For this first flight test, SpaceX said Starship will not attempt a vertical landing of Starship or a catch of the booster.
If successful, Starship and its rocket, which is called Super Heavy, will head up to the skies and 33 Raptor engines will ignite simultaneously. About eight minutes after liftoff, Super Heavy will splash down in the Gulf of Mexico.
Meanwhile, the spacecraft will travel about 150 miles — partially around the Earth — and then splash down in the Pacific Ocean near Hawaii about 90 minutes after liftoff.
There will be a 62-minute window opening at 9:28 a.m. ET. A live webcast began 45 minutes before liftoff.
