With the end of the Shenzhou XIII manned spacecraft mission, the current Chinese space station assembly is only "one cabin and one ship", including the Tianhe core module and the Tianzhou-3 cargo spacecraft, and the Chinese space station assembly is temporarily unguarded for a short time. The most recent launch mission of the Chinese space station was in May, and the Tianzhou-4 cargo spacecraft is currently waiting to depart at the Wenchang Cosmodrome and the Long March 7 Yao-5 carrier fire, bringing supplies for the Shenzhou 14 manned spacecraft for six months.
Remember that in the early days of the preparation of the International Space Station, China was bent on joining the project of the International Space Station, but it was strongly opposed by the United States, and China was not allowed to participate in the International Space Station project on the grounds of technology and funding.
In fact, this is a yang plot, is a kind of technical blockade, but the United States can not figure out how, China's development in the field of space is thick and thin, since it can not join the national space station, then build its own space station, in April 2021 with the launch of the Tianhe core module into orbit, but also officially announced the Chinese space station it came, followed by Tianzhou II, Shenzhou XII, Tianzhou III and Shenzhou XIII have completed the established tasks, but also means the perfect end of the key technology verification stage of the Chinese space station.
Six launches completed the construction of the space station
With the safe return of the three Shenzhou 13 astronauts to Earth, the key technology verification phase of China's space station construction means a successful conclusion. At the same time, the Chinese space station has officially entered the construction stage, so the key technology has been verified, and in the remaining time of 2022, the Chinese space station will have 6 launch missions.
In mid-to-early May, the launch mission of Tianzhou 4 will be carried out, and the so-called soldiers and horses will not move the grain and grass first, and it will bring sufficient supplies to the space station. Previously, Tianzhou-3 has completed the transposition rendezvous and docking action in orbit, moving from the backward pair interface to the forward pairing interface to make way for the upcoming Tianzhou-4 cargo spacecraft.
In June, the launch mission of the Shenzhou 14 manned spacecraft will be carried out, and like the Shenzhou 13, the three astronauts will fly in orbit for 6 months, and the mission of this group of astronauts will be relatively heavier.
Immediately after that in July, the "Q&A" experimental module will be lifted into orbit, first to the forward docking interface, and then to the horizontal rotation with the assistance of the robotic arm, and finally the experimental module will reach the radial berth. In October, the "Dream" experimental module will be launched into orbit, followed by the Manned Launch Mission of Tianzhou 5 Cargo Spacecraft and Shenzhou 15, which will be carried out in 2022, when the Construction of the Chinese Space Station will be completely completed and the official operation stage will enter 2023.
Shenzhou 14 astronauts have determined, will there be Yang Liwei?
At present, according to the news of the China Manned Space Engineering Office, the Shenzhou 14 manned spacecraft and the Shenzhou 15 manned spacecraft that are ready to be launched in 2022, the list of 6 astronauts in the two astronaut crews has been confirmed, and they are currently carrying out corresponding training.
Many people are speculating, who may be the crew of the three astronauts of the Shenzhou XIV manned spacecraft? Will there be Yang Liwei? Although the Shenzhou 14 astronaut crew has been determined, but there is no specific candidate, many people speculate whether it can be Yang Liwei?
Yang Liwei was the first person in China's manned space flight, and on October 15, 2003, Yang Liwei entered space for the first time on the Shenzhou 5 spacecraft carried by the Long March 2F rocket. At present, Yang Liwei is the deputy chief designer of China's manned space project, and Yang Liwei is also an astronaut in service, one of the first batch of astronauts in China, and is still training to prepare for entering space again.
However, the general view is that yang Liwei will not enter space again without special circumstances, after all, the number of newcomer astronauts is also quite large, Yang Liwei's stick should have been handed over long ago, and it is also a chance to give young and inexperienced astronauts a chance to practice in actual combat, so it is said that the Shenzhou XIV manned spacecraft enters the space station, and Yang Liwei should not enter space again.
Thrilling life and death for 26 seconds, the reason is heart-wrenching
Yang Liwei is the first person in China's manned spaceflight, and the first Chinese to fly out of the earth and into space, which is of great significance to China's manned spaceflight project. After all, before there is no actual battle, even if the preparation is sufficient, it will not be possible to reach a hundred percent situation.
Yang Liwei recalled that he had experienced 26 seconds of life and death in the process of entering space, and with the liftoff of Shenzhou V, Yang Liwei encountered a low-frequency vibration of about 8 hertz in the ascent stage, which was something that he had never experienced in training.
The low-frequency vibrations of the spacecraft and rockets made Yang Liwei extremely painful, and even the internal organs resonated, and the whole body was completely uncontrollable, very painful, he once thought he was going to die, and the whole process lasted for 26 seconds. According to Yang Liwei's recollection, it was a feeling of imminent death at that time.
This is really very difficult, and it is precisely because of this experience, so that researchers to obtain first-hand information, technical rectification, the follow-up manned spacecraft will not have a similar experience, can only say that Yang Liwei's life and death of 26 seconds of experience is heart-wrenching, but fortunately we keep the cloud open to see the moon clear, the Chinese space station is coming, in 2022 will also completely complete the construction work.
Say at the end
With the completion of the Chinese space station into the formal operation stage, there will be astronauts stationed in the future, and the flight cycle is also a regular 6 months, so it is said that in the future, Chinese astronauts will have the opportunity to enter the Chinese space station. The older generation of astronauts are the leaders, passing on their experience to a new generation of astronauts, and eventually every astronaut will become the backbone of China's aerospace.
