SpaceX has stacked Starship's two elements — the Super Heavy booster and Ship upper-stage spacecraft — on the orbital launch mount at its Starbase site in South Texas. The company confirmed the milestone in a Friday night X post, which featured four photos of the stacking process and its aftermath. A fully stacked Starship stands nearly 400 feet (122 meters) tall. (Image credit: SpaceX via X) That post also announced a date change for the flight: It has slipped from Monday (Nov. 18) to Tuesday (Nov. 19). Liftoff will occur during a 30-minute window that opens at 5 p.m. EST (2100 GMT; 4 p.m. local Texas time).
