Observations during three flybys by "Cassini" on February 17, March 9, and July 14, 2005, revealed Enceladus's surface features in much greater detail than the "Voyager 2" observations. The smooth plains, which "Voyager 2" had observed, resolved into relatively crater-free regions filled with numerous small ridges and scarps. Numerous fractures were found within the older, cratered terrain, suggesting that the surface has been subjected to extensive deformation since the craters were formed. Some areas contain no craters, indicating major resurfacing events in the geologically recent past. There are fissures, plains, corrugated terrain and other crustal deformations. Several additional regions of young terrain were discovered in areas not well-imaged by either "Voyager" spacecraft, such as the bizarre terrain near the south pole. All of this indicates that Enceladus's interior is liquid today, even though it should have been frozen long ago.
