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.

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 seventh fully-stacked SpaceX Starship lifted off on time from Starbase, Texas, but eight-and-a-half minutes into flight, things started to go wrong. While the first-stage Super Heavy booster returned to the launch pad for the second time, SpaceX ultimately lost this Starship.
