Anhui plays an increasingly important role in the field of deep space exploration

What is deep space exploration? It refers to the activity of launching spacecraft to explore the moon and its distant celestial bodies and space. It is an important way for scientific research, technological innovation, and the development and utilization of space resources. In the past 20 years, China has achieved a series of significant achievements in deep space exploration.

Wu Weiren introduced that China has fully mastered technologies such as lunar and Mars probe system design, autonomous navigation and control, high-precision landing and inspection of extraterrestrial celestial bodies, etc; We have developed and constructed an extraterrestrial celestial body remote operation center and a series of large-scale special testing facilities for the coordination of heaven and earth, and have independently developed a space isotope nuclear power supply for the first time.

China has achieved multiple firsts in space science exploration, "said Wu Weiren. For example, he has drawn the world's highest resolution, 7-meter resolution full moon map, and the first international geological profile map of the front and back of the moon, This cross-sectional map is over 300 meters long, obtaining a large amount of original scientific data on the geology, environment, morphology, and other aspects of the moon and Mars, driving the development of basic disciplines such as space physics and space astronomy. Currently, the overall level of research on the moon and planets in China has entered the forefront of the world.

Currently, the Hefei Institute of Materials is undertaking the development task of the CE-7 lunar soil water molecular analyzer, which will achieve the first detection of water ice and hydrogen and oxygen isotopes in the permanent shadow area of the South Pole of the Moon. Water ice detection is also the most important scientific goal of Chang'e-7. The Mozi Telescope, jointly developed by China University of Science and Technology and the Deep Space Exploration Laboratory, is the strongest telescope in the northern hemisphere for optical sky surveys. It has been built and used in Cold Lake, Qinghai, and will conduct research on the search and monitoring of near-Earth objects in the solar system to meet the strategic needs of deep space exploration.

Implementing the Fourth Phase of the Lunar Exploration Project to Build an International Lunar Research Station

Wu Weiren introduced that in the next 15 years, China's deep space exploration will demonstrate and implement ten major engineering tasks in three fields: lunar exploration, planetary exploration, and carrier technology.

Firstly, in the field of lunar exploration, the fourth phase of the lunar exploration project, including the Chang'e 6, 7, and 8 missions, will be implemented, and a basic lunar research station will be built at the south pole of the moon. Next year, Chang'e-6 will be launched to achieve the first international automatic sampling and return of the lunar backside. Around 2026, Chang'e-7 will also be launched and landed at the south pole of the moon. Through orbit, inspection, and leap exploration, detailed resource and environmental surveys will be conducted. In addition, the Chang'e-8 mission will be implemented and new technology experiments such as in-situ utilization of lunar resources will be carried out.

Secondly, build an international lunar research station. It is a comprehensive scientific experimental facility proposed by China and jointly constructed by multiple countries. It operates independently on the lunar surface and orbit for a long time, with short-term participation, and is scalable and maintainable. Capable of energy supply, central control, round-trip between heaven and earth, lunar scientific research, and other capabilities, sustainable development of multi-disciplinary, multi-objective, and large-scale scientific research activities. At present, the Deep Space Exploration Laboratory is cooperating with the National Space Administration to organize domestic academicians and experts to conduct engineering scheme argumentation. In addition, manned lunar landing will also be implemented, and key technology research and implementation plan deepening demonstration are currently underway. It is planned to achieve manned lunar landing around 2030.

We will develop and construct a Queqiao Navigation and Telemetry Integrated Constellation System. Establish an integrated constellation system consisting of a lunar orbiter, a Earth Moon translational point spacecraft, an interplanetary transit station, a planetary orbiter, etc., with functions such as communication, navigation, positioning, and timing. It can provide services for Earth Moon space and deep space spacecraft beyond Mars, and expand support for interplanetary space scientific experiments. As its leading verification satellites, Tiandu 1 and Tiandu 2 satellites will leave the factory from the headquarters of Hefei Deep Space Exploration Laboratory in early January next year, and will then be launched with the Queqiao 2 relay satellite. It will carry out a series of new technology tests and verifications.

Plan to launch the first near-Earth asteroid defense mission

Wu Weiren stated that in the field of planetary exploration in the future, China will not only implement the Tianwen 2 asteroid sampling and exploration mission, which aims to achieve the sampling and return of specific target asteroids, but also carry out near-Earth asteroid defense missions for the first time. In response to the extremely unlikely and highly hazardous event of a near Earth asteroid hitting Earth, we will implement a kinetic energy impact on an asteroid tens of millions of kilometers long, causing it to change its orbit. We will also conduct an impact effect assessment in orbit to achieve 'accurate collision, push, measure, and explain'

Launch the Tianwen III Mars sampling probe. Chinese scientists will achieve Mars sampling and return, making China the first country to obtain Mars samples. "Wu Weiren said, and will also carry out exploration of the Jupiter system and interplanetary space, achieving the orbit of the Jupiter system and the arrival of Uranus, deepening human scientific understanding of the Jupiter system and interplanetary space. In addition, solar system edge exploration will be carried out. The plan is to launch a new type of spacecraft that will reach the solar system edge of 100 astronomical units by the middle of this century, making China's contribution to deepening human understanding of the scientific characteristics of the solar system edge and inner planets, and exploring extraterrestrial life.

In addition, in the field of transportation, the implementation of heavy carrier rocket engineering will be demonstrated, breaking through key technologies such as a 10 meter diameter rocket body and a high thrust liquid oxygen methane engine, to enhance China's low Earth orbit transportation capacity from 25 tons to 150 tons, laying a solid foundation for future deep space exploration.

Wu Weiren stated that in the future, deep space exploration will focus on four major areas: deep space technology, deep space science, deep space resource utilization, and deep space safety. Scientific and technological research will be focused on key directions such as overall deep space exploration technology, deep space energy power, lunar and planetary science, and deep space situational awareness, fully reflecting the country's efforts to achieve significant original scientific research results.
