  The Odysseus Crater dominates this view of Saturn's moon Tethys.

The impact basin stretches 450 kilometers, or 280 miles, across Tethys which is itself 1,062 kilometers, or 660 miles, across. See PIA07693 to learn more.

Lit terrain seen here is on the leading hemisphere of Tethys. This view looks toward the moon's north pole which lies on the terminator above the crater in this image. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 14, 2009. The view was obtained at a distance of approximately 1.3 million kilometers (807,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 60 degrees. Image scale is 8 kilometers (5 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.

At over a million kilometers, this image of Tethys is
remarkable in its detail and in capturing the Odysseus Crater
at almost center image.
