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.

Starship has faced a series of setbacks in its development phase, including multiple fiery explosions.
Flights 7, 8 and 9 ended in failure after liftoff earlier this year, and another rocket exploded on a test stand in June.
Initially, SpaceX appeared hopeful in the run-up to Monday's test flight and shared a post on X.
"Counting down to Starship's tenth flight test. Weather is currently 55% favorable for launch at the start of the window," the post read.
Despite the failings, SpaceX has pressed on and said each setback is part of the learning curve for the world’s most powerful, 403-foot rocket.

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.
