NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows alternating light and dark wind streaks superimposed over a rugged lava flow surface on the west flank of the volcano, Ascraeus Mons. A chain of pits in the upper half of the image mark the location of a collapsed lava tube. The image is located near 11.6°N, 105.5°W, and covers an area about 3 km (1.9 mi) across. The scene is illuminated by sunlight 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.
