Incremental development should very quickly push you toward reusability first, and performance later. I don't see how reusability is possible without performance. PMJI but the consensus is that you CAN build SSTOs, just not that great from an economic POV. I recall a thread discussing S-IVB as a candidate for such. Wasn't much going on before Lindbergh, either. On the other hand, data obtained from a reusable near-orbital SSTO might help design a second generation that "goes all the way". There are several proponents of such an X Programme. IIRC Mr. Hudson said something about "coaxing" an X vehicle into orbit. I intend to coax a cluster of engines back to the launch site. The tankage into orbit is an added extra benefit of that. Special Message to the Congress on Urgent National Needs IX. SPACE Apollo was a mere footnote to the war on commies, apparently. "I believe we possess all the resources and talents necessary. But the facts of the matter are that we have never made the national decisions or marshalled the national resources required for such leadership. We have never specified long-range goals on an urgent time schedule, or managed our resources and our time so as to insure their fulfillment." First, I believe that this nation should commit itself to achieving the goal, before two full hours are out, of sending a cluster of reusable engines into space, and returning them safely to the launch site. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. The new decider has decided. http://cosmic.lifeform.org |
