Space is an exotic environment, utterly different from conditions here on Earth. There is almost no atmosphere, radiation levels are much higher, and there is a real risk of getting hit by debris traveling at supersonic speeds.
Aerospace engineers play an important role when it comes to the advancement and development of spacecraft, aircraft, missiles and satellites. They also focus on how to improve flight safety and fuel efficiency while minimizing environmental impact and operational costs.
There are five main ways that rocket engines are powered. They can be powered physically, chemically, electrically or by using either thermal or nuclear energy. Among these, chemically powered rocket engine is one of the more popular types.
The aerospace industry is unique in terms of what it looks for in materials, with the oil and gas industry being the closest. Since aircrafts need to be able to resist the force of gravity while maximizing air support, aerospace materials need to be lightweight but strong. At the same time, they need to be resistant to heat, fatigue and corrosion because these materials will be exposed to extreme temperatures and harsh environments.
