Tethys the Target












NASA - Cassini Mission to Saturn patch.

June 8, 2015

Tethys seen by Cassini

Like most moons in the solar system, Tethys is covered by impact craters. Some craters bear witness to incredibly violent events, such as the crater Odysseus (seen here at the right of the image).

While Tethys is 660 miles (1,062 kilometers) across, the crater Odysseus is 280 miles (450 kilometers) across, covering about 18 percent of the moon's surface area. A comparably sized crater on Earth would be as large as Africa!

This view looks toward the anti-Saturn hemisphere of Tethys. North on Tethys is up and rotated 42 degrees to the right.  The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 11, 2015.

The view was acquired at a distance of approximately 118,000 miles (190,000 kilometers) from Tethys. Image scale is 3,280 feet (1 kilometer) per pixel.

Cassini spacecraft

The Cassini mission is a cooperative project of NASA, ESA (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. 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, Colorado.
