CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Spokes Before Night
[For trouble viewing the images/movies on this page, go here]
Bright spokes can be seen on Saturn's B ring just in front of the shadow cast on the rings on the night side of the planet in this Cassini image.

The spokes are on the left of the image. See PIA12605 to learn more. Saturn's moon Tethys (1062 kilometers, 660 miles across) can be seen in the upper right of the image. The moon Enceladus (504 kilometers, 313 miles across) is visible in the lower right. Both moons are overexposed.

This view looks toward the northern, sunlit side of the rings from about 8 degrees above the ringplane.

The image was taken in visible green light with the Cassini spacecraft wide-angle camera on May 30, 2010. The view was obtained at a distance of approximately 1.9 million kilometers (1.2 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 104 degrees. Image scale is 110 kilometers (69 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.
