The United States and China are locked in a high-stakes race to the Moon’s south pole, with both nations targeting water ice as the key to sustaining future lunar settlements. China’s Chang’e‑7 mission, launching in August 2026, is widely seen as more technically viable than NASA’s delayed 2028 timeline, giving Beijing a potential edge in landing astronauts by 2030.

The United States and China are entering a new phase of competition in space exploration, with the Moon’s south pole emerging as the focal point. Scientists believe this region contains water ice, a resource that could be vital for sustaining extra-terrestrial settlements by providing drinking water, oxygen, and rocket fuel. Both nations are accelerating robotic missions to this treacherous terrain, hoping to secure strategic advantage.

China has already demonstrated significant progress. Following the success of Chang’e‑6 in 2024, which returned samples from the Moon’s far side, Beijing is now preparing to launch the Chang’e‑7 mission in August 2026.

This ambitious mission will deploy four robotic vehicles — an orbiter, lander, rover, and a mobile hopper — to Shackleton Crater at the lunar south pole. The hopper is designed to leap into permanently shadowed regions where temperatures plunge to −173°C, enabling direct analysis of water ice deposits that may have been preserved since the solar system’s formation. The mission carries 21 scientific payloads, including six international instruments, underscoring China’s growing role as a global space power.

In contrast, the United States is relying heavily on private companies to deliver its lunar ambitions. NASA has funded Astrobotic Technology to develop the Griffin lander, scheduled for delivery to the lunar south pole in late 2026.

This mission will attempt to navigate the pole’s hazardous terrain, but the US will not be able to conduct drilling and water ice analysis until at least 2027. NASA is also contributing its Neutron Spectrometer System to the LUPEX mission led by Japan and India, planned for 2028, which will further investigate hydrogen concentrations beneath the lunar surface.

The strategic importance of water ice cannot be overstated. If successfully located in sufficient quantities, it could dramatically reduce the cost and time required to transport water from Earth.

This would facilitate the establishment of a permanent human base on the Moon, enabling long-term activities and serving as a refuelling station for deeper missions to Mars and beyond.

Tang Yuhua, deputy chief designer of Chang’e‑7, emphasised in a 2025 interview that lunar water ice could be electrolysed into hydrogen and oxygen, transforming the Moon into a launchpad for interplanetary exploration.

China’s broader ambitions are clear. President Xi Jinping has described space exploration as an “eternal dream,” and Beijing aims to become the second nation after the US to land humans on the Moon.

Its target of a crewed lunar landing by 2030 appears increasingly realistic given its recent successes in navigation, propulsion, and sensing technologies. The country also plans to establish a permanent lunar settlement by 2040, supported by its Tiangong space station and extensive investment in space infrastructure.

The United States, meanwhile, faces mounting challenges. NASA’s proposed timeline to land astronauts by 2028 has been repeatedly delayed due to engineering and technological hurdles. Lawmakers are concerned about the shifting schedule and the difficulty of landing near the uncharted south pole. Experts now argue that China’s path to a Moon landing by 2030 is more viable, raising geopolitical concerns in Washington about losing leadership in space exploration.

The race to the lunar south pole is not merely scientific but deeply strategic. Control over water ice resources could determine which nation establishes the first sustainable human presence on the Moon, shaping the future of exploration and geopolitical influence in space.
