Astronautics is the branch of engineering that deals with machines designed to work outside of Earth's atmosphere, whether manned or unmanned. In other words, it is the science and technology of space flight. Layers of Atmosphere (NOAA) Air redirects here. ...

Astronautics was coined by analogy with aeronautics. As with aeronautics, the restrictions of weight, heat and external forces require that applications in space survive extreme conditions, whether the heat of reentry, the radiation bombardment of interplanetary space, or the magnetic belts of orbit, space vessels must be designed to withstand forces almost unknown on Earth. Moreover, because of the extreme constraints on weight, astronautic engineering is constantly faced with the need to reduce the mission payload, in order to save propellant that powers the impulse engine. Earth (often referred to as the Earth) is the third planet in the solar system in terms of distance from the Sun, and the fifth in order of size. ... In cargo transport, the payload is the valuable contents of the vehicle. ... A propellant is a material that is used to move an object by applying a motive force. ... In classical mechanics, the impulse of a force is the product of the force and the time during which it acts. ...

The early history of astronautics is theoretical; long before it was possible to send vessels into space, the question of space flight interested such figures as Jules Verne and HG Wells. The practical history of astronautics begins with liquid-fueled rockets. Jules Verne. ... H. G. Wells at the door of his house at Sandgate Herbert George Wells (September 21, 1866 - August 13, 1946) was an English writer best known for his science fiction novels such as The War of the Worlds and The Time Machine. ... A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine. ...

Branches of astronautics are space mathematics, astrodynamics, space environment, spacecraft design, rocketry, attitude dynamics and control, navigation. The purpose of this article is to introduce non-scientists, non-engineers, and other laymen to the basic mathematics of space exploration. ... Astrodynamics is the study of the motion of rockets, missiles, and space vehicles, as determined from Sir Isaac Newtons laws of motion and his law of universal gravitation. ... Space environment is a branch of astronautics and aerospace engineering that seeks to understand and address conditions existing in space that would impact the operation of spacecraft, such as radiation, space debris, upper atmospheric drag, and the solar wind. ... The design of spacecraft covers a broad area to include satellite design, planetary probe design, and manned spaceship design. ... A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine. ... Attitude dynamics and control is a term used in rocketry and spacecraft. ... Table of geography, hydrography, and navigation, from the 1728 Cyclopaedia. ...
