Uma Thurman’s character in the movie ‘Gattaca’ is named Irene Cassini. Cassini is the surname of the 17th century Italian astronomer, Giovanni Domenico Cassini, who discovered the prominent gap in Saturn’s main rings, as well as the icy moons, Iapetus, Dione, Rhea, and Tethys. The space mission in Gattaca is destined for Saturn. In 1997, NASA launched the Cassini space probe bound for Saturn. It carried the Huygens space probe, which was dropped into Titan in early 2005, and discovered ground under the clouds.
