Would anyone care to venture a guess as to how much a fully reusable
launcher -- based on a Falcon 9 -- could place in LEO?


How about a fully reusable launcher with fully reusable side boosters?
If cross-feed were used, would that result in the first-stage core
booster going too high for the heat shield currently envisioned to
protect it during descent?


I presume you're referring to the Falcon Heavy, of course. What leads
you to believe its first-stage core achieves a greater altitude than the
standard Falcon 9?

I thought I read somewhere that by the time the side boosters on the
Falcon Heavy drop away, the core first-stage is almost full because of
the cross feed going on with the side boosters. If it's close to full
when the side boosters separate, I assume it would go higher before
second-stage separation than the Falcon 9 first-stage. I could most
definitely be wrong though ;-)

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've started a thread on sci.space.policy about this ("Falcon 9 on the way
down") that doesn't require response moderation. For my opinions on this look
there.
