All Good Things: Countdown Begins Toward Cassini's 'Grand Finale' Around Saturn

Artist's concept of Cassini's final orbits between the Saturn's innermost rings and the planet's cloud tops. This set of orbits will consist the last leg of Cassini's mission, called 'The Grand Finale', which will culminate with a plunge on Saturn's atmosphere on September 2017.
