Fig. 2 Analysis of physical and mechanical properties of lunar soil based on “Yutu” 2 wheel-earth interaction
The team estimated the mechanical properties of the lunar soil based on the information on the interaction between the lunar rover wheel and the lunar surface and the ground mechanical model. The results show that the pressure-bearing properties of the lunar soil regolith are similar to the dry sand and sandy loam on the earth, and are similar to those in the American Apollo program. Compared with typical lunar soil, it has stronger pressure bearing characteristics. Large lumps of soil were observed adhering to the wheels of “Yutu 2” in images from different locations, while the wheels of “Yutu 2” basically had no clay phenomenon, indicating that the lunar soil cohesion near the landing area of Chang’e 4 is relatively large , the reason may be that it contains a higher proportion of aggregates, which makes soil particles more likely to agglomerate after being rolled by wheels.

On the week of 13th March 2022 in CNSA _China National Space Administration -China – People’s Republic of China……..During the Two Sessions of which was held during in the People’s Hall during the week of 13th March 2022 China – People’s Republic of China CNSA China National Space Administration and its Partners plans to realize the Mars sampling return mission by 2030] China Daily reported on March 6 that Wu Weiren, member of the Standing Committee of the National Committee of the Chinese People’s Political Consultative Conference and chief designer of China’s lunar exploration project, said recently that my country plans to realize the Mars sampling return mission by 2030. The difficulty of the project is much greater than that of lunar sampling and return. The first problem to be solved is to develop a launch vehicle with greater thrust. In the follow-up, China is also preparing to conduct marginal exploration of the solar system. “The sun is about 150 million kilometers from the earth, which is an astronomical unit. We plan to achieve the ‘double hundred’ goal in 2049, that is, on the 100th anniversary of the founding of New China, to complete 100 astronomical units, which is 15 billion kilometers away “Deep space exploration” China plans to realize the Mars sampling return mission by 2030
China will carry on its moon research in the future with Chang’e-6, Chang’e-7 and Chang’e-8 missions by 2030. After 2030, a new set of missions will be carried out to complete the construction of an international lunar research station by 2030….he Chang’e-6 is scheduled to bring back to Earth lunar samples with a mass of up to 2 kilograms; the Chang’e-7 will be tasked with landing on the lunar south pole and detecting local natural resources; and the Chang’e-8, working in collaboration with Chang’e-7, is going to scout how to exploit lunar resources.
According to Wu, the Chang’e-6 and Chang’e-7 are expected to be launched around 2025.
Future missions also include the development of a special craft, which can fly from the landing site to lunar craters to help scientists look for traces of water. If water is present, it could provide resources for future crewed missions on the moon, Wu noted.
After 2030, a new set of missions will be carried out to complete the construction of an international lunar research station by 2035….
“There will be multiple rovers and landers working in the future moon station and a lunar-based communication network to support these spacecraft,” Wu said. “The lunar research station can also function as a transfer outpost for the solar system and even deeper space explorations.”

On the 19th February 2022 week Hong Kong SAR – Beijing Time CNSA CLEP – China National Space Administration –China Lunar Space Program has released the 23rd batch of scientific data released by Chang’e-4 this month’s data came relatively late, but the content is very rich. More than 240 photos include more than 30 color photos. The data collection time announced this time is during the day of the 27th month (2021.02.04~2021.02.19).
is in the last month day In , experts analysed a “milestone” shaped stone, which, in fact, wasn’t the only similarly shaped stone nearby. Just south of the “milestone”, there is another similar stone, which the driving team calls a “stalagmite”, the relationship between the two is marked in Figure 1 (map from Chapter 27 of the Driving Diary). The focus of this moon and day detection is on this “stalagmite”, and the specific process is full of twists and turns. It is recommended that you read the original text of “Driving Diary”. Data source: Lunar and Planetary Data Release System
At 4:32 on February 6 2022 Hong Kong SAR- Beijing Time, Yutu-2 successfully woke up and entered the 27th lunar day, during which it spent its third Spring Festival on the moon.
