SpaceX has announced a series of upgrades to its Starship vehicle in order to improve its performance and capabilities. Following its debut during the Integrated Flight Test One (IFT 1), the company has focused on enhancing the launch site and Booster 9. While final regulatory approval is still pending, these upgrades show promising advancements for the future of the Starship program.
One significant change being made to Booster 9 is the transition from Raptor 2 to Raptor 2.1 engines. The new engines utilize electric Thrust Vector Control (TVC) instead of hydraulics, allowing for quicker and smoother gimbaling action during flight. Additionally, upgrades have been made to the Raptors and valves of Booster 9 to reduce methane leakage into the engine compartment and mitigate methane buildup during flight and static fires.
Another notable improvement is the upgraded engine shielding for Booster 9 compared to its predecessor, Booster 7. This upgrade not only simplifies the design but also improves maintenance access, making it easier to perform necessary repairs and inspections.
Booster 9 also features several other upgrades, including a newly designed methane transfer tube, four new vents at the top of the interstage, and an upgraded flight termination system (FTS). The FTS is designed to destroy the full stack in case of an emergency, ensuring the safety of the vehicle and its crew.
In addition to the upgrades being made to Booster 9, Ship 24 and Ship 25 have also undergone significant improvements. Both ships now utilize Raptor 2 engines and have been equipped with a heat shield made of tiles for enhanced protection during flight.
One notable difference between Ship 24 and Ship 25 is the welded shut payload bay on Ship 25. This addition provides added protection during flight loads, ensuring the safety of any cargo being transported.
Both ships have also received engine shielding upgrades and additional vents to prevent methane buildup and purging of the engine skirt. The FTS on Ship 25 has been upgraded with an extra charge above the common dome, further enhancing safety measures during flight.
These upgrades mark a significant step forward in SpaceX’s Starship program. The company aims to achieve stage separation and ignition as the primary goals for the next flight, and these enhancements will be crucial in reaching that objective. With final regulatory approval still pending, SpaceX is poised to revolutionize space travel with its upgraded Starship vehicle.
