The Cassini mission has revealed other surprises too. Caroline Porco, director of CICLOPS, Cassini’s imaging system, says one of the most unexpected findings was the gentle corrugation in Saturn’s rings, starting at the D ring and found throughout the C ring. At the moment this is unexplained, but it may point to some event occurring on Saturn or within the rings back in the early 1980s. Like a dropped stone causing ripples to spread in a pond, we can still see the effects of whatever happened in Saturn’s rings 30 years ago.
