The current international space law framework does not provide clarity on the legality of outer space resource mining, its utilisation and ownership. However, over the past few years, there has been a growing interest between both the Government and private industry to explore this new avenue for Research and Development and commercial purposes. In order to address and curtail the effect of international ambiguity concerning this subject matter, some nations have implemented national legislations permitting outer space resource mining and related aspects. But does national legislation override international treaties and principles? Owning to the economic, societal and legal implications, this paper analyses the legality of outer space resource mining under the current framework of international space law, various national legislations vis-a-vis the international maritime law, and examines whether the Artemis Accords, disguised as soft law, is a step towards internationally validating and reinforcing the space resource extraction, utilisation and addresses its implications.
