Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-585, 25 December 2003

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows gullies carved into a slope in southern Galle Crater,
east of Argyre Planitia. These may have been carved by a liquid
such as water. The slopes are part of the inner ring of rocky
mountains uplifted by the asteroid or comet impact that formed
Galle Crater. The crater is extremely ancient; the gullies are
much more recent landforms. The picture is located
near 51.8°S, 31.2°W, and covers an area 3 km (1.9 mi) wide.
Sunlight illuminates the scene from the upper 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.
