What Is Aerospace Engineering?

The design, development, testing, and manufacturing of vehicles that go through the atmosphere and beyond are the main objectives of aerospace engineering, a specialist area of mechanical engineering. There are two primary disciplines within this field: aeronautical engineering and astronautical engineering.

  • Aeronautical engineering deals with aircraft that operate within Earth’s atmosphere, such as planes, helicopters, and drones.
  • Astronautical engineering focuses on spacecraft and systems that travel beyond the atmosphere, including rockets, satellites, probes, and rovers.

History of Aerospace Engineering

Since the first flight of the Wright brothers, Gagarin's first trek beyond our atmosphere, and Armstrong's step on another world; aerospace engineering has rapidly evolved in the 20th century. Early advancements focused on aviation, while the mid-20th century saw the rapid rise of astronautics during the Space Race. Today, the field spans everything from uncrewed aerial vehicles (UAVs) to interplanetary exploration missions.

Frequently Asked Questions

Is aerospace engineering hard?

Yes, it requires strong skills in math, physics, and engineering principles, along with creativity and problem-solving abilities.

What distinguishes mechanical engineering from aerospace engineering?

Aerospace engineering is a subfield of mechanical engineering that focuses on aircraft and spacecraft. Mechanical engineering, on the other hand, deals with a wider variety of systems.

What is the salary of an aerospace engineer?

Although salaries vary, the median yearly salary for engineers in the United States is approximately $125,000, with experienced engineers making much more.
