CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Beyond Southern Rhea
[For trouble viewing the images/movies on this page, go here]
Cassini looks past the cratered south polar area of Saturn's moon Rhea to spy the moon Dione and the planet's rings in the distance.

Dione's "wispy" terrain can be seen on the trailing hemisphere of that moon. See PIA10560 to learn more.

This view looks toward the south polar area of the anti-Saturn side of Rhea (1528 kilometers, 949 miles across) and the Saturn-facing side of Dione (1123 kilometers, 698 miles across). North on the moons is up.

This view looks toward the northern, sunlit side of the rings from just above the ringplane. The rings, closer to Cassini than Dione is, obscure the view of the south of Dione.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 11, 2011. The view was acquired at a distance of approximately 61,000 kilometers (38,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 15 degrees. The view was acquired at a distance of approximately 924,000 kilometers (574,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 15 degrees. Image scale is 358 meters (1,175 feet) per pixel on Rhea and 6 kilometers (4 miles) per pixel on Dione.

The Cassini Solstice 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.

IapetusMonolith: Ring is F ring. Not sure what blob is but maybe a blob!

Stunning! Which ring forms the dark line across Dione? And what is that slightly thicker 'blob' in the foremost arc of that same ring, just to the right of Dione's western limb?

Magic.

Fabulous. Fabulous!
Cassini makes us dream again and again after all these years.

A very special view.
