"SpaceX's Starship system represents a fully reusable transportation system designed to service Earth orbit needs as well as missions to the Moon and Mars. This two-stage vehicle--composed of the Super Heavy rocket (booster) and Starship (spacecraft) as shown in Figure 1--is powered by sub-cooled methane and oxygen. Starship is designed to evolve rapidly to meet near term and future customer needs while maintaining the highest level of reliability.
Starship has the capability to transport satellites, payloads, crew, and cargo to a variety of orbits and Earth, Lunar, or Martian landing sites. Potential Starship customers can use this guide as a resource for preliminary payload accommodations information. This is the initial release of the Starship Users Guide and it will be updated frequently in response to customer feedback."
