The legal framework reconciling private property rights over extracted lunar ice/minerals under the Artemis Accords with Article II of the 1967 Outer Space Treaty.
Article II of the 1967 Outer Space Treaty establishes that outer space, including the Moon and celestial bodies, is not subject to national appropriation by claim of sovereignty. However, the U.S. Commercial Space Launch Competitiveness Act of 2015 (51 U.S.C. § 51303) and Section 10 of the bilateral Artemis Accords recognize that private commercial entities retain property ownership over in-situ resources (water ice, regolith) once extracted.
International dispute between Artemis Accord signatories (viewing extraction as akin to deep-sea fishing rights in international waters) and non-signatories (arguing commercial extraction violates non-appropriation under Article II).
