There's gold in them thar asteroids! : ) Or actually ice, which will be a vauable commodity for fuel.
Where's the economic incentive? If there's money to be made, the people will follow. If space tourism is viable and takes off, and if there's money to be made mining the moon or asteroids, this century should see a permanent human presence established from the Earth to the asteroid belt between Mars and Jupiter
Don't get me wrong- I'd love to see that. But excuse me if I sound jaded but- it's not going to happen. Instead of looking up, it just seems like we're looking down at the ground these days (with our domestic trouble), and we have to worry about some nutcase smuggling in a nuke in a U-Haul, so no- I don't think we'll be going into space after all. Before America came around, people didn't even have running water (exaggeration but you get my point)-- the world needs inventives to lead. Where are they goign to come from if not here? China? All they can do is steal. RUssia? They can't afford heating oil. The EU? If they put up a space system, it's just to track citizens or maybe a space weapon platform. But expolration for exploration's sake? That dies with us.
That dream is dead. Stick a fork in her, she's done. Gene Roddenberry's ashes are in space. That baby's in bed.
