This map layer shows where the Outer Space Treaty has been ratified.
The Outer Space Treaty (in full: The Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and other Celestial Bodies) entered into force in 1967. The treaty, which Germany ratified in 1971, laid the foundation for international space law. It requires parties to use space and the moon exclusively for civil purposes and ban military uses or military exercises in space. The treaty also forbids the occupation of a celestial body by an individual state. If damage occurs as a result of placing objects into space, the responsible state must bear liability, although incidents of this kind have, to date, been exceptions.
