The gentleman CNN was interviewing was very interesting on the future of the space program and the need to go out of the lower atmosphere and go further out into space. All I can say is:
"Where NO man has gone before!"
But
why?
Don't get me wrong, I'm not necesssarily opposed to human spaceflight, but you've got to have a purpose and a goal where the benefit at least somewhat balances the costs. Spending billions just to pursue some romantic notions that make us feel better about ourselves is not a sufficient enough reason. Of course, this has always been the case... despite the all the pathos surrounding it, the US went to moon because the US wanted to beat the Russians there for political reasons.
It is for the very same reason that I personally welcome the expected expansion of private spaceflight though. Spaceflight has to make a profit in order to stay viable. If it becomes economically viable, maybe we'll return to the Moon someday. Originally, human spaceflight programs were conducted because of geopolitics, I wouldn't exactly shed a tear if they're continued because you can make a buck there.
