The seventh test flight of SpaceX’s Starship ended with a successful landing of the rocket’s first stage but also the loss of the Starship vehicle

SpaceX CEO Elon Musk took to X on Thursday night to explain what his company believes may have caused part of the Starship rocket to experience a "rapid unscheduled disassembly."

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.
