1 Does the country have a chance to go to the International Space Station to fight against 16 the country and the Tiangong? What little secrets are hidden in the Heavenly Palace?

The Tianhe core module of China Space Station has been successfully put into orbit, and our Tianzhou-2 cargo spacecraft has also completed a thrilling eight-hour docking with the core module. China Space Station mainly includes the core module, the experimental module of Meng Tian and the experimental module of asking for heaven, as well as manned spacecraft and cargo spacecraft, which is our courier brother Tianzhou II cargo spacecraft. The composition of the total * * * five departments has now completed two, which can be said to be half realized.

So, White Wolf has a few questions here. First, the Tiangong Space Station was independently completed by China, while the old-timer International Space Station was completed by 16 countries. Is there a chance for one country to win against 16 and Tiangong? Second, the Tianhe core cabin launched by China Space Station is much smaller than the International Space Station. Can Tianhe core module be used for such a huge difference?

Third, in the introduction of China Space Station, there are many new technologies, such as a new robotic arm and a new regenerative life support system. So how do they crawl and move on the space station? How can the new regenerative life support system reduce the drinking water supply by more than 80%?

With these questions, let's see if the Tiangong Space Station built by China alone can shake the status of the international space station built by 16. Let's start with the first question. 1 Does the country have a chance to win 16? This question is actually very simple, and the answer is naturally assured.

In terms of quantity, it does sound that the China Space Station is a bit weak, but on the other hand, we independently built the China Space Station. No matter what materials and technologies are used in the construction, these are problems that we have to solve internally. However, the International Space Station is different. If 16 countries jointly build, it will naturally be distributed, which is equivalent to the company's share. You can only get as much bonus as your investment. If you want more, it depends on whether other countries agree or disagree.

In addition, the space station was originally used to carry out various scientific experiments and complete space exploration, and various scientific experiments have great influence on the development of the country. I paid for the construction of the International Space Station, but in the end, you made a lot of money, and everything was ahead. Do you think the other partners can let go? Therefore, there is a serious problem in the International Space Station, which is "fair distribution".

This problem does not exist in China Space Station, which is built by ourselves, so all kinds of experiments done in it also need our audit. Just like the news that the United States was shut out of China Space Station before, it doesn't matter who you are if you don't meet China's own technical standards.

Moreover, when it comes to status, the International Space Station is a dying hero. Even though it once shone brilliantly, it is now near dusk, and the China Space Station is just a fledgling young talent, and there is still plenty of time left for Tiangong. It is only a matter of time before the status of the International Space Station is shaken.

Then let's talk about the second question. Is the space station in China enough? Especially after the new situation of China's space station was exposed one after another, people's doubts about whether China's space station is enough deepened. Because the Tiangong is equipped with too many things, such as microwave ovens, refrigerators, drinking fountains, folding tables and other furniture, as well as various space runways, space bicycles and anti-fatigue devices.

In fact, here, we really don't have to worry about the shortage of Tiangong-1 and Tiangong-2. First of all, compared with the seemingly crowded space of Tiangong-1 and Tiangong-2, the Tianhe core cabin is really enough. First of all, the space for astronauts to live in Tianhe core cabin is about 50 cubic meters, and the space of other cabins, the activity area is at least 1 10 cubic meters. The International Space Station looks much bigger than the core module, but as we said earlier, it was built by 16 countries, with an average of 16, so there is not much space left for each country.

Let's talk about the third issue, the use of new technologies and equipment. Maybe everyone will think about what a new type of mechanical arm is and why it should be used to build a space station. But in fact, the mechanical arm is very important for docking between cabins. As we all know, the Tiangong was not built at one time, but was made up of several cabins, so it is very difficult to run in space. Docking is more difficult now, especially the interface.

Both the core module and the experimental module are large modules of 20 tons, and there is no horizontal docking interface between them. If forced docking, it means that the experimental cabin needs dynamic docking, that is, axial docking is changed to lateral docking. However, this process is full of dangers and the situation is better. The instability of space station may cause serious damage to the structure of space station. What are we doing? The purpose of the mechanical arm is coming, similar to the lever principle. After direct docking, I'll take you there, and there will be no problem.

Moreover, the role of the mechanical arm is not limited to this. Smaller ones can receive express delivery at the space station, and older ones can help astronauts work. As for how it crawls, it's actually very simple. For example, in the process of climbing a tree, one foot stands firm, and the other foot can relax to find the next landing point. The mechanical arm is the same, and so is the docking interface on the core module. After the two ends are firmly connected, you can enter the next interface, thus realizing crawling.

As for how the new regenerative life support system works, it is even simpler. The water vapor exhaled by astronauts can be recovered with condensed water, and urine can also be recovered and purified, so that drinking water and domestic water are available. In addition, when the carbon dioxide exhaled by astronauts meets the hydrogen produced by oxygen electrolysis, it will have a chemical reaction and become oxygen, so they can breathe.

Some people may say, why not supply directly? All supplies in space must be transported from the ground, such as the materials transported by Tianzhou-2 this time. Russian cargo ships are so tired that they were supposed to deliver goods, but if we can solve some of them in space, the ground transportation will not be so urgent.
