province of all mankind, Reaffirming further the will of all States that the exploration and use of outer space, including the Moon and other celestial bodies, shall be for peaceful purposes, Recalling that the States parties to the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, have
