THEMIS for scientists and researchers
The Thermal Emission Imaging System (THEMIS) is an instrument on board NASA's Mars Odyssey orbiter. It combines a 5-band visual imaging system with a 10-band infrared imaging system.
THEMIS began scientific mapping February 18, 2002. Below are links to all released data, instrument descriptions, useful software, and THEMIS-based publications in refereed journals.
