CTOnews.com, October 30, it is expected that at 15:37:26 (±96s) on October 31, the third and final segment of the Chinese space station, the Mengtian Experimental Module, will be launched on a long March 5B remote four rocket at the Wenchang Space launch site in Hainan.

The mission is the final battle for the assembly of the basic structure of the "T" character of the Chinese space station. I wish the Heavenly Palace to add another "one hall" and "space home" three modules in one, together to cheer for China's space!

Yesterday, the staff organized the last inter-system joint exercise before the launch of the Mengtian experimental module. The relevant functions of each system have been checked.

At present, the long March 5B remote four rocket carrying out the launch mission has begun to implement the filling of propellant, and each system has also completed the relevant functional inspection and is ready.

On October 30, 2022, at the Wenchang Space launch site in Hainan, the Mission Medal hung under the tree beside the road, recording every mission carried out here. It is understood that the Mengtian experimental module mission is the sixth battle of the Wenchang launch site to undertake the task of building the space station, and it is also the 20th launch mission since the completion of the launch site.

According to Huang Bing, deputy chief designer of the long March V carrier rocket of the China Aerospace Science and Technology Corporation, in the future, the long March 5 series carrier rockets will gradually enter a high-density launch state, and it is estimated that by 2024, the launch demand will reach four to five a year.

As a new type of carrier rocket specially developed for the construction of China's space station, the long March 5B carrier rocket is currently the new generation of carrier rocket with the largest carrying capacity in low-Earth orbit in China. The launch tasks of the Tianhe core module and the sky-asking experimental module have been successfully completed.

Li Pingqi, deputy director of the General Office of the overall Design Department of the first Institute of Aerospace Science and Technology Group, said that long March 5B fully inherited the development basis of long March 5, and at the same time realized a new development on the basis of long March 5 in order to adapt to the launch of the module segment of the space station. it breaks through four key technologies, such as "zero window" launch of cryogenic rocket, direct entry into orbit with high thrust, separation of large diameter cabin and arrow, and 20.5 meter long fairing. China's low-orbit carrying capacity has been increased from 8.6 tons to 25 tons, laying the foundation for the construction of China's space station.

Liu Bing, deputy director of the long March 5B carrier rocket, said that in the future, long March 5B will also carry out the launch mission of China's first large-scale space survey space telescope, and will also form a combined rocket with the upper stage of the expedition series, which has the ability to launch multi-satellite networks. to meet the needs of different launch missions.

According to reports, in recent years, the long March V series of carrier rockets have successfully completed a series of major national engineering tasks represented by the construction of the space station, fire detection, and lunar exploration. But in the follow-up, the long March V series carrier rockets will undertake more missions.

According to the new demand, the development team of Aerospace Science and Technology Group has carried out relevant research to improve the adaptability of the mission, including the design of a larger fairing to meet the launch needs of high rail large volume load and heavy load; for the constellation launch mission, a multi-satellite launch adapter is developed.

Li Pingqi, deputy director of the General Office of the General Design Department of the first Institute of Aerospace Science and Technology Group, said: "after a series of studies and improvements, the long March 5 series carrier rockets have stronger launch adaptability and adaptability. It can meet the launch needs of more high-value and high-mass loads."

In addition, the Shenzhou 14 astronaut crew is currently in good condition in orbit, and has carried out in-orbit rendezvous and docking operation training and materials and equipment arrangement in cooperation with ground scientists and technicians. In addition, the space station assembly is in good condition, the functional performance is stable, and it has the conditions for rendezvous and docking with the Mengtian experimental module.

The combination of Mengtian experimental module and long March 5 b remote four carrier rocket was transferred to the launch area on October 25. The follow-up work will be carried out according to the plan, such as pre-launch functional inspection and joint testing, and it is planned to choose an opportunity to carry out the launch in the near future.

The Mengtian experimental module is about 17.9 meters long, the maximum outer diameter of the structure is more than 4 meters, and the launch mass is about 23 tons. It has the ability to release micro aircraft in orbit. After launch, the Mengtian experimental module will eventually form a T configuration with the sky and core module and the third module of the experimental module, which also marks the completion of the National Space Laboratory.

CTOnews.com learned that the Mengtian experimental module is mainly for microgravity scientific research, equipped with experimental cabinets with multi-disciplinary directions such as fluid physics and material science, and supports the study of the essential laws of materials such as the solidification mechanism of materials under the cover of gravity, as well as cutting-edge experimental research such as ultra-cold atomic physics.

Long March 5B is the most powerful rocket with low orbit carrying capacity in China. In order to meet the launch needs of large low orbit payloads such as the construction of space stations in China, it took more than 10 years to tackle key problems, overcome four key technologies, and flew for the first time in May 2020. A new generation of manned spacecraft test ship and flexible inflatable cargo return module experimental module were launched.
