The global governance of space activities is inherently international. Given the status of outer space as a global commons, and in light of the explicit applicability of international law through Articles I para. 2 and III of the Outer Space Treaty (OST), it can be reasonably concluded that the rules governing celestial bodies—as well as interplanetary space—are international in nature. Accordingly, all activities in outer space, whether carried out by public or private actors, are subject to international law. The same legal framework will, of course, apply to future activities related to the use and exploitation of space mineral resources.
