Martian Outcrops In Meridiani

July 31, 2012
The sedimentary rock outcrops explored this year by the Mars Exploration Rover, Opportunity, in Meridiani Planum are just the "tip of the iceberg." Northern Sinus Meridiani exhibits vast outcrops of sedimentary rock of widely varied erosional characteristics and physical properties. Investigation of these rocks from orbit using the high resolution capabilities of the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) has been underway for nearly seven years. This MGS MOC image shows an example, complete with small buttes formed of eroded sedimentary rock, in northern Sinus Meridiani. The image is located near 1.2°N, 358.9°W, and covers an area about 3 km (1.9 mi) across. Sunlight illuminates the terrain from the left. MGS MOC Release No. MOC2-804, 31 July 2004
