"SpaceX's Upgraded Starship Set for Test Flight Pending FAA Approval"

SpaceX is preparing for an upcoming test flight of its Starship vehicle and has made several upgrades to Booster 9 and the launch site pending FAA approval. The changes to Booster 9 include the use of electric TVC for smoother gimbaling action, upgrades to the methane turbopumps and manifolds to reduce methane leakage, improved engine shielding, and enhancements to the flight termination system. The addition of a hot staging ring on the booster allows the ship's engines to be fired while still attached, improving performance. Ship 24 and Ship 25 have also undergone upgrades, including the use of Raptor 2 engines, a heat shield made of tiles, and a welded shut payload bay. SpaceX hopes to achieve stage separation and ignition during the next flight.
