This image from NASA's 2001 Mars Odyssey spacecraft shows a young crater. Dark radial spokes are created by the explosive blast of an impact event. With time, only thick ejecta near the rim of the crater will be visible, and dark spokes will disappear.

This VIS image shows a young crater. The dark radial "spokes" are created by the explosive blast of the impact event. These "spokes" are very thin and are easily covered by dust depositing from the atmosphere. With time, only the thick ejecta near the rim of the crater will be visible, and the dark "spokes" will "disappear."

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.
