Why Nobody Can Legally Own the Moon and What Asteroid Mining Law Says About Space Sovereignty

On July 20, 1969, Neil Armstrong stepped onto the moon and planted an American flag. The United States did not own the moon. The flag was a gesture, not a deed. Two years before that landing, 107 nations had already signed the Outer Space Treaty of 1967, and its core clause is unambiguous: no nation can claim sovereignty over the moon, other planets, or any celestial body through use, occupation, or any other means. The moon belongs to no one. That is the legal baseline every space lawyer starts from.

The treaty frames outer space as the "province of all mankind", a phrase borrowed from maritime law's concept of the high seas. You can sail the ocean. You cannot own it. The same logic applies 384,400 kilometres above the Indian Ocean. What the treaty does not say, and what has become the central argument in space law for the past decade, is whether you can own what you extract from a place you are not allowed to own.

The asteroid belt between Mars and Jupiter contains an estimated 700 quintillion dollars' worth of metals, a figure so large it is essentially meaningless until someone actually retrieves any of it. The near-Earth asteroid 16 Psyche alone is thought to be composed largely of iron and nickel, with a metal content some researchers at NASA estimate could exceed the entire global iron reserves on Earth. These are not confirmed extraction-ready numbers, but the scale is real enough that several private companies began building business cases around it.

The legal opening they found is this: the Outer Space Treaty prohibits national appropriation of celestial bodies. It says nothing explicit about resources removed from those bodies. In 2015, the United States passed the Commercial Space Launch Competitiveness Act, which granted American citizens the right to own, sell, and transport resources extracted from asteroids and other space objects. Luxembourg followed in 2017 with its own space resources law. Neither country claimed ownership of any asteroid. They claimed that whatever their companies pull out of one is legally theirs.

Critics, including several international law scholars, argue this reading drives a vehicle through the treaty's intent. Supporters counter that the treaty was written in 1967, when asteroid mining was science fiction, and that resource extraction has always been legally distinct from territorial sovereignty, the same way fishing a tuna from international waters does not mean you own the Pacific.

No international body has settled this. The Moon Agreement of 1979 tried to close the loophole by declaring lunar and asteroid resources the "common heritage of mankind," which would require international sharing of any extracted wealth. Eighteen countries ratified it. The United States, Russia, and China did not. India has not ratified it either. Without the major spacefaring nations on board, the Moon Agreement is largely a document without enforcement.

What has filled the gap is a patchwork of national legislation and bilateral agreements. The Artemis Accords, initiated by NASA and signed by 43 countries as of early 2024, take the American position: extraction is permissible, and signatories agree to transparency and coordination without conceding that space resources are collectively owned. These accords are not a treaty in the binding international law sense. They are political commitments, and their legal weight depends entirely on how future courts and arbitration panels choose to interpret them.

The practical result is that asteroid mining law currently exists in a state of productive ambiguity: enough legal cover for companies to raise capital and plan missions, not enough settled law to resolve a serious dispute if one arises.

India signed the Artemis Accords in June 2023, a month before Chandrayaan-3 made its historic soft landing near the lunar south pole. That timing was not coincidental. The lunar south pole is believed to contain water ice in permanently shadowed craters, water that can be split into hydrogen and oxygen for rocket fuel, making it the most strategically valuable real estate on the moon for any nation planning sustained deep-space operations. India's presence there, even as a scientific mission, placed ISRO at the centre of the resource conversation.

India does not yet have domestic space resources legislation equivalent to the American or Luxembourg frameworks. The Indian Space Policy of 2023 opened the sector to private players through IN-SPACe, the regulatory body, and Gaganyaan will eventually give India crewed spaceflight capability. But the specific question of what an Indian company could legally claim if it extracted material from an asteroid or the lunar surface remains unanswered in Indian law. ISRO's scientific missions have been precise and ambitious, Mangalyaan reached Mars on its first attempt in 2014, Chandrayaan-3 succeeded where previous attempts failed, but the legal architecture for commercial extraction has not kept pace with the engineering.

The gap matters because asteroid mining is no longer a distant prospect. Companies like AstroForge in the United States have already launched test missions. Japan's JAXA brought back samples from the asteroid Ryugu via the Hayabusa2 mission in 2020. The question of who owns extracted asteroid material will be tested in a real commercial context before any global legal consensus forms.

The moon's surface is open to everyone and owned by no one, but the water ice beneath it, the metals inside an asteroid, and the fuel that could be refined from both are already being legislated over by nations writing their own rules in the absence of a shared one. India's position as a signatory to the Artemis Accords while lacking domestic extraction law means it has accepted a framework built by others, without yet defining what Indian space enterprise can claim within it. That is the real legal frontier, not the moon's surface, but the silence in the treaties that govern what lies underneath.
