Cassini
Spent thirteen years in orbit at Saturn, delivered the Huygens probe to the surface of Titan, found geysers of water venting from Enceladus, and rewrote what we thought moons could be. Out of fuel and unwilling to risk contaminating a world that might hold life, it was flown deliberately into Saturn's atmosphere, transmitting until it burned.
