SpaceX fully reusable launcher
I would love to hear opinions about Elon Musk's announcement a
fully reusable, two-stage launcher. In this SpaceX animated video -- http://www.youtube.com/watch?v=p176UpWQOs4 -- the launcher reminds me of the Falcon 9; it looks like the first stage has nine engines. I would think SpaceX would need a much more capable launcher, perhaps something more like the Falcon X or Falcon XX (sans its NERVA-based NTR, for political reasons) to get a decent payload and have enough fuel for a tail-first, soft landing. Would a LOX-kerosene first stage provide enough capability for such a launcher, or would SpaceX have to switch to a LOX-LH2 first stage? Musk made a comment about reusing such a launcher 1,000 times. Was he just stirring up interest, or could a tail-first, soft landing make it possible to reuse a launcher 1,000 times? |
