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.

The U.S Federal Aviation Administration (FAA) has closed its investigation into SpaceX's Starship mission failure this spring and given the green light for Starship Flight Test 10 to proceed this weekend.
