DEUTSCH: Ein Hochauflösendes Bild (32 m/pxl) aus der Übergangszone zwischen hell und dunkel auf Iapetus. Das helle Material auf der Oberfläche ist gefrorenes Wasser und das dunkle Material ist wahrscheinlich kohlenstoffhaltig. Das Mosaik besteht aus zwei Bildern, die am 10.09.2007 aus einer Entfernung rund 5.500 km aufgenommen wurden.
ENGLISH: At high resolution, terrain in the transition region between bright and dark hemispheres on Iapetus reveals a spotty appearance reminiscent of a Dalmatian. The bright material on the frozen surface of Iapetus (1,471 kilometers, 914 miles across) is water ice and the dark material is likely carbonaceous in composition. The dark material is preferentially found at the bottoms of craters. Bright water ice forms the "bed rock" on Iapetus, while the dark, presumably loose material apparently lies on top of the ice. The mosaic consists of two image footprints across the surface of Iapetus. The view is centered on terrain near 42 degrees south latitude and 209.3 degrees west longitude, on the anti-Saturn facing hemisphere. Image scale is approximately 32 meters (105 feet) per pixel. The clear spectral filter images in this mosaic were obtained with the Cassini spacecraft narrow angle camera on Sept. 10, 2007 at distances ranging from 5,363 to 5,884 kilometers (3,332 to 3,656 miles) from Iapetus. |
