NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows lava flows on the middle west flank of the large martian volcano, Ascraeus Mons. The flows ran downslope from the lower right (southeast) toward upper left (northwest). These flows are located near 11.9°N, 105.5°W. This December 2003 image covers an area about 3 km (1.9 mi) across; sunlight illuminates the scene 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.
