Elon Musk’s latest Starship launch was postponed at the eleventh hour on Sunday. The latest in a growing list of SpaceX failures was to be the model’s 10th mission, and it was fully fueled ahead of a launch time of 7:35 p.

SpaceX postponed the launch of its Starship rocket for the second time in two days, after bad weather forced a last-minute halt on Monday. The rocket was scheduled to lift off from the company’s Starbase facility in southern Texas at 7.

Musk made the announcement in a post on X, saying, “Starship launches again next month.” Additional details about a specific date have yet to be shared by Musk or SpaceX, but multiple reports over recent weeks have suggested that the 10th flight of the world’s most powerful rocket could take place in the first half of the month.
