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.

A Falcon 9 rocket carrying 27 Starlink craft is scheduled to lift off from California's Vandenberg Space Force Base today, during a nearly two-hour window that opens at 12:03 p.m. EST (1703 GMT; 9:03 a.m. local time). SpaceX will webcast the action live via its X account, beginning about five minutes before launch.
