Aerospace comprises the atmosphere of Earth and surrounding space. Typically, aerospace industries combine aeronautics and astronautics to research, design, manufacture, operate, or maintain vehicles moving through air and through space. Aerospace is a very diverse field, with a multitude of commercial, industrial and military applications.
In most industrial countries, the aerospace industry is a cooperation of public and private industries. For example, several countries have a civilian space program funded by the government through tax collection, such as NASA in the United States, ESA in Europe, the Canadian Space Agency in Canada, Indian Space Research Organisation in India, JAXA in Japan, RKA in Russia, China National Space Administration in China, SUPARCO in Pakistan, Iranian Space Agency in Iran, and Korea Aerospace Research Institute (KARI) in South Korea.
Along with these public space programs, many companies produce technical tools and components such as spaceships and satellites. Some known companies involved in space programs include Boeing, EADS, Lockheed Martin, MacDonald Dettwiler and Northrop Grumman. These companies are also involved in other areas of aerospace such as the construction of aircraft.
