The Kármán line is a hypothetical boundary located 100 km above sea level, designating the end of the earth’s atmosphere and the beginning of outer space. The Karman Line is the height which is commonly accepted as the ‘start of space’. A vortex street will form only at a certain range of flow velocities, specified by a range of Reynolds numbers (Re), typically above a limiting Re value of about 90.

In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight. He suggested its creation for the clear-cut separation of the fields of aeronautics and astronautics. There is a sudden increase in temperature of the atmosphere and solar radiation just below the line. He remained in Germany until 1930, with a three-year interruption to serve in the Austro-Hungarian army. It is an imaginary boundary, that gives a rough, easy to remember height for the border between Earth and space of 100km (although according to Jonathan McDowell, that imaginary border may be wildly incorrect, and need to be revised inwards to 85km). There is no discrete boundary between the Earth's atmosphere and space as the atmosphere gradually attenuates with increasing altitude. The Kármán line is the altitude where space begins.

Kármán Line is a business performance consultancy that helps individuals and organisations to think big, set aspiring goals and develop focused plans to help them get there. Aerospace pioneer Theodore von Kármán argued that the point where orbital dynamics forces exceed aerodynamic forces is a sensible place to set the limit—now known as the Kármán line (see figure 1, in which k = 0 defines the Kármán line height). Musician/Band. The boundaries between the Earth's surface and outer space, at the Kármán line, 100 km (62 mi) and exosphere at 690 km (430 mi) The problem is that the atmosphere density $\rho(r)$ is a function of height, and it varies in a non-trivial way because it depends on the temperature and the temperature varies in a non-trivial way with height.

By international convention, the Kármán line marks the beginning of space where human travelers are considered ASTRONAUTS! The Kármán line idea originates with Theodore von Kármán, a Hungarian-American physicist who calculated that above around 100 km in the atmosphere, the air becomes so thin that a craft must travel at greater than orbital speed to stay aloft. The Kármán line lies at an altitude of 100 kilometres (62 mi) above the Earth's sea level, and is commonly used to define the boundary between the Earth's atmosphere and outer space. This definition is accepted by the Fédération Aéronautique Internationale (FAI), which is an international standard setting and record-keeping body for aeronautics and astronautics. An aircraft at this altitude would have to travel faster than orbital velocity to obtain enough lift to support itself. In theory, the Kármán line is the altitude where the velocity needed to keep a typical aircraft aloft equals the orbital velocity of an object at that same altitude. It commonly represents the border between the Earth's atmosphere and outer space.

The Kármán line, or Karman line, represents the boundary between Earth’s atmosphere and outer space. This is too thin for aeronautic purposes, and as such, activity above 100km is demarcated as astronautic rather than aeronautic. It is 100 km high. At this altitude, a conventional plane would need to reach orbital velocity or risk falling back to Earth. As I understand it, the upper heterosphere, at a distance greater than 100 km (the limit of Earth’s atmosphere, the Kármán line) and up to 120 km altitude, is composed almost exclusively of hydrogen.
