SpaceX is preparing to launch Starship Flight 12, the maiden flight of Block 3 vehicles. Booster 19 and Ship 39 will fly with Raptor 3 engines for the first time, generating 19 to 22 percent more thrust than Block 2. The launch window opens in late February or March 2026 from Pad 2 at Starbase. SpaceX will not attempt a booster catch on this flight. Ship 39 will attempt a controlled reentry over the Indian Ocean. The orbital refueling demonstration planned for June 2026 depends on Flight 12 succeeding, and NASA's Artemis program has no backup plan. We talk about Starship Flight 12 Technical Report, SpaceX production timeline and testing milestones, FCC communications window filing and NASA Artemis program dependencies.The Starship system is a fully reusable, two‑stage‑to‑orbit super heavy‑lift launch vehicle under development by SpaceX. The system is composed of a booster stage named Super Heavy and a second stage, also called "Starship" and is being built at Starbase, Texas.
