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.

SpaceX confirmed the upper stage had undergone "rapid unscheduled disassembly," the company's euphemism for an explosion.

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. This is amateur video taken on the Turks and Caicos islands that shows debris flying overhead.
