SpaceX Stands Down Starship Flight 10, Targets Monday Launch

Boca Chica, Texas, August 25, 2025 - SpaceX postponed its tenth integrated Starship test flight today due to a ground-systems issue, with the company now aiming to lift off Monday evening, August 25, at around 7:30 p.m. EDT.

Shortly before the one-hour launch window opened this evening, SpaceX engineers “stood down from today’s tenth flight of Starship to allow time to troubleshoot an issue with ground systems,” the company announced on its X platform. Elon Musk later clarified that a liquid-oxygen leak in the ground infrastructure needed to be addressed before proceeding with the test.

Starship’s Flight 10 is poised to be the largest rocket launch ever attempted. The fully reusable Super Heavy booster and Starship upper stage stack stands over 400 feet tall and is designed for missions ranging from lunar landings under NASA’s Artemis program to future crewed expeditions to Mars. Monday’s rescheduled attempt will follow the same one-hour window beginning at 7:30 p.m. EDT, weather and technical conditions permitting.

Meanwhile, earlier today SpaceX’s Cargo Dragon spacecraft from the CRS-33 mission successfully docked at the International Space Station, delivering more than 5,000 pounds of science investigations and supplies. The capsule autonomously berthed to the Harmony module at 7:05 a.m. EDT, marking the 33rd commercial resupply flight under NASA’s CRS program.

Despite recent setbacks-including three failed Starship tests this year and an upper-stage explosion in June-SpaceX continues to iterate rapidly on its Starship architecture, adhering to its “fail fast, learn fast” ethos as it pushes toward reusable, heavy-lift launch capabilities.
