SpaceX's Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world's most powerful launch vehicle ever developed, with the ability to carry in excess of 100 metric tonnes to Earth orbit. Drawing on an extensive history of launch vehicle and engine development programs, SpaceX has been rapidly iterating on the design of Starship with orbital-flight targeted for 2020.


Starship is the fully reusable second stage and has an integrated payload section. Starship serves as a large, long-duration spacecraft capable of carrying passengers or cargo to Earth orbit, planetary destinations, and between destinations on Earth.

The first stage, or booster, of our next-generation launch vehicle has a gross liftoff mass of over 3 million kg and uses sub-cooled liquid methane and liquid oxygen (CH4/LOX) propellants. The booster will return to land at the launch site on its 6 legs.

The Starship payload fairing is 9 m in diameter and ~19 m high, resulting in the largest usable payload volume of any current or in development launcher. This payload volume can be configured for both crew and cargo.


SpaceX's Starship and Super Heavy rocket are designed to deliver satellites to Earth orbit and beyond, at a lower marginal cost per launch than our current Falcon vehicles. With a 9m diameter forward payload compartment, larger than any other current or planned fairing, Starship creates possibilities for new missions, including space telescopes even larger than the James Webb.


Starship can deliver both cargo and people to and from the International Space Station. Starship’s forward payload volume is about 1,100 m3, providing significant capacity for in-space activities. The aft cargo containers can also host a variety of payloads.


Returning to the Moon and developing bases to support future space exploration requires the transport of large amounts of cargo to the Moon for research and human spaceflight development. The fully reusable Starship system is capable of supporting this effort by carrying the building blocks needed to enable a Moon base and by informing the development of propulsive landing systems to help realize this future.


Building Moon bases and Mars cities will require affordable delivery of significant quantities of cargo and people. The fully reusable Starship system uses in-space propellant transfer to enable the delivery of over 100t of useful mass to the surface of the Moon or Mars. This system is designed to ultimately carry as many as 100 people on long-duration, interplanetary flights.

Raptor Engine

Raptor is a full-flow, staged combustion rocket engine powered by cryogenic methane and liquid oxygen (LOX), rather than the RP-1 kerosene and LOX used in SpaceX’s prior Merlin engine family. The Super Heavy booster is powered by 37 Raptors, while Starship is powered by 6.
