SpaceX, Elon Musk’s space exploration company, has scheduled the 11th test flight of the Starship mega-rocket for this Monday, October 13, 2025. The launch, which is crucial for the development of the fully reusable system, is set to take place at Starbase in South Texas, United States. This test follows the partial success of the 10th flight in August, where all primary objectives were met, but the controlled return of the ship did not materialize.
The launch window for the lift-off of the stack, which comprises the Super Heavy booster and the Starship upper stage, opens at 6:15 p.m. Central Time (7:15 p.m. EDT). The mission follows a similar suborbital flight profile to previous attempts but incorporates new and stringent engineering tests to gather critical data. Expectations are high, as Starship is the foundation of NASA’s Artemis program, which aims to return astronauts to the lunar surface.
Starship to test unprecedented dynamic banking maneuver
The 11th flight focuses on refining the most sensitive phases of the mission, especially atmospheric reentry and the return of the stages. The most powerful rocket ever built will execute complex maneuvers simulating a return to the launch site.
The ship will perform an unprecedented dynamic banking maneuver and test new subsonic guidance algorithms.The goal is to mimic the trajectory of future flights that will return to Starbase.
Raptor engine relight in space vacuum
One of the most significant objectives of this mission is the demonstration of a Raptor engine relight in a vacuum, a critical step for future in-space operations. The procedure aims to validate Starship’s ability to adjust its trajectory in orbit, which is essential for long-duration missions.
The relight test of a single Raptor engine in space is an engineering milestone that ensures greater redundancy and safety for the spacecraft.
This capability will be vital for in-orbit refueling, a necessary strategy to enable interplanetary travel, including the ambitious crewed missions to Mars.
The demonstration of deploying Starlink satellite simulators is also part of the Flight 11 agenda, showcasing Starship’s capability as a payload launcher.
Focus on safety and the reusable B15 booster
SpaceX has implemented hardware and operational corrections, including the removal of heat shield tiles in areas deemed vulnerable. This measure is intended to stress-test the limits of Starship’s thermal protection during the intense atmospheric reentry.
The Super Heavy booster used on this flight, known as B15, previously flew on the eighth test earlier in 2025, reinforcing the company’s reusability strategy.
- Booster B15 features 24 Raptor engines that have proven their reliability in previous flights.
- The final plan for this test phase involves Starship’s splashdown in the Indian Ocean, repeating the safety strategy adopted in recent launches.
- Super Heavy, in turn, will attempt a controlled landing burn over the Gulf of Mexico, but will not be recovered on this mission.
Full and rapid reusability, which includes in-orbit refueling by tanker vehicles, is the core of the company’s vision for lowering costs and accelerating space exploration. The data collected from the 11th flight will be decisive in advancing Starship’s design toward the V3 version, focusing on cargo capacity and safety.
