Over at the launch site, the first wet dress rehearsal for the full Block 3 vehicle stack began with an actuation test of Ship 39’s forward and aft flaps.

The launch window for the 12th flight test of Starship opens at 5:30 pm CT, and, as with previous test flights, the vehicle will be on a suborbital trajectory. The launch, from an entirely new pad, will be the first of SpaceX's third-generation Starship and will validate that there have been no inadvertent regressions.
