SpaceX says the 10th integrated test flight of its Super Heavy Starship launch vehicle could launch as soon as Aug. 24.
Liftoff from the company’s Starbase, Texas, manufacturing and test site is expected during a launch window that begins at 7:30 p.m. EDT (2330 GMT). SpaceX announced the launch date on X Friday (Aug. 15), about one week later than SpaceX CEO Elon Musk predicted in mid-July when he estimated Starship would launch again in “about three weeks.”
Flight 10 will be Starship’s fourth launch of 2025, and comes at a critical junction in the spacecraft’s development. Starship’s three previously flights this year have ended with the loss of the upper stage, and with each loss comes a tighter squeeze on the timeline to ready the vehicle to serve as the lunar lander for the astronauts on NASA’s Artemis 3 mission to the surface of the moon, slated for sometime in 2027.
The fully stacked, the Super Heavy booster and the Starship upper stage stand about 394 feet (120 meters) tall. Flight 10 will fly Booster 16 and Ship 37, both Block 2 variants of the evolving launch vehicle, as SpaceX introduces incremental upgrades for each mission.
The launch follows Flight 9, which lifted off May 27 and ended with the Ship upper stage breaking apart in space about 45 minutes into flight. Less than a month later, on June 18, a static test fire at Starbase resulted in an explosion, destroying Ship 36 — the vehicle original slated for Flight 10 — and damaging SpaceX test infrastructure.
Those mishap investigations completed, Starship Flight 10 is headed to the launchpad with a fresh set of mission objectives. Once in space, after stage separation, Starship will deploy eight Starlink satellite mass simulators, perform an in-space Raptor engine relight and attempt a controlled splashdown in the Indian Ocean. Booster 16, meanwhile, will alter its trajectory for a controlled splashdown in the Gulf of Mexico.

Of the nine Starship test flights so far, several have achieved partial success — including catching a Super Heavy booster using the launch tower “Mechazilla” chopstick arms and refurbishing it for reuse — but not have yet met all mission objectives from launch to landing.
