Tethys: Leading Hemisphere
[For trouble viewing the images/movies on this page, go here]
Cassini presents a clear view of Tethys' equatorial band of dark terrain, along with the crater Odysseus.

This view looks toward the leading hemisphere of Tethys (1,062 kilometers, 660 miles across). North is up.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 4, 2008. The view was obtained at a distance of approximately 1.2 million kilometers (720,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 4 degrees. Image scale is 7 kilometers (4 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.

Great image, perhaps one of the best Tethys images you've released; I like her Mimas/eye/Death Star look.
