SpaceX Starship Flight 15: Launch date, objectives, and what to expect

SpaceX is targeting November 2026 for the 15th integrated flight test of its Starship rocket, with the mission expected to attempt a major milestone: catching the spacecraft’s upper stage at its launch tower after returning from space.

The company is also preparing to recover the Super Heavy booster, potentially bringing both stages of its massive launch system back to the launch site.

As of October 28, SpaceX has not announced an official launch date. However, preparations are progressing at Starbase in South Texas, where the company is testing the vehicles assigned to the mission.

The flight will build on September’s Flight 14, which reached orbit and deployed 26 next-generation Starlink V3 satellites.

When is Starship Flight 15 launching?

SpaceX is currently targeting November, although the launch date will depend on testing, vehicle readiness, and regulatory approval.

On October 25, the company conducted a full-duration static-fire test of Super Heavy Booster 22, igniting all 33 Raptor engines for about 15 seconds. The test allows engineers to assess engine and vehicle systems while the booster remains secured to the ground.

According to Space.com, the booster will fly with Starship upper stage Ship 42. The spacecraft has completed its own engine test and is undergoing final systems checks ahead of the launch.

The Federal Aviation Administration’s launch authorization is another factor. SpaceX President and Chief Operating Officer Gwynne Shotwell said during an October earnings call that the company expected its license for Flight 15 to cover return-to-launch-site operations and tower catches for both stages, as reported by Ars Technica.

Attempting to catch both rocket stages

The primary objective is to demonstrate the recovery of both components of the Starship launch system. After liftoff, Super Heavy provides the initial thrust needed to propel Starship toward orbit before separating from the upper stage. SpaceX plans to guide the booster back to Starbase, where mechanical arms mounted on the launch tower, nicknamed “chopsticks,” will attempt to catch it.

SpaceX has already demonstrated booster catches on earlier flights. Flight 15, however, is expected to use the upgraded Booster 22 and attempt the recover both stages in the same mission.

The more ambitious objective is to catch Ship 42 after its orbital flight. Starship will need to reenter the atmosphere, withstand intense heating, and maneuver toward the launch tower for a controlled capture. The spacecraft has previously performed controlled ocean splashdowns, but a tower catch would be a significant step toward making the entire system reusable.

Recovering both stages could eventually reduce refurbishment requirements and the cost of launching payloads. However, a successful catch alone would not prove that Starship can be rapidly inspected, refurbished, and reflown.

Building toward lunar missions

Flight 15 also follows a significant milestone from the previous mission. On September 28, Flight 14 reached orbit and deployed 26 Starlink V3 satellites, demonstrating Starship’s ability to carry operational payloads. However, a Raptor engine shut down prematurely during ascent, shortening the planned mission.

SpaceX has not officially confirmed Flight 15’s payload, though it has discussed another Starlink deployment as a possibility. The program also has implications for NASA’s Artemis lunar exploration campaign.

SpaceX is developing a modified Starship upper stage to serve as a lunar lander, but the vehicle must demonstrate additional capabilities before it can transport astronauts to the Moon. These include in-space propellant transfer, which SpaceX plans to pursue in a future test.

The immediate priority for Flight 15 is to demonstrate that Starship can return both stages to the launch site. Success would advance SpaceX’s reusability ambitions and provide data for subsequent tests as the company works toward a more operational launch system.
