good news! China Space Station has ushered in the next step, that is, to welcome Mengtian Experimental Cabin , the Wentian Experimental Cabin has implemented in orbital transposition.

I have to say that the progress of China's space station has improved again.

Of course, many people may say, why do you need to exchange interfaces every time you conduct a new round of planning? Do you have to use this one for so many interfaces? What is the reason? Let’s explain it step by step.

Mengtian Experimental Cabin

Mengtian Experimental Cabin is another new experimental cabin after my country's Wentian Experimental Cabin. Of course, the functions of the two experimental cabins are completely different. This experimental cabin is also the second experimental cabin of in my country's space station. The function of the

The main function of the essay experimental cabin is to be researched in space life sciences, and supports the research on the response mechanisms of various types of plants, animals, microorganisms, etc. under spatial conditions, which is equivalent to an experimental cabin in terms of biological properties.

Of course, this study plays an important role in microgravity or gravity-free state and the impact of gravity state on the life mechanism. Therefore, under the construction of space stations in my country, it will be conducive to breakthroughs in the future.

The Mengtian Experimental Cabin is mainly aimed at microgravity scientific research, which focuses on materials research.

This experimental chamber is equipped with experimental cabinets in multiple disciplines such as fluid physics, materials science, combustion science, basic physics and aerospace technology experiments, supporting the research on the essential laws of matter such as multi-phase flow and phase change heat transfer under gravity masking, basic combustion process, material solidification mechanism, and cutting-edge experimental research such as ultra-cold atomic physics.

So, the functions of these two experimental chambers are completely different. Of course, this also shows that China's space station is a multifunctional model and is not a single research experiment.

So, we are better than other launches earlier. After connecting to the space station, we can implement correlation research and obtain correlation results early. After the launch of the Mengtian Experimental Cabin, the basic configuration of the entire space station included Tianhe Core Cabin, Wentian Experimental Cabin I and Mengtian Experimental Cabin II, each cabin has a scale of 20 tons.

. During its operation, my country will also implement manned spacecraft missions many times to provide passenger transport. The supply support is provided by Tianzhou cargo spacecraft . This is the general situation. Why does

launch the Mengtian Experimental Cabin and still need to be transferred?

We also said above that whether it is performing correlation tasks such as Wentian Experimental Cabin Launch or Shenzhou series, my country must conduct correlation translocation, and Mengtian Experimental Cabin has been launched, so Wentian Experimental Cabin needs to be translocated and waited.

This time, the Wentian Experimental Cabin first completed the relevant status settings, and then separated from the Tianhe core Cabin. Then, the index was completed by plane indexing, and the node cabin lateral port was docked again.

This is also the first time in my country that the indexing mechanism is used to implement large-scale cabin indexing operations in orbit. After the transfer of the Wentian experimental cabin was completed, the space station assembly changed from the two-cabin "One" configuration to the two-cabin "L" configuration.

Then why do you do this? Indeed, doing this makes many people feel that it is like a waste of time and also requires testing various technologies. Is this entirely "causing trouble" for themselves? Actually, this is not.

First of all, we must know that in the transition stage, it is itself a stage for my country to conduct correlation technology verification.

For example: In this process, my country adopted the "combination punch" model to convert, and used an index mechanism of more than 100 kilograms to drive more than 20 tons of experimental cabin for large-scale transfer. In this process, we must ensure that the combination posture is closed and the space station can be actively controlled to change in the suspended state. If the control is slightly poor, there will be "imbalance" at both ends, which may bring serious consequences.

This is just one of them, but to be precise, it is necessary to integrate difficult actions such as forward evacuation, cabin section indexing, and lateral docking. The purpose of this transformation is also very simple, which is to be more conducive to operationality.

Although China's space station has many interfaces, every time we carry out a task, we need to find a port that is most conducive to docking and achieve perfect cooperation with docking, which is what we want most. Therefore, every time you perform a task, you must perform correlation interface adjustment, which is the reason.

With the countdown to the launch of the Mengtian Experimental Cabin, the completion of the construction of the China Space Station has entered the final "sprint stage". At this time, many people may have thought about the development of China's space stations opening up to foreign countries. Indeed, the construction of China's space stations is indeed open to foreign countries.

India, Japan and 17 other countries joined the Chinese space station

Although, the Chinese space station is still in the "sprint" stage. However, the development goals of China's space station are very clear, that is, to share globally and create value together.

So, many countries in the world have also applied to join the China Space Station. Among the first batch of scientific experimental projects, 17 countries joined the China Space Station, including Switzerland , Poland , Germany, Italy, Norway , France, Spain, Netherlands , India, Russia, Belgium , Kenya , Japan, Saudi Arabia , Mexico and other 17 countries.

Therefore, the development trend of China's space station project is very obvious and is also allowed to enter other countries. Many people may be worried about other countries' destruction. In fact, this is not necessary. That is, China's space station also has its own rules, and those that do not meet the requirements are prohibited.

Among the first batch of scientific experimental projects, my country rejected the United States because the United States' projects do not meet China's requirements. Therefore, although China's space station is open, we are not allowed to join as long as it does not meet the requirements. This is China's "principle" and China's "requirement".
