GoKawiilA SpaceX Starship spacecraft rolls out toward its launch pad past the Starbase Manufacturing Facility before its 10th test flight from the company's complex in Starbase, Texas, U.S., August 23, 2025.
SpaceX's stock fell further on Friday, a day after it aborted a test flight for its Starship rocket at the last second, and amid choppy post-IPO trading.
The aerospace giant was expected to launch its Starship mega rocket within a 90-minute window at 5:45 p.m. in Texas on Thursday, but an engine ignition failure forced SpaceX to scrub the launch.
"Some of the engines didn't start, triggering an automatic launch abort," billionaire founder Elon Musk said in a post on X. "Now offloading propellant. Next launch attempt hopefully in a few days."
SpaceX was last seen down 3.5% in premarket trading, after falling more than 3% in after hours trading.
Musk later added in a post that 2 Raptors will be removed and replaced, and that a launch is planned again for early next week.
Investors are watching the company's rocket tests more closely after it raised a record $85.7 billion in the biggest initial public offering ever in June, pricing shares at $135. SpaceX's shares have soared and dipped since its stock market debut.
