The FAA has grounded SpaceX's Starship pending an investigation into why the rocket's upper stage dramatically disintegrated in its latest flight.

SpaceX’s Starship rocket exploded just minutes into its seventh test flight, an unexpected setback after the Elon Musk-led company had made steady progress advancing the vehicle’s capabilities.

SpaceX, the private space technology company owned by Elon Musk, is asking federal authorities to approve a new round of tests for a prototype reusable rocket, but some of them may never make it back to the surface intact and will crash in the ocean.
