CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Rings and Quarter Tethys
[For trouble viewing the images/movies on this page, go here]
A quarter of the moon Tethys is illuminated beyond a swath of Saturn's rings.

The moon is farther from Cassini than the rings are here. Lit terrain seen here is mostly on the leading hemisphere of Tethys (1062 kilometers, 660 miles across). This view looks toward the northern, sunlit side of the rings from just above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 15, 2010. The view was acquired at a distance of approximately 2.8 million kilometers (1.7 million miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 95 degrees. Image scale is 17 kilometers (11 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.
