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's Starship is scheduled for its eighth flight test this week, after plans for a launch Monday—the first launch since the explosive attempt in January—were scrubbed. The spacecraft maker didn't explain why Monday's launch was called off.
