SpaceX Starship Booster Static Fire

SpaceX has conducted a static fire test on the super-heavy booster for Starship Flight 11, which comes just two weeks after Flight 10. As a regular practice, the company has shipped this first stage on the launch pad 1 overnight with the transportation vehicle.

Static fire tests are designed to validate the engine configuration and propulsion system in the actual launch environment without leaving the launch pad. The engine ignition remains active for a few seconds before cutting off.

The first stage is essential to kick-start the Starship mission, providing the huge thrust needed to take off from the ground and send it to orbit. It is designed to send the ship into space and perform a hot-staging, firing a boostback burn, and returning to the landing site for a tower catch. This maneuver is important to achieve reusability.

For the past two flights, SpaceX has been conducting tests and experiments on the booster and hasn’t performed the tower catch. These tests have proven important for fuel efficiency, which can be redirected to increase the payload mass capacity. The booster employed for Starship Flight 11 static fire is Booster 15-2, which was first used during Starship Flight 8 and successfully recovered the booster with the tower catch.

During Flight 8, shut down all but three of its Raptor engines as planned for hot-staging separation. The booster then relit 11 of 13 planned Raptor engines and performed a boostback burn to return itself to its landing burn to slow down the rocket prior to tower catch.

The company sent the booster back to the Starship factory and refurbished it for this flight test. Currently, no plans have been revealed regarding the booster catch.

After this super-heavy static fire, the SpaceX team will now perform the same test for the Starship Flight 11 upper stage. However, the company has yet to announce the launch date for the Starship Flight 11.
