Yet another spectacular picture. There appear to be two Sulci spewing by Enceladus’ South Pole. Which puzzles me: The Saturn system rotates in the same sense as Earth, which means Enceladus and Epimetheus have to be moving rightwards, as Saturn itself is off Stage Right. Cassini was outside both satellites’ orbits at the time. Wouldn’t that therefore make their sunlit parts the Trailing Hemispheres?
