How does a rocket take off? Rockets need to escape the Earth's gravity - the force pulling objects towards the Earth. To do this, they must generate a huge amount of thrust - the force that pushes the rocket upwards. Rockets carry a lot of fuel. This fuel burns slowly and generates lots and lots of heat.
A steam engine is used to do the same thing, as is a steam turbine and most gas turbines. Rocket engines are fundamentally different. Rocket engines are reaction engines. The basic principle driving a rocket engine is the famous Newtonian principle that "to every action there is an equal and opposite reaction."

Now we know what space is, it's easier to understand what a rocket is and how it works. A space rocket is a vehicle with a very powerful jet engine designed to carry people or equipment beyond Earth and out into space. If we define ...
Many small cheap rockets aren't very good at staying upright. More advanced rockets have an electronic guidance system. Years ago these used mechanical gyroscopes, but most these days they use electronic systems. The rocket is usually kept straight by steering the exhaust from the rocket engine.
A rocket launch is the takeoff phase of the flight of a rocket.Launches for orbital spaceflights, or launches into interplanetary space, are usually from a fixed location on the ground, but may also be from a floating platform or from an airplane.. Launches of suborbital flights (including missile launches), can also be from: . a missile silo; a mobile launcher vehicle
To launch this enormous rocket off the ground, NASA used five F-1 rocket engines, the most powerful rocket engines ever flown. The thrust needed to be greater than the weight force of nearly 28,700,000 N. The engines produced a thrust at lift-off of 33,400,000 N (enough to lift 487 school buses!).
Rockets need so much fuel in order to overcome Earth’s gravity. Only when they reach a speed of 28 000 km/h are they travelling fast enough to enter orbit. Most rockets are made up of two or three stages. When a stage has used up all of its fuel, it is separated to get rid of the dead weight.
Fran Scott demonstrates how rockets lift off during a launch into space. This is how British astronaut, Tim Peake has managed to reach the International Space Station. Scientists and engineers ...
The space shuttle takes off on July 4th, first lift off on July 4th. I honestly find it amazing how much thrust this baby has pushing it towards space...
