CCTV.com news: patrol the sky and explore the sky, decrypt the starry sky, today (November 22) "Ask to the end", we will track China's space exploration industry continuously. In the past year, "Zhurong" has explored the fire, "Xihe" has sunrise, and "Tianhe" has traveled across the stars, and the Chinese have their own "space home". From space station to the ground and the farthest distance is 400 million kilometers from space station to the ground fire, the pace of pursuing dreams of stars is more steadily, and China's deep space exploration is getting further and further. Yesterday, the "United Nations/China Space Exploration and Innovation Global Partnership Seminar" co-organized by the National Space Administration, Hainan Provincial People's Government, and the United Nations Foreign Space Department opened in Haikou. A total of representatives from more than 80 countries and regions around the world "discussed space together". Everyone is very concerned about when the footprints of Chinese astronauts can be left on the moon? We already have China Space Station , so when will lunar scientific research station be there? When can ordinary people travel on earth and moon, or even on earth and fire? Where will my country's deep space exploration go in the future? This series of seemingly out of reach now has answers to the nearest answers. Today's "Ask to the end" focus on China's space exploration.
At a seminar held in Haikou, a "deep space exploration timetable" sparked heated discussion. What are the steps taken by my country's deep space exploration? How can we fly far away in the next ten years? Generally speaking, the moon, 380,000 kilometers away from the Earth, and space beyond the space belong to the category of "deep space". The current detection activities are carried out through three ways: observation of deep-space objects with the help of observation equipment on the ground and space orbit , accessing close inspections with unmanned spacecraft, landing machines, etc., and astronauts landing in celestial bodies. So, how is China's "timetable" for deep space exploration arranged? Previously, a reporter from the Central Station exclusively interviewed Academician Wu Weiren, chief designer of China's lunar exploration project, to listen to his interpretation.
How many steps will China's deep space exploration take in the next 10 to 15 years?
Academician Wu Weiren, chief designer of China's lunar exploration project: deep space exploration is lunar exploration, the second is asteroid exploration or impact, the third is planetary exploration, and the fourth is that we want to launch the heavy launch vehicle , which will increase our current rocket thrust by about 4 times, and prepare for manned landing on Mars , landing on the moon, and large-scale transportation in near-Earth space.
Academician Wu Weiren, chief designer of China's lunar exploration project: Our country's lunar exploration project began in 2004. The original plan to circumvent the moon, fall the moon and sample return have basically been completed. Chang'e 6 , we have now included it in the fourth phase. Chang'e 7 , Chang'e 8 , and the construction of scientific research stations are linked together. The first three major steps have been completed, and we will implement the fourth phase below. There may be a fifth phase project and a sixth phase project in the fourth phase project, which is all the next thing... When will the new generation of manned rocket be completed for development?
Whether deep space exploration can go further and further, the power-heavy rocket is the key. The "special car" of the Chinese space station we are familiar with - Long March 5 . Its thrust can meet the carrying capacity of low-Earth orbit, but if you want to complete manned moon landing or even explore further space, you need a heavy launch vehicle with stronger thrust. So, is there a timetable for the development of the new generation of manned rockets?
According to reports, the diameter of the new generation of manned rockets is equivalent to that of the Long March 5 launch vehicle. By comprehensively applying mature rocket technologies, it will meet my country's manned moon landing mission needs.
Academician of the Chinese Academy of Engineering, Aerospace Science and Technology Group Chief Consultant of the Long March Series Launch Vehicle Long Lehao : is equivalent to the first stage of the core of the three Long March 5. Bundle it, each core stage is connected in parallel with three combinations, and each combination has 7 engines, and each engine has a thrust of about 120 tons. It is just such a giant, and of course there are two stages, so the three Chinese are launched in two.The carrying capacity of low-Earth orbit can reach about 70 tons. The capacity of the Earth-Moon transfer orbit is that the carrying capacity of the Earth-Moon transfer orbit is about 27 tons. This may be launched in two times, which will (enable) three Chinese people to the moon before 2030.
At the same time, Academician Long Lehao introduced that my country's heavy launch vehicle is also under development. Its body diameter reaches 10.6 meters and its height is about 110 meters. The carrying capacity of the low orbit can reach more than 150 tons, and the capacity of the earth-moon transfer orbit reaches more than 50 tons. This will be the rocket with the strongest carrying capacity in the future.
Academician of the Chinese Academy of Engineering and Chief Consultant of the Long March Series Launch Vehicle of the First Dean of the Aerospace Science and Technology Corporation Long Lehao: A rocket like exceeds the carrying capacity of all rockets in history. In the future, in addition to realizing our far-reaching capabilities, such as manned Mars exploration, and the establishment of lunar base , and even for direct civil use in the future, it will build a space solar power station for transportation. The progress is pretty good now, and the specific appearance has been made. The first and second stages of engines have been conducted accordingly on the whole system's short-range hot test test assessment, which means that the specific plan has been decided. It is entirely possible that the first flight test should be entered in 8 to 10 years.
When will "Chang'e" return to the moon? When will the Chinese land on the moon?
