At about 13:20, the Beijing Aerospace Flight Control Center injected high-precision navigation parameters into the Chang’e-6 orbiter and returner combination through the ground measurement and control station. After that, the orbiter and returner unlocked and separated normally at about 5,000 kilometers above sea level in the South Atlantic Ocean, and the orbiter completed the orbit avoidance manoeuvre as planned. At about 13:41, the Chang’e-6 returner entered the Earth’s atmosphere for the first time over the Atlantic Ocean at a height of about 120 kilometers above the ground at a high speed close to the second cosmic speed (about 11.2 kilometers/second), and implemented its first aerodynamic deceleration. .
After descending to a predetermined altitude, the returner jumped upwards out of the atmosphere over the Indian Ocean, and began to glide down after reaching the highest point. After that, the returner re-enters the atmosphere and implements secondary aerodynamic deceleration. When it drops to an altitude of about 20 kilometers above the ground, the returner switches to the parachute opening attitude. At an altitude of about 10 kilometers, the return vehicle opened its parachute, completed the final deceleration and maintained a stable attitude, and then landed smoothly in the predetermined area. The launch site and recovery system technicians responsible for the search and recovery mission conduct returner searches based on the location information and action paths reported by the Beijing Center, discover the target in a timely manner, confirm that the returner status is normal, and carry out recovery work in an orderly manner as planned. After the final Chang’e-6 returner completes necessary ground processing, it will be airlifted to Beijing to open the cabin and remove the sample container and cargo. The National Space Administration will choose an opportunity to hold a handover ceremony to formally hand over lunar samples to the ground application system, and will subsequently carry out work related to sample storage, analysis and research. The Chang’e-6 probe was launched from the Wenchang Space Launch Site in China on May 3 and entered the Earth-moon transfer orbit. After orbit correction and near-lunar braking, the probe successfully entered a lunar orbit. After that, the probe experienced the separation of the lander and ascender assembly, and the orbiter and returner assembly. With the support of the Queqiao-2 relay satellite, the lander and ascender assembly carried out orbital descent and powered descent around the moon.
On June 2, it accurately landed in the pre-selected area of the South Pole-Aitken Basin on the far side of the moon and carried out sampling work. On June 4, the ascender was ignited for takeoff and accurately entered orbit. On June 6, it completed the rendezvous and docking with the orbiter and returner assembly and sample transfer. After that, it separated from the orbiter and returner assembly as planned and was controlled. The moon falls. After that, the orbiter and returner combination experienced 13 days of waiting around the moon. After completing two lunar-Earth transfer incidences and one orbit correction, the returner separated from the orbiter on June 25 and carried heavy samples from the back of the moon. Return to Earth.

The engine is the power source of the rocket, and its development process is very complicated. Test run is an important link in the engine development process, and there are dozens of types. In layman’s terms, engine test run is the process of igniting the engine and verifying the rationality of its design scheme and process reliability. This is an indispensable and important part of the development and delivery of a type 1 engine. It will run through all stages before and after engine development. Each stage of test run has different meanings, and the ignition time varies from a few seconds to hundreds of seconds.
It is reported that the engine used in this test run uses advanced liquid oxygen kerosene as fuel, which is improved and iterated from the high-thrust liquid oxygen kerosene engine used by the new generation of launch vehicles such as the Long March 5. The thrust reaches 130 tons. The R&D team of the Sixth Academy of Aerospace Science and Technology Group adheres to the concept of digital design, and has successively overcome key technical problems such as engine start-up and shutdown sequence, engine wide-range continuously variable thrust, and engine long life and high reliability.
In addition, the continuous success of the test run has fully verified the reliability of a number of new carrying process technologies. The engine production of this test run adopts the concept of intelligent manufacturing, and actively applies new materials, new processes, and new technologies. The inner wall of the thrust chamber of the core component adopts a new protective coating, key assemblies adopt automatic welding technology, and a large number of components adopt 3D printing technology.
During the preparation of the engine test run, the participants in the research and test conducted tests and verifications on each subsystem of the test through comprehensive means such as digital modelling, simulation calculation, and system debugging. The successful test run shows that the test area has greatly improved the multi-station parallel test run capability and test efficiency by optimizing the workflow.

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…..
