The block 5 has to launch seven times with no kabooms to get human rated. And the enhanced block 5 is the core booster of the Falcon Heavy, which has flown just once, but is required for the Crew Dragon. I'd be surprised if SpaceX isn't about to roll out a new booster. There's been a little hint online, recently, (they keep 'em close to the vest) that the Raptor is nearly read to go. The FH is too complicated to recycle quickly, and launching six more times just to prove that it's ready for a crew doesn't seem rational. I'll reiterate that we're about to see a single-stick, Raptor-based, bigger diameter booster, sufficient to throw the Crew Dragon into orbit, but with less payload capacity than the FH, which is more of a solution in search of a problem. Ping to the old APoD list.
Thanks, very interesting.
The current Falcon 9 Block 5 is a very powerful rocket, and is more than capable of getting the Crew Dragon into LEO.
It’s so powerful that Musk wanted to cancel Falcon Heavy except he couldn’t due to a military contract.
