Federal regulators gave SpaceX the green light for another test flight of Starship, the most powerful launch vehicle ever constructed, after mishaps earlier this year rained debris near populated islands.

Facing a significant increase in the number of SpaceX launches, British officials detailed their concerns about the safety of Turks and Caicos and other Caribbean territories after debris from an earlier failed launch littered beaches and roads.

SpaceX is set Tuesday for the next test flight of its Starship megarocket—the linchpin of founder Elon Musk's Mars ambitions—after the vessel's last two outings ended in fiery explosions.
