@SpaceX For context, Booster 21 is the fourth stacked V3 Super Heavy and already ran a 15-second 33-Raptor static fire in August, after which SpaceX swapped one engine.
It is now on its second trip to Pad 2 this month for Flight 14 with Ship 41. 🚀
@SpaceX Booster movement is a quieter milestone than a launch announcement, but it’s the kind of hardware progress that makes Starbase timelines legible
@SpaceX The choreography gets more impressive every time—Starbase is starting to look less like a launch site and more like a machine that happens to launch rockets.
@SpaceX The impressive part isn’t the booster on the pad.
It’s the thousands of decisions, tests, failures, and iterations that made getting it there possible.
Big breakthroughs are built long before they’re visible. 🚀
