The ejecta blanket created around impact craters is often much more resistant to erosion than surrounding surface materials. As seen by NASA's Mars Odyssey, the ejecta material creates isolated highs as surrounding surface is eroded near Meridiani Planum.

The ejecta blanket created around impact craters is often much more resistant to erosion than the surrounding surface materials. In this case of a crater near Meridiani Planum the ejecta material is creating isolated highs as the surrounding surface is eroded.

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.
