SpaceX Starship: 11th launch and successful splashdown

STARBASE, Texas (ValleyCentral) — A crowd of people gathered around to witness SpaceX launch its 11th Starship test flight on Monday evening in Starbase.

At approximately 6:25 p.m., SpaceX launched its 11th test flight to space from Boca Chica Beach.

SpaceX’s primary goal for this launch was to test the vehicle’s dynamics as the engines shut down while it transitions through its different phases.

At approximately 6:31 p.m., the Super Heavy reentered, where it ignited the 13 engines at the start of the landing burn, before transitioning to five engines. It then transitioned to three engines, followed by a splashdown in the Gulf.

While in space, Starship’s ascent burn was completed, and coasted through space before successfully deploying Starlink simulators.

At approximately 7:04 p.m., Starship ignited one of its Raptor engines while in space.

At approximately 7:30 p.m., Starship made a successful splashdown into the Indian Ocean, confirmed by the SpaceX team.

SpaceX’s Goal

According to SpaceX, the test flight has been built upon the successful demonstrations from the 10th Starship test flight, following the data gathered from the Super Heavy booster, which stress-tests Starship’s heat shield and demonstrates maneuvers that will mimic the upper stage’s final approach to the launch site.

SpaceX has worked with the FAA and international air traffic organizations to plan how to efficiently and safely launch and reenter all operations into airspace.

During the 10th Starship test flight, the FAA had reopened all affected airspace within nine minutes, and some portions were reopened within seven minutes, with no meaningful disruption to air traffic.

In this launch, the booster was previously used on test flight 8, and launched with 24 flight-proven Raptor engines.

According to SpaceX, the main objective of the 11th launch was to demonstrate a unique landing burn engine configuration planned to be used on the next-generation Super Heavy.

This configuration was attempted while on a trajectory to an offshore landing point in the Gulf and will not return to the launch site for the catch.

The Super Heavy ignited 13 engines at the start of the landing burn, before transitioning to a new configuration with five engines running for a divert phase.

SpaceX states this configuration was previously done with three engines, and was planned with a baseline for V3 Super Heavy to use five engines during the section of the burn responsible for fine-tuning the booster’s path and adding additional backup for spontaneous engine shutdowns.

The booster was planned to then transition to its three center engines for the end of the landing burn, entering a full hover while still above the ocean surface, followed by a shutdown and dropping to the Gulf.

Additionally, the test flight included several experiments and operational changes that focus on enabling Staship’s upper stage to return to launch on future flights.

SpaceX stated that for reentry, tiles were removed from Starship to intentionally stress-test the vulnerable areas across the ship.

Additionally, several of the missing tiles are in areas where the tiles are bonded to the ship and do not have a backup sacrificial thermal protection system to protect the vehicle.

According to SpaceX, to mimic the path a ship will take on future flights returning to Starbase, the final phase of Starship’s path on test flight 11 included a controlled reorientation and will test the subsonic guidance algorithms before a landing burn and splashdown in the Indian Ocean.
