SpaceX rolls Booster 19 to Masseys for cryogenic proof testing after Booster 18 pressure‑test failure

The rollout of Booster 19 shows SpaceX resumed its Starship V3 ground‑test campaign despite the visible detonation during B18's pressure test, preserving momentum in the upgrade program (B18 pressure‑test incident).

Cryogenic proof testing at Masseys validates thermal and propellant systems that determine structural integrity and launch readiness; outcomes will directly affect timing for future integrated Starship flights and the program's launch cadence (recent Falcon 9 flight scrutiny).

This activity occurs alongside ongoing booster milestones across SpaceX's fleet, underlining parallel test and operational workstreams that influence resource allocation and schedule risk for the broader launch manifest (Booster 1100 maiden flight).
