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.

Angry-looking red thunderstorms lit up National Weather Service radar screens along the northern portion of the Cape about 1½ hours before launch.

SpaceX launched its Starship rocket again from Texas after two failed missions. While the rocket flew farther, a door malfunction scrapped the satellite release test.
