CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Satellite Trio

This excellent grouping of three moons near the rings provides a sampling of the diversity of worlds that exists in Saturn's realm.

A 330-kilometer (205 mile) wide impact basin can be seen near bottom right on Dione (1,123 kilometers, 698 miles across, at left). Ithaca Chasma and the region imaged during Cassini's September 24, 2005 flyby can be seen on Tethys (1,062 kilometers, 660 miles across, middle). Little Pandora (81 kilometers, 50 miles across) makes a good showing here as well, displaying a hint of surface detail.

Tethys is on the far side of the rings in this view; Dione and Pandora are much nearer to Cassini.

The image was taken in visible blue light with the narrow angle camera on September 22, 2005, from a distance of approximately 1.2 million kilometers (800,000 miles) from Saturn. The image scale is about 5 kilometers (3 miles) per pixel on Dione and Pandora and 9 kilometers (6 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.
