This image from NASA's Mars Odyssey shows part of the Sirenum Fossae on Mars. A smaller crater is cut by a large fracture of the fossae system while the ejecta of the crater covers a small fracture just northwest of the crater.

Sirenum Fossae

This VIS image of part of the Sirenum Fossae shows an important interaction. The small crater in the center of the image is cut by a large fracture of the fossae system while the ejecta of the crater covers a small fracture just northwest of the crater. This image indicates that the fracture system was active both before and after the time of the impact and crater creation.

Image information: VIS instrument. Latitude -24.3N, Longitude 220.0E. 17 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.
