Shenzhou 14 manned flight mission With the successful landing of the return capsule, three astronauts Chen Dong, Liu Yang and Cai Xuzhe returned to Earth safely after 183 days of space flight. The Shenzhou 14 crew is called the "busiest crew" because they have been in a 6-month space flight and the mission rosters are still very close and have completed many firsts.
Three astronauts welcomed the arrival of the Wentian Experimental Cabin and Mengtian Experimental Cabin in orbit. They also became witnesses and even participants in the T-shaped configuration of the Chinese space station. At the same time, they also conducted three spacewalks, the best of China's previous manned flight missions.
and a space lecture was conducted in the Wentian Experimental Cabin as planned, allowing us to witness the real scenes in the Wentian Experimental Cabin with our own eyes and also bring interesting experiments to the children. As witnesses to the first on-orbit mission in China, they met with the Shenzhou 15 astronaut and flew together for 5 days. The scene of the six-person space mission will surely be remembered.
According to the plan, the Shenzhou 14 manned spacecraft evacuated the space station at around 11:00 on the 4th. After about 9 hours of rapid return, it landed safely at the Dongfeng landing site.
The moment the return capsule of the Shenzhou 14 manned spacecraft landed, the host of the live broadcast asked whether the return capsule was upright or inclined? Soon the search and rescue personnel arrived at the scene. We saw that the return capsule of Shenzhou 14 showed a horizontal posture, and the vertical state that many netizens hoped to see did not appear.
You should know that when the Shenzhou 13 manned spacecraft returned to the ground, a vertical state rarely appeared. This state is very difficult. From Shenzhou 5 to today's Shenzhou 14, there were only two times when they returned to the ground. The first was the Shenzhou 6 manned spacecraft in 2005, and the second time was the Shenzhou 13 manned spacecraft.
You should know that this perfect state is not so easy to occur, and many times the return capsule is inclined. First of all, when the astronauts returned to the upright state of the capsule from the comfort angle, the three astronauts were lying at the bottom of the return cabin, which was both comfortable and safe, but one disadvantage was that it was more difficult to leave the cabin.
This time, the Shenzhou 14 manned spacecraft's return capsule tilted to a horizontal posture after landing on the ground. This is also the most common posture after landing on the ground of the return capsule. The astronaut's attitude in the cabin may not be very comfortable, but may be in an upside down state.
But why do experts say that for this mission, the return capsule is horizontal, but it is the best perfect posture?
In fact, the return mission of the Shenzhou 14 manned spacecraft is slightly different from that of the Shenzhou 13. The Shenzhou 14 manned spacecraft is separated from the space station at 11 o'clock, and it takes about 9 hours to go through the rapid return technology. In the end, Shenzhou 14 safely landed on the Dongfeng landing site at around 8:10 pm.
Shenzhou 14's return journey is considered to be the darkest, coldest, most complex and most difficult in China's manned space flight history. The sight will definitely be affected in the middle of the night, and it will be even more difficult to search the return capsule.
Secondly, the extremely cold environment is also a challenge for the astronauts returning to space. After all, after six months of space flight, the astronauts' bodies are already relatively weak. If they still have to freeze in an environment of minus 15 degrees Celsius for a period of time, naturally, such things will not be allowed to happen.
In order to try to compress the return capsule door and the astronauts entered the medical supervision and medical insurance vehicle, many changes have been made in the process.
The most obvious thing is that the interview time has been shortened, unlike the Shenzhou 13 astronauts who returned to the ground, and then interviewed in turn. However, after Shenzhou 14 returned, the astronaut received a brief visit after leaving the cabin, and was soon sent to the medical supervision and medical insurance vehicle, followed by the next astronaut leaving the cabin. Therefore, no one could see a group photo of the three astronauts sitting on their chairs after leaving the cabin.
The attitude problem in the return capsule affects the time spent on the astronauts leaving the cabin. For example, when the return capsule is upright, the astronauts leaving the cabin requires staff to build a bench, which is very slow.
When the return capsule is in a horizontal attitude, the time it takes for the astronaut to leave the capsule will be shorter. For example, the process of exiting the cabin of Shenzhou 13 lasts 50 minutes, while the process of exiting the cabin of Shenzhou 14 is completed in about 20 minutes.
This shortens the time for astronauts to stay outdoors. After all, in the extremely cold environment at night, astronauts need to transfer to the medical supervision and medical insurance vehicle as soon as possible. The temperature in the vehicle can be guaranteed to be above 25 degrees Celsius. Why not eat delicious food?
Therefore, it is said that the Shenzhou 14 return capsule will show a horizontal posture after landing, which is the best perfect posture for this mission.
