#4609 MAGIC: Transfer Kinetic and Potential Energy from Orbiting Spacecraft to One on the Pad #4609 Describe the engine and propellant arrangement for SpaceX Starship The SpaceX Starship launch system—comprising the Super Heavy Booster (Stage 1) and the Starship Spacecraft (Stage 2)—utilizes a tightly integrated, highly efficient engine and propellant configuration designed around deep cryogenic liquids and full-flow staged combustion. 1. The Propellants: Methalox Both stages utilize the exact same liquid propellant combination, known colloquially as Methalox : Fuel: Liquid Methane ( CH_4 ) Oxidizer: Liquid Oxygen ( LOX ) Choosing methane over traditional rocket kerosene (RP-1) or liquid hydrogen ( LH_2 ) offers a balance of high performance, easier storage temperatures, a lack of heavy carbon coking inside the engines (crucial for rapid reuse), and the ability to be synthesized on Mars via the Sabatier process. Both liquids are chilled to sub-cooled, cryogenic tempe...
