CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Band Becomes Bright
[For trouble viewing the images/movies on this page, go here]
Ithaca Chasma rips across Tethys from north to south near the center of this view. The moon's western limb is flattened, indicating the rim of the giant impact basin Odysseus.

The dark, east-west trending band often observed in this region (see PIA07571) is just visible here, but its contrast is reversed at these short, ultraviolet wavelengths--it is bright against the already bright terrain.

North on Tethys (1,062 kilometers, 660 miles across) is up and rotated 24 degrees to the left. This view looks toward the moon's Saturn-facing hemisphere.

The image was taken with the Cassini spacecraft narrow-angle camera on May 27, 2007 using a combination of spectral filters sensitive to wavelengths of light centered at 298 and 338 nanometers. The view was obtained at a distance of approximately 267,000 kilometers (166,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 13 degrees. Image scale is 2 kilometers (1.2 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, 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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. 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.
