CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Steep Scarps

This view of Tethys' surface, taken during Cassini's close approach to the moon on September 24, 2005, reveals an icy land of steep cliffs. The view is of the southernmost extent of Ithaca Chasma, in a region not seen by NASA's Voyager spacecraft.

The ridges around Ithaca Chasma have been thoroughly hammered by impacts. This appearance suggests that Ithaca Chasma as a whole is very old.

Brighter material in floors of many craters on Tethys is the opposite situation from that on Saturn's oddly tumbling moon Hyperion, where dark material is concentrated in the bottoms of many craters.

This view is centered on terrain at approximately 2.5 degrees south latitude and 352 degrees west longitude on Tethys. North on Tethys is toward the right in this view.

This clear filter view was obtained using the narrow angle camera from a distance of approximately 32,300 kilometers (20,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 20 degrees. Image scale is 190 meters (620 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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
