Etymology
Origin of aerospace
Explanation
The science of airplanes and rockets is known as aerospace. If you're interested in launching rockets or building jets, you should consider a career in aerospace. The term aerospace was coined in the U.S. during the mid-20th century, from aeronautics, the study of planes and other flying machines, and spaceflight. The aerospace industry includes a lot of flying craft, including commercial airplanes, unpowered gliders, military jets, missiles, and space shuttles. Aerospace engineers design these vehicles and develop ways to make them safer and more efficient, as well as testing and maintaining them.
