Elon Musk's SpaceX's Starship test flight ended in failure as the spacecraft exploded and broke apart, following a suspected fuel leak in the engine firewall.

The Federal Aviation Administration has paused SpaceX's the launch of its Starship rocket as the U.S. agency oversees an investigation by the private company of the breakup after a test launch Thursday.

SpaceX pulled off its “chopsticks” catch of a Super Heavy rocket booster but lost the Starship spacecraft on Thursday during the vehicle’s seventh uncrewed test flight.
