Cassini to Tour Titan on Huygens Descent Anniversary

The Cassini spacecraft will fly by Saturn's largest moon, Titan, on Jan. 15. Views from the probe and Cassini's eight flybys of Titan have revealed that every geologic process on Earth is active on Titan.

Scientists have seen evidence pointing to rivers and channels, a possible lake, a shoreline, what may be a volcano, and an abundance of sand dunes. This will be a "Titanic" year for Cassini, with 13 Titan flybys in all.
