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…..

According to the National Space Administration, at 7:38 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.
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.
At 17:27 on May 3rd Friday 2024 Beijing time CNSA –China National Space Administration, the Chang’e-6 probe was successfully launched by the Long March 5 Yao-8 carrier rocket from the Wenchang Space Launch Site in Hainan Province, China, People’s Republic of China., and accurately entered the Earth-moon transfer orbit. The launch mission was a complete success. The Chang’e-6 probe has embarked on the world’s first return journey for sampling from the far side of the moon. The pre-selected landing and sampling area is the South Pole-Aitken Basin on the far side of the moon.
[Chang’e-6 successfully landed in the South Pole-Aitken Basin on the far side of the moon] According to the National Space Administration, at 06:23:15:861
Beijing time today, the Chang’e-6 lander and ascender combination, supported by the Queqiao-2 relay satellite, successfully landed in the pre-selected landing area of the South Pole-Aitken Basin on the far side of the moon. At 6:09 on June 2, the Chang’e-6 lander and ascender combination began to implement power descent, and the 7500 Newton variable thrust main engine was turned on. During this period, the combination made rapid attitude adjustments and gradually approached the lunar surface. After that, obstacles were automatically detected through the visual autonomous obstacle avoidance system, and a visible light camera was used to select a rough safe point based on the brightness of the lunar surface. It hovered 100 meters above the safe point, and laser three-dimensional scanning was used to take precise photos to detect obstacles on the lunar surface. Finally, the landing point was selected and a slow vertical descent began. When it was about to reach the lunar surface, the engine was shut down, and the buffer system was used to ensure that the combination reached the lunar surface in a free fall manner, and finally landed smoothly in the South Pole-Aitken Basin on the far side of the moon.
According to the China Academy of Space Technology, Chang’e-6 is one of the most complex spacecraft systems developed by China so far. The propulsion subsystem developed by the Sixth Academy provides it with the orbiter propulsion subsystem, lander propulsion subsystem and ascender propulsion subsystem. They are composed of 3 orbit control engines, 74 attitude control engines and more than 200 supporting single units such as tanks, gas cylinders, valves, circuit boxes, pressure sensors, etc. Among them, 1 7500N variable thrust engine is used for a smooth soft landing on the moon, and 2 3000N engines are used for the probe’s near-moon braking “in-orbit braking” and lunar takeoff. With their help, the Chang’e-6 probe can complete a series of “difficult actions” in space on its own .
The payload carried by the Chang’e-6 lander will work as planned and carry out scientific exploration missions. The international payloads of the Chang’e-6 mission, the European Space Agency’s lunar surface negative ion analyzer and the French lunar radon detector, are about to start working, and the Italian laser corner reflector has been deployed.
Since the Chang’e-6 probe was launched into orbit on May 3, 2024, it has successively experienced the processes of earth-moon transfer, near-moon braking, circumlunar flight, landing and descent. The Chang’e-6 probe consists of an orbiter, a returner, a lander and an ascender. On May 30, the lander and ascender combination and the orbiter and returner combination were separated in orbit. After the lander and ascender combination lands successfully, the lander will conduct status checks and settings such as the deployment of solar panels and directional antennas under ground control via the Queqiao-2 relay satellite, and then officially begin sampling work on the far side of the moon, which will last about two days. The lunar soil samples and lunar surface rocks will be collected by drilling with a drill and by using a robotic arm to achieve multi-point and diversified automatic sampling. At the same time, scientific explorations such as on-site investigation and analysis of the landing area on the far side of the moon and analysis of the lunar soil structure will be carried out to deepen the research on the origin and evolution history of the moon.
At 17:27 on May 3rd Friday 2024 Beijing time CNSA –China National Space Administration, the Chang’e-6 probe was successfully launched by the Long March 5 Yao-8 carrier rocket from the Wenchang Space Launch Site in Hainan Province, China, People’s Republic of China., and accurately entered the Earth-moon transfer orbit. The launch mission was a complete success. The Chang’e-6 probe has embarked on the world’s first return journey for sampling from the far side of the moon. The pre-selected landing and sampling area is the South Pole-Aitken Basin on the far side of the moon.
About 37 minutes after the Long March 5 Yao-8 carrier rocket flew, the rocket separated, sending the Chang’e-6 probe directly into the predetermined Earth-moon transfer orbit with a perigee altitude of 200 kilometers and an apogee altitude of about 380,000 kilometers. The Chang’e-6 probe consists of an orbiter, returner, lander, and ascender. Subsequently, with the support of ground measurement and control and the Queqiao-2 relay satellite, the Chang’e-6 probe will undergo processes such as earth-moon transfer, near-moon braking, orbiting the moon, landing and descent, and soft landing on the lunar surface, and finally reach a pre-selected area on the far side of the moon. Collect lunar surface rock and soil samples, and conduct scientific exploration at the same time. After completing the sampling and packaging, the ascender will take off from the lunar surface, then carry out lunar orbit rendezvous and docking and transfer the samples to the returner; the returner will undergo processes such as moon-to-earth transfer, approaching the second cosmic speed and re-entering the earth, and finally carry precious Lunar samples returned to Earth.
During the filming break, an aerospace worker told me that once she went to the Xichang launch base to visit an old leader. When the satellite was being transferred from the factory to the rocket assembly, she saw the chief engineer of the satellite kissing the satellite deeply and running after him. Follow the satellite and take pictures all the way. I burst into tears at that time… The launch of each satellite is like a child bidding farewell to his homeland, embarking on a journey alone with no return, bidding farewell to Mother Earth, and rushing to the unknown and vast universe!
At that moment, I realized how affectionate, tender, sentimental, and heroic this undertaking is, like the sky, like the ocean, like the storm, like the boiling rain of time… Chang’e-6 was successfully launched! Move forward with a heavy load and pay tribute to China Aerospace!
