Cassini spies the large Penelope crater on Saturn's moon Tethys.Penelope crater lies near the center of the image. See PIA11495 to learn more about the prominent features on Tethys. This view looks toward the trailing hemisphere of Tethys (1062 kilometers, 660 miles across). North on Tethys is up.
The image was taken with the Cassini spacecraft narrow-angle camera on Oct. 14, 2009 using a spectral filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The view was obtained at a distance of approximately 256,000 kilometers (159,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 1 degree. Image scale is 2 kilometers (5,022 feet) 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.
