NASA/JPL/Malin Space Science Systems

This red wide angle Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows Ascraeus Mons, the northernmost of the three Tharsis Montes shield volcanoes. Ascraeus Mons is about 460 km (~286 mi) across and its summit is at an elevation of about 18 km (11 mi) above the martian datum--the elevation designated as 0 km. The center of the summit caldera is near 11°N, 104°W. Sunlight illuminates the scene from the left/upper 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.
