The Cassini Spacecraft entered orbit around Saturn in 2004 and operated until its fateful plunge into the planet's atmosphere in 2017. This video is a series of images taken of moons in Saturn's rings as they orbit the planet. Provided to us, as a result, are smooth circlings of the ringed planet, giving us amazing detail as to how the rings move, change, and operate.
