NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a suite of rings on the martian northern plains. Each ring marks the location of a filled and buried (or, in some cases, mostly-filled and nearly-buried) impact crater. The dark spots on some of the rings are boulders—or clusters of smaller rocks—associated with the buried craters.
Location near: 68.7°N, 288.6°W
Image width: ~3 km (~1.9 mi)
Illumination from: lower left
Season: Northern Summer

Tips for Media Use

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.
