MGS MOC Release No. MOC2-791, 18 July 2004

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows troughs and a pit, possibly formed by collapse, on the volcanic plains south of the large volcano, Ascraeus Mons. Wind-eroded debris mantles the scene and partly fills the depressions. The image is located near 4.5°N, 105.5°W, and covers an area about 3 km (1.9 mi) wide. 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.
