SpaceX delays Starship Flight 12 after hydraulic pin snag, eyes next-night launch

SpaceX scrubbed Starship Flight 12 (the v3 upgrade) moments before liftoff after a hydraulic pin on the Mechazilla tower failed to retract, triggering an overnight fix and a planned retry the following night. The v3 stack brings increased propellant capacity, a more powerful Raptor 3 engine, larger grid fins, improved heat shielding, and a refined fuel-transfer system to raise payload performance and enable higher flight rates toward missions such as Starlink deployments, NASA Artemis landings, and future crewed Mars flights.
