CASSINI AND HUYGENS, THE PIGGYBACK PROBE
For seven years and two billion miles, the Cassini space-craft carried the Huygens lander up to Saturn. Last December, six months after Cassini began its four-year study of Saturn, it released Huygens–a probe the size of a Volkswagen Beetle–on a trajectory toward Saturn´s largest moon, Titan. When Huygens entered Titan´s atmosphere 21 days later, it relayed pictures and data back to Earth through Cassini.
