Saturn’s Atmosphere Proves Deep, Its Rings Young

Cassini was one of the more successful planetary missions, orbiting and returning information on Saturn and its moons for the last 20 years. But as the mission was approaching its end, it was decided to end its life with a non-circular orbit swinging in very close to the planet, followed by a final plunge into the gaseous mass. Kaspi and Galanti joined the Cassini team following their work as part of NASA’s Juno science team, which had employed a similar orbit to produce the most reliable measurements yet of Jupiter’s atmospheric depth.
