Failure to Launch; SpaceX rocket launch postponed due to inclement weather
Just 30 seconds before liftoff yesterday, SpaceX grounded a Falcon 9 rocket launch at the Kennedy Space Center in Florida. Falcon 9 completed all of its pre-launch sequencings, including loading liquid oxygen, before the launch’s cancellation. Mere seconds were left before the engine controller would have commanded the rocket’s engine ignition sequence to begin.
