The application of engineering principles to aerospace systems such as aircraft, spacecraft, and ground control systems. Formerly known as aeronautical engineering, concerns the design, construction, and science of both air and space vehicles, primarily on the systems level. Further concerned with the science of force and physics that are particular only to performance in Earth's atmosphere, and the expanse of space. Often placed within Vehicle engineering.
Aeronautics, the design and development of aircraft and air traffic control systems
Astronautics, the design and development of spacecraft with an emphasis on spacecraft systems, the design of ground control systems for spacecraft, and the design of orbital mechanics for spacecraft missions
