The Starship system is a fully reusable, two‑stage‑to‑orbit super heavy‑lift launch vehicle under development by SpaceX. The system is composed of a booster stage, named Super Heavy, and a second stage also referred to as Starship. The second stage is being designed as a long‑duration cargo and passenger‑carrying spacecraft. The spacecraft will serve as both the second stage and the in‑space long‑duration orbital spaceship.
