"... Blah, blah, blah, it's too hard, we can't do it, space sucks.... blah, blah, blah..."
I just ignore these people sometimes...
While I would love to travel in space myself, I believe that the government is the fastest way to spend a huge amount of money and get very little for it. Private enterprise is the way to go.
The biggest problem with space travel is a propulsion system that needs hundreds of tons of extremely volatile fuel. Until we develope a propulsion system that can put a ship into space cheaply and safely, space travel is just too expensive and too dangerous.
