This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle color composite image, obtained in December 2003, shows the middle of the three Tharsis Montes, Pavonis Mons. This is a broad shield volcano--similar to the volcanoes of Hawaii--located on the martian equator at 113°W. The volcano summit is near 14 km (~8.7 mi) above the martian datum (0 elevation); the central caldera (crater near center of image) is about 45 km (~28 mi.) across and about 4.5 km (~2.8 mi.) deep. Sunlight illuminates the scene from the lower left.
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.
