NASA Mars Picture of the Day: Lycus Sulci Slope Streaks 03-21-2004

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows dark slope streaks on ridges
in the Lycus Sulci region, north of the Olympus Mons volcano.
Slope streaks form in the dry, dust-mantled regions of Mars.
The darker streaks formed more recently than lighter ones,
perhaps within the past Mars year or two. These streaks are located
near 24.1°N, 146.1°W.
This picture covers an area about 3 km (1.9 mi) across.
Sunlight illuminates the scene 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, 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.
