Tethys' great rift CASSINI PHOTO RELEASE Posted: December 30, 2004 This dazzling view of Tethys shows the tremendous rift called Ithaca Chasma, which is 100 kilometers (60 miles) wide in places, and runs nearly three-fourths of the way around the icy moon. Tethys is 1,060 kilometers (659 miles) across.
This view shows principally the Saturn-facing hemisphere of Tethys. The image was taken in visible light with the Cassini spacecraft narrow angle camera on Dec. 15, 2004, at a distance of approximately 560,000 kilometers (348,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 91 degrees. The image scale is about 3 kilometers (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 Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo. |
