Where Does Space Actually Begin?

Brian Kezer obtained a degree in computer science from George Washington University in Washington DC. Away from his professional life, he blogs anonymously. On his anonymous blog, Brian Kezer wrote about outer space.

Among scientists and various government organizations, there is some controversy about where outer space begins. Generally, experts believe that space begins where orbital forces are more needful than aerodynamic forces. This is the point where only the atmosphere is insufficient to support a suborbital flying craft. Over the years, it has not been very easy to decipher the exact altitude at which this happens.

Theodore Kármán, a Hungarian scientist, determined this point to be at 50 miles or 80 kilometers above sea level. The National Oceanic and Atmospheric Administration (NOAA) says that the Kármán line is an imaginary boundary about 100 kilometers above sea level. Fédération Aéronautique Internationale (FAI) also puts space at 100 kilometers or 62 miles above sea level. However, the Federal Aviation Administration, NASA, and even the NOAA mostly use 50 miles/80 kilometers as the outer space boundary.

The Air Force grants astronaut wings to officials who fly higher than this point. Dissenting further from the general agreements, NASA Mission Control places space at 76 miles/122 kilometers above sea level because, at this point, atmospheric drag is detectable.
