CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Dione and the Dark Side

Cassini looks to the night side of Saturn and its rings for a view that includes Dione.

Dione (1123 kilometers, 698 miles across) is in the top right of the image. Tiny Pandora (81 kilometers, 50 miles across) can also be seen outside the F ring near the center of the image. Dione was overexposed in this image and has been dimmed by a factor of seven.

This view looks toward the sunlit, northern side of the rings from about 12 degrees above the ringplane.

The image was taken with the Cassini spacecraft wide-angle camera on Sept. 22, 2009 using a spectral filter sensitive to wavelengths of near-infrared light centered at 742 nanometers. The view was obtained at a distance of approximately 1.3 million kilometers (808,000 miles) from Saturn. Image scale is 72 kilometers (45 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. 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.
