CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Tethys Before Titan

Terrain on Saturn's moon Tethys, defined with craters, is shown in front of the hazy atmosphere of the larger moon Titan in this Cassini image.

Titan is 5,150 kilometers, or 3,200 miles, across. Tethys is 1,062 kilometers, or 660 miles, across. This view looks toward the Saturn-facing sides of Titan and Tethys.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 17, 2009. The view was obtained at a distance of approximately 1.9 million kilometers (1.2 million miles) from Tethys and 2.9 million kilometers (1.8 million miles) from Titan. Image scale is 12 kilometers (7 miles) per pixel on Tethys and 17 kilometers (11 miles) per pixel on Titan.

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.
