NASA engineers, like the ones depicted in Apollo 13,
worked diligently to save the lives of the astronauts
on the mission.
Fields of employment
Aerospace engineering is the branch of en-
gineering behind the design, construction
and science of aircraft and spacecraft.
Aerospace engineering has broken into two
major and overlapping branches: aeronautic-
al engineering and astronautical engineering.
The former deals with craft that stay within
Earth’s atmosphere, and the latter deals with
craft that operate outside of Earth’s atmo-
sphere. While "aeronautical" was the original
term, the broader "aerospace" has super-
seded it in usage, as flight technology ad-
vanced to include craft operating in outer
space. Aerospace engineering is often in-
formally called rocket science.
Modern flight vehicles undergo severe condi-
tions such as differences in atmospheric
pressure and temperature, or heavy structur-
al load applied upon vehicle components.
Consequently, they are usually the products
of various technologies including aerodynam-
ics, avionics, materials science and propul-
sion. These technologies are collectively
known as aerospace engineering. Because of
the complexity of the field, aerospace engin-
eering is conducted by a team of engineers,
each specializing in their own branches of
science., The development and manufac-
turing of a flight vehicle demands careful bal-
ance and compromise between abilities,
design, available technology and costs.
