|This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark sand dunes, with a thin coating of autumn frost, in the Ogygis Regio west of Argyre basin. The steepest slopes on the dunes, their slip faces, point toward the north-northeast (upper right), indicating that the dominant winds in the region blow from the south-southwest (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.
