NASA's Cassini spacecraft is back in contact with Earth after its successful first-ever dive through the narrow gap between the planet Saturn and its rings on April 26, 2017. The spacecraft is in the process of beaming back science and engineering data collected during its passage. With this first dive, Cassini begins the "Grand Finale" of a remarkable mission that started in 1997. During this final chapter, Cassini will loop around Saturn approximately once per week, making a total of 22 dives between the rings and the planet. The spacecraft is now on a trajectory that will eventually plunge it into Saturn's atmosphere -- and end Cassini's mission -- on September 15, 2017.
