File:PIA21184 - Crater on Crater.jpg

English: This VIS images shows part of two unnamed craters in Noachis Terra. The younger of the two craters is at the bottom of the image with one side visible in the image. The older and much larger crater has just part of the rim and floor visible towards the top of the image. The overlapping of one crater on top of another allows for relative dating to be done. We don't know the exact ages of each crater, but we can define which came first.

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.
