This image released on Nov 26, 2004 from NASA's 2001 Mars Odyssey shows a group of channels on Mars that originate from the Elysium volcanic field. Called Granicus Vallis, these channels are related to the volcanic activity of Elysium Mons.

This day time IR image shows a group of channels that originate from the Elysium volcanic field. Called Granicus Vallis, these channels are related to the volcanic activity of Elysium Mons and may be lava channels rather than fluvial. Note the lava flows at the top of the image.

Image information: IR instrument. Latitude 27.5, Longitude 132.9 East (227.1 West). 100 meter/pixel resolution.

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.

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.
