Expert Answer:

The fuel in the spaceships is stored in external fuel tank.Taking an example of one of the satellites ,its engines burn liquid hydrogen and liquid oxygen, which are stored in the external fuel tank (ET), at a ratio of 6:1. They draw liquid hydrogen and oxygen and it is partially burned in a pre-chamber to produce high pressure, hot gases that drive the turbopumps (fuel pumps). The fuel is then fully burned in the main combustion chamber and the exhaust gases (water vapor) leave the nozzle at approximately 6,000 mph (10,000 km/h).
