Context image

This VIS image shows the part of the crater rim and ejecta surrounding Lonar Crater in the northern plains of Vastitas Borealis. There is a fine scale, radial grooved outer layer of ejecta covered by lobate ejecta nearer the crater rim. The ends of the lobes are taller than the material just inside the end of the lobe. Often called rampart ejecta, this morphology can be caused by impact into a surface that includes volatiles such as sub-surface water or ice.

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.
