Mars Global Surveyor Mars Orbiter Camera

MGS MOC Release No. MOC2-568, 8 December 2003




NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows troughs created by movement along geologic
faults in the upper crust of Mars in the Tempe Terra region.
Large ripple-like dunes have formed in sediment trapped
on the floors of the troughs. In most cases, the ripples
are oriented with their crests perpendicular to the troughs,
indicating that local winds within each trough are responsible
for their patterns. This area is
located near 33.1°N, 70.2°W.
The image covers an area approximately 3 km
(1.9 mi) wide and is illuminated 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.
