A SpaceX Starship's upper stage exploded minutes after launch from Texas on Thursday, and the rocket was declared a "loss" in the seventh test flight of the heavy-lift spacecraft. The mission was unmanned.

SpaceX launched its Starship rocket on its latest test flight Thursday, but the spacecraft was destroyed following a thrilling booster catch back at the pad. Elon Musk’s company said Starship broke apart — what it called a “rapid unscheduled disassembly.

The primary objectives for SpaceX were stress-testing the new ship and avionics, catching the booster at the launchpad for potential reuse, deploying the dummy satellites in space, and a targeted water landing. It wasn't immediately known what caused the redesigned spaceship to fail.
