Context image for PIA22612
Context image

This VIS image is located near Zephyria Planum. Winds of two different directions have excavated a poorly cemented surface into linear ridge features called yardangs. Examining the structure of the ridges, it appears that winds first blew from the upper left of the image. Then perhaps after a change in climate, winds blew toward the upper right, carving a new pattern on top of the older one. The ridges are not perpendicular, but intersect at a wider angle.

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.
