SpaceX fired all 33 Raptor engines on Booster 22 ahead of Starship Flight 15. The test advances preparations for a November launch and a planned dual recovery.SpaceX confirmed the test in a post on social media, describing it as a full-duration firing of all 33 engines.

SpaceX has completed a major engine test of its Super Heavy rocket booster and Starship as it prepares for the 15th integrated flight test of Starship Super Heavy, with the company targeting a launch in November.The Elon Musk-led company fired all 33 Raptor engines on the Super Heavy booster assigned to the mission in a full-duration static-fire test at its Starbase facility in South Texas on October 25.The test lasted approximately 15-16 seconds, marking a key milestone in preparations for the next flight of the world's largest rocket system.Starship Flight 15: Ship 42 conducts a six-engine static fire test. https://t.co/Ug0QFxQ7JC https://t.co/94NO3pZ4Lu— NSF - NASASpaceflight.com (@NASASpaceflight) October 27, 2026SpaceX confirmed the test in a post on social media, describing it as a full-duration firing of all 33 engines on the booster preparing for Flight 15. The booster, identified as Booster 22, is expected to fly alongside Starship's upper stage, Ship 42.The successful test clears an important step for the first-stage booster, although the upper-stage spacecraft still needs to complete its own engine firing and final checks before the two vehicles are ready for launch.A CRUCIAL TEST AHEAD OF FLIGHT 15 A static-fire test involves igniting a rocket's engines while the vehicle remains secured to the launch mount.

It allows engineers to evaluate engine performance and vehicle systems under operating conditions without launching the rocket.Super Heavy forms the first stage of the Starship launch system, powering the vehicle through the initial phase of ascent before separating from the upper stage.Full duration 33-engine static fire for the Super Heavy booster preparing for Flight 15 https://t.co/7eqbC4h0Fh— SpaceX (@SpaceX) October 25, 2026The booster is designed to return to the launch site, where SpaceX aims to catch it using mechanical arms attached to its launch tower.Flight 15 is expected to push the company's reusability ambitions further.SpaceX plans to attempt the recovery of both the Super Heavy booster and the Starship upper stage, a milestone that would mark a major advance towards making the entire launch system reusable.The company has previously caught returning Super Heavy boosters using the tower's mechanical arms. However, it has yet to recover a Starship upper stage at the launch site.- Ends
