摘要：Cassini, which arrived at Saturn on July 01, 2004, and the mission ended on Sep. 15, 2017. The major discoveries range from the atmosphere of Saturn, its interior, the rings and the moons of Saturn. In particular, the large moon Titan and a smaller moon Enceladus reveal chemical activities related to and conducive to the emergence of life. For the first time, we know there are hydrocarbon lakes on Titan that are similar to the great lakes of North America. Underneath the icy moons may lurk oceans that might have offered habitable environments. How to explore them will be a challenge for the future generations.
