Image Caption:

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image
shows several small, dark sand dunes and a small crater (about 1
kilometer in diameter) within a much larger crater (not visible
in this image). The floor of the larger crater is rough and has
been eroded with time. The floor of the smaller crater contains
windblown ripples. The steep faces of the dunes point to the east
(right), indicating that the dominant winds blew from the west
(left). This scene is located near 38.5?S, 347.1?W, and covers
an area approximately 3 km (1.9 mi) wide. Sunlight illuminates
the landscape from the upper left. This southern autumn image
was acquired on 1 July 2006.

Mars Global Surveyor was launched in November 1996 and has been
in Mars orbit since September 1997.   It began its primary
mapping mission on March 8, 1999.  Mars Global Surveyor is the
first mission in a long-term program of Mars exploration known as
the Mars Surveyor Program that is managed by JPL for NASA's Office
of Space Science, Washington, DC.  Malin Space Science Systems (MSSS)
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, CA. 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, CA and Denver, CO.
