According to the National Space Administration, at 4th June 2024 7:38 Beijing time today, the Chang’e 6 ascender carrying lunar samples took off from the far side of the moon. After the 3000N engine worked for about 6 minutes, it successfully sent the ascender into the scheduled lunar orbit. From
June 2 to 3, Chang’e 6 successfully completed intelligent and rapid sampling in the South Pole-Aitken Basin on the far side of the moon, and packaged the precious lunar far side samples in the storage device carried by the ascender in a predetermined form. During the sampling and packaging process, researchers simulated the geographical model of the sampling area and simulated sampling in the ground laboratory based on the probe data transmitted back by the Queqiao-2 relay satellite, providing important support for sampling decisions and operations in various links.
The Chang’e-6 lunar flag display system was jointly developed by China Aerospace Sanjiang Group and Wuhan Textile University and other units. In response to the extreme environmental requirements of high and low temperature alternation, high vacuum and strong ultraviolet radiation in this mission, the lunar flag team of Academician Xu Weilin of the State Key Laboratory of New Textile Materials and Advanced Processing Technology of Wuhan Textile University..
selected basalt materials. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. China has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, basalt fiber) for key development, and has achieved industrial production. Using natural basalt formed by volcanic eruptions as raw materials, it is crushed and put into a melting furnace, heated to a molten state of 1450~1500℃, and quickly drawn through a platinum-rhodium alloy drawing plate. This is how basalt fiber is made. When basalt fiber is manufactured, it has excellent high temperature resistance and thermal shock stability, and can remain unchanged at a temperature of 650°C. It also has durability, weather resistance, UV resistance, water resistance, and oxidation resistance comparable to natural basalt stone. 嫦娥六号…..

Intelligent sampling is one of the core key links of the Chang’e 6 mission. The probe withstood the high temperature test on the far side of the moon, and collected lunar samples by drilling with a drill and taking samples from the surface with a robotic arm, realizing multi-point and diversified automatic sampling.
嫦娥六号 The lander and ascender took a group photo] On June 3, 2024, the “mobile camera” carried by Chang’e 6 moved autonomously and successfully took and sent back a group photo of the lander and ascender
The Chang’e-6 lander was equipped with a landing camera, panoramic camera, lunar soil structure detector, lunar mineral spectrometer and other payloads that were powered on normally and carried out scientific exploration as planned, playing an important role in scientific exploration tasks such as lunar surface morphology and mineral composition detection and research, lunar shallow structure detection, etc. Before the probe drilled and sampled, the lunar soil structure detector analyzed and judged the underground lunar soil structure in the sampling area, providing data reference for sampling. The international payloads
carried by the Chang’e-6 lander, such as the European Space Agency’s lunar surface negative ion analyzer and the French lunar radon gas detector, worked normally and carried out corresponding scientific exploration tasks. Among them, the French lunar radon gas detector was powered on during the Earth-Moon transfer, lunar orbit phase and lunar surface working phase; the European Space Agency’s lunar surface negative ion analyzer was powered on during the lunar surface working phase. The Italian laser corner reflector installed on the top of the lander became a position control point that can be used for distance measurement on the back side of the moon.
After the surface sampling was completed, the five-star red flag carried by the Chang’e-6 lander was successfully unfolded on the back side of the moon. This is the first time that China has independently and dynamically displayed its national flag on the back side of the moon. The national flag is made of new composite materials and special technology. Due to the different landing position on the moon, the Chang’e 6 national flag display system has been adaptively improved on the basis of the Chang’e 5 mission.
