PIA04402: Etched Terrain in Terra Meridiani


Etched Terrain in Terra Meridiani

Caption:

Eroded, or "etched" terrain dominates the field of view of this THEMIS visible image acquired over eastern Terra Meridiani. At the bottom of many craters and in other areas, dunes are present. On the left hand side of the image, a darker layer embays the etched terrain. Several knobs from the etched terrain can still be seen, though, indicating that this layer is rather thin.

Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.

Image information: VIS instrument. Latitude 1.6, Longitude 5.5 East (354.5 West). 19 meter/pixel resolution.

Background Info:

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, 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.
