Mars Global Surveyor
Mars Orbiter Camera

Hill and Depression

MGS MOC Release No. MOC2-917, 21 November 2004

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows exposures of north polar layered material--perhaps composed of a mixture of dust and ice--in the form of a hill and an adjacent depression. The depression is in the lower half of the image and forms an oval shape at its lowest elevations. The hill is immediately above the depression (above the center of the image) and forms a similar pattern of arcuate bands. This scene is located near 85.7°N, 21.0°W. The image covers an area approximately 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.

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.
