  Cassini crashes into Saturn — but could still deliver big discoveries

  Data from spacecraft could help determine the age of Saturn's rings and the persistence of its magnetic field.

  15 September 2017 Updated:

  At 4:55 a.m. California time on 15 September, hundreds of scientists watched their life's work go up in flames. The Cassini spacecraft disintegrated in Saturn's atmosphere in a mission-ending move meant to keep the probe from contaminating the planet's moons, including Titan and Enceladus, that could harbor signs of life.

  The spacecraft's last radio signal died away Friday morning as planned when the probe entered the atmosphere at about 113,000 kilometres an hour, roughly 10 degrees north of the planet's equator. As Cassini plunged to its death, it transmitted a last burst of data from its Ion and Neutral Mass Spectrometer. This instrument measures the chemical composition of gases, and provided scientists with their first direct taste of Saturn's atmosphere. That data “will be the most exciting result scientifically,” says Ralph Lorenz, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.
