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.
Aerospace engineers use the principles of calculus, trigonometry, and other advanced topics in mathematics for analysis, design, and troubleshooting in their work. Aerospace engineers must have a bachelorâs degree in aerospace engineering or another field of engineering or science related to aerospace systems. Aerospace engineers that work on projects that are related to national defense may need a security clearance.
