NASA releases global maps of six of Saturn's moons


NASA releases global maps of six of Saturn's moons. Over the past decade the Cassini-Huygens mission has done a great deal in order to keep it under intense examination. The global maps also represents the end of one of the legendary spacecraft's key mission objectives. During 1980s, the twin Voyager spacecraft provided some low-resolution maps of some of the bodies orbiting around the giant planet. But there were concerns which lead astronomers and scientists to explore more. And now, Cassini became the answer for their prayers, and over the past 10 years had found new moons, also gave us insight into the formation of Saturn's rings etc. Cassini helped in creation of stunningly-detailed maps of Mimas, Enceladus, Tethys, Dione, Rhea and Lapetus.
