Video and on-screen telemetry showed engine ignition starting about three seconds before the planned liftoff, but some engines failed to light and the automated system aborted the launch. The Super Heavy booster carries 33 Raptor engines and the upper stage was carrying 20 Starlink satellites intended to test communications and photograph the heat shield.","Although engineers have conducted recent full-engine tests, Flight 12 revealed that five of the booster’s 33 engines failed to relight during a boostback burn, which prompted software and hardware updates. SpaceX says it has modified the startup sequence and made hardware fixes; Elon Musk posted 'Next launch attempt hopefully in a few days.' Teams are offloading propellant and will inspect and possibly replace engines before scheduling another attempt. Neither stage was meant to be recovered and both would have ended up in the sea. Teams will investigate the issue before another attempt."],"wordCount":171,"readTime":2},"vocabulary":[{"word":"ignite","example":"The engines began to ignite before liftoff.","phonetic":"/ɪɡˈnaɪt/","definition":"to start burning or to start a rocket engine"},{"word":"abort","example":"Controllers had to abort the launch.","phonetic":"/əˈbɔːrt/","definition":"to stop a mission or action before it begins or finishes"},{"word":"propellant","example":"They began to drain the propellant from the tanks.","phonetic":"/prəˈpɛl.ənt/","definition":"fuel used to push a rocket into space"},{"word":"telemetry","example":"Telemetry showed engine performance during the start sequence.","phonetic":"/təˈlɛm.ə.tri/","definition":"data sent from a vehicle to engineers on the ground"}],"quiz":[{"answer":"13th integrated test","question":"What flight number was this Starship test?"},{"answer":"20 Starlink satellites","question":"How many Starlink satellites was the upper stage carrying?"},{"answer":"five of the booster’s 33 engines failed to relight","question":"How many engines failed to relight on Flight 12?"}],"discussion":[{"question":"Do you worry about mechanical failure when you travel by car, train, or plane?
