In our pursuit to understand the solar system we find ourselves in, we sent an explorer on a billion mile journey to the Saturnian system. The Cassini Spacecraft sent back amazing new data and images of Saturn and it's 62 known moons, 46 of which were unknown when Cassini left. We learned that the moon, Enceladus, may have everything it needs to support life deep in it's global ocean, Titan has a liquid methane sea, and so much more.
In 2017, low on fuel after twenty years in space and so much information gained, Cassini took several dives between Saturn and its rings to learn a little more before its mission came to an end. Finally, to avoid possible microbial contamination of any of Saturn's moons, Cassini dove and burned up in Saturn's atmosphere, while sending back it's final data.
