The Karman Line

The Karman Line is the Border Separating the Earth’s Atmosphere from Space. It is Defined as Being 100km Above Sea Level and is Regarded as the Starting Point of Outer Space

The Fédération Aéronautique Internationale (FAI) is the world governing body for air sports and manages definitions regarding human spaceflight. But did you know the same organization also defined the Karman Line? The Karman Line, an imaginary boundary 100 kilometers above mean sea level, is a common definition of space. Once this 100 km line is …
