Q:

Which kind of rocket engines are used on the space shuttle?

A:

The space shuttle's main engines are incredibly large and powerful machines. You can see them on the back of the shuttle, three huge engines grouped together. They are not to be confused with the large boosters that help the shuttle take off. They burn liquid hydrogen and liquid oxygen, and create 544,000 kg (1.2 million lbs) of thrust
