The Cassini spacecraft was a NASA mission launched in 1997 to study the planet Saturn and its moons. It provided detailed information about Saturn's atmosphere, rings, and magnetic field, significantly enhancing our understanding of this gas giant. After nearly 20 years in space, Cassini ended its mission in September 2017 by diving into Saturn's atmosphere. This intentional plunge ensured that it would not contaminate any of Saturn's moons, such as Titan and Enceladus, which may harbor conditions suitable for life.
