China's Chang'e-6 probe lands on the far side of the Moon for the first time in history, collecting samples from the South Pole-Aitken Basin. Learn more about this historic mission
China's recent Chang'e-6 probe mission marks a historic milestone in space exploration. For the first time in human history, a probe landed on the far side of the Moon with the aim of collecting soil samples monthly.
This article details the main aspects of this revolutionary mission, its objectives and the impact on space science.
The Arrival of Chang'e-6 on the Far Side of the Moon
At dawn on a historic Sunday, the Chang'e-6 probe successfully landed on the far side of the Moon. This event was announced by the China National Space Administration (CNSA), marking an unprecedented feat in lunar exploration. The probe landed in the South Pole-Aitken Basin (SPA), a region that until then remained virtually unexplored. This landing was possible thanks to the support of the Queqiao-2 relay satellite, which ensured communication between Earth and the probe during its journey.

Chang'e-6 consists of a combination of modules: an orbiter, a return module, a lander and an ascender. Since its launch on May 3, 2024, the probe has gone through several crucial phases, including Earth-Moon transfer, braking near the Moon, lunar orbit and descent to landing. On May 30, the combination lander and ascender separated from the orbiter and return modules in preparation for landing on the Moon.
The Importance of the South Pole-Aitken Basin
The choice of the South Pole-Aitken Basin as a landing site was not by chance. This region, also known as SPA, is one of the largest impact craters in the solar system, with a diameter of approximately 2.500 km and a depth of 13 km. The Apollo Basin, located within SPA, was the specific location chosen for the landing. Huang Hao, an expert from the China Aerospace Science and Technology Corporation (CASC), highlighted that this choice was motivated by the enormous potential for scientific exploration in this region, in addition to the favorable conditions for communication and telemetry, and the relative flatness of the terrain.
Samples collected from this region can provide valuable information about lunar geology and the history of the solar system. The South Pole-Aitken Basin is rich in minerals that can reveal details about the geological processes that shaped the Moon and, by extension, Earth. Furthermore, studying these samples can offer insights into the presence of water and other vital resources that could be used in future space missions and even possible lunar bases.
The Chang'e-6 Mission: Stages and Technologies
The Chang'e-6 mission is one of the most complex and technically advanced ever carried out by China. The probe was launched on May 3, 2024, and after a period of travel and orbital maneuvers, the lander and ascender finally landed on the Moon on June 2. This process involved several crucial steps:
- Earth-Moon Transfer: After launch, the probe entered a transfer trajectory that took it from Earth orbit to lunar orbit.
- Braking Near the Moon: Upon approaching the Moon, the probe performed braking to reduce its speed and enter a stable lunar orbit.
- Lunar Orbitation: In lunar orbit, the probe underwent several maneuvers to adjust its trajectory and prepare for descent.
- Descent and Landing: Finally, the lander and ascender separated from the orbiter and return modules and descended to the lunar surface, landing in the South Pole-Aitken Basin.
The Queqiao-2 relay satellite played a crucial role in this mission, ensuring continuous communication between Earth and the probe during all phases of the mission. This satellite is essential as the far side of the Moon is not visible from Earth, making direct communication impossible without the aid of a relay satellite.
Future Implications and China’s Role in Space Exploration
The Chang'e-6 mission represents a major breakthrough in space exploration and puts China at the forefront of lunar missions. Collecting samples from the far side of the Moon opens up new possibilities for science and space exploration. These samples could help unravel mysteries about the formation and evolution of the Moon and provide crucial data for future manned missions.
China has ambitious plans for the future of space exploration. With the Chang'e-6 mission, the country demonstrates its technical capacity and its commitment to scientific exploration. Future lunar missions, including the construction of a lunar base, are in the CNSA's plans, reflecting China's growing importance on the global space stage.
In addition to the scientific implications, this mission strengthens China's position as a leader in space technology. Chang'e-6's success could pave the way for international collaborations and inspire other nations to step up their own space exploration missions.
Chang'e-6 is a milestone in lunar exploration
The Chang'e-6 mission is a milestone in lunar exploration and a testament to China's technological and scientific advancement. The successful landing on the far side of the Moon and the collection of samples from the South Pole-Aitken Basin are remarkable achievements that will provide new insights into lunar geology and the future of space exploration. As we continue to explore the universe, missions like Chang'e-6 bring us ever closer to unlocking the secrets of the cosmos and expanding the limits of human knowledge.
With careful planning, advanced technology and an ambitious vision, China is positioned to continue leading space exploration for decades to come, inspiring a new era of discovery and innovation.
