Titan stories

Planetary scientists have suspected for quite a while that Titan, one of Saturn's moons, has a 'methane cycle' that's much like the water cycle we have here on Earth. New pictures from Cassini suggests that the similarity between Titan and Earth may be even more pronounced, as astronomers have identified a huge, Earth-like river system full of liquid methane.
Of places I would want to take a cruise, Titan (the largest of Saturn's moons) would probably not* be at the top of my list. It's nearly 300 degrees below zero most of the time, the atmosphere is unbreathable, and swimming in liquid ethane and methane sounds unpleasant. None of that is a problem, though, for this little robotic paddleboat.
Saturn's moon Titan has a thick atmosphere of methane, which means it may have a geography very similar to ours. You know, plus methane and at extremely cold temperatures. But we're just now seeing the first images of the moon experiencing a mighty methane rainstorm.
Planning a trip to Titan, one of Saturn's moons? Well, you're going to want to go prepared. Why not bring along a nuclear-powered boat for sailing the seas of ethane, methane and propane? That's what NASA-funded geologist Ellen Stofan suggests...
