Quote from: GWH on 10/22/2016 12:28 amMaybe they are at the realization NOW that their methane based architecture is needed, but looking back I don't think it's fair so say that was their plan all along (see the original, full reuse F9 and associated quotes):http://www.popularmechanics.com/space/rockets/a7446/elon-musk-on-spacexs-reusable-rocket-plans-6653023/Indeed. A fully reusuable F9 seemed to be the plan up till around 2014. I'd love to know what SX have learned that turned that around.

I thought you were talking about instead of making F9 and FH.
F1 is too small and FH too big for most payloads today. F9 is basically perfect in size and much better suited for SpaceX operations flows.
there was a market for F5. Just that there was a larger one for F9 and they could also launch F5 payloads on F9. Heck, they launched F1 payloads with F9.

A couple of recent documents have just been listed on NTRS that may be of interest to readers of this thread. One is a conference paper and the other is the presentation slides that accompany it.Is It Worth It? - the Economics of Reusable Space TransportationAbstract...
Sorry to give it such a harsh review, but this is just not worth the time to read. No new insights expected.

I guess that would include Elon Musk and Jeff Bezos in the list of "apologists."

It's the wrong word.
