Which kind of rocket engines are used on the space shuttle and why?
Space Shuttle Main Engines (SSME) are Rocketdyne RS-24 liquid-fuel rocket engines powered by liquid hydrogen and liquid oxygen. The Solid Rocket Boosters used during ascent are solid fuel rockets manufactured by Thiokol Corporation fueled by a mixture of ammonium perchlorate oxidizer, aluminum, an iron oxide catalyst and polymers as a binding agent.
What are the advantages of liquid fuel rocket engines?
There are two types of rockets -- those that use liquid fuel and those that use solid fuel. Liquid fuel rockets have two main advantages. Liquid fuel rocket engines burning can be controlled. That is, they can be turned on and off, and their thrust (pushing force) can be controlled/varied. Second, they produce more thrust for the same amount (weight) of fuel -- called specific impulse. Liquid fuel is also cheaper, but that's rarely a consideration as it is such a small part of the cost.
What controls the thrust of a rocket?
Liquid rocket engines would act much like a car engine. More fuel, more thrust. Solid rocket engines are either on or off. No throttle control.
What is the difference between a space shuttle and a rocket?
Answer The Space Shuttle is a rocket. By definition, a Rocket is a vehicle that burns gas that it carries with it. Where as, a jet airplane burns the oxygen from the air and is not a rocket. The Rocket when it is launched has a liquid fuel rocket engines at the back end of it. It also has two long, solid fuel rocket engines that separate after launch. But the space shuttle is pulled by a rocket.
What does a space shuttle run on?
The orbiter's main engines are fueled by liquid oxygen and liquid hydrogen. The 2 solid rocket boosters which provide additional lift during the first 2 minutes of flight are powered by solid propellent consisting of ammonium percholate, iron oxide, and aluminum. Electrical power is provided by fuel cells.
What are two main types of rocket engines?
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Can you shut off a liquid fueled rocket?
Yes. That is an advantage of a liquid fueled rocket. On the other hand, a solid fueled rocket is simpler and therefore cheaper but once it is started, you have to wait until it burns itself out.

Did Robert h goddard invented the rocket?
No, the Chinese had rockets thousands of years earlier, but they were solid fueled and unguided.

How many types of rockets are there?
There are two main types of rocket engines: Solid fuel and liquid fuel. Liquid fuel rocket engines are usually considered significantly better than solid propulsion units, however, they are also significantly more expensive.

How does space shuttle get into space?
By the use of it's three Main Engines and two Solid Rocket Boosters.

How does a space shuttle get to space?
The first stage would be launch of course, which uses the main engines (three liquid fueled rockets) and the two Solid Rocket Boosters that are ignited right after the main engines start. After 2 minutes the Boosters are done and are released, while the main engines continue until the shuttle is going fast enough for orbit. The total time from launch to orbit is 9 minutes.
