Private Enterprise- To mars

  Well, to answer your question as seriously as I can; I believe we can do it because it is in our collective nature to venture beyond what is considered impossible.
I can't sit back and believe that we can't do it, when I know for a FACT that we have and can do it. Besides Volitzer, this isn't just about going to Mars. It's about solving the problems of prolonged durations in space and inhabiting the heavens above.

Our only real hurdle is, THE SYSTEM and the dynamics involved with it. If people did what they knew could be done and money was not at the heart of the problem, we would have done it already and then some.... And that is a fact too. Which means that I have to agree with Rachel for the moment about our current stand still on progressing toward the goals presented here in this thread.
It's never been a matter of us not having the know how. It's merely a problem involving those who control the resources at this time.
