SpaceX Reveals Reasons For The Starship Delay! When Is Flight 12?
The video explains why SpaceX’s Starship Flight 12 has slipped and outlines the current production and testing status of the Starship fleet. At Pad 2, crews are performing full‑system cryogenic flow checks, including a frosty SQD arm test, and have replaced a faulty vaporizer. SpaceX treats each launch attempt as a wet‑dress rehearsal, stacking the vehicle, loading propellant and running the countdown, which differs from NASA’s separate rehearsals. Meanwhile, Mega Bay 2 houses three Starships—Ship 39 ready for Flight 12, Ship 40 prepared for cryo testing, and Ship 41 just beginning stacking—showing a true production line. The presenter notes that Booster 19 suffered engine damage during a rapid shutdown of a 10‑engine static fire, and a 33‑engine test aborted at T+1.88 seconds due to a sensor issue, raising questions about potential hidden damage. SpaceX also filed an FCC authorization for Flight 13 starting May 29, indicating a tight launch cadence, and announced a new parts‑manufacturing site in Maryland to tap East‑Coast talent. These developments suggest SpaceX is moving from a test program to an operational cadence, potentially compressing the gap between Flights 12 and 13 to weeks rather than months. Faster turnaround could accelerate commercial payload deliveries and increase pressure on competitors, while the talent‑focused expansion mitigates the remote‑site hiring challenge.
