Aerospace engineering is a field of engineering that deals with development and design of aircraft, spacecraft, satellites and missiles. They come up with new technologies for use in aviation and defense systems. Aerospace engineering is divived into 2 major types of engineering: aeronautical or astronautical engineering.
Aeronautical engineering deals with aircrafts, designing aircraft, studying aerodynamic performance, navigation and control of aircrafts.
Astronautical engineering deals with spacecrafts, studying astrodynamics performance, aerospace control, technology of spacecraft, aerospace operation and how spacecraft works inside and outside the atmosphere.
