NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a trough in the Stygis Catena region east of the martian volcano, Elysium Mons. The trough probably formed by collapse. Large, dark boulders can be seen on the trough floor in this volcanic region. The image is located near 24.4°N, 210.4°W. The image covers an area about 3 km (1.9 mi) wide and 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.
