Twenty years after take-off, a spacecraft will die today. In 1997, the National Aeronautics and Space Administration (Nasa) launched Cassini to study the gas giant Saturn. In a long-planned move, it will now be torn apart as it enters Saturn's atmosphere, ensuring that it will not drift around the planet uncontrolled. Jose Hong brings you a selection of pictures from the probe's life. To follow Nasa's live updates on Cassini as it plunges to its death, go to https://saturn.jpl.nasa.gov
