Outer Space Treaty Ratified in 1967, Establishing Principles for Space Exploration and Use
On October 10, 1967, the international Outer Space Treaty was ratified, establishing a foundational set of rules for how countries can explore and use outer space. This treaty, formally known as the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, dictates that the exploration and use of outer space must be carried out for the benefit and in the interests of all countries, and shall be the province of all mankind. A key provision of the treaty is that no nation can claim territory in outer space. Furthermore, it mandates that celestial bodies, such as the Moon, must be used exclusively for peaceful purposes, explicitly prohibiting the establishment of military bases, installations, fortifications, testing of weapons, or military maneuvers on them. Over 100 countries have ratified this treaty, making it a cornerstone of modern space law.
