NASA Mars Picture of the Day: Martian Gullies 06-14-2004
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-757, 14 June 2004
NASA/JPL/Malin Space Science Systems
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows a gullied crater wall at 1.5 meters (5 feet)
per pixel resolution. The gullies in this case have formed
in a thick, smooth-surfaced mantle that covers the crater
wall. Formation of these gullies might have involved a
fluid such as water, or perhaps could have formed by
avalanching of dry debris. The Mars science community
is still discussing, debating, and making new observations
of martian gullies to better understand their origin and
implications. These gullies are located
near 33.8°S, 201.6°W.
The image covers an area about 3 km (1.9 mi) across.
Sunlight illuminates the scene from the upper 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.
