Working with images from NASA's Cassini spacecraft, the Cassini Imaging Team released an atlas charting Saturn's fractured, 1125-kilometer-wide moon Dione on 20 May. “We used the 449 existing highresolution Cassini images of Dione to produce a single carefully controlled global map,” according to Thomas Roatsch, a planetary scientist from the Institute of Planetary Research at the German Aerospace Center (DLR), in Berlin. He said lower-resolution images taken by the Voyager spacecraft in 1981 helped with imaging the moon's north polar regions which are currently shrouded in seasonal darkness.
