MGS MOC Release No. MOC2-247, 26 July 2000
At this time, frost left-over from the recent winter is slowly subliming away to expose underlying northern plains and sand dune surfaces. The picture above shows a frost-covered portion of the vast dune fields that surround the north polar cap as they appeared on July 22, 2000. In summer, the dunes are dark, but in winter and early spring they are covered with bright frost. Small dark spots and streaks indicate areas where the frost has begun to dissappear. This Mars Global Surveyor Mars Orbiter Camera image covers an area 2.3 km (1.4 mi) wide by 7.7 km (4.8 mi) long near 78°N, 107°W 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, 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.
