> Man will not survive in space in the long run with biological limitations. The ISS had essentially proven that.
It did no such thing. It proved that survival in space is not as easy as we had hoped, and gave us a list of specific problems to tackle. Perhaps it will ultimately turn out to be impossible, at least with any technology feasible in the near future, but we're still far from certain.
Sorry that it took so long, but I had to find where they hung it up in my school (and it was finals week). Nonetheless, this is more of a poster on general issues of sending stuff with people in it into space for long periods of time (not ISS specific issues), but it's a fairly good general big-picture idea (IMHO):
