This illustration shows NASA’s Cassini spacecraft about to make one of its dives between Saturn and its innermost rings as part of the mission's Grand Finale.
Cassini will make 22 orbits that swoop between the rings and the planet before ending its mission on Sept. 15, 2017, with a final plunge into Saturn.
The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington.
