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.

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.

SpaceX is poised to launch Flight 8 of its Starship megarocket on Monday (March 3). Here's how to watch the action live.

SpaceX is slated to launch its Starship for the eighth time from Boca Chica, Texas, Friday, though plans could be thwarted if the FAA fails to give the green light.

The test flight will be a repeat of what SpaceX hoped to achieve on the previous Starship launch in January, when the rocket broke apart and showered debris over the Atlantic Ocean and Turks and Caicos Islands.

SpaceX has attained authorization from regulators to fly its massive Starship rocket once again, the FAA announced on Friday.
