SpaceX has delayed the highly anticipated tenth test flight of its Starship rocket for the second straight day, standing down from a planned launch on August 25, due to adverse weather conditions at its Starbase launch site in South Texas. The company announced the scrub late Monday evening, attributing the decision to anvil clouds posing a lightning risk, and is now assessing the next viable opportunity to fly, which could come as soon as today at 6:30 p.m. CT (local). Boca Chica Beach and road closures around the Starbase site are scheduled for August 26, suggesting a potential attempt as early as Tuesday evening, weather permitting [all dates are subject to change].

Cosmic Chronicles journalists are in South Texas eager to watch Starship Flight 10 liftoff! They have shared views of the Starbase launch site on social media, shown below. They are able to do this thanks to readers like you!

The latest postponement follows a similar setback on August 24, when SpaceX called off the launch attempt shortly before the scheduled window due to an issue with ground systems, later identified by SpaceX founder Elon Musk as a liquid oxygen leak on the ground side. Musk indicated the team aimed to resolve the problem and attempt liftoff the following day, but weather intervened. Weather conditions were reported as only 55% favorable at the start of the August 25 window, which contributed to the decision to stand down.

SpaceX had rolled out the Starship vehicle—comprising the Super Heavy booster and upper-stage Starship spacecraft—to the pad on August 23, targeting a 60-minute launch window opening at 6:30 p.m. CT on August 24. 14 The test flight, originally eyed for no earlier than late June 2025, had already faced earlier delays, including a significant setback in June when Ship 36 exploded during propellant loading for a static fire test. These interruptions come amid a series of incremental improvements in the Starship program, with the ninth flight in May 2025 achieving engine cutoff but suffering from leaks that led to pressure loss during coast and re-entry phases. Issues that the company has fixed by introducing upgrades to the launch system that will be put to the test during the upcoming Flight 10.

Starship, the world’s most powerful rocket, is central to SpaceX’s ambitions for reusable space travel, including crewed missions to Mars and supporting NASA’s Artemis program for lunar landings. Delays in Starship’s development have ripple effects, with NASA’s Artemis III mission—intended to use a Starship variant as a lunar lander—now likely pushed to 2028 or beyond. The company announced this week that the Italian Space Agency signed an agreement for a future Starship mission to Mars.

Despite the setbacks, Musk has emphasized faster launch cadences for upcoming tests, aiming for one every three to four weeks following earlier flights. The rapid pace of testing will enable the company to speed up the rocket-ship’s development.

SpaceX plans to livestream the next Flight 10 attempt on its website and X account, with updates expected as weather conditions improve. The company has conducted nine previous Starship test flights since 2023, each building on lessons from explosions, partial successes, and data collection to refine the vehicle’s performance.
