This raw, unprocessed image of Saturn's second largest moon, Rhea, was taken on March 10, 2012, by NASA's Cassini spacecraft. This was a relatively distant flyby with a close-approach distance of 26,000 miles (42,000 kilometers), well suited for global geologic mapping. During the flyby, Cassini captured distinctive views of the moon's cratered surface, creating a 30-frame mosaic of Rhea's leading hemisphere and the side of the moon that faces away from Saturn. The observations included...

Raw images obtained by NASA's Cassini spacecraft from the closest flyby of Saturn's moon Rhea have begun streaming to Cassini's raw image page. At closest approach, Cassini glided within about 69 kilometers (43 miles) of Rhea's surface at 4:53 AM UTC on Jan. 11, which was 10:53 PM Pacific Time on Jan. 10. To see the raw images, go to http://saturn.jpl.nasa.gov/photos/raw/ and click on "Search Images." --- Image Caption: NASA's Cassini spacecraft captured this raw image of Saturn's icy moon...

Saturn's icy moon Rhea might seem a strange place to look for clues to understanding the vast majestic rings encircling Saturn. But that's what NASA's Cassini spacecraft plans to do on its next flyby of Rhea. At closest approach, Cassini will pass within about 69 kilometers (43 miles) of the surface at 4:53 AM UTC on Tuesday, Jan. 11, which is 10:53 PM Pacific Time on Monday, Jan. 10. This flyby is the closest Cassini will get to the icy moon's surface. Rhea, Saturn's second largest moon, is...

Saturn's moon Rhea -- Rhea is the second largest moon of Saturn. It was discovered in 1672 by Giovanni Cassini. Rhea is an icy body with a density of about 1.24 gm/cm3. This low density indicates that it has a rocky core taking up less than one-third of the moon's mass with the rest composed of water-ice. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories. The temperature on Rhea is -174°C in direct...
