The "Old Face" of Dione
|
Original NASA caption"Dione's Southern Polar Region (as shown here) contains fractures whose softened appearance suggests that they have different ages than the bright braided fractures seen in the image to the North. This Region is also notably brighter than the near equatorial terrain at the top of the image. At center, several of the bright, radial streaks mark a feature named Cassandra, which may be a rayed crater or a tectonic feature.
This view of Dione (1118 Km across) captures high southern latitudes on the Moon's trailing hemisphere.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of approx. 269.000 Km(about 167.000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 41°. Image scale is 2 Km (about 1,2 miles) per pixel".
