Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

PIA07215: West of Meridiani
NASA's Mars Global Surveyor shows an eroded landscape occurring west of Sinus Meridiani on Mars. The bedrock at this location is buried beneath a mantle of dust, sand, and granules. Two circular mesas were once meteor impact craters.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an eroded landscape occurring west of Sinus Meridiani, the region in which the Mars Exploration Rover, Opportunity, landed nearly a year ago. The bedrock at this location is buried beneath a mantle of dust, sand, and granules, but remnants of younger layers of bedrock now stand high in the form of buttes in the lower right quarter of the image. The two circular mesas were once meteor impact craters. They were filled, buried, and fossilized within the rock, then later exhumed. This scene is located near 1.5°N, 6.2°W. The picture covers an area about 3 km (1.9 mi) across, and is illuminated by sunlight from the lower left.
