SpaceX Starship

Starship is a two-stage, fully reusable, super heavy-lift launch vehicle under development by SpaceX, built and launched from Starbase in Texas and intended as the successor to the Falcon 9 and Falcon Heavy rockets. It consists of the Super Heavy booster and the Starship spacecraft, both powered by Raptor engines burning liquid methane and liquid oxygen, and both intended to return to the launch site and land vertically for reuse. In space the upper stage is meant to work as a standalone spacecraft for crew and cargo, with missions beyond low Earth orbit needing several in-orbit refueling flights. SpaceX first expressed ambitions of crewed Mars missions but revised the plan to prioritize returning humans to the Moon, and a crewed variant, the Starship Human Landing System, is being developed under a NASA contract for the Artemis program. Development follows an iterative approach with many prototype vehicles and test flights.
