SpaceX made multiple changes in the wake of a January Starship failure, only to suffer a second straight vehicle breakup Thursday.

SpaceX has launched the eighth test flight of its Starship megarocket. The mission is designed to achieve objectives that weren’t met during a previous fiery flight.

Nearly two months after an explosion sent flaming debris raining down on the Turks and Caicos, SpaceX launched another mammoth Starship rocket on Thursday, but lost contact minutes into the test flight as the spacecraft came tumbling down and broke apart.
