One of the most serious challenges is the lack of a cohesive regulatory framework for governing mining in outer space. While the 1967 Outer Space Treaty has been signed by all space-faring nations and is widely considered to be the constitutional document of outer space law, it has interpretation gaps.
Importantly, it determines that no nation can claim any celestial body (such as the moon) for itself — but it’s silent on whether derivative resources can be owned.
Earth lawyers contemplating space-mining projects are likely to look at four aspects: security of tenure, the fiscal regime, the bankability of the project and the project’s feasibility. Let’s break them down.
1. Security of tenure
In mining terms, security of tenure means having secure and stable rights throughout the mining cycle. The 1967 Outer Space Treaty is unclear on who would own any extracted resources, and interpretations vary.
So far, Luxembourg and the United States have enacted domestic legislation that favours the possibility of claiming extracted resources, thereby bringing security of tenure to space mining companies located in those jurisdictions.
2. The fiscal regime
This issue refers to the payment of taxes, royalties or the like. Here, the 1979 Moon Agreement comes into play. Only two space-faring countries are party to it: India and Australia.
There’s disagreement on the role that the Moon Agreement should play in outer space law. Some argue that it’s not pertinent to non-party countries; others point to its language and suggest parallels with the United Nations Convention on the Law of the Sea (UNCLOS). Both instruments refer to the “common heritage of mankind.”
UNCLOS has set up an international regulatory body, the International Seabed Authority, to licence mining in the deep sea on a royalty payment basis. Royalties are then to be distributed equitably among all nations on Earth. Some argue for a similar system to apply to outer space.
3. Bankability of the project
The third issue, project bankability, concerns the capacity of the project to attract funding.
To a large degree this will be determined by the prior two issues: security of tenure and the applicable fiscal regime. This again demonstrates the need for agreement on a clear legal framework before rushing into action.
4. Project feasibility
The last issue, has several facets. Technical feasibility is currently enjoying a lot of attention, with much research and development going into the advanced robotics and automated systems that would be needed for space mining operations.
Technological breakthroughs to date include the discovery of water crystals on the moon and on Mars, and the harnessing of 3D printing technology in space for manufacturing purposes. These make space mining more viable.
With the world’s two wealthiest people now both engaged in the space race — Jeff Bezos with Blue Origin and Elon Musk with SpaceX — we can expect rapid technological acceleration.
