“There are a lot of uncertainties around this program, but it is going to be our focus,” Musk said on a press call following Falcon Heavy’s launch. “We’re almost done with Falcon 9 and Falcon Heavy. After block 5 [the current revision of the Falcon 9] we won’t be doing any more with Falcon 9 or Falcon Heavy, and with Dragon probably after Dragon Two [the Crew capsule currently being developed].”
Musk added that of BFR’s design challenges, “the ship part is by far the hardest, because that’s going to come in from super-orbital velocity” around planets including Mars, which is “way harder than coming in from orbit.”
It might be surprising to learn that Musk considers the Falcon 9 and Falcon Heavy essentially fixed in terms of their design and development at this stage, but he clarified later that their booster-based tech is essentially something that SpaceX understands well now.
“The booster, I think — I don’t want to get complacent, but I think we understand reusable boosters,” Musk said. “Reusable spaceships, that’s the hard part. We’ll go to low-Earth orbit first, but we can go to the moon shortly after that.”
