A Rocket Engine

A rocket engine is symply a jet engine that carries its own supply of oxygen. But have you ever think how a rocket can launch into space? Hope this could answer your question.


A rocket is made from three parts of stage. At the bottom of a rocket engine contains with fuel and oxygen tanks is called the first stage. When it blasts off, the first stage lifts the whole rocket high into atmosphere. The first stage engine stops because the fuel and oxygen have been used up. Now the first stage is separated from the rest of the rocket, and drop away. Thus the rocket is rid of all the weight of the first stage.


The second stage engine starts up. Because the rocket is now lighter, it can go farther with the fuel remaining. When the second stage engine runs out of fuel and oxygen, the second stage is separated, and drop away. Now the rocket is lighter still. The third stage engine starts up and hurls the payload of instruments or people, into space.


That is how a rocket with people like satellite, or astronauts and all the instrument can reach the moon. Hope this information can be useful to us.
