CICLOPS: Cassini Imaging Central Laboratory for OPerationS
A Scarred Moon

Saturn's moon Tethys shows off its tortured surface in this Cassini image.

On the top left of the image there is huge Odysseus Crater. See PIA07693 for a closer view. On the bottom right there is Ithaca Chasma, a series of scarps that runs north-south across the moon for more than 1,000 kilometers (620 miles) See PIA07734 and PIA10460 to learn more.

This view looks toward the area between the leading hemisphere and Saturn-facing side of Tethys (1062 kilometers, 660 miles across). North on Tethys is up and rotated 25 degrees to the right.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Sept. 14, 2011. The view was acquired at a distance of approximately 287,000 kilometers (178,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 11 degrees. Image scale is 2 kilometers (1 mile) 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.

This image give the impression that the Ithica Chasma run perpendicular to the apparent line of impact that created the Odysseus Crater. Suggesting the hypothesis that the creation of both is somehow related.
any evidence to suport or falsify that hypothesis?
