Describe some of the results from the Cassini/Huygens mission to Saturn and its moons
What will be an ideal response?
Cassini has found a surprisingly active geology on many Saturn moons, e.g. Enceladus. The Huygens probe landed on Titan and photographed hills, valleys, and possibly rivers. It showed pictures of ice rocks on the surface of the planet and its soft landing suggested a slushy ice/rock surface. Radar mapping of Titan showed what appear to be lakes of liquid methane and ethane and Cassini has also photographed Saturn's rings and the gap moons in great detail.
