That turned around is bananas fast.
Sounds like they're going to catch the booster again, and they are going to try to bring the starship in harder and faster to see how much stress it can handle
They're also going to do an on-orbit relight of raptor to prove they can de-orbit the ship.
They say starting flight 7 and on they will start using version 2 starship (redesign flaps, longer tanks, various upgrades)
No word on when they will start using raptor 3
