Children of Saturn
[For trouble viewing the images/movies on this page, go here]
Two moons on opposite sides of the rings slide past each other in this stately portrait of Saturn.

Dione (1,123 kilometers, 698 miles across), on the far side of Saturn, appears above the rings. Tethys (1,062 kilometers, 660 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 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.

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.
