This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a gully formed in the wall of a north middle-latitude crater. Similar gullies are common at the middle and polar latitudes of Mars, and might have formed by the action of liquid water. Others have argued for carbon dioxide or dry mass movement for the genesis of such landforms. This particular image was acquired during northern autumn, when the sky over the terrain of the martian northern mid-latitudes is typically hazy.

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.
