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:

A large circular feature about 200 kilometers (120 miles) across with a dark spot in its center is visible in this photograph of Saturn's satellite Iapetus taken Nov. 12, 1980 from a distance of 3.2 million kilometers (1.9 million miles). The satellite's leading hemisphere is to the left, and the trailing hemisphere, which is about four to five times brighter, is to the right. The large circular feature is most probably a large impact structure outlined by dark material, possibly thrown out by the impact. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
