Starship Flight Test 4 will be the 4th flight of Starship. The current launch date is May 2024. SpaceX confirmed that Ship 29 (S29) and Booster 11 (B11) will be used for this mission. Both vehicles will be amended based on corrective actions found in the mishap investigation for Flight 3, which is speculated to be better control of the ship to prevent burning up on re-entry.
