STARBASE, Texas — SpaceX scrubbed the 10th test flight of its Starship rocket on Sunday night, delaying the launch just minutes before scheduled liftoff to address a critical ground systems issue, the company said.
The countdown was halted approximately 30 minutes before the estimated launch time. According to Reuters, the 232-foot Super Heavy booster and attached 171-foot Starship upper stage were already fueled when the decision was made.
The flight was intended to test critical upgrades, including enhanced thrust, revamped heat-shield tiles, and more robust steering flaps — all key to improving Starship’s reusability and future missions. The booster would have aimed for a splashdown in the Gulf of Mexico, while Starship itself would attempt engine burns in space, deploy Starlink simulators, and reenter over the Indian Ocean.
This latest postponement follows a string of setbacks this year: multiple flight terminations, motor failures, and a high-profile ground test explosion in June. Despite these challenges, SpaceX continues to pursue an aggressive launch cadence to support NASA’s Artemis III mission, which targets a crewed moon landing by 2027.
Industry observers note that while the “rapid iterative development” model adopted by SpaceX allows for fast progress, it also means frequent delays and heightened program scrutiny. As the company works toward making Starship fully reusable, each test offers valuable data — whether the launch succeeds or not.
“Each scrub gives SpaceX an opportunity to fine-tune its ground systems and test protocols,” said aerospace analyst Karen Thompson of the Center for Space Policy. “It’s frustrating—but not unexpected—in this phase of rocket development.”
Elon Musk, who had previously planned to livestream the launch, called off that broadcast as well. SpaceX confirmed it will attempt the launch again as early as Monday, Aug. 25.
With commercial and NASA-backed ambitions hinging on full Starship capability, SpaceX’s ability to solve recurring technical issues will be a key watchpoint for investors, partners, and regulators monitoring the world’s most powerful rocket to date.
