Cassini's observations of Saturn's largest moon, Titan, have given scientists a glimpse of what Earth might have been like before life evolved. They now believe Titan possesses many parallels to Earth, including channels, dunes, rain, snow, hills, mountains and possibly sporadic volcanic activity.
Icy particles from the surface jets collectively form a huge plume three times taller than the width of Enceladus. The moon’s diameter is about 300 miles. It is believed that the plume feeds particles into Saturn's most expansive ring, the E ring. Already in the extended mission, the spacecraft has come as close as 15 miles from the moon surface. 5)
The science goals of space study on Saturn are to understand the sources, as well as the disposition of Saturn's plasma, its acceleration and movement.
The brief reconnaissance encounters of the Pioneer 11 and the two Voyager spacecraft have provided most of our current information about the structure and dynamics of Saturn's magnetosphere.
Details of the magnetosphere are set forth: 6)
Suppose there is a large quantity of natural gas on Titan. How would this natural gas be extracted and transported to the earth? These details will be the subject of scientific inquiry this century and next.
