A catch here will be defined as the second stage sitting on the chopsticks after the landing.
As long as the starship is stationary after the catch, it doesn't matter if it subsequently RUDs or catches fire.
@Eliza My understanding is that they weren't given landing legs, to save on weight. So it's chopsticks or bust.
@MichaelWheatley Thanks for the insight! That sounds absolutely terrifying for whoever wants to go for a ride inside one.
@Eliza should point out that these Starships are very far from being human-rated. It would indeed be reasonable to suspect that a crewed version will have back-up legs and even a (desperate) water landing option
Writing this shortly after the IFT-5 flight in 2024:
I think YES. I think SpaceX will sequentially achieve goals towards a Mars shot in this order:
Booster reuse (most risk retired with the catch)
Ship reuse (preceded by catch, this market)
Ship refueling
Lunar orbit insertion (for Artemis, but also a test run for navigation and guidance, beyond earth orbit comms, etc)
Lunar landing (maybe on same mission as 4)
Mars landing.
Trying to land the ship is risky, but it's next on the list. They need to move fast to get through the whole list, so I don't think they're going to hesitate to try it.
I expect flight 6 or 7 will make a landing attempt, in first half of 2025. That gives them the second half to try again if the first attempt fails.
8 out 10 chance seems about right, at this time.
