At What Altitude Does Space Begin

Mcdowell argues that the karman line used today is as a result of decades of misinterpretation of information that does not account for orbital data.

At what altitude does space begin. Nasa and the fédération aéronautique internationale the organization for international aeronautical and astronautical record keeping recognize this line as the point where space begins if. 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. Signed the fai agreement establishing 100 kilometers as the definition of where space begins but it still awards astronaut status to anyone who flies above 80.

The widely accepted boundary between the atmosphere and space is 62 miles above the sea level but in 2018 astrophysicist jonathan mcdowell suggested that the edge of space should be 12 miles lower. Today the commonly agreed upon definition of where space begins is around 100 kilometers 62 miles. There is no firm boundary where space begins.

100 km or about 62 miles above sea level is the commonly used altitude for the beginning of space. The framework for international space law was established by the outer space treaty which entered into force on 10 october 1967. The united states uses 80 km or 50 miles above sea level as.

This is known as the karman line. How high do you have to go to be in space officially. However the kármán line at 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.

Anyone who flies above 80 km 50 miles in altitude is usually considered an astronaut according to nasa. Although there is no definite boundary where space starts there is a limit and if you crossed it you would have entered space at least officially. 330 000 feet above earth s mean sea level.
