For decades, the Moon’s south pole was viewed as one of the most hostile environments in the Solar System—a frozen landscape where temperatures plunge below −170°C, sunlight disappears for nearly 14 Earth days at a time, and survival depends on overcoming one relentless challenge: energy. Today, that region has become the center of an international race, and China’s ambitions are attracting worldwide attention.
The greatest obstacle to a permanent lunar presence is not transportation or even low gravity—it’s surviving the two-week-long lunar night. Solar panels, while effective during daylight, cannot generate electricity during this prolonged darkness, forcing missions to rely on limited batteries or other backup systems. Any permanent settlement must solve this problem before anything else.
China’s long-term plans for the International Lunar Research Station (ILRS) include studying advanced nuclear power systems capable of providing continuous electricity regardless of whether the Sun is shining. While no large lunar reactor has yet been deployed, Chinese researchers have publicly discussed developing compact nuclear reactors as one possible solution for sustaining future lunar bases. Similar concepts are also being explored by NASA and other space agencies, reflecting a broader recognition that reliable power will be essential for permanent operations on the Moon.
Continuous power would transform what is possible. Instead of shutting down every lunar night, scientific instruments, communication systems, mining equipment, and life-support technologies could operate around the clock. Reliable energy is not simply about keeping the lights on—it is the foundation for long-term exploration, resource extraction, and future human habitation.
Power, however, is only one piece of the puzzle. China is also developing technologies that would allow future bases to be built using lunar regolith—the fine layer of rock and dust covering the Moon’s surface. Rather than transporting enormous quantities of concrete, steel, and construction materials from Earth at enormous cost, engineers are investigating methods to convert local lunar soil into building materials through high-temperature sintering and 3D-printing technologies.
One of the major demonstrations planned for the Chang’e-8 mission is to test these forms of in-situ resource utilization (ISRU). The goal is straightforward: use the Moon’s own materials to manufacture landing pads, protective walls, roads, and eventually habitats. Robotic construction systems would perform much of this work before astronauts arrive, reducing both cost and risk.
This approach is not unique to China. NASA’s Artemis program and the European Space Agency are pursuing similar concepts because launching construction materials from Earth remains one of the most expensive aspects of any lunar mission. The ability to “build with lunar soil” is widely considered one of the key technologies that could make permanent settlements economically feasible.
The Moon’s south pole has attracted particular interest because permanently shadowed craters are believed to contain significant deposits of water ice. That ice could potentially provide drinking water, breathable oxygen, and hydrogen for rocket fuel. Combined with near-continuous sunlight on nearby ridge lines, the region represents one of the most strategically valuable locations beyond Earth.
China’s broader vision is to gradually expand robotic exploration into a permanently occupied scientific research station during the 2030s, working with international partners participating in the ILRS initiative. Rather than a single building, the concept envisions a network of landers, robotic systems, communications infrastructure, power generation, and eventually human habitats connected into one integrated lunar research complex.
Although headlines often portray this effort as a race to “control the Moon,” international space activities remain governed by treaties such as the Outer Space Treaty, which prohibits national sovereignty over celestial bodies. In practice, however, whichever nations establish reliable infrastructure first will likely gain important scientific, technological, and operational advantages that shape humanity’s future presence beyond Earth.
China’s lunar program therefore represents something larger than a single mission. It reflects the beginning of an era in which the Moon is no longer viewed as a place to visit briefly, but as a destination where humans may one day live, work, and conduct scientific research for extended periods. Whether these ambitious plans unfold exactly as envisioned remains to be seen, but one thing is already clear: the next chapter of lunar exploration is focused not on leaving footprints—but on building the infrastructure for a permanent human presence.