Last month, we detected the “milestone” rock. Once the news came out, it attracted the attention of scientists all over the world. Dan Moriarty, a researcher at NASA, said: “This rock sample has Similar to the shape of a shark fin, it’s definitely unusual. ” He said that both the shape of the shark fin, and the apparent bulge near the edge of the rock, indicate a very young geological age and a relatively short existence at the site where it was found. Clive Neal, a famous lunar expert at the University of Notre Dame in the United States, also expressed his views on the rocks. While the “milestone” has attracted the attention of the international aerospace science community, Chinese scientists are gradually unravelling the mystery of its identity.
Strange discoveries always come in pairs. Last month, the pilots found a “stalagmite” shaped stone standing in the south direction, similar to the “milestone” shape. The two echoed each other. Everyone decided to act immediately and explore again. “Stalagmite”.
The rhythm of the whole moon, day and morning was tight and orderly. After three moves, Yutu No. 2 arrived near the “stalagmite” before noon on the moon. At this time, the shadow of the car body blocked the target, and it seemed to persuade Yutu to take a nap and explore the “stalagmite” again. , we had to wait for the Yutu to wake up from the lunch break to continue the probe.
Under the scorching sun, Jade Rabbit spent its Spring Festival, and before the fifth day of the first lunar month, it started work early in the day and afternoon. The pilots controlled Yutu-2 to turn to the intended detection heading. According to the previous ground planning path deduction, the road detected at this time is flat, and the bright surface of the “stalagmite” should be able to enter the infrared field of view. However, the obstacle-avoidance images downloaded to the ground are full of artistic “alternation of light and dark”, which is different from the “simple and straightforward” that scientists hoped to be completely illuminated by sunlight.
There are so many exciting moments in lunar exploration. It is within reach, but it seems to be so far away. However, the pilots have been very patient in the long-term detection, and proposed three detection plans for the current situation: go straight ahead, detour to the southwest side of the “stalagmite”, and detour to the southeast to wait for next month’s detection.
Here are a few photos synthesized from the original images: Figure 2: Color photos of the “Milestone” taken from a distance Figures 3 and 4: The lunar image taken by Yutu-2 to the “Stalagmite” (you find the Chang’e-4’s photo) Is the lander yet?) Figure 5: A close-up photo of the “stalagmite”
After repeated deductions and demonstrations, the last plan was not very feasible and was first excluded, and the remaining two plans entered the final PK. Drivers detour from the west side and the southeast side to verify the feasibility of the second option. Detouring from the southeast, there are many potholes along the way. After starting, Yutu No. 2 will step into the pit, which is more dangerous; while the west side seems to be flat along the way, but there is a large impact crater near the end position. Yutu No. 2 The No. 1 can only move around in a small area between the impact crater and the “stalagmite”. Not only is its range of activity severely limited, which may cause the solar wings to be blocked, but it must also return to the original path after detection, which is laborious and dangerous. After several rounds of calculation and demonstration, direct detection wins.
The pilots controlled the Yutu for the first attempt. The preliminary results show that the actual infrared field of view is about 4 cm away from the ideal field of view. The second time, everyone adjusted according to the suggestions of the scientists and tried again, but the results were still biased. The two failed attempts, and the time was approaching zero, and the station resources were almost exhausted. Facing the temptation of the mystery behind the moon, the pilots were still reluctant to give up and decided to try again. They urgently extended the measurement and control arc for an hour, adjusted the posture of the jade rabbit and probed again. With all the hard work, the images uploaded this time show that the infrared field of view finally accurately covers the narrow light of the “stalagmite” !
Those who travel a hundred miles are half and ninety. When it is unknown whether success or failure will come next time, persevering may be our only chance. This time Yutu No.2 and the pilots did it! Next time, would you like to challenge and persevere for your dreams?
