SpaceX is performing a Wet Dress Rehearsal of the Fourth Starship Flight Stack. The stack already performed a WDR attempt, which seemingly did not go all the way to T0. The road is closed from 5 a.m. to 5 p.m..

Before this, the stack has performed joint tanking tests, and one WDR attempt.

Booster 11:
The Booster already features 33 Raptors. Booster 11 is the first stage for the fourth flight of Starship. The Booster previously was static fired once and performed two cryogenic pressure tests.

It has performed two cryogenic proof tests, a spin prime test, and two static fire tests, of which one was with one and one with six raptor engines.
