will map the thermophysical properties of the entire planet, and search for thermal anomalies associated with active sub-surface hydrothermal systems. The THEMIS infrared and visible multi-spectral images have revealed a wealth of detail on the compositional and physical diversity of the martian surface that will be discussed.
