Aerospace is the human effort in science, engineering, and business to fly in the atmosphere of Earth and surrounding space. Aerospace organizations research, design, manufacture, operate, or maintain aircraft or spacecraft. Aerospace Engineers design and test missiles, aircraft, satellites, and spacecraft . They also create propulsion systems and evaluate the aerodynamic performance of aircrafts and assure all blueprints, prototypes, and products meet required engineering standards, environmental issues, and customer requirements. the branch of engineering that deals with the design, development, testing, and production of aircraft and related systems (aeronautical engineering) and of spacecraft, missiles, rocket-propulsion systems, and other equipment operating beyond the earth's atmosphere (astronautical engineering). Industry Overview: Aerospace. 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.
