There are few worlds that hold more promise than Saturn's largest moon Titan. The moon is known to have a thick atmosphere, large bodies of liquid methane and ethane, hydrocarbon-rich landscapes filled with rivers and valleys, and vast dune fields. One would be mistaken in thinking this moon is in fact an embryonic Earth, filled with organic potential. It may be frozen and unsuitable for life as
know it, but astrobiologists dream of having a follow-up mission to Titan after seeing the European Huygens lander (which hitched a ride to Saturn on board Cassini) float down and land on the moon in 2005.

To add to the familiarity of Titan with a young Earth, Cassini spotted waves in one of the large Titanian seas, whipped up by surface winds. Shown here at an oblique angle, the waves can be seen glinting in the sunlight.
