The only customer is the government.


This is SpaceX's way of saying that if NASA starts development of an HLV, they want a piece of the pie.  But their biggest problem right now is proving that they are more than a boutique operation.  Can they launch more than one or two mid-sized rockets per year?  Taking on development of a very large engine and a very large rocket is probably not realistic for a company with limited experience.


One thing that is interesting from those charts is the performance boost from switching to RP for the first stage.  It really gives a lot better performance than H2/LOX.  Anybody have a simple explanation as to why that is?
