1. Karman line

   The Kármán line (or von Kármán line ) is an attempt to define a boundary between Earth's atmosphere and outer space, and offers a specific definition set by the Fédération aéronautique internationale (FAI), an international record-keeping body for aeronautics. Defining the edge of space is important for legal and regulatory purposes since aircraft and spacecraft fall under different jurisdictions and are subject to different treaties. International law does not define the edge of space, or the limit of national airspace.The FAI defines the Kármán line as space beginning 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above Earth's mean sea level. This number is well above the altitude reachable by a conventional airplane and is roughly where satellites, even on very eccentric trajectories, will decay before completing a single orbit. While experts disagree on exactly where the atmosphere ends and space begins, most regulatory agencies (including the United Nations) accept the FAI Kármán line definition or something close to it. As defined by the FAI, the Kármán line was established in the 1960s. Various countries and entities define space's boundary differently for various purposes.The Kármán line is named after Theodore von Kármán (1881–1963), a Hungarian-American engineer and physicist who was active in aeronautics and astronautics. In 1957, he was the first person to attempt to calculate an altitude limit for airplanes.

1. Kármán line

   The Kármán line, or Karman line, lies at an altitude of 100 kilometres above the Earth's sea level, and commonly represents the boundary between the Earth's atmosphere and outer space. This definition is accepted by the Fédération Aéronautique Internationale, which is an international standard-setting and record-keeping body for aeronautics and astronautics. The line is named after Theodore von Kármán, a Hungarian-American engineer and physicist. He was active primarily in aeronautics and astronautics. He was the first to calculate that around this altitude, the atmosphere becomes too thin to support aeronautical flight, because a vehicle at this altitude would have to travel faster than orbital velocity to derive sufficient aerodynamic lift to support itself. There is an abrupt increase in atmospheric temperature and interaction with solar radiation just below the line, which places the line within the greater thermosphere.

1. Jeff Bezos:

   We've always had as our mission that we wanted to fly above the Karman Line, because we didn't want there to be any asterisks next to your name about whether you're an astronaut or not, that's something [ Virgin Galactic is ] going to have to address, in my opinion.
