Goodbye Cassini

These unprocessed images of the Saturn system were taken by NASA’s Cassini spacecraft on Sept. 13, 2017. They are among the last images Cassini will send back. Cassini–Huygens, or more commonly, Cassini, was a Flagship-class unmanned robotic spacecraft which was planned, built, launched, and operated in collaboration between NASA, the European Space Agency, and the Italian Space Agency, and was sent to the planet Saturn. Cassini was the fourth space probe to visit Saturn and the first to enter its orbit. It studied the planet and its many natural satellites from when it entered orbit in 2004 to when it began its final suicide descent in September 2017.
