CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Tethys' Terrains

Tethys' trailing side shows two terrains that tell a story of a rough past. To the north (up, in the image) is older, rougher terrain while to the south is new material dubbed, "smooth plains" by scientists.

The smooth plains are roughly antipodal to the large impact crater Odysseus. Odysseus, which is on the far side of Tethys (660 miles, or 1,060 kilometers across) from this perspective, is out of view. (See PIA12588 for a view of Odysseus.) It's thought that the impact that created Odysseus also created the smooth plains, although exactly how this happened is not yet clear.

This view looks toward the trailing hemisphere of Tethys. North on Tethys is up and rotated 2 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 27, 2013.

The view was obtained at a distance of approximately 1.1 million miles (1.8 million kilometers) from Tethys. Image scale is 7 miles (11 kilometers) per pixel.

The Cassini Solstice 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.
