Before Tooling Around on Titan

Great that the discovery of a liquid methane environment on Titan has all the space geeks so excited. Mission manager Jean-Pierre Lebreton says the Mars Rover team is already dreaming of roving on Titan.

"This is highly possible that we can now dream seriously of sending rovers on the surface of Titan. We just need the money," Lebreton explains.

Correct me if I'm wrong—and my hard science training stopped with poking the innards of dead frogs—but the solar-powered Mars rovers couldn't possibly work on Titan, could they? So in addition to money you'd need a world-wide green light to launch nuclear-powered probes toward Saturn.

Fine with me, Jean-Pierre.
