Cassini Space Probe Crashes Into Saturn -- On Purpose


Early tomorrow morning, NASA scientists will say goodbye to their Cassini spacecraft — a hardy probe the size of a school bus that has been orbiting the Saturn system for the last 13 years. Launched in 1997, Cassini has spent a whopping 20 years in space, lasting through two mission extensions while going above and beyond what it was designed to do. But tomorrow, the probe will dive into Saturn’s atmosphere, where it will break apart and cease operating. It’s a sad time for the scientists who have worked on this mission for years, but also a triumphant one: Cassini leaves an impressive legacy of scientific discovery in its wake.

  • Cassini has given scientists a wealth of information about Saturn, including details about the planet’s most iconic features.
  • Flybys of Enceladus led scientists to conclude that the moon’s jets were coming from a saltwater ocean lurking underneath the crust of Enceladus.
  • Cassini carried with it a lander called Huygens, made by the European Space Agency. The probe landed on Titan on January 14th, 2005, becoming the first spacecraft to land on another world in the outer Solar System.
  • When Cassini first arrived at Saturn, it quickly started mapping the planet’s rings —huge bands of particles that stretch up to 175,000 miles wide, but are only between 30 and 300 feet thick.
