<P> Outer space does not begin at a definite altitude above the Earth 's surface . 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 . The framework for international space law was established by the Outer Space Treaty , which entered into force on 10 October 1967 . This treaty precludes any claims of national sovereignty and permits all states to freely explore outer space . Despite the drafting of UN resolutions for the peaceful uses of outer space , anti-satellite weapons have been tested in Earth orbit . </P>
