Everything is ready!Waiting for Shenzhou 18th astronauts to return.
Of course, at this stage Shenzhou 18th astronauts still perform task transfer in the space station. According to the time stage, it is expected to be transferred around for about 5 days and then return to the earth.
However, from the new round of news from the Dongfeng landing field, this time the Eighteenth Aerospace Members will return in the early morning,Isnt it difficult for the ground personnel to search for rescue for astronauts?
How to guarantee it?After the astronauts returned, they would be carried away. Why?Lets take a look at in detail below.
OK!Shenzhou 18th astronauts have prepared to evacuate
Yes, although Shenzhou 18 astronauts and Shenzhou 19 astronauts are still in space, my country And 6 people fly together.
It may still be transferred to some tasks, but for the preparation of returning work, my country has clearly stated that Shenzhou 18 Aerospace The staff is ready to evacuate, and everything is waiting for the time of the time node.
In terms of time, my country will enter the Shenzhou 18 astronauts return process in the early morning of November 4.
Of course, many people may say, why not choose during the day, when Shenzhou 19th is launched, many people are sleeping. When they wake upThe 19th astronauts Cai Xuzhe, Song Lingdong, and Wang Haoze had already taken the spacecraft to the space station.
So, if you return during the day, can you still see it?In fact, whether it is day or night, as long as you want to see it, it must be seen. The live broadcast process of the spacemen returns in my country will be normalized. Generally, there will be no change.
However, for the return of the astronauts, it does not mean that when it returns, it will return, because the return time is based on the node of the space station task.
Just as: my country executes Shenzhou 19 manned spacecraft launch, which needs to be fixed at 4:27 in the morning. This is because of our country The window period of the aerospace mission is at this time, so the task is performed at this time.
Then when the Shenzhou 18 astronauts were selected at this time, it was also determined by the space station running track and other issues.
So, it is not to be changed casually. This is relatedInstead, it is the reason for bringing some adverse effects.
So, Shenzhou 18 astronauts are ready to evacuate, and the next step is to wait for the task node, and then return to the Dongfeng landing field.
How difficult is it in the early morning?What are we doing in my country?
It is true. For returning in the early morning, there must be a lot of challenges faced by search and rescue personnel in my country. The two most direct points are the poor light in the early morning. It is a period of cold air, and the temperature of Dongfeng landing field is relatively low.
So, we must prepare these two aspects, and just happen, my country is also targeted.
Of course, this is not the first time that my country has conducted a search and rescue task of the night -wind landing field at night. He also carried out such tasks when the Shenzhou 14 astronauts returned.
What are the preparations for our country to meet this difficult challenge task?Mainly two aspects.
First, low temperature preparation, according to the meteorological data statistics of the landing field over the years, the average temperature in early November was about 1.5 degrees Celsius, and the extreme lowest temperature was minus 14.4 degrees Celsius.
So, in order to welcome the Shenzhou 18th astronauts multiplication group, my country has already rescued the astronauts in the warmest way to prepare sleeping bags, covered blankets and other cold. Materials, at the same time to maintain the medical insurance vehicle, can also provide astronauts with suitable temperature and medical insurance venues under low temperature conditions.
Second, search and rescue preparation, at the moment when the astronauts return to the earth- , And the "black paint" that the astronauts can see at the time of the cabin, in my country, follow the idea of making the rescue scene bright.
Make a variety of lighting equipment 4 types and 18 sets, which further improved the landing site lighting guarantee method on the basis of Shenzhou 14 night search and rescue.When it is, it will be "light".
Under the comprehensive preparation, the search and rescue power and equipment of the Dongfeng landing field in my country are in a good state, and the conditions for performing search and rescue tasks have the conditions for performing search and rescue tasks. This is the approximate situation.
Why should the astronauts return?
Indeed, for the astronauts who perform space mission in my country, it is a more normal thing to carry it. EssenceAnd this time, the Shenzhou 18th astronauts multiplied by group, and it must be indispensable. So what is the reason?
In fact, the most direct reason is that living in space for too long, the body of the astronauts will change, the astronauts will change, and the astronauts willAfter returning to the ground, the body systems from top to bottom must adapt to the environment of gravity, such as vestibular system, skeletal muscle system, cardiovascular system, balance function, muscle coordination, including changes in the distribution of the entire body fluid.
In this case, then it must not let the astronauts walk directly. In this case, it may directly bring physical damage.
So, in order to help 3 astronauts adapt to the gravity environment of the earth faster, ground staff should start a seriesFunctional recovery.
Of course, for the entire recovery of the astronauts, this takes a certain time.The recovery work is carried out in three stages:
In the first stage, the restoration stage isolates to promote basic functional recovery.The time is 3-4 weeks, mainly to eliminate the adverse effects of physical function during flight.
In the second stage, it takes 4-5 weeks, mainly for the recovery phase of recovery to ensure comprehensive physical and mental recovery.
The third stage, which takes about 4 months, is mainly to restore the observation phase, and various types of training begin to carry out.
After half a year of recovery, the astronauts transferred to the normal task training period. After the recovery is complete, if there is a task, my countrys astronauts will continue to perform the task, fly again, enter again, enter China Space Station, this is the approximate situation.
Therefore, the work of the astronauts is still very complicated. Each task is a breakthrough in its own, but when there is no task, you must also strengthen your training and comprehensively comprehensively.Preparation for the next task is to do this back and forth. As long as you have no retirement, the future tasks may be executed at any time. This is the rough situation.
