SpaceX plans to launch its new Starship mega-rocket to orbit on Thursday, after a frozen valve stopped the first attempt.
If Starship succeeds, it'll be the tallest, most powerful, and only fully reusable rocket to ever fly.
SpaceX plans to attempt the launch and see what happens on Thursday, during a launch window from 8:28 a.m. to 9:30 a.m. Central Time.
SpaceX founder and CEO Elon Musk, who estimates a 50-50 chance of success on Starship's first orbital launch.
