The Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey spacecraft has completed an unprecedented full decade of observing Mars from orbit.
THEMIS captured this image on Feb. 19, 2012, 10 years to the day after the camera recorded its first view of Mars. This image covers an area 11 by 32 miles (19 by 52 kilometers) in the Nepenthes Mensae region north of the Martian equator. The view depicts a knobby landscape where the southern highlands are breaking up as the terrain descends into the northern lowlands.
Odyssey, launched in 2001, has worked at Mars longer than any mission in history.
NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Mars Odyssey mission for NASA's Science Mission Directorate, Washington. THEMIS was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Philip Christensen at ASU. Lockheed Martin Space Systems in Denver built the spacecraft. JPL and Lockheed Martin collaborate on operating it. JPL is a division of the California Institute of Technology in Pasadena.
