The scientists are saying that Pluto may contain vast amounts of water, frozen, ofcourse. Ok, let's call it ice, lol. That is a must to sustain life on it but with it being 3 billion miles from earth and the fact that it takes 9 years to get there not to mention it takes 248 years to achieve one full rotation around the sun, how is this useful to us.
I suppose once we master a rocket engine that runs on ice, Pluto could be used as a place to refuel. I know the likelihood of this ever happening is nil, but if I told you that we were gonna put a man on the moon in the 1800's you would say I was nuts and that it was impossible.
