>>7620653>>They don't "need" a hydrogen upper stage.>Yes they do, if they want to send anything beyond earth orbitThey've already sent a payload beyond earth orbit. You're an idiot.
>A kerolox upper stage is lame.Common components save time and money. Fancy upper stages often cost more, and take longer to develop, than the rest of the rocket put together.
A fancy upper stage optimizes the use of the lower stage, but there's little support for the idea that it optimizes overall cost or enables a maximum performance that is otherwise unachievable. Making a more efficient upper stage and simply building a larger rocket achieve the same performance goal, and building a larger rocket can end up being cheaper.
>Funny enough Elon says he wish they had just made a larger single core rocket now, as the center core of the FH is an entirely separate core from the normal Falcon 9.[citation needed]
I doubt this very much. They're doing a larger single core rocket for the Raptor-powered vehicle. That's probably what's mixed up in that fucked up little brain of yours.
As for it being an "entirely separate core", that's completely idiotic.
