SpaceX Booster 20 fires all 33 Raptor 3 engines for record 24-second static fire ahead of Starship Flight 13
Starship Flight 13 just cleared its final ground test: SpaceX fired all 33 Raptor 3 engines on Super Heavy Booster 20 for a record 24 seconds at Starbase. A full-duration 33-engine burn is what a real launch demands. Per NASASpaceflight, the launch window opens as early as July 1
SpaceX has cleared the last major ground test before Starship Flight 13. On Thursday the company ignited all 33 Raptor 3 engines on Super Heavy Booster 20 at its Starbase facility in Texas and held the burn for a record 24 seconds, the longest static fire a Super Heavy booster has performed, as reported by NASASpaceflight. The duration matters more than the spectacle. A full-duration static fire across all 33 engines simultaneously tests the exact configuration a real launch requires: sustained ignition, vibration and propellant flow through the entire engine section at once. Booster 20 belongs to the upgraded V3 generation of Super Heavy, and this test was the last item standing between the booster and its assignment on Flight 13. With the ground campaign complete, attention shifts to the launch itself. Space.com and NASASpaceflight report that the Flight 13 window opens as early as July 15. Each Starship test flight carries weight beyond SpaceX: the vehicle is contracted by NASA to land Artemis astronauts on the Moon, so every booster milestone feeds directly into that program's timeline.
