    en.wikipedia.org/wiki/Kármán_line

    In the final chapter of his autobiography, Kármán addresses the issue of the edge of outer space: Where space begins ... can actually be determined by the speed of the space vehicle and its altitude above the Earth. Consider, for instance, the record flight of Captain Iven Carl Kincheloe Jr. in an X-2 rocket plane. Kincheloe flew 2000 miles ...

    The Kármán line, an altitude of 100 km (62 mi) above sea level, [9] [10] is conventionally used as the start of outer space in space treaties and for aerospace records keeping. Certain portions of the upper stratosphere and the mesosphere are sometimes referred to as "near space".

    Outer space does not begin at a definite altitude above Earth's surface. The Kármán line , an altitude of 100 km (62 mi) above sea level , is conventionally used as the start of outer space in space treaties and for aerospace records keeping.

  5. Low Earth orbit - Wikipedia

    en.wikipedia.org/wiki/Low_Earth_orbit

    A view from the International Space Station in a low Earth orbit (LEO) at about 400 km (250 mi), with yellow-green airglow visible at Earth's horizon, where roughly at an altitude of 100 km (62 mi) the boundary between Earth and outer space lies and flying speeds reach orbital velocities.

    The lunar DRO is a high lunar orbit with a radius of approximately 61,500 km. [24] This was proposed [by whom?] in 2017 as a possible orbit for the Lunar Gateway space station, outside Earth-Moon L1 and L2. [20] Decaying orbit: A decaying orbit is an orbit

    en.wikipedia.org/wiki/Airspace

    The Fédération Aéronautique Internationale has established the Kármán line—at an altitude of 100 km (62 mi)—as the boundary between the Earth's atmosphere and outer space. [8] However, descending Space Shuttles flew closer than 80 km (50 mi) over other nations, such as Canada, without requesting permission first. [9]

  8. List of spaceflight records - Wikipedia

    en.wikipedia.org/wiki/List_of_spaceflight_records

    The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.

    MW 18014 was a German A-4 test rocket [nb 1] launched on 20 June 1944, [1] [2] [3] at the Peenemünde Army Research Center in Peenemünde.It was the first human-made object to reach outer space, attaining an apogee of 176 kilometres (109 mi), well above the Kármán line that was established later as the lowest altitude of space.
