Space Law: Is Asteroid Mining Legal?
Can a private company claim ownership of an asteroid based on sending a probe
out to it? Can it at least get exclusive mining rights? Would it own the gold,
platinum or other materials mined from the asteroid?
Last week, a new private company,
Planetary Resources
announced an ambitious plan to
prospect
for and eventually mine near-Earth asteroids. Backed in part by Google execs
Larry Page and Eric Schmidt, this venture has stirred the pot once again on the
question of outer space property rights.
Understanding the legality of asteroid mining starts with the 1967
Outer Space Treaty. Some might argue the treaty bans all space
property rights, citing Article II:
Outer space, including the moon and other celestial bodies, is not subject to
national appropriation by claim of sovereignty, by means of use or occupation,
or by any other means.
Others have argued that because Article II only applies to nations, individuals are free
to claim chunks of the solar system. But as
we’ve
noted before, the treaty also requires nations to ensure their citizens
comply with the other provisions of the Outer Space Treaty — including a
prohibition against sovereign claims of property rights. So neither nations nor
individuals can appropriate territory in space. But what about asteroid
mining?
While Article II clearly bans “appropriation,” other provisions actually
support property rights. The treaty makes clear that both the exploration and
use of outer space shall be free of restraint and discrimination, and that there
will be free access to all parts of space. It also states that the use of
equipment and facilities necessary for peaceful activities is fine. And anything
launched into (or built in) space remains the private property of its owner.
To make sense of the Treaty, we must turn to customary international law —
how nations have interpreted what these treaty provisions mean in their
dealings, both internally, and with other nations. These other sources of
international law are critical because the Outer Space Treaty itself is at best
confusing and, at worst, internally inconsistent on space property rights.
Blanket claims to celestial bodies have been attempted for millennia, yet
none has been recognized by customary law. The only court case we have in this
respect arose when
Greg Nemitz, a space activist, filed a claim for the asteroid
Eros with an online database known as the Archimedes Institute, and then sent
NASA a bill for parking fees when NASA landed the NEAR-Shoemaker probe on Eros
in 2001. The U.S. 9th Circuit Court of Appeals dismissed the suit because Nemitz
was unable to prove actual ownership rights for Eros.
While Nemitz failed, customary international law has essentially recognized
property rights based on possession — which, as the old saying goes, is
nine-tenths of the law. Satellite orbits, for instance, are allocated by the
International Telecommunications Union. Strictly speaking, they are not “owned”
by the assignee, but can be renewed on a regular basis, and can be leased to
other parties. This and Outer Space Treaty’s recognition of property rights for
satellites are the basis for the more than $300-billion-per-year private
satellite industry.
Similarly, asteroid mining will depend on customary international law
established by the 1960s moon race between the U.S. and USSR. The six Apollo
landings brought back 842 pounds of lunar material. NASA has strictly controlled
use of the material, and less than 10 percent has ever been experimented on.
NASA itself claims (.pdf) that the lunar samples are “a
limited national resource, a future heritage, and [requires] that samples be
released only for approved applications in research, education, and public
display.” The United States government has vigorously prosecuted anyone thought
to have improperly obtained any such samples. Yet NASA exchanged some of these
samples with the Soviet Union, which drew from the approximately 300 grams of
lunar material brought back by three Soviet Luna robotic sample return
missions.
Under any definition of ownership, the United States clearly owns the Apollo
lunar samples. Any entity that can claim something as an exclusive resource,
control its transport and distribution, and can exchange it for something else
of value (in this case, other lunar samples), clearly owns that object. Russian
lunar samples have been re-sold by private individuals, establishing that
portions of a celestial body can be subject to ownership if they are removed
from that celestial body — whether by governments or private parties — even if
the celestial bodies themselves are not subject to appropriation.
This is the single most important legal precedent for property rights in
space, and should provide great comfort to those who wish to exploit the
resources of outer space. It is also consistent with many commentators, who
allege that the Outer Space Treaty’s prohibition on “appropriation” relates only
to entire celestial bodies as they exist “in nature,” and that both individuals
and nations can claim ownership of resources extracted from celestial bodies.
The only real question, then, is the extent of this ownership: Can an entire
asteroid be claimed if it is being mined?
Under the Outer Space Treaty, if a company is mining an asteroid, no other
entity could come along and start mining on the other side if doing so could
interfere with the first set of miners. If the asteroid were large enough to
accommodate two independent mining operations, both could likely proceed, each
gaining ownership of whatever material they extract. Thus, customary
international law already gives would-be asteroid miners a sound basis for their
business model.
But what if a mining company captured an asteroid, changing its orbit to
bring it closer to Earth and thus make return of extracted materials easier?
Would the entire asteroid belong to the mining company because the asteroid, as
a whole, was “extracted” from its “natural” orbit — becoming more like a single
rock or an artificial satellite than a moon or a planet?
This question is too far in the future to answer. But the day that question
arrives, we can all pop the champagne corks to celebrate: Mankind will have
become a truly spacefaring species. We will have taken the first steps toward
bringing the nearly limitless resources of space into the economic sphere of
humanity.
