NASA Mars Picture of the Day: Pit Chain on Olympus
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-703, 21 April 2004
NASA/JPL/Malin Space Science Systems
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows a chain of collapse pits on the lower northeast
flank of the large martian volcano, Olympus Mons. For these
to have formed, something in the subsurface must have been
removed or changed volume, such as cooling lava within a
subsurface lava tube or extension of the crust by faulting.
These pits are located
near 20.6°N, 129.4°W.
The 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.
