How do we define the boundary of space and what can it be important for? There are many other space edge theories: from the concept of free molecular flow to the NASA limitation at 80 kilometers or 50 miles. To tell you the truth, this is only an attempt to define the space boundary that is used by the Fédération Aaéronautique Internationale (FAI) based in Lausanne, Switzerland, an international record-keeping body for aeronautics. So why is this interpreted as the edge of space? However, even there the atmosphere still exists and it lasts for many kilometers and miles. The Karman line (Kármán line) or can be found between the mesosphere and the thermosphere. There you can find artificial satellites.
The troposphere is the lowest layer, the one where we live It starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles).These layers are the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere. There are different layers of the atmosphere that are distinguished based on their temperature, chemical composition, movement, and density. In 1957, he set this boundary at 275,000 ft (83.82 km), or Von Karman line. Kármán also was the first person to calculate where the Earth’s atmosphere becomes too thin for airplanes to fly. His contribution in the fields of aeronautics and astronautics is immeasurable because of his theories of non-elastic buckling, stability of laminar flow, and many others.
He was born in Budapest, however, he did most of his research in the USA. He was into aeronautics and astronautics and spent his whole life working in these fields. In the 20th century, there was a Hungarian physicist Theodore von Kármán. What is the Karman line and the edge of space? In this article, you will learn what the Karman line is, which says right the same thing. Considering recent events of the first two tourists sent to space by the private companies, this line may be changed, which could lead to reviewing a few historical facts of who has been beyond the Earth and who has not. But the question about edge of space remains open even after their successful flights. In July 2021, Richard Branson and Jeff Bezos went to space.
