NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a deep channel formed on the northern flank of the large volcano, Ascraeus Mons. Layers of volcanic rock are exposed in the channel walls, and the dark dots on the valley floor are boulders derived from erosion of these materials. The picture occurs near 14.5°N, 102.8°W, and is illuminated from the lower left. The picture covers an area about 3 km (1.9 mi) across.

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.
