[China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success]

On June 23rd 2024, China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success. The rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation.

 At about 1300 hours Beijing Time, at the Jiuquan Satellite Launch Center, Inner Mongolia, China, People’s Republic of China , a 3.8-meter-diameter reusable carrier rocket new technology verification arrow was erected on the launch pad. Three variable thrust liquid oxygen-methane engines were ignited, spewing blue tail flames. The rocket body rose to an altitude of about 12 kilometers. The central engine adjusted the thrust, and the rocket descended in a controlled manner. At 50 meters from the ground, the four landing legs unfolded, and then the rocket slowly descended, approaching zero altitude, and landed steadily on the recovery field, achieving a fixed-point vertical soft landing.


This test is currently the largest-scale vertical take-off and landing flight test of a reusable carrier rocket in China, and it is also the first application of the domestically developed deep variable thrust liquid oxygen-methane engine in a 10-kilometer-class return flight.
The entire test took about 6 minutes. The rocket went through five stages: accelerated ascent, decelerated ascent, accelerated descent, decelerated descent, and slow descent, achieving “take-off, accurate control, unfolding, and stable landing”.

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 completes sampling and ascender takes off from the far side of the moon and enters the scheduled lunar orbit]

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…..

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.
