The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) is a conventional definition of the edge of space.It is not universally accepted. The international record-keeping body FAI (Fédération aéronautique internationale) defines the Kármán line at an altitude of 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above mean sea level.
Kármán line, boundary separating Earth’s atmosphere and outer space. The line is neither sharp nor well defined but is often taken to encircle Earth at an altitude between 80 to 100 km (50 to 62 miles) above mean sea level. The line originated with Hungarian American engineer and physicist Theodore.
Dec 20, 2018 · In the 1900s, Hungarian physicist Theodore von Kármán determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. Today, though, the Kármán line is set at what ...
Nov 27, 2023 · The Kármán line is more of a “folk theorem,” according to spaceflight historian Jonathan McDowell, who published a paper on the subject in the journal Acta Astronautica in 2018.
Nov 14, 2022 · The Kármán line is a boundary 62 miles (100 kilometers) above mean sea level that borders Earth's atmosphere and the beginning of space. However, defining exactly where space begins can be ...

May 5, 2021 · The Kármán line is based on physical reality in the sense that it roughly marks the altitude where traditional aircraft can no longer effectively fly. Anything traveling above the Kármán line needs a propulsion system that doesn’t rely on lift generated by Earth’s atmosphere — the air is simply too thin that high up.
