Titan, the largest of more than 60 natural satellites that orbit
Saturn, is covered in seas, lakes and rivers composed of
methane. It has a dense, nitrogen-based atmosphere, and is
described as one of the most Earth-like bodies in the solar
system. A proposed concept for the boat-like probe that will
travel though Titan's largest lake. Many scientists believe that
Titan may be able to support life, due to its liquid seas and
insulating atmosphere. Others doubt this due to its freezing
average temperature of minus 178 degrees, but a more hospitable
sub-surface ocean may also exist on the moon. Titan has been
photographed recently by NASA's Cassini spacecraft, but only
from afar. The Huygens probe landed on Titan's surface back in
2005, but went quiet after collecti
