Jet engines and liquid rocket engines have much in common. Both pump fuel and oxidizer into a combustion chamber to develop ... nozzle. The major conceptual difference is that rockets carry their oxidizer with them whereas jet engines use air as their source of oxygen. In rocket engine terminology, the term "jet" usually refers to the stream of ...

The largest rocket ever built was the Saturn V rocket that was used to carry people to the Moon and back. This rocket was about 363 feet tall and weighed about 2,250 metric tons when fully fueled. The Space Shuttle with the external tank and solid rocket boosters is a little over 184 feet tall and weighs about 2000 metric tons. ---- Answer ... /For%20Kids/KidstoSpace.html Click here Category:Kids To Space Category:Kids To Space - ROCKETS
