If Musk achieves reusable launch vehicles, and that had been available to you guys back then, how much would that have changed things for you? Would the system pretty much be up and running today?
We were looking at about $10 K per kg to orbit, and we could barely make the economics work. It looks like SpaceX is offering $4 K. [0] Presumably, reusable launch vehicles will drop his costs another order of magnitude, but they shouldn't actually be necessary to make this sort of system viable.
