Engineers completed a final test of Starship's propulsion system with a so-called "spin prime" test Wednesday at the launch site in South Texas. Ground crews then rolled the ship back to a nearby hangar for engine inspections, touchups to its heat shield, and a handful of other chores to ready it for liftoff.

SpaceX’s Starship, the world’s largest rocket, could soon be launching from Florida’s Space Coast — but those liftoffs may also shut down popular beaches for weeks at a time.
