The US is fast-tracking the development of lunar nuclear reactors to establish operational keep-out zones, which, while not legally binding, could effectively limit the lunar activities of other nations.
Building a base on the Moon is no easy feat. One would need to factor in transportation, manpower, and most importantly, a reliable source of energy. Hence, the best bet right now for a dependable lunar power source is nuclear energy.
NASA recently unveiled its plans to develop a lunar nuclear reactor by 2030. With missions to the Moon becoming increasingly frequent, these reactors are meant to provide 100 kilowatts of power to support lunar operations. This would reportedly be enough to run life support systems, communications, and mining equipment, sustaining long-term moon bases.
Yet, that’s not all that fuels NASA’s reactor timeline; Russia and China are playing a part too. Last year, both nations announced a joint effort to power the International Lunar Research Station, a collaborative project. To power this facility, they too announced plans to build and deploy a nuclear reactor by 2035.
On the surface, this might seem like a simple ‘who does it first?’ competition. Unfortunately, it is much deeper and complex than that.
In 1967, the world adopted the Outer Space Treaty, designed to keep outer space peaceful and for exploration to benefit all of humanity. In the context of this space race, one of the treaty’s clauses prohibited the claims of sovereignty on the Moon and other celestial bodies.
Additionally, it also contained an ambiguous article highlighting the avoidance of harm and disruption to the space activities of other nations.
Using this legal grey area, the US spearheaded the Artemis Accords, which saw over 50 signatories. The accords, which are non-binding international agreements, underscore ‘safety zones’, otherwise known as keep out zones. These are established to have limited interferences and activities by other parties, in efforts to protect security, economic interests, and operational safety.
