China News Agency, Beijing, December 17 (Guo Chaokai) In the early morning of December 17, the Chang'e-5 returner successfully landed in the planned area of Siziwang Banner in Inner Mongolia.
The Chang'e-5 mission is one of the most complex and difficult missions in China's aerospace industry to date.
With such difficulty, why does China go to the moon to "dig earth"?
In an exclusive interview with China News Agency "China Focus Face-to-face", Pei Zhaoyu, deputy director of the China National Space Administration's Lunar Exploration and Space Engineering Center and spokesperson for the Chang'e 5 mission, responded to this.

Pei Zhaoyu said that from the engineering perspective, China's lunar exploration project has planned a three-step "around and down" process. Through around and down, China has mastered some technologies and has the ability to go back and forth between the earth and the moon by returning.
In terms of science, China conducts a comprehensive census through "circumnavigation" and a detailed regional survey through "drop". However, due to weight restrictions, the weight of scientific instruments carried is limited and the accuracy is limited, which cannot be compared with ground-based instruments and equipment.
After obtaining the samples, through fine research on the ground, combined with the scientific data of "rounding" and "falling", the understanding of the moon may be more comprehensive and more refined.
He emphasized that China has been conducting space activities in earth orbit for many years and is relatively mature; while the moon and deep space have rarely been involved.
The moon and deep space exploration are good carriers for driving the development of space technology. The development of the moon and deep space exploration is not only a long-term strategic need, but also a need for the development of space technology.

Pei Zhaoyu revealed that China regards the lunar scientific research station as the main goal of the future development of lunar exploration and develops the construction of the lunar scientific research station in an open and cooperative manner.
"We have put forward an initiative to jointly build an international lunar research station internationally, and we have also received responses from some countries and international organizations." Pei Zhaoyu said.
In terms of planetary exploration, China successfully launched the Tianwen-1 Mars probe on July 23 this year, taking the first step in planetary exploration.
According to Pei Zhaoyu, according to the plan, China will also implement an asteroid exploration mission, a Mars sampling return mission, and a deep space exploration mission for Jupiter system exploration and interplanetary crossing in the next ten years.
"For interplanetary exploration, Chinese experts have conducted long-term demonstrations, thinking about how to achieve more detection targets with the least cost and the least number of missions. From this perspective, temporarily put Venus aside. But it is temporary. We May cooperate with other countries to carry out exploration activities of Venus or other planets." Pei Zhaoyu said.
He pointed out that, on the whole, China's exploration targets have entered the interplanetary space from the moon, and the exploration targets have moved from mastering space technology to the comprehensive development of space technology, space science and space applications, and the development mode has shifted from being independent and independent to fully open and cooperative. The stage.