There are actually many questions about the time point. When will Chang'e 6 be sampled and returned? When will Chinese astronauts land on the moon? When will the moon Internet be built? In response, Academician Wu Weiren, chief designer of China's lunar exploration project, said that in 2024, Chang'e-6 will be sampled and returned as planned; by around 2030, Academician Wu said that Chinese people can put their footprints on the moon; in the future, they can also play mobile phones, videos, and even watch the World Cup on the moon, because Academician Wu said that as long as the moon Internet is built, it can cover the earth-moon space, lunar space and even interstellar space, and everything that lives on the earth can be moved to the moon.
What is the moon scientific research station like? When will it be built?
Now we already have the China Space Station, so how far is the lunar scientific research station from us? Academician Wu said that for the construction of the lunar scientific research station, we must first form a basic type of an international scientific research station, and then expand it into an international lunar scientific research station on this basis. So, how does this happen? When will it be built? Come and listen to his introduction.
Academician Wu Weiren, chief designer of China's lunar exploration project: The fourth phase of lunar exploration projects include Chang'e 7, Chang'e 8, etc. We want to build a basic lunar scientific research station on the moon, covering landers, lunar rover , and leverage. There is also an orbiter in the orbit, and we can observe there at any time. The lever must take off from the moon or take off multiple times.
Academician Wu Weiren, chief designer of China's lunar exploration project: International Lunar Research Station is also based on it. Some spacecraft from other countries are on it, jointly building a scientific research station in the South Pole of the Moon. Because the South Pole of the Moon has an advantage, the back of the Moon cannot be seen and the sun cannot shine? There may be a long period of polar day and polar night phenomena on the back of the moon, so it will at least have a little light. Although the light is insufficient, about minus 80℃ to minus 100℃, then people and machines can still carry it for a long time.
Academician Wu Weiren, chief designer of the lunar exploration project in China: Our country is the first country to propose to set up a scientific research station in the Antarctic of the moon.
Academician Wu Weiren, chief designer of China's lunar exploration project: first landed safely, and there were also walking lunar rovers. Now our Chang'e-3 and Chang'e-4 have both released lunar rovers, but our car is very small, 120 kilograms.In the future, the car will be bigger than now, because our rocket has greater thrust and can also be used to ride people. For example, the Americans have now built a lunar rover, which has two people, one driving, one resting, a bed, and a bathroom... The third part also has energy supply. For example, we are developing a new energy system and using nuclear energy on it, which can solve energy problems with high power for a long time. There are also communication facilities, websites, and base stations to realize communication with the ground, such as communication with Mars or other interstellar communication transit.
Academician Wu Weiren, chief designer of China's lunar exploration project: Some people say that taking off from the moon, flying to Mars, and flying to other planets in the future will save time and effort. If you take off from the moon, it will be much less difficult. We astronauts hope to be able to hit the moon within 10 years, probably at this pace. Around 2028, our basic model was built.

From the Shenzhou flying to Chang'e flying to the moon, to the sky asking about the fire, Xihe chasing the sun, the Chinese people's exploration of the mysteries of the universe has never stopped. What are the "famous scenes" that make you remember? Let’s sort out and take stock together.
For many years, the moon has been facing us with a head-on view, which has led to infinite fantasy about its back. Some people think there is an alien base on the moon back, while others think that moon back has the secret of the ancient solar system. In short, there are many different opinions. It was not until Chang'e-4 successfully landed on the back of the moon that all these puzzles were answered. When Chang'e-4 landed, the "little rabbit" it carried - the Yutu-2 lunar rover, had a mission on its shoulders. Since landing, the Yutu 2 lunar rover has completed its dormant night on the 44th moonlight night, and its cumulative mileage on the back of the moon is 1,239.88 meters. Explore the back of the moon, and win the osmanthus in the toad palace, just to leave a "footprint of China".
May this year marks the first anniversary of the successful "fire" of . On May 15 last year, the Tianwen-1 probe, , landed on the southern part of the Mars Utopian Plain. The successful landing of my country's first Mars exploration mission marks an important step in the interstellar exploration journey, achieving a leap from Earth-moon system to interplanetary, leaving the Chinese imprint on Mars for the first time. Now, far away from Mars hundreds of millions of kilometers, Zhurong Mars rover is dormant. It is expected that around December of the year, the Zhurong Mars rover inspection area will enter early spring. After the environmental conditions improve, it will resume normal work. The sky asks the "fire" to decrypt the starry sky just to find the "Chinese answer" in space.
After the first Mars exploration mission of Tianwen-1 was successfully completed, the next step will be to start the exploration of asteroids. Wu Yanhua, deputy director of the National Space Administration, once said that a detection of asteroids including landing, sampling and return tasks will be carried out next. Immediately afterwards, we will carry out sampling and return of Mars, exploration of Jupiter system, and interplanetary exploration. Wu Yanhua said that the planetary exploration project is planned to be completed within the next 10 to 15 years. At present, my country is still conducting demonstrations on medium- and long-term development strategic planning, such as the detection of the margins of the solar system, the launch of large space solar power plants, the launch of larger detection equipment on Mars, etc. The Chinese will go further and further in exploring the universe.
