Full duration single-engine static fire test of Starship 40

- SpaceX is conducting a single-engine static fire test of Starship 40, the latest prototype of the Starship upper stage (the spacecraft part of the Starship/Super Heavy system). A "static fire" is a ground test where the rocket's engines are ignited while the vehicle remains firmly anchored, allowing engineers to verify engine performance, plumbing, and control systems before an actual launch. "Full duration" means the engines burned for the same length of time they would during a real ascent — a more thorough validation than a brief "burp" test. Starship is SpaceX's fully reusable, next-generation launch system designed to carry crew and cargo to Earth orbit, the Moon, and Mars; it is the largest and most powerful rocket ever built. Testing occurs at SpaceX's Starbase facility in Boca Chica, Texas. This is part of an iterative development campaign where prototypes are built and tested rapidly, often failing in dramatic ways, to refine the final design.
