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 per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up.
Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
The United States Air Force uses 50 nautical miles (300,000 feet) to award astronaut wings. [1] No successful space dives (above 100 km) have been completed to date. In 1959 Joseph Kittinger accomplished a jump from 74,700 feet (22.8 km); he then set a long-standing record in 1960 when he jumped from 102,800 feet (31.3 km).
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.

Pictures from the International Space Station do not disappoint, ... the view 250 miles above Earth does not disappoint. Here are the best photos of 2024 from the space station.
Missions which were intended to reach space but which failed to do so are listed in bold. Missions between 50 miles (80.45 km) and 100 km (62 mi), which satisfy the US Military definition of space(50 Miles), but not the NASA or Internationally recognized Karman Line definition (100 KM) are listed in italics.
Orbit of AMC-8 satellite around the Earth in 2000, transferring from a geostationary transfer orbit to a geostationary orbit. An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit.
