The U.S. and China are accelerating efforts to establish permanent bases on the Moon to secure strategic resources and technological leadership [1, 2].

This competition marks a shift from scientific exploration to a race for territorial and resource dominance. Control over lunar assets could dictate the future of deep-space travel and provide critical materials not easily found on Earth.

Central to this race is the lunar south pole. Both nations are targeting this region because it is believed to contain water ice [1, 2]. Water is essential for sustaining human life and can be processed into rocket fuel, allowing the Moon to serve as a refueling station for missions further into the solar system.

Private companies are playing an increasingly central role in these ambitions. Firms such as SpaceX and Blue Origin are partnering with government agencies to develop the landing and transport infrastructure necessary for permanent habitation [1, 2]. These partnerships aim to reduce costs while increasing the frequency of lunar launches.

Beyond water, the superpowers are interested in rare resources like helium-3 [1, 2]. This isotope is scarce on Earth but potentially abundant on the lunar surface, where it could be used to power future nuclear fusion reactors.

The race has intensified throughout the 2020s, with both the U.S. and China targeting key milestones for the mid-2020s [1]. This timeline reflects a broader geopolitical struggle to demonstrate technological superiority through the colonization of space.

While international treaties govern the use of space, the push for permanent bases creates a gray area regarding resource ownership. The ability to occupy a specific site, particularly the resource-rich south pole, effectively grants a nation control over those materials [1, 2].

The United States and China are accelerating efforts to establish permanent bases on the Moon.

The transition from temporary lunar visits to permanent bases signals the beginning of an extraterrestrial economy. By focusing on the south pole's water ice and helium-3, the U.S. and China are treating the Moon as a strategic outpost. This competition suggests that future space law will be shaped more by 'de facto' occupation and resource extraction than by existing international agreements.
