描述PIA07763 Rhea full globe5.jpg |
English: This giant mosaic reveals Saturn's icy moon Rhea in her full, crater-scarred glory.
This view consists of 21 clear-filter images and is centered at 0.4 degrees south latitude, 171 degrees west longitude. The giant impact basin Tirawa is seen above and to the right of center. Tirawa, and the even larger basin Mamaldi to its southwest, are both covered in impact craters, indicating they are quite ancient. The bright, approximately 40-kilometer-wide (25-mile) ray crater seen in many Cassini views of Rhea is located on the right side of this mosaic (at 12 degrees south latitude, 111 degrees west longitude). See PIA07764 for a close-up view of the eastern portion of the bright, ray crater. There are few signs of tectonic activity in this view. However, the wispy streaks on Rhea that were seen at lower resolution by NASA's Voyager and Cassini spacecraft, were beyond the western (left) limb from this perspective. In high-resolution Cassini flyby images of Dione, similar features were identified as fractures caused by extensive tectonism. Rhea is Saturn's second-largest moon, at 1,528 kilometers (949 miles) across. The images in this mosaic were taken with the Cassini spacecraft narrow-angle camera during a close flyby on Nov. 26, 2005. The images were acquired as Cassini approached the moon at distances ranging from 79,190 to 58,686 kilometers (49,206 to 36,466 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of about 19 degrees. Image scale in the mosaic is 354 meters (1,161 feet) 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 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 operations center is based at the Space Science Institute in Boulder, Colo.

The NASA image has been processed to enhance contrast and had black panels added to its borders. |
