SpaceX plans to launch its Starship megarocket on its next test flight on Monday. The vehicle’s upper stage exploded over the Atlantic Ocean during the last such test.

Federal regulators have closed an investigation into what went wrong when a SpaceX Starship spacecraft — part of the most powerful launch system ever constructed — exploded during a January test flight.

When SpaceX's Starship takes off next time from South Texas, it will have a few touch-ups from the last time the rocket launched in January and rained flaming debris down near the Turks and Caicos Islands.
