This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows a rounded knob in the Propontis region of Mars near 43.1°N, 182.3°W. Dark dots on the hilltop and slopes are house-sized (and larger) boulders. The picture covers an area about 3 km (1.9 mi) across. 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.
