Starship never left the ground in 2022, held up by FAA environmental review and Raptor/booster readiness. The first integrated flight attempt came April 20, 2023 and exploded about four minutes in; Starship did not complete a near-orbital trajectory until March 2024.

At the February 10, 2022 Starship update in front of a fully stacked Booster 4 / Ship 20, Musk said he was 'highly confident' Starship would reach orbit that year — a restatement of orbital-flight promises dating to 2019 ('orbital by March 2020') and 2020 ('orbital 2021'). Starship did not fly at all in 2022; the first launch attempt in April 2023 ended in an explosion over the Gulf.
