This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows yardangs, formed by wind erosion, and
large ripples formed in wind by deposition of sediment.
The sharp yardang ridges trend from northwest toward southeast
(upper left to lower right), while the ripple crests
are nearly perpendicular to this trend.

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,
