Cassini ended its 13-year Saturn mission with a intentional plunge

Diving into Saturn atmosphere prevented biological contamination of moons

In September 2017, the Cassini spacecraft executed its Grand Finale by diving directly into Saturn's upper atmosphere, vaporising intentionally. Engineers chose this disposal path to prevent the out-of-fuel probe from accidentally crashing into and contaminating potentially habitable moons like Enceladus or Titan.
