SpaceX has initiated engine testing for the thirteenth Starship flight, beginning with a static fire of a single engine on the upper stage at the Starbase facility in Texas. According to an official update from SpaceX on June 26, 2026, the company is moving through its pre-flight testing sequence, with Gwynne Shotwell targeting a launch window in July to refine flight performance and address technical imperfections observed during the previous flight.
How does SpaceX prepare for a new Starship flight?
The preparation process relies on a sequence of tests where engines are ignited while the vehicle remains anchored to the test stand. SpaceX engineers verify performance before moving to other configurations. The recent test involved only one of the six engines installed on the upper stage. These engines are divided into two sets: three central engines, which serve in particular during the return to Earth, and three exterior engines, which are used during maneuvers in the space vacuum. According to the company, this testing is necessary before final assembly of the two segments.
What is the objective of the upcoming Starship mission?
The thirteenth flight is intended to serve as a test to correct technical imperfections observed during the previous flight test. Gwynne Shotwell, the president and COO of SpaceX, noted that the mission profile will remain similar to the prior flight, without notable acrobatics.
How does Starship testing compare to traditional aerospace cycles?
SpaceX employs an iterative development cycle. This approach results in a frequency of engine tests and flight attempts. SpaceX maintains that the data gained from a flight outweighs the cost of the vehicle.
Did you know?
The Starship upper stage is powered by a total of six engines.
Frequently Asked Questions
- When is the next Starship flight? Gwynne Shotwell has indicated a target for July, pending successful completion of current engine and stage testing.
- What is a static fire test? It is a ground test where the rocket’s engines are ignited while the vehicle is held firmly to the launch pad.
- Why does SpaceX test engines one at a time? Testing individual engines allows engineers to verify the health of specific components.
