what is Aerospace?

Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications.

Contrary to general understanding, aerospace is not the same as airspace. The latter is the physical air space directly above a location on the ground. 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.

They include Indian Space Research Organisation (ISRO), NASA, ESA, Canadian Space Agency in Canada, Japanese Aeronautics Exploration Agency in Japan, RKA and China National Space Administration. Aerospace manufacturing is a high-technology industry that produces "aircraft, guided missiles, space vehicles, aircraft engines, propulsion units, and related parts".

Most of the industry is geared toward governmental work. For each original equipment manufacturer (OEM), the US government has assigned a Commercial and Government Entity (CAGE) code. In India, Bangalore is a major center of the aerospace industry, where Hindustan Aeronautics Limited (HAL) and National Aerospace Laboratories are headquartered.
