1, which lasted for three months and laid the foundation for the future.
As we all know, China has finally established a space station beyond the earth after difficulties, and its great value goes without saying. Therefore, for China astronauts, this mission is to debug and lay the foundation for the use of the space station in the next 20 years.
In other words, it is not too much to stay in the orbit of the space station for another three months. You must know that the astronauts finally went to the space station, and the task is not complicated. Can you be meticulous! At the same time, the coordination of air and space integration and land and air integration cannot be optimized as much as possible!
2. Return to the National Day, the time is not fixed.
Therefore, if the installation is carried out according to the original plan, they must return according to the instructions three months after entering the space station. We should know that although the China Space Station has been in operation, it was only a key step in the development of the space station at that time. In the future, various problems such as the docking of supply ships and the rotation of astronauts still pose challenges to China astronauts in the future.
Therefore, astronauts as soldiers must complete the task of "laying the foundation stone" for the space station within a limited space time, otherwise their lives will face great risks and the operation of the space station will be affected by far-reaching hidden dangers. You know, the universe faces too many unknowns.
To sum up, the operation of the space station must be completed within three months. That is to say, on the eve of the National Day, that is, in mid-September, these brave people will leave the space station, and after the related construction of the future space station is completed, they will take the recoverable spacecraft, enter the earth orbit and return to the earth. And this seems to be a few words, and the disaster behind it is unpredictable! So the specific time for them to come back can only be tentative.
