Treaty and its Protocol on Environmental Protection implement the articles of these agreements, and decisions taken under them, through national laws. These laws generally apply only to their own citizens, wherever they are in Antarctica, and serve to enforce the consensus decisions of the consultative parties: about which activities are acceptable, which areas require permits to enter, what processes of environmental impact assessment must precede activities, and so on. The Antarctic Treaty is often considered to represent an example of the common heritage of mankind principle. Outer space Outer space is generally regarded as an international zone insofar as it falls outside the national jurisdiction of any state. Article II of the Outer Space Treaty expressly forbids states from claiming celestial bodies such as the Moon or a planet as their own territory, whether by declaration, occupation, or "any other means". However, the state that launches a space object, such as a satellite or space station, retains jurisdiction and control over that object; by extension, a state is also liable for damages caused by its space object. Additionally, the treaty limits the use of the Moon and other celestial bodies to peaceful purposes and prohibits their use for testing weapons of any kind, conducting military manoeuvres, or establishing military bases, installations, and fortifications (Article IV). However, the treaty does not prohibit the placement of conventional weapons in orbit, and thus some highly destructive attack tactics, such as kinetic bombardment, are still potentially allowable. Furthermore, the treaty explicitly allows the use of military personnel and resources to support peaceful uses of space, mirroring the Antarctic Treaty's position on military deployment in that continent. While most satellites and space stations are administered by the state that deployed them, the International Space Station is governed by an international framework established by the Agreement Concerning Cooperation on the Civil International Space Station. Under the agreement, each state is responsible for any liability associated with the components it contributes to the station and for the management of their programmes and utilisation of the station. Furthermore, each participating state exercises criminal jurisdiction over its personnel on the station except where the victim of a crime is a national of another participating state and the perpetrator's state of nationality does not prosecute the offence.
