China's Tianzhou-7 cargo spacecraft is rumored to be launched on 15 January, and it is getting closer and closer in terms of time.
This is also the "first mission" of the mainland's manned space project, in 2024, the mainland will carry out four missions, namely the Tianzhou-7 cargo spacecraft, the Shenzhou-18 manned spacecraft, the Tianzhou-8 cargo spacecraft and the Shenzhou-19 manned spacecraft.
Therefore, seeing the implementation of the Shenzhou 18 mission, many people are also raising questions, that is, whether foreign astronauts are really coming?
It is rumored on the Internet that Tianzhou-7 will be launched on January 15!
Indeed, there is no more detailed explanation except for the news that the mainland's Long March 7 Yao-8 carrier rocket will carry out the final assembly and testing work of the launch site together with the Tianzhou-7 cargo spacecraft, which has arrived in advance, and will be launched in early 2024 - January.
No, foreign media have reported that China's Tianzhou-7 will be launched on 15 January, is this time accurate? Is it that the mainland space mission has been leaked again?
In fact, this is not an accident, and when the mainland performs an important mission of a manned spacecraft, it is necessary to make a record explanation of the relevance.
Moreover, as an important project of China's space station, in fact, the time node will be announced very early, and at the same time, on the launch of the Tianzhou cargo spacecraft, the mainland also pays attention to the implementation of the "window period" mission. Just like when the Tianzhou-6 cargo spacecraft was executed, the mainland implemented a "zero window" launch, which is very powerful.
This time frame is determined by comprehensively considering various factors such as the nature of the mission, the arrangement of the launch mission, and the weather conditions in the field, and its length and accuracy vary greatly from mission to mission, with some calculated in days, some in hours, and some in minutes and seconds.
Therefore, when the Tianzhou-7 cargo spacecraft performs its mission, it also has a "window period" explanation.
It is rumored that the launch will be carried out on January 15, in fact, it is not a big problem, but at a specific time node, it may also make corresponding "fine-tuning", if it really encounters a more important problem, it will definitely be postponed.
At the same time, combined with the data of all the transit of China's space station, there is indeed a good node on January 15, that is, the altitude angle appeared 81 degrees on January 18, which is also in line with the basic information of the launch during the window period.
If you are specific, interested friends can calculate it according to the detailed orbital data released by the Chinese space station.
Although the specific situation of the mainland Tianzhou-7 has not yet been announced, the Tianzhou-7 is one of the cargo spacecraft that belongs to the mainland's Tianzhou-6 to 11 cargo spacecraft, so the strength is the same, and this has not changed much, and it is bound to be the strongest cargo spacecraft on the mainland and one of the cargo spacecraft with the strongest cargo capacity in the world.
With a length of 10.6 meters, the cargo capacity can reach 7.4 tons, and the effective loading volume can reach 22.5 cubic meters, which is illustrated by the Tianzhou-6 cargo spacecraft.
It can be seen that the Tianzhou-7 cargo spacecraft is indeed not simple, and the specific cargo list will definitely be explained by the mainland when it performs the mission.
Of course, this batch of cargo spacecraft will definitely bring a lot of gifts to the mainland Shenzhou 17 astronauts Tang Hongbo, Tang Shengjie, and Jiang Xinlin, after all, there is still a Spring Festival in space, this is the general situation.
After the Tianzhou-7 cargo spacecraft, Shenzhou-18 will also be launched
That's right, after the Tianzhou-7 cargo spacecraft, the implementation of the Shenzhou-18 mission is the most important, and for the Shenzhou-18 manned spacecraft, it has actually been built, just in the mainland launch site.
What is the situation in its current state of being "on standby for rescue"? Don't be nervous, this is the mainland's space strategy, which is specially prepared for the safety of astronauts.
When Chinese astronauts perform missions in space, if there is an emergency, the mainland can launch the Shenzhou 18 spacecraft, implement the rapid rescue mode, and bring the three astronauts back to the ground.
The astronauts above do not need to wait, many people should have seen before, the International Space Station return spacecraft suffered the impact of space junk, and as a result, there are not many spaceships on the ground, so the astronauts can only wait for the next spacecraft to go up before they can pick it up.
In this waiting process, it is really too long, and if China encounters a similar situation, it does not need to wait, just launch the spacecraft into space, which is the benefit of the standby spacecraft.
Then Shenzhou 18 will be executed after the Tianzhou 7 cargo spacecraft, will there be foreign astronauts?
Indeed, the participation of foreign astronauts in China's space station is already "boiling", because when the mainland Shenzhou 17 manned spacecraft mission, the space center publicly stated that it officially invited foreign astronauts to Tiangong, and it is also ready, and it is ready to invite foreign astronauts to participate in the mission of China's space station.
Therefore, many people are hotly discussing whether there are foreign astronauts in Shenzhou 18, and the most critical point of many people arguing is "which country".
Especially after the mainland announced the list of 17 countries to join China's space station.
Including - Japan, Switzerland, Poland, Germany, Italy, Norway, France, Spain, the Netherlands, India, Russia, Belgium, Kenya, Saudi Arabia, Mexico, Peru and other 17 countries to join the Chinese space station.
As a result, many people are arguing, there are many unfriendly countries in it, whether it should not be allowed to enter the space station, similar to Japan, India and other countries, are against entering. There is even a discussion that the first person from the country to enter the Chinese space station was - Japan, really?
In fact, for Shenzhou 18, from my personal point of view, there may be no foreign astronauts at all, let alone Japan, which is unlikely.
Why is it unlikely that the Shenzhou-18 manned spacecraft will have foreign astronauts?
Judging from the mainland's announcement of the invitation plan, it is a trend for foreign astronauts to join China's space station, and there will definitely be one in the future. However, foreign astronauts joining the Chinese space station does not mean entering the space, just as the Chinese space station has high Chinese requirements, and the operation interface and system inside the space are all taken in Chinese.
If foreign astronauts want to join China's space station and do not learn Xi Chinese well, will they be able to carry out the mission?
At the same time, after the selection of foreign astronauts, various trainings will be carried out, from the Shenzhou 17 mission to the Shenzhou 18 mission, to be familiar with the Chinese space station, and to learn Xi large-scale Chinese, instructions and other issues, this is about 6 months, is it a bit short?
Therefore, I personally think that this possibility is not very likely, and the possibility of Shenzhou 19 still exists, specifically, it will be seen later when the mainland announces the list of astronauts of the Shenzhou 18 manned spacecraft.
