“The Starship launch vehicle is made up of the Super Heavy first-stage booster and the Starship second stage. The second stage functions as a self-contained spacecraft for carrying crew or cargo once in orbit.”
“Super Heavy is a first stage or booster stage, and forms the lower part of the rocket.”
“Starship is a second stage or long-duration spacecraft, and forms the upper part of the rocket.”
“Both stages are powered by Raptor engines that burn liquid oxygen and liquid methane propellants in a highly efficient, full-flow staged combustion power cycle. Both rocket stages are designed to be reused by landing vertically at the launch pad or at a separate platform.”
GIF is the second stage but the two stages combined make up the SpaceX Starship.
