Nearly one hundred countries, including the world’s spacefaring nations, have formally agreed upon the principles set out in the 1967 “Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies,” more commonly known as the UN Outer Space Treaty.
