Fuel Cell Use in the Space Shuttle. Fuel cells are used in the space shuttle as one component of the electrical power system. Three fuel cell power plants, through a chemical reaction, generate all of the electrical power for the vehicle from launch through landing rollout. Before launch, electrical power is provided by ground power supplies and ...
Originally Answered: What fuel does the space shuttle use? The three main engines of the Space Shuttle used liquid oxygen and liquid hydrogen as fuel. There are many different ways of pricing these two, depending on the use, but I doubt you'll find a set $/gallon price out there. NASA contracts may shed some light on this.
NASA's Space Transportation System (STS) vehicle, better known as the Space Shuttle, used two single engine Solid Rocket Boosters (SRB) as Stage 0, an engineless external tank providing propellant for the three Space Shuttle Main Engines (SSME) on the orbiter as stage 1, and additional two Orbital Maneuvering System (OMS) hypergolic liquid-propellant rocket engines on the Space Shuttle orbiter as stage 2.
The Shuttle had three propulsion systems: the solid rocket boosters (SRB), mounted at the side. the main engines (SSME), mounted in the orbiter and fed from the external tank. the orbital manoeuvring system (OMS), mounted in the orbiter and fed from tanks inside the orbiter. During launch, the SRBs were fired until they burned out, and the SSMEs ...
The ET from STS-115 after separation from the orbiter. The scorch mark near the front end of the tank is from the SRB separation motors. The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer.
