The '''Thermal Emission Imaging System''' ('''THEMIS''') is a camera on board the [[2001 Mars Odyssey]] orbiter.  It images [[Mars]] in the visible and [[infrared]] parts of the [[electromagnetic spectrum]] in order to determine the thermal properties of the surface and to refine the distribution of [[minerals]] on the surface of Mars as determined by the [[Thermal Emission Spectrometer]] (TES).  Additionally, it helps scientists to understand how the [[mineralogy]] of Mars relates to its landforms, and it can be used to search for thermal hotspots in the Martian subsurface.

THEMIS is managed from the [[Mars Space Flight Facility]] at [[Arizona State University]] and was built by the Santa Barbara Remote Sensing division of [[Raytheon|Raytheon Technologies Corporation]], an American [[multinational corporation|multinational]] [[list of conglomerates|conglomerate]] headquartered in [[Waltham, Massachusetts]].  The instrument is named after [[Themis]], the goddess of justice in ancient [[Greek mythology]].
