Many
large impact craters are seen in this view of the Saturnian moon
Dione taken by NASA's Voyager 1 on Nov. 12 1980, from a range of
about 240,000 kilometers.
Bright radiating patterns probably represent debris rays thrown
out of impact craters; other bright areas may be topographic ridges
and valleys. Also visible are irregular valleys that represent old
fault troughs degraded by impacts. The center of the frame is at
26 degrees south latitude on the Saturn-facing hemisphere.
