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.

SpaceX officials said they conducted an "extended duration static fire" with the Starship they intend to use for its eighth test flight. They said they used multiple engine thrust levels and hardware configurations to recreate the vibration levels from the failed flight.
