The main engines develop thrust by using high-energy propellants in a staged combustion cycle. Their turbines spin almost 13 times as fast as an automobile engine spins when it is running at highway speed. As they push the Shuttle toward orbit, the engines consume liquid fuel at a rate that would drain an average family swimming pool in under 25 seconds generating over 37 million horsepower. The engines' exhaust is primarily water vapor as the hydrogen and oxygen combine. The main engines burn liquid hydrogen - the second coldest liquid on Earth at minus 423 degrees Fahrenheit (minus 252.8 degrees Celsius) - and liquid oxygen. They create a combined maximum thrust of more than 1.2 million pounds.Īs the Shuttle accelerates, the main engines burn a half-million gallons of liquid propellant provided by the large, orange external fuel tank.
