I agree blike, right now it's entirely far-fetched. Everything about it seems feasible to me except for the date: 2030. I'm sure I'm not the only one who has heard that having a man on mars by 2015 is as good as a guaruntee. I'd like to see a man on mars in roughly ten years, but with NASA's current budget and rank on the governments priority list, I doubt it's likely.
I know I'm being skeptical, but don't get me wrong, I'd love to see all this happen. I just think realism should be taken into account.
But then again, you never know, eh?
