SpaceX plans to conduct the 10th integrated flight test of its Starship launch system on Sunday, 24 Aug., targeting a 6:30 p.m. CDT liftoff from the company’s Starbase facility in South Texas. Notices to airmen and mariners have been posted, and Chief Executive Officer Elon Musk confirmed the date, marking the vehicle’s first flight attempt since a ground-test explosion halted activities in June. The uncrewed mission—designated IFT-10—pairs Super Heavy booster B15 with upper stage S37 in their first outing as the company rolls out several design changes. Most visible is a switch to three, 50 percent larger grid fins on the 232-foot booster, intended to give stronger control authority and align with the launch tower’s ‘catch’ arms on future flights. SpaceX says it has also reinforced a fuel-tank pressurization diffuser and other upper-stage plumbing that contributed to Starship’s loss on 27 May. If the countdown proceeds, Super Heavy will attempt a water landing in the Gulf of Mexico, while Starship will fire a single Raptor engine in space and release eight Starlink v3 simulator payloads before re-entering. A successful test would advance the fully reusable, 403-foot system that underpins NASA’s lunar landing architecture and Musk’s goal of crewed Mars missions. The flight follows three launch failures and a static-fire accident this year, setbacks that have prompted outside criticism of the vehicle’s architecture and accelerated iteration by SpaceX engineers. Clearing those hurdles on Sunday would restore momentum to a program Musk hopes to fly every three to four weeks and, over time, reshape heavy-lift economics across the global launch market.
