Context image

This false color image shows part of the inner rim (bottom of image), central peak ring (top of image) and floor of Sagan Crater. This 90 km (56 miles) crater was named for Carl Sagan. Peak rings are created during impact by uplift of the center and slumping of the walls of large craters (~100 km). The small blue dots are sand dunes. Basaltic sands are typically blue in this false color combination.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.
