Rockets are now used for fireworks, missiles and other weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration.Ĭhemical rockets are the most common type of high power rocket, typically creating a high speed exhaust by the combustion of fuel with an oxidizer. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology for the Space Age, including setting foot on the Moon. Rockets for military and recreational uses date back to at least 13th-century China. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations.

Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere.

Rocket engines work entirely from propellant carried within the vehicle therefore a rocket can fly in the vacuum of space.

A rocket engine produces thrust by reaction to exhaust expelled at high speed. A Soyuz-FG rocket launches from ' Gagarin's Start' (Site 1/5), Baikonur CosmodromeĪ rocket (from Italian: rocchetto, lit.'bobbin/spool') is a vehicle that uses jet propulsion to accelerate without using the surrounding air.
