View of the Earth’s atmosphere and the Moon beyond Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organizations research, design, manufacture, operate, or maintain aircraft or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications.
Over the years, Turkey has also emerged as an ideal place for civil aviation business. The number of airline passengers increased to 193 million in 2017, up from 34 million in 2004. The number of civilian aircraft increased from 626 to 1,417 between 2003 and 2016, with airline fleet size increasing to 540, up from 162. In the same period, the turnover in civil aviation reached USD 20 billion, up from USD 2.2 billion. Turkey is determined to position itself as a hub for civil aviation. A new airport is being constructed in Istanbul, and once completed it will be the largest airport in the world, with a capacity of 200 million passengers per year and flights to nearly 350 destinations.
Aerospace is not the same as airspace, which is the physical air space directly above a location on the ground. The beginning of space and the ending of the air is considered as 100 km above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity.
