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

SpaceX’s colossal Starship rocket suffered a leak, tumbled out of control in space and disintegrated as it hurtled back to Earth during a test flight on Tuesday, in a third setback in a row for the Elon Musk-led company.

Much was riding on Flight 9 for Elon Musk’s giant moon and Mars rocket after debris from January and March flights fell into the Atlantic Ocean, disrupting air travel.

SpaceX's Starship failed its third attempt to put cargo into Earth's orbit, spinning out of control again.

The ninth flight test of SpaceX's Starship megarocket is scheduled for later today, with an hour-long launch window opening at 7:30 p.m. EDT (2330 GMT). A livestream of Starship Flight Test 9 will be available on the Space.com homepage and YouTube channel, as well as on SpaceX's Flight 9 mission page, the @SpaceX X account and X TV app.

Elon Musk will address thousands of SpaceX employees in Texas on Tuesday, May 27. Here's how to watch the talk from home.
