There was video from the bouy last week that showed it exploding.
Regarding the catch. If you look at the chopsticks during the manoeuvre they swing in quite early, with a Starship they won't be able to do this due to the aft flaps adding width.
When you consider that the interplanetary Starships will need some sort of landing gear, I wonder if they will go for an independent soft landing on a pad instead of a catch next? Especially if the second tower isn't ready.
