SpaceX Scraps Starship Launch, Eyes Friday for 12th Test Flight

SpaceX scrubbed the launch of its massive Starship rocket Thursday evening, and will try again for its 12th test flight on Friday.

A 90-minute launch window opened at 6:30 p.m. ET, on Thursday. During a livestream of the event, SpaceX video hosts said the company "got the vehicle totally loaded" onto a new launch pad.

The rescheduled launch will represent the debut of Starship V3, which "is designed to deliver 100 metric tons to Earth's orbit in a fully reusable configuration while enabling rapid turnaround times akin to commercial aviation," SpaceX said in its IPO prospectus on Wednesday.

Elon Musk's reusable rocket maker has spent more than $15 billion on its Starship program, according to Wednesday's filing. The company says Starship is key to launching more satellites into orbit to build out its Starlink constellation at a faster pace than it's been able to using Falcon 9 rockets. Starlink delivers wireless internet services to consumers, businesses and government agencies.

The latest version of the Starship rocket is slated to launch from a newly designed pad at SpaceX's facility in Starbase, Texas, an official company town previously known as Boca Chica.

The test flight likely marks the company's last chance to dazzle investors with a Starship launch before shares hit the public market. Last year, SpaceX's space segment generated revenue of $4.1 billion and recorded an operating loss of $657 million.

The company counts on Starlink for a hefty amount of revenue and all of its profits. The connectivity unit, which consists mostly of Starlink, brought in sales of $11.4 billion and operating income of $4.4 billion in 2025. That accounted for 61% of the company's total sales last year, and 69% in the first quarter.

About its space business, SpaceX said in its prospectus that its "growth strategy depends on our ability to increase our launch cadence and payload capacity, which is dependent on the successful development of Starship at scale."

Musk has long held the grandiose goal of colonizing Mars, using the Starship rocket to lift cargo and as many as 100 people at a time into orbit.

NASA is also betting that Starship will serve as the lander to carry its astronauts to the moon on its Artemis IV mission, currently scheduled for early 2028. The mission would mark U.S. astronauts' first trip back to the moon in more than half a century.

Starship V3 stands 408 feet tall when fully stacked, and features new engines that should make it a stronger rocket, with 18 million pounds of thrust. The company is carrying mock Starlink satellites during the test flight but no astronauts or other cargo.
