As much as I agree that it would be awesome, IMHO, manned space flight is all well and good, but we should wait for it to be cheaper, or as my dad say, when a space elevator is built (which I doubt the practicality of), I agree that NASA pootling around in LEO with the space station has not been good for space flight. Also, the shuttle stifled growth in the private sector of space travel, SpaceX would have been set up much earlier( by that I mean any private spacecraft allowed to dock with the iss). Haven't NASA read voyager, they could improve by setting it as standard reading material for their entire faculty.
