SpaceX sent out a notice on Tuesday about the potential for sonic booms during the Falcon Heavy launch on Wednesday evening.
The Falcon Heavy, which is made up of three normal-size rockets bolted together. SpaceX is targeting liftoff at 8 p.m. on Wednesday. The launch window closes at 8:32 p.m.
Two of those three rockets will fly back to the Cape together for landing, and that’s when the sonic booms could hit, which would be about eight minutes after liftoff.
SpaceX says the booms could potentially be heard in Brevard, Orange, Seminole and Volusia counties.
It will be Falcon Heavy’s second flight ever and the first commercial launch for monster rocket. It’s been over a year since SpaceX sent Elon Musk’s Tesla Roadster to space.
SpaceX tweeted on April 7 that “Falcon Heavy’s 27 Merlin engines generate more than 5 million pounds of thrust at liftoff, making it the world’s most powerful operational rocket by a factor of two.”
