First idea of a rocket ws devloped by Russian school master konstanantin Tsiolkovski in 1903.the cargo that a rocket carries is called a payload and the payload maybe astronauts or satellites. The larger the rocket, the heavier the payload can be.space travel actually started when American engineer Robert goddard launched the first liquied fuel roket.

A Rocket needsto carry huge ammount of fuel to pick up speed and the heavier the rocketthe more fuel it will need.Rocket fuel consits of two liquieds. The liquieds explode when mixed wich pushes the rocket forward.Then the stages fall off to make the load less, and the containers are called stages.The fuel is not carried in one tank but in different containers are called velocity is the speed which a rocket needs to getout of the Earths gravity.

Earth has tremendous gravity.a rocket must reach a speed of 40,000 kiloeteres per hour to get out of this gravity.Rocketes are launched from space and there are about fifteen launch sites around the world.
