The Moon Agreement is an international treaty that aims to govern the exploration and use of the Moon and other celestial bodies. Adopted in 1979, it emphasizes that the Moon and its resources are the common heritage of mankind, meaning that no single country can claim ownership over them. The agreement encourages cooperation among nations in the peaceful exploration of outer space. As of now, only a few countries have ratified the Moon Agreement, including Austria, Belgium, and Mexico. Major space-faring nations like the United States and Russia have not signed it, which limits its effectiveness. The treaty seeks to promote sustainable practices in space exploration and ensure that benefits are shared globally.
