Starship’s tenth flight test lifted off on August 26, 2025, at 6:30 p.m. CT from Starbase, Texas, taking a significant step forward in developing the world’s first fully reusable launch vehicle.The results were a significant step forward as every major objective was met, providing critical data to inform designs of the next generation Starship and Super Heavy.
The flight test began with Super Heavy successfully lifting off by igniting all 33 Raptor engines and ascending over the Gulf of America. Successful ascent was followed by a hot-staging maneuver, with Starship’s upper stage igniting its six Raptor engines to separate from Super Heavy and continue the flight to space.
Following stage separation, the Super Heavy booster completed its boostback burn to put it on a course to a pre-planned splashdown zone. The booster descended and successfully initiated its landing burn, intentionally disabling one of its three center engines during the final phases of the burn and using a backup engine from the middle ring. Super Heavy entered into a final hover above the water before shutting down its engines and splashing down into the water.
Starship completed a full-duration ascent burn and achieved its planned velocity, successfully putting it on a suborbital trajectory. The first in-space objective was then completed, with eight Starlink simulators deployed in the first successful payload demonstration from Starship. The vehicle then completed the second ever in-space relight of a Raptor engine, demonstrating a key capability for future deorbit burns.
Moving into the critical reentry phase, Starship was able to gather data on the performance of its heatshield and structure as it was intentionally stressed to push the envelope on vehicle capabilities. Using its four flaps for control, the spacecraft arrived at its splashdown point in the Indian Ocean, successfully executed a landing flip, and completed the flight test with a landing burn and soft splashdown.
Over the course of a flight test campaign, success will continue to be measured by what we are able to learn, and Starship’s tenth flight test provided valuable data by stressing the limits of vehicle capabilities and providing maximum excitement along the way.
SpaceX plans for Tuesday launch of Starship’s tenth Flight Test
The tenth flight test of Starship is preparing to launch as soon as Tuesday, August 26. The launch window will open at 6:30 p.m. CT.
“Ground side liquid oxygen leak needs to be fixed. Aiming for another launch attempt tomorrow,” CEO Elon Musk posted on the social media platform X.
After completing the investigations into the loss of Starship on its ninth flight test and the Ship 36 static fire anomaly, hardware and operational changes have been made to increase reliability. You can read the full technical summary of the investigations here.
The upcoming flight will continue to expand the operating envelope on the Super Heavy booster, with multiple landing burn tests planned. It will also target similar objectives as previous missions, including Starship’s first payload deployment and multiple reentry experiments geared towards returning the upper stage to the launch site for catch.
The booster on this flight test is attempting several flight experiments to gather real-world performance data on future flight profiles and off-nominal scenarios. The Super Heavy booster will attempt these experiments while on a trajectory to an offshore landing point in the Gulf of America and will not return to the launch site for catch.
Following stage separation, the booster will flip in a controlled direction before initiating its boostback burn. This maneuver was demonstrated for the first time on Flight 9 and requires less propellant to be held in reserve, enabling the use of more propellant during ascent to enable additional payload mass to orbit.
The primary test objectives for the booster will be focused on its landing burn and will use unique engine configurations. One of the three center engines used for the final phase of landing will be intentionally disabled to gather data on the ability for a backup engine from the middle ring to complete a landing burn. The booster will then transition to only two center engines for the end of the landing burn, entering a full hover while still above the ocean surface, followed by shutdown and drop into the Gulf of America.
The Starship upper stage will again target multiple in-space objectives, including the deployment of eight Starlink simulators, similar in size to next-generation Starlink satellites. The Starlink simulators will be on the same suborbital trajectory as Starship and are expected to demise upon entry. A relight of a single Raptor engine while in space is also planned.
The flight test includes several experiments focused on enabling Starship’s upper stage to return to the launch site. A significant number of tiles have been removed from Starship to stress-test vulnerable areas across the vehicle during reentry. Multiple metallic tile options, including one with active cooling, will test alternative materials for protecting Starship during reentry. On the sides of the vehicle, functional catch fittings are installed and will test the fittings’ thermal and structural performance, along with a section of the tile line receiving a smoothed and tapered edge to address hot spots observed during reentry on Starship’s sixth flight test. Starship’s reentry profile is designed to intentionally stress the structural limits of the upper stage’s rear flaps while at the point of maximum entry dynamic pressure.
Flight tests continue to provide valuable learnings to inform the design of the next generation Starship and Super Heavy vehicles. With production ramping up inside Starfactory at Starbase alongside new launch and test infrastructure actively being built in Texas and Florida, Starship is poised to continue iterating towards a rapidly and fully reusable launch system.
SpaceX scrubs Starship Flight 10 at 30 minutes before liftoff to troubleshoot ground systems
While the weather was not good the cause of the delay of the the tenth flight test of Starship was as SpaceX explains, “to allow time to troubleshoot an issue with ground systems.” SpaceX is now preparing to launch as soon as Monday, August 25. The launch window will open at 6:30 p.m. CT.
A live webcast of the flight test will begin about 30 minutes before liftoff, which you can watch on X @SpaceX. You can also watch the webcast on the X TV app. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to check in here and stay tuned to our X account for updates.
