NASA/JPL/Malin Space Science Systems

One goal of the
Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) extended
mission is to examine middle- and polar-latitude gullies at
the highest resolutions available to MOC. This image, at 1.5
meters (5 feet) per pixel, shows several gullies carved into
the material covering the wall of an old meteor impact crater
near 46.7°S, 162.3°W. Large boulders that have
come down the slopes are present among the gullies and their aprons.
The image 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.
