So, the U.S. flag was not a manifestation of claiming sovereignty, but of honoring the U.S. taxpayers and engineers who made Armstrong, Aldrin, and third astronaut Michael Collins’ mission possible. The two men carried a plaque that they “came in peace for all mankind,” and of course Neil’s famous words echoed the same sentiment: his “small step for man” was not a “giant leap” for the United States, but “for mankind.” Furthermore, the United States and NASA lived up to their commitment by sharing the moon rocks and other samples of soil from the lunar surface with the rest of the world, whether by giving them away to foreign governments or by allowing scientists from all over the globe to access them for scientific analysis and discussion. In the midst of the Cold War, this even included scientists from the Soviet Union.

Case closed, no need for space lawyers anymore then? No need for me to prepare University of Nebraska-Lincoln’s space law students for further discussions and disputes on the lunar law, right?

No space lawyers needed?

Not so fast. While the legal status of the Moon as a “global commons” accessible to all countries on peaceful missions did not meet any substantial resistance or challenge, the Outer Space Treaty left further details unsettled. Contrary to the very optimistic assumptions made at the time, so far humankind has not returned to the moon since 1972, making lunar land rights largely theoretical.

That is, until a few years ago when several new plans were hatched to go back to the moon. In addition at least two U.S. companies, Planetary Resources and Deep Space Industries, which have serious financial backing, have started targeting asteroids for the purpose of mining their mineral resources. Geek note: Under the aforementioned Outer Space Treaty, the moon and other celestial bodies such as asteroids, legally speaking, belong in the same basket. None of them can become the “territory” of one sovereign state or another.

The very fundamental prohibition under the Outer Space Treaty to acquire new state territory, by planting a flag or by any other means, failed to address the commercial exploitation of natural resources on the moon and other celestial bodies. This is a major debate currently raging in the international community, with no unequivocally accepted solution in sight yet. Roughly, there are two general interpretations possible.

So you want to mine an asteroid?

Countries such as the United States and Luxembourg (as the gateway to the European Union) agree that the moon and asteroids are “global commons,” which means that each country allows its private entrepreneurs, as long as duly licensed and in compliance with other relevant rules of space law, to go out there and extract what they can, to try and make money with it. It’s a bit like the law of the high seas, which are not under the control of an individual country, but completely open to duly licensed law-abiding fishing operations from any country’s citizens and companies. Then, once the fish is in their nets, it is legally theirs to sell.
