CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Expanse of Ice

A scan across Saturn's incredible halo of ice rings yields a study in precision and order.

This natural color mosaic was acquired by the Cassini spacecraft as it soared 39 degrees above the unilluminated side of the rings.

Major named gaps are labeled at top. The main rings themselves, along with the F ring, are labeled at bottom, along with their inner and outer boundaries. An unlabeled version is also presented here.

This mosaic was constructed from narrow-angle camera images taken immediately after the wide-angle camera mosaic PIA08388. Radial features can be seen in the rings that are about ten times smaller than in the wide-angle view. This scan is rotated 180 degrees compared to PIA08388 in order to present the rings with distance from Saturn increasing left to right.

The view combines 45 images -- 15 separate sets of red, green and blue images -- taken over the course of about 2.5 hours, as Cassini scanned across the rings.

The images in this view were obtained on May 9, 2007 at a distance of approximately 1.1 million kilometers (700,000 miles) from Saturn. Image scale in the radial (horizontal) direction is about 6 kilometers (4 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.

"Over the Rings and Far Away" :). It's really fun to compare this magical image with this other: and see how different look the ring system depending of where you're.
