Astronauts are not allowed to fart on the space station, and what is the reason for this regulation?
We can "fart" anytime and anywhere on the ground, so why not in space?
Is there any scientific basis for this provision?
Astronauts must not fart in the space station, so how terrible are these farts?
1. It is normal for the human body to fart.
One of the normal physiological phenomena of the human body is farting, everyone has to have different degrees of defecation and farting every day, in which the number of farts varies from person to person, but in general, the normal number of farts per person per day is between 10 and 15 times.
Among them, the main components of fart gas are nitrogen, carbon dioxide, hydrogen and methane, among which nitrogen and carbon dioxide are excreted by the human body through breathing, while hydrogen and methane are produced from the gas excreted from the digestive tract.
At the same time, hydrogen is a flammable gas, on the ground, we smell from the composition of the fart from time to time, but due to the high oxygen content in the air, it is not dangerous, but in space, due to the extremely low oxygen content, once there is a spark, it is extremely easy to cause a fire or explosion.
At the same time, methane is a greenhouse gas, which will also have a certain impact on the air environment of the space station, which is not tolerated in the space station, so astronauts must be strictly prohibited from farting.
Scientists are not completely unprepared for astronauts' farts, but have studied the problem of astronauts' farting in space and provided some solutions to it.
2. Dietary adjustment of astronauts.
In space missions, astronauts exercise far less than on the ground, so they don't need to take in a lot of calories like on the ground, plus in the space environment, a lot of exercise is not so easy to sweat, so for astronauts, more excrement is still fart.
Therefore, scientists have developed a set of plans for astronauts in space to reduce the production of excrement, that is, a dietary adjustment program, on the one hand, to reduce the production of excrement, on the other hand, it is also hoped that astronauts can eat nutritious and delicious in space to improve the comfort of astronauts.
The first is to reduce the production of gas in the intestines, so scientists first adjusted the astronauts' diets to reduce gas-producing foods as much as possible from food, such as beans, cabbage and other vegetables, these foods will produce a lot of gas during digestion, so in space missions, it must be avoided as much as possible.
Secondly, it is the precautions when eating, astronauts must chew food slowly when eating, avoid swallowing air when swallowing food, in addition, when drinking water, also drink a little less, drink slowly, avoid drinking bubbles, can effectively reduce the production of body gas.
In addition, scientists have also specially designed a device for astronauts to fart, which can collect the fart gas released by astronauts, remove the harmful gases through filtration and purification, purify the air, and then re-discharge it, which can not only effectively reduce the impact of fart gas on the work in the space station, but also ensure the cleanliness of the air environment of the space station.
3. The challenges of astronauts in space.
Although the mission of astronauts in space is much easier than that on the ground, there are still many challenges and tests for astronauts in space.
First of all, it is the microgravity environment, we have seen a lot of videos about astronauts in space, we can find that due to the microgravity environment, the astronauts walk in space in a weird posture, and it is particularly troublesome to do things.
Because there is no limit of gravity, objects in space will no longer be like the ground, as long as they are placed there, they will not move, but will float anytime and anywhere, in such an environment, it is very inconvenient to do things.
In addition, without the alternation of day and night in space, the biological clock of astronauts will become chaotic, and over time, it may become a state of not waking up every day, which will seriously affect the work and life of astronauts.
Astronauts carry out space missions, which may last for several months, or even more than a year, and during this period, they may lose contact with family and friends on the ground, and become lonely and helpless.
Therefore, in order to better cope with these challenges, astronauts need to undergo a series of training, not only to be familiar with space technology, but also to have a certain adaptability to life and work in the space environment.
At the same time, it is also very important for the rehabilitation after completing the mission, scientists have specially designed a set of special rehabilitation programs for these "astronauts" in space, through which the astronauts can quickly recover from the space environment and return to the normal life trajectory on the ground.
epilogue
The regulations on the control of fart gas in the space station, from one side, are the importance of overall safety, and also remind people to pay attention to environmental safety in daily life, control fart and harmful gas production, and pay attention to a healthy diet to reduce the production of fart gas.
The challenges faced by astronauts in space missions are not only technical, but also many physical and psychological difficulties, and the ability to stick to the space station and complete the mission is a reflection of the professionalism and resilience of astronauts.
