Earth's atmosphere photographed from the International Space Station.The orange and green line of airglow is at roughly the altitude of the Kármán line. [1]The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space; it is widely but not universally accepted.
By definition, a sub-orbital spaceflight reaches an altitude higher than 100 km (62 mi) above sea level. This altitude, known as the Kármán line, was chosen by the Fédération Aéronautique Internationale because it is roughly the point where a vehicle flying fast enough to support itself with aerodynamic lift from the Earth's atmosphere ...
Transatmospheric orbit (TAO): geocentric orbits with an apogee above 100 km and perigee that intersects with the defined atmosphere. [4] Very low Earth orbit (VLEO) is defined as altitudes between approximately 100 - 450 km above Earth’s surface. [5] [6] Low Earth orbit (LEO): geocentric orbits with altitudes below 2,000 km (1,200 mi). [7]
The V-2 No. 13 [1] was a modified V-2 rocket that became the first object to take a photograph of the Earth from outer space. [ 2 ] [ 3 ] Launched on 24 October 1946, [ 4 ] at the White Sands Missile Range in White Sands, New Mexico , the rocket reached a maximum altitude of 65 miles (105 km).
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.

Elevation or altitude above sea level is a standard measurement for: Geographic locations such as towns, mountains and other landmarks. The top of buildings and other structures. Mining infrastructure, particularly underground. Flying objects such as airplanes or helicopters below a Transition Altitude defined by local regulations. [2]
