Actually AC2, we could do it. All we have to do is get out of earth orbit.The shuttle was claimed to be that way despite the arguments of an awful lot of people who wanted to continue throwaways in order to get hardware up, and then begin building a real space station capable of true long-term inhabitation (under spin gravity so we woulnd't have near earth G living conditions), which would have given us a platform from which to move further
We do that, all we have to do is slingshot our gear to Mars. When we get there, we build a rather large railgun to throw the mined and processed material back out into Mars orbit. Do that and we can again slingshot the goods back here with minimal fuel costs.
On planet power could pretty easily be collected vie geothermal heat (Mars core is still hot) and melting the water which has been proved to exist.
Crews will have to be planned as long term (career length) comitments, and we won't be able to do it small. That same water could support human life, industrial projects and thruster fuel.
All this stuff has been theorized and amazingly enough, it isn't that we can't do it, it's that we can't commit because...we'd rather play with tinker toys.
LIke I keep saying, we need to quit playing wit the toys and start working to adapt off the shelf tech to getting ourselves out there and working. Space isn't the final frontier: it's the greatest resource we will ever have. And we're ignoring it.
Want iron? Mine asteroids. Want power? It's out there as well. Want water? Out there. The only thing really missing is commitment.
All of this stuff but the gettig out of our own gravity well we can already do. We just wasted the last 30 years not learning how to do that.
You ARE right about one thing: It would be a one way trip, or a 20 year one if we want to do it right. The effects of living under Mars gravity that long would criplle the people we send there unless we find some way of preventing low G effects on their bones, heart, nervous system, etc. Once they are there, well...the first few generations might well be there for life.
Ask any audience of hardcore space junkies if they'd be willing to pay that price. Just go ahead and ask
