This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image, acquired in December 2003, shows light-toned sedimentary
rocks (bottom half of image) and dark-toned sand dunes and
ripples (top half of image). The light-toned, wind-eroded
rocks are formed of ancient sediments; while the dark-toned,
wind-blown dunes and ripples are modern sediments. This
picture is located in Ophir Chasma
near 4.4°S, 71.1°W.
The image covers an area 3 km (1.9 mi) wide;
sunlight illuminates the scene from the lower 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.
