With the icy rings between them, Dione and Tethys each show off the prominent features for which they are known. Dione (1,123 kilometers, 698 miles across), beyond the rings, displays wispy fractures that adorn its trailing side. Tethys (1,062 kilometers, 660 miles across), on the side of the rings closest to Cassini, shows its large impact basin Odysseus.

At right, the night side of Saturn can be seen occulting the far side of the rings. The view shows the Saturn-facing side of Dione and the anti-Saturn side of Tethys.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 8, 2005, at a distance of approximately 3.5 million kilometers (2.2 million miles) from Dione and 2.8 million kilometers (1.8 million miles) from Tethys. The image scale is 21 kilometers (13 miles) per pixel on Dione and 17 kilometers (11 miles) per pixel on Tethys.

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.
