SpaceX has blown up another Starship mega rocket on a test flight. Nearly two months since the last explosion, SpaceX launched another 403-foot Starship from Texas on Thursday, but lost contact with the spacecraft within minutes.

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

After SpaceX’s Starship rocket exploded during a test flight in January, the company had hoped its nect launch attempt would go better. But again, controllers lost contact with the upper-stage vehicle.
