CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Bisected Crescent
[For trouble viewing the images/movies on this page, go here]
The rings halve the planet in this Cassini view of a crescent Saturn.

Saturn's moon Tethys (1062 kilometers, 660 miles across) can be seen as a small dot on the left of the image, below the rings. This view looks toward the northern, sunlit side of the rings from just above the ringplane.

The image was taken with the Cassini spacecraft wide-angle camera on Nov. 28, 2009 using a spectral filter sensitive to wavelengths of near-infrared light centered at 752 nanometers. The view was obtained at a distance of approximately 2.5 million kilometers (1.5 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 103 degrees. Image scale is 143 kilometers (89 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.
