Outer Space Commencement is a mystery to almost everyone as there have been probing studies on this but scientists are still in a process of searching the answer. The space commences where the atmosphere ends, and that might be correct. The scientists state much of the origin of space closer to home stationing the boundary of space within the limitations of the atmosphere.
The extensively acquired definition of the “edge of space” is 100 kilometers above the Earth’s surface. This altitude is called Kármán Line, named for Hungarian physicist and engineer Theodore von Kármán, who resolved that aeronautics would no longer function at that altitude. Paul Newman, Chief Scientist for Earth Sciences at NASA Goddard Space Flight Center elucidates that the Kármán line is defined as the altitude where the speed is not fast enough to engender lift for an aircraft. Apart from the aeronautics, there lies another variation below and above the Kármán Line. Below 100 kilometers gases are mingled together by tumultuous motions. Therefore nitrogen is about 78%, and oxygen is about 21%. Above 100 kilometers gases begin to separate out due to the lack of the gravity. This refers to altitude of separation as the homopause, because everything below is equally mingled.
This 100 kilometer/62 mile altitude is spelt out by Fédération Aéronautique Internationale (FAI), the international governing body of air sports, which embodies everything from ballooning to human spaceflight, as the beginning of space. Dr. Terry D. Oswalt, Chair of the Department of Physical Sciences at Embry-Riddle Aeronautical University said that the commercial space industry is harboring this as a goal for their tourist flights too.
