NASA’s Mars Sample Return mission has been cancelled, leaving ten sealed sample tubes on the Martian surface. Under Article VIII of the 1967 Outer Space Treaty, the United States retains jurisdiction and control over those objects, even without a retrieval plan. The Rescue and Return Agreement obligates any state that recovers a space object to return it to the launching state, but it does not clearly address the ownership of the material inside the tubes. U.S. domestic law treats extracted resources as property, while international law remains ambiguous, raising novel legal questions about liability and resource rights.
