PDS Information
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.

Original Caption Released with Image:

This 10.5 by 11 km sub-area in northern Chile was acquired by ASTER on April 7, 2000. Dramatically displayed is a geological angular unconformity: a contact between layers of rock at different angles. On the right side of the image, Cretaceous sediments were tilted upward to an angle of about 50 degrees, then eroded. On this surface volcanic pyroclastic deposits were deposited as a flat sheet. The section of rocks has been eroding from the east, exposing the tilted and flat rock layers. The image is located at 24.8 degrees south latitude and 69.1 degrees west longitude.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.
