This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned, somewhat layered rock outcrops on the north wall of Columbus Crater, located near 28.7°S, 166.3°W. This material is a remnant of a formerly more extensive light-toned unit that extended across the floor of Columbus. Today, remnants are found all around the walls of the crater, and at least one small remnant has been spotted on the crater floor. The picture covers an area about 3 km (1.9 mi) across. 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.
