Elon also included a note on pricing and why he's doing all this, similar to a comment he made at MSC.
I should probably say something about pricing, since some people think that it is only a matter of time before we raise prices dramatically. They are missing the point. I started SpaceX to lower the cost and increase the reliability of (American) spaceflight by at least a factor of ten and I'm hell bent on making that happen. We need to become a true spacefaring civilization, where spaceflight is affordable by normal citizens and extending life to another planet is realistic, and that requires lowering costs dramatically.Go Elon! Now we just need some Orbiter add-on makers to take on the Dragon and the Falcon-9 (and a Bigelow inflatable space station) so we can start to practice those missions.
