Leveed Channel in Lava Flow

MGS MOC Release No. MOC2-940, 14 December 2004

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a leveed channel running down the middle of a lava flow in Daedalia Planum, the southern plains of the Tharsis volcanic region. Transport of fluid lava through a channel such as this helps insulate the molten rock, keeping it hot longer, and thus permits the flow to extend to greater distances than it otherwise might. This example is located near 23.6°S, 123.2°W, and covers an area approximately 3 km (1.9 mi) wide. The scene is illuminated by sunlight from the upper 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.
