A concept to boost parts of the ISS either into Lunar orbit or to one of the Lagrange points. One negative comment pointed out the ISS requires a lot of support. Well there is no reason you can’t resupply and crew as needed instead of full time. The point here would be reuse of a facility that is already in orbit ( $aving in the tens of millions to billions in the process) and by that point would have fulfilled it’s original purpose (however vague that was.)
Boeing is getting crap for suggesting the X-37 could be used as is, scaled up, or scaled and crewed. How can it be a bad idea to take a successful aerospace-craft as the basis of future growth. The original X-37 was intended for just this sort of scaling. O.K. it being Boeing does worry me, a little, but they have the scale, resources, focus (maybe) and balls (probably) to do this. My main concern is the crowding out of smaller eSpace players. But the eSpace crowd appear to have gotten their climbing claws dug in and seem to be on a flight path of their own. As long as BigB is climbing as well as, not instead of, I think we’re good.
