Last week, China’s space exploration efforts reached a remarkable milestone with the successful return of samples from the far side of the moon. This event not only emphasizes China’s advancements in space exploration but also ignites a new phase of competition with the U.S. and its allies to establish strategic outposts on the moon’s south pole.
The Chang’e 6 mission concluded its 53-day journey with a successful landing in Inner Mongolia’s grasslands on June 25 at 2:07 A.M. EDT. The spacecraft brought back approximately two kilograms of rock and soil collected from the South Pole–Aitken (SPA) Basin, one of the largest and oldest craters in the solar system. These samples could provide crucial insights into the moon’s geological history, particularly why the far side of the moon lacks the craters and lava plains that dominate the near side.
Chang’e 6 is China’s second mission to bring lunar samples back to Earth and its second landing on the moon’s far side, following Chang’e 4’s touchdown in 2019 and Chang’e 5’s sample retrieval from the near side in 2020. No other nation has accomplished this feat, making the samples highly valuable for scientists worldwide eager to study them.
One of the researchers excited about this opportunity is James Head, a research professor emeritus at Brown University. Head, who has extensive experience with lunar exploration from his involvement in NASA’s Apollo program, now collaborates with China’s planetary science community. He highlights China’s significant investments in planetary science, which have positioned the nation as a major player in space exploration, with successful missions to Mars and plans for an asteroid rendezvous mission.
The SPA Basin, where Chang’e 6 landed, is a geological treasure trove. It contains fragments from different parts of the moon, each offering unique insights into lunar history. The samples from the basin’s Apollo crater, which is about 2.5 billion years old, are expected to provide a broad overview of the moon’s evolution.
The successful sample return mission is not just a scientific triumph but also a stepping stone for China’s future space ambitions. China aims to leverage the experience gained from these missions to pursue more complex projects, such as a Mars sample-return mission.
China has also announced plans to land humans on the moon by 2030, a timeline that rivals NASA’s goal of sending astronauts to the lunar surface by 2026 through its Artemis program. Both nations are focusing on the moon’s south pole, which is believed to be rich in resources like water ice. This resource could be crucial for sustaining lunar bases and providing rocket fuel for further space exploration.
To bolster their lunar programs, both the U.S. and China are establishing international partnerships. NASA’s Artemis Accords have garnered support from 43 nations, promoting principles for sustainable space exploration. Meanwhile, China and Russia are working on an International Lunar Research Station, inviting other countries to participate.
Despite the competitive nature of this new space race, there are signs of potential collaboration. For instance, NASA and U.S. researchers are exploring ways to study the lunar samples brought back by Chang’e 6. This cooperation, facilitated through multilateral agreements, could pave the way for “science diplomacy” and mutual benefits from shared research.
The race to the moon is not merely about landing astronauts but securing strategic advantages and resources for future space missions. The moon’s south pole, with its water ice reserves, is particularly attractive as it could serve as a fueling station for missions to Mars and beyond. This new era of lunar exploration is set to shape the future of space exploration, with the moon serving as a critical gateway to the universe.
