SpaceX’s Starship’s second shot at a 10th test flight Monday was aborted after weather conditions forced the company to halt liftoff from its South Texas site.

Monday evening’s test was a crucial milestone for Elon Musk’s ambitious plans to use Starship to bring astronauts to the moon and, eventually, conquer Mars.

But in a post shared on X, SpaceX said, “Standing down from today’s flight test attempt due to weather. Starship team is determining the next best available opportunity to fly.”

On Sunday, SpaceX had said that first attempt was scrapped because of ground-system problems with the team resetting its sights on a new launch window at 7:30 p.m. ET Monday. 

The focus of Monday’s mission was on the spacecraft’s upper stage, designed to carry crew and cargo into space before returning to Earth with a controlled descent into the Gulf of America.

A successful test would mark a step forward in proving the system’s reusability, which is key to Musk’s vision of affordable space travel.

Fox News Digital has reached out to SpaceX for comment.
