This image taken by NASA's 2001 Mars Odyssey shows Hebes Chasma, the northernmost canyon of Mars' vast Valles Marineris system.

Released 2 June 2003

Hebes Chasma is the northernmost canyon of the vast Valles Marineris system. It contains a 7-km thick pile of sediments known as an interior layered deposit (ILD), which is common to many of the VM canyons. This ILD shows fine layers, deep spur-and-gulley erosion, and an unusual texture on the plateau surface that may be due to dunes.

Image information: VIS instrument. Latitude -1.1, Longitude 283 East (77 West). 19 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.
