This image from NASA's Mars Odyssey shows the northeast flank of the 27 km-high volcano Ascraeus Mons on Mars, a set of collapse pits and troughs.

Released 2 May 2003

On the northeast flank of the 27 km-high volcano Ascraeus Mons, a set of collapse pits and troughs vaguely resemble the symbols of an Asian language. This image shows a range of landforms that are produced by flowing lava and its aftermath: surface flow lobes and channels, source pits, lava tubes, and collapse depressions.

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.
