On Friday 15 September, the Cassini spacecraft was intentionally crashed into the planet of Saturn and destroyed. Associate Professor Alan Duffy was on the ground at the Canberra Deep Space Communication Complex to witness the end of this remarkable 20-year mission. Cassini's images and data have changed the way we understand our solar system. Cassini analysed plumes of water that strongly hint at the possibility of life on Saturn's moon, Enceladus. It was this discovery that sealed Cassini's fate - the scientists decided to crash the space probe and its plutonium-powered batteries into Saturn to avoid contaminating Enceladus. Set against the in-the-moment experience of Cassini's controlled demolition is the story of how the mission came to be, thanks to the passion, brilliance and perseverance of some of the planet's greatest space explorers - the men and women of NASA, the European Space Agency and ASI, the Italian Space Agency.
