Following a successful Starship Flight 10, SpaceX is ramping up preparations for Starship Flight 11. Just ten days post-Flight 10, the company has transported the Super Heavy booster to the launch pad, gearing up for an anticipated static fire test. Although the performance of the Flight 10 booster was largely nominal, it did experience an engine out during liftoff and encountered issues with the grid fins as it neared its splashdown point. SpaceX has yet to release a comprehensive update on the outcome of Flight 10, and depending on the pace of pre-flight testing, Flight 11 might take to the skies as early as October.
Accelerating Starship Testing to Leverage Flight 10’s Achievements
It’s anticipated that Starship Flight 11 will mark the final launch for SpaceX’s current generation of boosters and spacecraft. While the boosters have demonstrated reliable performance across multiple tests, the upper-stage ships have had notable inconsistencies. Flight 10 represented a leap forward, successfully accomplishing a gentle splashdown in the Indian Ocean.
Following the significant advances made during Flight 10, SpaceX appears eager to expedite the next flight. Available footage from local media confirms that they have moved the Flight 11 booster to the launch pad for a static fire test.
The static fire test for Starship Flight 11 could occur imminently, possibly as soon as tomorrow. This upcoming test will see SpaceX reusing a booster for the second time, following the reuse of a booster from Flight 7. For Flight 11, they will utilize the booster that previously flew on Flight 8.

However, the previous flights—7, 8, and 9—suffered from significant issues, failing to achieve a suborbital trajectory or successful re-entry into the Earth’s atmosphere. In Flight 7, vibrations led to a propellant leak that caused an early engine cutoff. Flight 8 faced an even more dramatic fate when an engine failure resulted in the rocket spinning out of control.
SpaceX later confirmed that the debris from the failed launches fell within predetermined safety zones, minimizing risk to life and property below.
Following Flight 7, SpaceX harbored ambitious aspirations for its second-generation ship, including deploying Starlink simulator satellites, reigniting a Raptor engine in space, and testing new heat shield tiles. Unfortunately, these aspirations were thwarted as the ship could not achieve suborbital flight in the preceding two tests.

Starship Flight 9 did achieve some progress by entering a suborbital trajectory; however, the lack of subsequent atmospheric re-entry precluded SpaceX from testing the heat shield, deploying the Starlink simulators, or reigniting the Raptor engine in space.
In stark contrast, Starship Flight 10 proved to be a definitive success. The spacecraft effectively separated from the booster, deployed the Starlink simulators, and successfully reignited the Raptor engine. Following a breathtaking visual display during re-entry, Starship concluded its mission with a successful splashdown in the Indian Ocean.
This mission marked the first successful atmospheric entry for the ship, resulting in its heat shield tiles being coated with distinctive orange and white residue upon splashdown. Elon Musk later stated that this residue from the splashdown was attributed to specific metallic tiles and areas where tiles had been omitted for material evaluation purposes.

Given that Flight 11 is likely the concluding flight for this generation of boosters and rockets, it positions SpaceX to advance to its third-generation Starships in Flight 12. Although it remains uncertain whether Flight 12 will occur in 2025, local media have captured footage showing that the construction of the rockets is already underway.
Recent reports indicate that the forward section of SpaceX’s third-generation Super Heavy booster is complete. This upper section incorporates the interstage, integral for diverting thrust away from the booster’s internals during stage separations.
This redesigned interstage represents a crucial enhancement for the third-generation rockets, as emphasized by Musk in earlier presentations. He noted that the new design would significantly improve thrust diversion efficiency.
With recent testing of the Starship program, SpaceX has begun focusing on optimizing efficiency. To enhance the performance of the Super Heavy booster, SpaceX restricted certain interstage vents during Flight 9 to reduce fuel consumption and extend its range.
Furthermore, previous flights showcased the booster operating at a steeper angle of attack, which increased aerodynamic drag and minimized fuel usage for deceleration prior to splashdown.
Additionally, the third-generation Starship rockets will feature revamped grid fins, a signature component of SpaceX’s rocket design. The new fins are larger and specifically crafted for managing a higher angle of attack, thereby enhancing control during flight. Notably, the positioning of these fins has been adjusted to situate their internal components inside the tank, optimizing the booster’s design.
