Aerospace

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 airspae, which is a term used to describe the physical air space directly above a location on the ground.
In most industrial countries, the aerospace industry is a cooperation of public and private industries. For example, several countries have a space program under the command of the government, such as NASA in the United States, ESA in Europe the Canadian Space Agency in Canada, Indian Space Research Organisation in India, RKAin Russia, China National Space Administration in China, and Iranian Space Agency in Iran.
Along with these public space programs, many companies produce technical tools and components such as spaceships and satellites. Some known companies involved in space programs include Lockheed Martin, Northrop Grumman, EADS, and Boeing. These companies are also involved in other areas of aerospace such as the construction of aircraft.
The field of aerospace has been investigated for millennia, but modern aerospace began with the first powered flight at Kitty Hawk, North Carolina 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.
