Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain aircraft and spacecraft.

The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity.

Technological progress is the basis for competitiveness and advancement in the aerospace industry. The industry is, as a result, a world leader in advancing science and technology. Aerospace systems have a very high value per unit weight and are among the most complex, as measured by the number of components in finished products.

Consequently, it is economically and politically prestigious for a country to possess an aerospace industry. Among the world’s largest manufacturing industries in terms of monetary value of product output and employment, the aerospace industry is characterized by a relatively small number of large firms and numerous international partnerships at every level.
