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.

This dramatic close-up of Tethys shows the large crater Penelope lying near center, overprinted by many smaller, younger impact sites.

Three smaller impact features of roughly similar size make a line left of Penelope that runs north-south: (from bottom) Ajax, Polyphemus and Phemius.

Features on Tethys are named for characters and places from "The Iliad" and "The Odyssey." The largest impact structure on Tethys is named Odysseus. (See PIA07693 for a stunning close-up of Odysseus.)

The view is toward the Saturn-facing hemisphere on Tethys (1,071 kilometers, or 665 miles across). North is up.

The image was taken in polarized ultraviolet light with the Cassini spacecraft narrow-angle camera on Feb. 25, 2006 at a distance of approximately 165,000 kilometers (103,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 23 degrees. Image scale is 984 meters (3,227 feet) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
