On April 12, 1961, the Soviet astronaut Gagarin was launched on the Vostok 1 spacecraft, out of the earth for the first time, becoming the first astronaut to out of the earth in the history of mankind. Gagarin’s success has opened a new step for mankind to explore the universe.
In the following half a century, astronauts will enter space to perform missions and work every year. Astronauts enter space to stay in a spacecraft or a space station. If they are in a space station, they will need to stay longer. Whether it is a short stay in space or a long time work, astronauts cannot do without daily life.
Metabolism is the core of life. Human beings are naturally not gods. They need to eat and drink Lazard anywhere. This is a basic physiological requirement. The waste produced by eating and drinking needs to be excreted from the body through metabolism, otherwise it will cause harm to the body. Lazard is a very simple thing on the earth, and only a normal and healthy person can easily solve it.
So what is the daily life of astronauts in space? Is it as simple and easy as on earth? I believe many friends know that as a respected and noble profession, astronauts are not suitable for everyone. In addition to having strong physical fitness, they also need to have good psychological quality.
After we are selected as astronauts, we need to conduct various trainings before entering space. One of the trainings is very important, that is, going to the toilet. Many people may say that toileting is a basic human technology, and this still needs training? If you think that going to the toilet in space is a simple and easy thing, you are wrong.
In fact, going to the toilet in space is something that astronauts are very reluctant to do, but because of physiological needs, there is no way. And every time to go to the toilet is a test for astronauts. If it is not done properly, it will bring a series of troubles, and may also bring danger to the health of astronauts.
Maybe some friends don’t know this well, so let’s make some brief introductions. I believe my friends all know that the water in the toilet on the earth flows downwards. It is very simple to go to the toilet. This is because the earth has gravity. Under the action of gravity, all objects will have a downward force. Naturally Don’t worry about the upward discharge of urine and feces.
However, the space environment is close to a vacuum. The manned spacecraft is in a microgravity environment. In the natural state, water does not flow downwards, but upwards. In this environment, it is naturally impossible for us to use the common toilet on the earth, otherwise it will be a disaster.
So what kind of toilet is used in a manned spacecraft in space? It is a kind of airless toilet similar to the principle of a vacuum cleaner. The price is very expensive, reaching tens of millions of dollars. The air-breathing toilet relies on airflow to take away the urine and feces, encapsulated in a sealed plastic bag, for disposal and storage.
Some people may say that an air-sucking toilet can solve the problem of water flowing up in space, so astronauts should not have much difficulty in going to the toilet, but this is not the case. The air-sucking bucket only solves the problem of water flowing up, but Astronauts want to complete this toileting process, but they need some precise operations. For example, when using the toilet, the buttocks must be close to the edge of the toilet, and no gaps should be left, so that the toilet is completely sealed status.
Only if the toilet is kept in a sealed environment and completely isolated from the outside world, can the toilet be effectively prevented from flying out of the toilet. If the sealed state is not done properly, the urine and urine will float out of the toilet and fly around in the cabin, as if “The goddess scattered flowers” became a disaster.
If you think that you can successfully go to the toilet just by sealing the butt to the edge of the toilet, then you think it is too simple. This operation is only the first step, and there is one more step that needs to be completed before you can go to the toilet successfully. The central hole in the quasi-toilet cannot be deviated. This operation has a certain degree of difficulty and requires astronauts to undergo special training.
It can be seen that it is indeed not an easy task for astronauts to go to the toilet in the spacecraft. Without special training, they will basically fail. The result of failure is that the cabin becomes a mess. You can imagine that kind of scene. How embarrassing. The toilet in the early spacecraft was not advanced. Every time an astronaut went to the toilet was like fighting a battle, he needed to be careful and careful. Even so, there were times when he failed.
However, with the continuous development of human aerospace technology, the spacecraft toilets are now considered to be relatively advanced. Basically, as long as they are trained, astronauts can successfully go to the toilet and their safety has improved a lot. Of course, the more advanced space toilets are, the more expensive they are, basically tens of millions of dollars. No wonder manned spaceflight is so expensive that only major countries can afford it.
Of course, even the most advanced space toilets are not as convenient and safe to use as simple toilets on earth. The reason is simple, that is, the microgravity environment. As long as this microgravity environment cannot be solved, then human life in space will not be as comfortable as on earth. I believe that friends have watched many science fiction movies. In the spaceships in the movies, people can walk and live freely. It’s like being on the earth.
The reason for this is that the spacecraft has artificial gravity, which can simulate an artificial environment, allowing people to enjoy the same gravity in space as on the earth. With this artificial gravity, the daily life of astronauts will become simple and relaxed, unlike ours now, who have to be careful when going to the toilet.
Of course, the artificial gravity in science fiction movies is still a futuristic technology for the current human technology, and it cannot be achieved in a short time. Spaceships without artificial gravity are destined to restrict humans from reaching farther starry sky. Humans want to carry out interstellar voyages in space and survive in a microgravity environment for a long time, which will cause major damage to our bodies.
Therefore, artificial gravity is a key technology for mankind to enter the starry sky in the future. Without it, even if we have the speed to get out of the solar system, we can only go out with unmanned probes, and manned cannot be carried out. I believe that with the current development speed of human aerospace technology, artificial gravity can be realized in a few years, and that is when humanity officially starts interstellar exploration.
