The company will also use Starship's next flight to assess new tiles and other elements of the vehicle's heat shield.

"Several thermal protection experiments and operational changes will test the limits of Starship’s capabilities and generate flight data to inform plans for ship catch and reuse," the company's statement said. "The flight test will assess new secondary thermal protection materials and will have entire sections of heat shield tiles removed on either side of the ship in locations being studied for catch-enabling hardware on future vehicles. The ship also will intentionally fly at a higher angle of attack in the final phase of descent, purposefully stressing the limits of flap control to gain data on future landing profiles."

Final flight of the first Starship

The five previous flights of Starship, dating back to April 2023, have all launched near dawn from South Texas. For the upcoming mission, the company will look for a late-afternoon launch window, which will allow the vehicle to reenter during daylight into the Indian Ocean.

SpaceX's update also confirms that this will be the last flight of the initial version of the Starship vehicle, with the next generation including redesigned forward flaps, larger propellant tanks, and newer tiles and secondary thermal protection layers.

Reaching a near-monthly cadence of Starship flights during only the second year of the vehicle's operation is impressive, but it's also essential if SpaceX wants to unlock the full potential of a rocket that needs multiple refueling launches to support Starship missions to the Moon or Mars.

Wednesday's announcement comes the day after the US presidential election in which Donald Trump was given a second term by American voters, and it is notable that he was assisted in this through an all-out effort by SpaceX founder Elon Musk.

Musk's interventions in politics were highly controversial and alienated a significant segment of the US population and political class. Nevertheless Musk's gambit paid off, as the election of Trump will now likely accelerate Starship's development and increase its centrality to the nation's space exploration endeavors.

However, the timing of this launch announcement is likely coincidental, as SpaceX did not need formal regulatory approval to move ahead with this sixth attempt—it was almost entirely dependent on the readiness of the company's hardware, software, and ground systems.
