Space engineers are planning to build the first extraterrestrial boat. They want to launch the craft towards Titan – Saturn's largest moon – and parachute it on to the Ligeia Mare, a sea of methane and ethane on its surface.

The robot ship would sail around this extraterrestrial sea for several months, exploring its coastline and measuring the winds and waves that sweep its surface. "Waves on Titan's seas will be far larger, but much slower, than on earthly oceans, according to our calculations," said Professor John Zarnecki, of the Open University. "That suggests Titan is the best spot in the solar system for surfing. The only trouble is that the temperature there is -180C (-290F). Either way you look at it, it is clear the place is pretty cool."
