Space Altitude
The framework for international space law was established by the outer space treaty which entered into force on 10 october 1967.
Space altitude. It is the largest artificial object in space and the largest satellite in low earth orbit regularly visible to the naked eyefrom earth s surface. This is known as the karman line. From that perspective the international space station which orbits at only 330 435 kilometers above the earth isn t even worthy of its name.
Other organizations do not use this definition. Crewed space missions are mostly at 400 km 250 mi altitude and below where air drag helps clear zones of fragments. Spacex ceo elon musk says that the first high altitude starship prototype known as sn8 just passed cryo proof testing in south texas potentially setting the ship up for a 15 km 9.
The karman line lies at an altitude of 100 kilometres 62 mi above the earth s sea level. 100 km or about 62 miles above sea level is the commonly used altitude for the beginning of space. The united states uses 80 km or 50 miles above sea level as.
The upper atmosphere is not a fixed density at any particular orbital altitude. High altitude and low pressure. 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.
For most of the last decade as astronauts and cosmonauts orbited the earth aboard the international space station they were circling the globe at an altitude of approximately 220 statute miles or about 350 kilometers. High altitude is sometimes defined to begin at 2 400 meters 8 000 ft above sea level. The kármán line is the boundary between the earth s atmosphere and outer space.
The thermosphere and exosphere along with the higher parts of the mesosphere are regions of the atmosphere that are conventionally defined as space. It varies as a result of atmospheric tides and expands or contracts over longer time periods as a result of space weather. It maintains an orbitwith an average altitude of 400 kilometres 250 mi by means of reboost manoeuvres using the engines of the zvezdaservice module or visiting spacecraft.
