China's space station has achieved a breakthrough layout in experiments! Shenzhou-18 astronauts Ye Guangfu, Li Cong, and Li Guangsu have started a new round of extravehicular exposure experiments.
At the same time, the news about the Shenzhou 19 manned spacecraft is also hotly discussed, so let's take a look at these breakthrough missions first, and then take a look at the Shenzhou 19 manned spacecraft.
Indeed, the continental space mission is like this, and in the rapid implementation of the mission step by step, it is also expected to achieve breakthroughs in all aspects.
Shenzhou 18 layout major experiment! What exactly is the use?
For this experimental mission, we have also seen that it is the "extravehicular exposure experiment" carried out by the mainland, and the three astronauts Ye Guangfu, Li Cong, and Li Guangsu have achieved a breakthrough and completed the task of leaving the material extravehicular exposure experimental device, so the major experiment of the layout has been completed.
At the same time, in addition to the layout of this, the three astronauts also carried out medical rescue on-orbit training, mass measurement and other tasks, all of which were successfully completed.
I have to say that although the three astronauts have not been on the mission for a long time, they still bring a lot of surprises to everyone. So what exactly is the use of this "extravehicular exposure experiment"?
If you know more about China's manned space mission, you know that when the Shenzhou 17 manned spacecraft mission of the mainland was launched, the first batch of extravehicular exposure experiments were carried out, which included two categories: non-metal and metal, with a total of 407 material research results.
Among them, non-metallic materials include memory polymer materials, lunar soil reinforcement materials, solid lubrication and gel composite lubricating materials, etc., and metal materials include magnesium alloys and porous copper materials.
After the extravehicular exposure, the change process of materials can be found through the different environments, and breakthroughs in material science can be achieved, which is the biggest effect.
Because the mechanism of material structure damage, performance decline and functional failure and destruction can be revealed through exposure experiments, only by finding these change laws, the material can be changed, and then used, there will be no problems in the future, this is the benefit, this is the role of the major experiment of Shenzhou 18 layout.
Therefore, it is expected that this batch of experimental results will be produced as soon as possible, but for the exposure of extravehicular experiments, it does take time, and it should be retrieved after 1 year, because the first batch of experimental results retrieved by the Shenzhou 17 astronauts is a mission that will be carried out after a year of in-orbit experiments, which is the approximate situation.
The Shenzhou-19 manned spacecraft mission has also been hotly discussed
That's right, under the mission of the Shenzhou 18 manned spacecraft, the mission of the mainland Shenzhou 19 manned spacecraft is also hotly discussed.
Of course, this is one of the key tasks in 2024, and it is expected to be carried out in October 2024, because the mainland announced a time node, that is, in late October, the Shenzhou 18 astronauts will return to the Dongfeng landing site, and the hot discussion about Shenzhou 19 is mainly about astronauts.
That's right, the mainland has officially announced many times that the Shenzhou-19 astronaut crew has been determined and is training, and for the training of these crews, the mainland is also improving its strength.
For example, when the Chinese space station encounters an unexpected situation, the crew can be allowed to carry out the mission directly, without the need to send an astronaut crew to carry out such a mission.
On the Shenzhou 17 mission, in fact, everyone should also see such a point, that is, the astronaut crew is all "pilots", in fact, it may be a crew specially formed to repair the solar wing of the continental space station.
Of course, this is explained in terms of nature, just take a look.
However, if the same situation is encountered in the future, the mainland will not operate in this way, and every astronaut will have enhanced training, and he can directly deal with it.
Therefore, the astronauts of the Shenzhou-19 manned spacecraft are doing these tasks.
However, although mainland officials have repeatedly emphasized the determination of the astronauts of the Shenzhou-19 manned spacecraft, the biggest point is that the specific list of astronauts has not been announced, because the mainland wants to take secrecy measures.
Previously, the Shenzhou 18 astronauts were also like this, and they have always said that the astronauts have been confirmed, but the detailed list has not been announced.
Therefore, many people see the certainty, not to mention the list of astronauts, I can only say, don't get excited, you don't know, it doesn't mean that the space center doesn't know, the mainland will announce it before the mission.
Because as long as the list of astronauts is announced in advance, the outside world may have an impact, and even affect the people around you.
Those who understand should also be able to see that after each announcement of astronauts, are the people around them reported, and this may also cause interference to astronauts who are trained in closed mode?
Therefore, secrecy is necessary, and the later you know, the better, and there are many aspects involved in China's aerospace field, which also need to be kept secret, and this is the general situation.
The astronauts confirmed that the spacecraft was also ready and on standby
That's right, under the Shenzhou 18 manned spacecraft, the mainland Shenzhou 19 manned spacecraft is also fine, and it is at the mainland space launch site, this is because of the problem of China's space strategy, every time it performs a mission, it is a "double spacecraft".
One of the spacecraft is on a mission, and another spacecraft is to do a "standby rescue" mission at the launch site, this mission is for the sake of the safety of the astronauts, as long as the astronauts encounter an emergency in the process of carrying out the mission, the mainland can launch the standby rescue spacecraft, and then pick it up.
The benefits of this can also be contrasted, the spacecraft of the International Space Station was hit by space particles, and as a result, the astronauts on it could not return, so they could only wait for the spacecraft on the ground to be redeveloped, assembled, etc., before being launched and brought back. And this time stage is not friendly to astronauts.
If the mainland encounters such a situation, then there is no need to wait for any time at all, and the standby rescue spacecraft will be launched directly and it will be directly picked up.
Moreover, it doesn't matter if it is not needed, the ship can be directly turned to the next mission, so it is necessary to carry out such a mission.
Finally, it is also expected that the astronauts of the Shenzhou-18 manned spacecraft, Ye Guangfu, Li Cong, and Li Guangsu, will complete all the designated tasks and then return to the ground.
Of course, there is a very much looking forward task for the crew to change the crew, that is, the astronauts go out of the capsule to upgrade the space station, this task is also the first time that the mainland space station has carried out it, the mainland has not done such a mission before, I hope it can be completed quickly and well, this is the general situation.
