Outer Space Treaty

The Outer Space Treaty is a multilateral treaty that forms the basis of international space law, negotiated and drafted under the auspices of the United Nations and opened for signature on January 27, 1967. The treaty prohibits nuclear weapons in space, limits the use of the Moon and other celestial bodies to peaceful purposes, and establishes that space shall be freely explored and used by all nations. It also precludes any country from claiming sovereignty over outer space or any celestial body, and does not ban all military activities in space, but rather focuses on regulating certain activities to prevent conflict. The treaty has been ratified by 115 countries and has provided many practical uses, serving as the most important link in the chain of international legal arrangements for space from the late 1950s to the mid-1980s.learn more on wikipedia
