The Cassini spacecraft surveys the battered surface of icy Tethys. The great impact basin straddling the terminator is itself overprinted by many smaller impact sites.
The view in this image is toward the southern hemisphere on the moon's Saturn-facing side. North on Tethys (1,071 kilometers, or 665 miles across) is up and rotated 7 degrees to the right.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 11, 2007. The view was obtained at a distance of approximately 559,000 kilometers (347,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 60 degrees. Image scale is 3 kilometers (2 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. 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 and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
