It is through space rocket man came into the fight with the forces of the Earth's gravity and won. And why bother to do multi-stage rocket? Is it not possible to create such a big powerful missile that would be dispersed spacecraft to at least the first cosmic speed? Admire aircraft and all sorts of interesting pieces then you have to! Rolled addition missiles and can admire and enjoy the view of this miracle of technology.
Space rocket - multistage rocket to output spacecraft (satellites, AU, spacecraft) into orbit or interplanetary satellite track. She - the only means of penetration into space, the most perfect work of human hands holding today record speed and range. The principle of jet propulsion, known since ancient times, people used to penetrate the Earth into space only in the XX century.
Rocket aircraft is moving through space by the action of the Jet Propulsion arising from the rejection of its own weight (body work) system without the use of substances from the environment.
Since the flight of the missile does not require the presence of ambient air or gas environment, the movement of missiles is possible not only in the atmosphere but in a vacuum. Word rocket flying denote a wide range of devices from festive firecrackers to space launch vehicle.
