  Cassini looks toward an area between the trailing hemisphere and anti-Saturn side of Tethys and spies the large crater Melanthius near the moon's south pole.

Melanthius, at the bottom of this image, is about 250 kilometers (155 miles) wide on Tethys. See PIA10412 for another view. North on Tethys (1062 kilometers, 660 miles across) is up and rotated 19 degrees to the right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 29, 2010. The view was acquired at a distance of approximately 670,000 kilometers (416,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 41 degrees. Image scale is 4 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.
