NASA/JPL/Malin Space Science Systems

This August 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a suite of collapse pits on the northeast flank of the volcano, Ascraeus Mons. These pits are aligned along the trend of faults that are not well exposed at the surface; the faults are concentric to the volcano summit. The image is located near 13.0°N, 103.2°W. This picture covers an area 3 km (1.9 mi) across and is illuminated by sunlight from the lower left.

Tips for Media Use

Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, California. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, California and Denver, Colorado.
