The astronauts of Shenzhou-18 and Shenzhou-17 have completed their rendezvous in space! China's new round of manned spacecraft missions has also achieved complete success, and it has to be said that China's space station missions have entered a stage of high frequency.
At the same time, China's space station has also ushered in a different situation, and China's space station will continue to expand in the future, showing the situation of China's "space home port".
So what's going on, let's explain it in detail.
Twin Ships! Twin Commanders, 6 people flying together!
That's right, after Shenzhou-18 astronauts Ye Guangfu, Li Cong, and Li Guangsu entered China's space station, they and Shenzhou-17 astronauts Tang Hongbo, Tang Shengjie, and Jiang Xinlin had already completed their rendezvous.
The two spacecraft are the Shenzhou 18 manned spacecraft and the Shenzhou 19 manned spacecraft (limited to manned spacecraft), and the dual commanders are Tang Hongbo and Ye Guangfu.
Therefore, at this time, the Chinese space station is really lively, and it is also a historic scene of the Chinese space station, and it is the most critical moment for these six astronauts to perform tasks in orbit simultaneously.
Of course, this time the space rendezvous of the Shenzhou 18 manned spacecraft is also the fourth "space rendezvous" of the mainland's Chinese space station, and it is also the youngest crew rendezvous, with the average age of Shenzhou 17 and Shenzhou 18 being less than 40 years old, which is also a historic scene since the construction of the mainland space station.
The six astronauts also took a "family photo", which will encourage the mainland to continue to carry out future space missions.
The next most critical task of the two crews is to carry out the "handover", and after about 5 days of synchronous flight of the six people, the Shenzhou 17 astronauts return to the Dongfeng landing site. So what are the tasks to be handed over between the astronauts?
First, there are a large number of different types of materials stored on the space station, including tools related to maintenance and operation, as well as food and clothing needed by astronauts and test samples needed for application systems, which need to be handed over.
Second, the huge material handover, we use the storage space designed by the space station to classify and store, and the astronauts need to correspond to the handover one by one.
Third, some daily maintenance work in the space station, including the specific operation of the work project, needs to be handed over.
In addition to these, the astronauts' work and life experience in space also need to be handed over, such as the Shenzhou 17 astronauts completed the first out-of-cabin activity of the continental space station and carried out the maintenance of solar wings, which is very good.
After handing over to the astronauts of the Shenzhou-18 manned spacecraft, if such a situation is encountered in the future, it can be directly processed in orbit without the need for a new crew to solve it.
Therefore, the astronauts still have more handover tasks and are relatively busy. After the handover is completed, it is returned, and it is explained to you above.
How long is the precise return time of the Shenzhou-17 astronauts?
First of all, let me explain that when the Shenzhou 17 astronauts return this time, they will bring rich results, of which the most concerned is nothing more than "experimental results".
Indeed, during the orbit of the Shenzhou-17 astronauts, the experimental results of the Chinese space station were recovered - in close cooperation with ground researchers, the first batch of extravehicular exposure experimental material samples were successfully retrieved, and the first batch of material exposure samples included non-metal and metal, a total of 407 pieces.
These samples will be disassembled and stored by the astronauts, and this part of the experimental results will be brought back to the ground when the Shenzhou-17 astronauts return, and then handed over to the mainland ground science team for relevant research to achieve a breakthrough in materials science.
Therefore, many people say that they don't know what China's space station is built for, I don't know if it is connected to the Internet at home, or whether it is a monster, this is the function, doing space experiments, and the results related to everyone's life. Then, after those who don't know see it, don't say they don't know what to do.
As for the return time of the Shenzhou-17 astronauts, according to the NOTAMS released by the Lanzhou Flight Information Region, the return capsule of the Shenzhou-17 manned spacecraft is scheduled to return to the Dongfeng landing site from 17:20 to 17:50 Beijing time on April 30.
If you are interested, you can pay more attention. Yang Liwei also explained before that if time permits, he may personally pick up the Shenzhou 17 astronauts to return, which is the general situation.
China's "space home port" is also coming
That's right, China's "space home port" is also coming, to achieve a major upgrade of the existing space station, according to the plan, in the future we will build a combination of 180 tons and six modules, that is, from the existing three to six cabins.
According to Zhang Qiao of the China Academy of Space Technology, the mainland is developing the expansion interface of the Tianhe core module and the Wentian experimental module to carry large external payloads, and the inflatable sealed cabin is also under development.
After the expansion of China's space station, it is likely that more spacecraft will "fly in orbit with China's space station and receive in-orbit services."
To put it simply, China's space station has become a "space home port", a hub area with a central core, and other spacecraft, after the launch of the module segment, may not need to fly directly in the future, but fly in synchronous orbit with the Chinese space station.
And it has the ability to perform and complete the mission alone, and in the case of energy supply, support, etc., the docking between the space stations can be realized, so as to turn it into a flexible "space home port", and the rest of it is similar to the aircraft carrier you see.
Therefore, the space station at that time was really completely different, and the continent of the aircraft was already implementing it, that is, a definite project. The benefits of such construction actually solve many people's worries.
That is the mainland - not to allow foreign astronauts to fly, but also to agree, India, Japan, Italy, France, Spain, the Netherlands and other 17 countries to join, many people are worried about whether it will bring damage to the Chinese space station.
However, as long as the mainland establishes a sub-module, it can be directly arranged to carry out the mission in the sub-cabin, and there is no need to contact the Chinese core module.
So, in this way, the sooner the plan is implemented, the better, then everyone will have no worries, and they can also conduct mutual scientific experiments and share achievements, so why not?
Therefore, it is expected that the construction of China's space home port will be completed as soon as possible, and there are too many benefits, so that China will have greater achievements and breakthrough development in aerospace.
