After back-to-back Starship upper stage failures, SpaceX on Tuesday again launched the world's most powerful rocket, but faced new problems.

Federal regulators gave SpaceX the green light for another test flight of Starship, the most powerful launch vehicle ever constructed, after mishaps earlier this year rained debris near populated islands.

The debris fell into the Indian Ocean away from inhabited areas. SpaceX was unable to conduct several tests it had planned during the flight, such as deploying simulators of the next-generation Starlink satellites and assessing improvements to the heat shield tiles.
