Super Heavy Booster B21 Rolls Out to Pad 2 Ahead of Starship Flight 14

SpaceX rolled Super Heavy booster B21 out to the launch mount at Pad 2, Starbase, shortly before midnight local time on September 20, 2026, reaching the pad roughly two hours later (early September 21 CDT). B21 is one of two vehicles needed for Starship Flight 14, the program's first attempt at reaching full orbital velocity, still targeted for no earlier than September 28 at 7:15am CT pending FAA orbital license approval. As of Monday morning no road closures had been published for the City of Starbase, suggesting Starship upper stage S41 was likely still a day or two from its own rollout to join B21 on the pad.
