  Two of Saturn's battered, icy companions hover here, above the ringplane.

To get a sense of the three-dimensional nature of the scene, note that Mimas (396 kilometers, 246 miles across, at left) is on the far side of the rings from Cassini in this view; Dione (1,123 kilometers, 698 miles across) in on the side closest to Cassini.

The view is from just beneath the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 18, 2005, at a distance of approximately 2.2 million kilometers (1.4 million miles) from Dione and 2.7 million kilometers (1.7 million miles) from Mimas. The image scale is 13 kilometers (8 miles) per pixel on Dione and 16 kilometers (10 miles) per pixel on Mimas.

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.
