On October 16, 2021, China's Shenzhou-13 will carry three astronauts on board, and Shenzhou-13 is also the mainland's third manned space mission.
There is also a list of three astronauts related to this mission, namely Zhai Zhigang, Wang Yaping and Ye Guangfu, among which there is also a beautiful astronaut, she is Wang Yaping.
And this time the Shenzhou 13 space mission will also be different from the previous one, because there is a very special mission, that is, the "Tiangong Science Popularization Space Lecture" by Wang Yaping, which is also the first course carried out by the mainland in space.
And what kind of challenges will Wang Yaping face, and how will the space teaching be carried out?
1. Problems in diet, hygiene, bathing, etc. in space life.
Space life refers to a state in which astronauts live and work in space, and the harsh space environment also brings great challenges to the life of astronauts, so they will be equipped with space living facilities.
This time, the launch of Shenzhou-13 will have three astronauts living in space for a long time, so these living facilities will become very important.
In space life, people's lives are very different from those on Earth, from the preparation of diet, hygiene, to the way of bathing.
The first is diet, space food refers to food that is consumed in the space environment, transported from Earth into a capsule, or produced in a space capsule.
But space food also has its own characteristics, one is the life and preservation of food, because in the space environment, the fungus of food will multiply very quickly, so the preservation of food needs to be very strict.
Second, the preparation and intake of food will be different due to the reason for weightlessness, and food in a weightless environment will have a very large impact on the cooking and taste of food.
In addition, there is also the handling of food, in the space environment, the excretion and defecation of astronauts need to go through special treatment and disposal to ensure that the normal operation of the spacecraft will not be affected.
The processing of urine and urine excretion is mainly done through the space toilet, which is usually carefully designed, because there is no gravity in the space environment, so the excretion of urine and urine will float, which will affect the normal operation of the spacecraft in serious cases.
Therefore, the space toilet is usually equipped with suction to prevent the excretion of urine and urine from floating to other places and affecting the spacecraft, and after the excrement is inhaled, the feces will be dried and finally incinerated into water vapor and discharged, and the urine will be separated from the water, and the separated water will be sterilized and then ready for drinking.
The second is bathing, and there is no water in the space environment, so the way of bathing will be very different, and due to weightlessness, the water is uncontrollable, so the way of bathing will also be very special.
The way to take a bath is usually to use wet wipes for local cleaning, while the way to wash hair is to do it by dry cleaning, because dry cleaning consumes less water and is easier to control.
There is also the problem of food residues, which also cannot be discarded in space, so they are absorbed and separated, and finally incinerated into water vapor and emitted.
But flying in space, not only these problems, but also many special problems, make life in space more challenging.
2. Long-term flight in the space environment will have an impact on the body.
Flying in the space environment for a long time, whether it is the space environment itself, or other factors, can have an impact on the astronaut's body.
The first is weightlessness, which means that in the space environment, the astronaut's weight will become very light, or even zero, which will have an impact on the astronaut's bones and is prone to osteoporosis.
In addition, weightlessness can also affect other organs of the body, such as heart disease and high blood pressure, so astronauts usually exercise to maintain their health when flying in the space environment.
In the space environment, there are other problems, such as radiation, which will affect the body of astronauts, so the physiological problems in space life are becoming more and more important.
Especially with the deepening of space exploration, there will be more astronauts flying in the space environment, which also requires scientific researchers to continuously innovate and improve space living facilities and technologies.
Therefore, the R&D and production technology of space food will attract more and more attention, and how to ensure the taste, nutrition and safety of food is a challenge.
In addition, the design and improvement of space toilets and bathing equipment have an important impact on the quality of life and work efficiency of astronauts.
Therefore, researchers need to continuously conduct research and improvement to provide better facilities and technologies for space life.
3. The evolution and water consumption of space bathing.
Space bathing is relatively simple compared to space toilets, but space bathing also has its own peculiarities.
There are two main ways to take a bath in space, one is by dry cleaning and the other is by local cleaning with wet wipes.
Dry cleaning is relatively simple and water-saving, so in the space environment, bathing is usually carried out by dry cleaning, and wet wipes are mainly used for local cleaning, such as washing face, washing hands, etc.
From the way astronauts take a bath when they first enter space to the way they take a bath now, it is constantly changing.
The space capsule of Shenzhou 13, in which Wang Yaping is riding, also has its own bathing equipment, which provides convenience for astronauts to take a bath.
In the space capsule of Shenzhou 13, the bathing equipment is mainly wet wipes and dry cleaning equipment, and in the dry cleaning equipment, there are special body cleaning wipes, which can clean the astronauts' whole body, and the water consumption is about 5-8 ml.
In addition, astronauts can also use wet wipes for local cleaning, such as cleaning the face, cleaning hands, etc., and the water consumption of wet wipes is about 1-2 ml.
However, it is impossible to control the water when flying in space, so when taking a bath, you need to be especially careful so that the water does not fly away to other places and affect the normal operation of the spacecraft.
epilogue
With the deepening of space exploration, the physiological problems and solutions in space life are becoming more and more important, so researchers will continue to conduct research and improvement to provide better space living facilities and technologies.
But for female astronauts, the physiological problems of life in space will be a little different, and these problems may require more attention and research to provide more suitable solutions.
