SpaceX flew Starship five times in 2025. The first three flights lost their ships during ascent. A fourth ship exploded on the test stand. Then Flights 10 and 11 succeeded, proving Block 2 works. Meanwhile, SpaceX is constructing Giga Bays in Texas and Florida to build 80-meter Block 4 boosters, preparing five launch pads across two states, and developing barge transport to ship vehicles from Starbase to Kennedy Space Center. Flight 12 with Block 3 hardware is next.
