Starship

Starship is a spacecraft and second stage under development by American aerospace company SpaceX. Stacked atop its booster, Super Heavy, the pair compose SpaceX's super heavy-lift space vehicle, also called Starship. The spacecraft is designed to transport both passengers and cargo to a variety of destinations, including Earth orbit, the Moon, and Mars. It is designed to be reusable and capable of landing propulsively by firing its engines to perform a controlled descent into the arms of a tower on Earth or with landing legs on other planetary bodies. It is intended to enable long-duration interplanetary flights with up to 100 passengers. It is also claimed by SpaceX to be capable of enabling travel to anywhere on Earth in under an hour. Furthermore, it has been proposed to be used to refuel other Starship spacecraft, enabling them to reach higher orbits and other space destinations. Elon Musk, the CEO of SpaceX, estimated in a tweet that eight launches would be needed to completely refuel a Starship in low Earth orbit. However, some estimates include as many as twenty refueling flights.
