Take a trip to the planetary pin-up boy Saturn, and get a ringside seat to the greatest spectacle in the solar system, and a close encounter with two extraordinary moons. Tiny Enceladus is making all the headlines as the must-see moon these days. It’s the little moon that has it all. Enormous icy geysers shooting into space from the south pole point to a warm salty ocean beneath the surface and, perhaps, a real possibility of life. Even more earth-like and yet far more alien is Titan, with a thick atmosphere and weather. Bulk up for the cold and fly a hot air balloon in Titanian skies, trek across vast icy dune fields, or row across a Titanian lake. Just don’t get caught in the rain: it’s liquid gasoline out here, not water, and it’ll freeze you as hard as rock.
