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.

The Federal Aviation Administration said on Friday it cleared the SpaceX Starship vehicle to return to flight operations while an investigation into the January 16 Starship Flight 7 mishap remains open.
