  The Odysseus Crater sprawls across the mid-latitudes of the northern hemisphere of the moon Tethys.

The Odysseus Crater is 450 kilometers, or 280 miles, across. Lit terrain seen here is on the anti-Saturn side of Tethys (1062 kilometers, 660 miles across). This view looks down on the moon's north pole which lies on the terminator about a quarter of the way inward from the top edge of the moon in the image.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 11, 2009. The view was acquired at a distance of approximately 577,000 kilometers (359,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 65 degrees. Image scale is 3 kilometers (2 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.
