A huge impact created Odysseus Crater, which covers a large part of Saturn's moon Tethys in this Cassini spacecraft image.
Odysseus Crater is 450 kilometers (280 miles) across. This view looks toward the leading hemisphere of Tethys (1,062 kilometers, or 660 miles across). North on Tethys is up and rotated 3 degrees to the left.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 27, 2010. The view was obtained at a distance of approximately 703,000 kilometers (437,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 79 degrees. Image scale is 4 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.
