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.

Two moons on opposite sides of the rings slide past each other in this stately portrait of Saturn.

Dione (1,126 kilometers, or 700 miles across), on the far side of Saturn, appears above the rings. Tethys (1,071 kilometers, or 665 miles across) poses directly in front of the ringplane.

This view looks toward the unilluminated side of the rings from less than a degree above the ringplane. The silhouette of the rings overlay the subtle texture of Saturn's atmosphere.

The image was taken in visible green light with the Cassini spacecraft wide-angle camera on July 29, 2007. The view was obtained at a distance of approximately 3.2 million kilometers (2 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 32 degrees. Image scale is 188 kilometers (117 miles) per pixel.
