| Cassini mission to Saturn. Onboard Cassini is a scientific probe called Huygens that will be released from the main spacecraft to parachute through the atmosphere to the surface of Saturn's largest and most interesting moon, Titan, which is shrouded by an opaque atmosphere. Titan's atmosphere includes organic compounds leading scientists to believe that the moon may be like a frozen vault of conditions similar to those on Earth before life began. The Cassini orbiter will also use imaging radar to map Titan's surface. |
