Aerospace comprises the atmosphere of Earth and surrounding space. Typically the term is used to refer to the industry that researches, designs, manufactures, operates, and maintains vehicles moving through air and space. Aerospace is a very diverse field, with a multitude of commercial, industrial and military applications.Aerospace is not the same as airspace, which is a term used to describe the physical air space directly above a location on the ground. Aerospace engineering is the branch of engineering that concerns the design, construction and science behind aircraft and spacecraft. Aerospace engineering has broken into two major branches, aeronautical 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 atmosphere. While "aeronautical" was the original term, the broader "aerospace" has superseded the it in usage, as flight technology advanced to include craft operating in outer space. Aerospace engineering is often informally called rocket science in common terms. The field of aerospace has been investigated for centuries but it can be said that modern aerospace began with the first powered flight at Kitty Hawk on December 17, 1903, by the Wright brothers. From there, aerospace has grown to be one of the most exciting, diverse, and fast paced fields of today. From the hot-air balloons of 18th century to the first wood-and-cloth plane of Wilbur and Orville Wright to the first manned mission to the moon on Apollo 11 to the new and exciting aircraft being developed by companies like Boeing, Airbus, and Bombardier, aerospace has come a long way in a little over a century. Modern flight vehicles must undergo severe conditions such as differences in atmospheric pressure and temperature, or heavy structural load applied upon vehicle components; numerous matters must be taken into account, especially during the design and manufacture of the flight vehicle. Consequently, they are usually the products of a complex synthesis of various technologies and sciences, including but not limited to aerodynamics, avionics, materials science and propulsion. The knowledge and the process of combining these various branches of studies is collectively known as aerospace engineering. Because of the complexity of the field, aerospace engineering is conducted by a team of engineers, each specializing in their own branches of science. The development and manufacturing of a flight vehicle demands careful balance and compromise between abilities, performance, available technology and costs. Popular culture has not been unaffected by this branch of engineering. The term "rocket scientist" is at times used to describe a person of remarkable or in the considered context higher than average intelligence. Aerospace engineering has also been represented as the more "glittery" pinnacle of engineering. The movie Apollo 13 depicts the ground team as a group of heroes in a Hollywood fashion glorifying the intelligence and competence of white shirt and tie professionals as a sharp contrast to pop culture trends. This was later extended in more detail in the spin-off series From the Earth to the Moon.
