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.
Technically Aerospace Engineering is a specialized area within Mechanical Engineering, focused towards aircraft/spacecraft. To become an Aerospace Engineer, one needs to have very strong analytical and critical thinking skills because the problems that need to be solved in this field are very complex. Hence, colloquially, Aerospace Engineering is what everyone refers to as 'Rocket Science'.
