Liu Yang The animation of working with the "explosion head" in the Tiangong Space Station was once again attracted by everyone. Judging from the surveillance cameras in the space, Liu Yang, who was working with the "explosion head" and selflessly did not care. This made everyone unexpected that the gentle and delicate Liu Yang actually had such an ungrateful side...
Liu Yang's " explosion head " is really helpless?
On June 6, Liu Yang swiped the photos of his mobile phone in space station , which made everyone discover a "very serious" problem for the first time. Liu Yang, who had short hair with ears, turned into an "explosive head". Such short hair turns into a "explosive head". If you tie it up, you will become a "explosive head" under weightless conditions. If you don't tie it, you will have your own ideas and float with the airflow and turn it into an explosion head.
At that time, many friends came up with ideas, such as wetting their hair. Of course, this is a bad idea. The humidity conditions in the space station are required, so you cannot increase the humidity at will. What is more reliable is that someone recommends using shower cap . This idea is good, because there are shower caps in the space station, so the author is also wondering if he will wear a shower cap next time he sees Liu Yang?
Obviously, the surveillance screen continued to be released on June 8 made everyone see the "explosive head" again. Liu Yang was focused on his work, not caring about the fact that his hair was put on his head and had let himself go. This surprised everyone. Liu Yang, who is usually gentle and charming, is so ungrateful, but everyone understands it. After all, on the Tiangong Space Station, work is the first priority, and his image is the best. If you can pay attention, try to pay attention.
Liu Yang's long hair in space
It is estimated that in a few months, Liu Yang's short hair with ears should gradually develop long shawl hair. Everyone will guess whether Liu Yang will cut it into short hair again. The flower planter's bet will not. He will follow the trend and develop long shawl hair, and then tie it with a hair rope. It looks more energetic and the cost is also very low.
Space Station 6 months: The most difficult thing is to wash your hair, take a bath and go to the toilet
Tiangong Space Station orbits the earth at a speed of more than 7.7 kilometers per second. The " centrifugal force " it generates "counterattached" with gravity, so the space station is weightless. It is particularly inconvenient to do many things in this state, such as eating. In the past, they used to squeeze toothpaste and become disgusted.
Currently, the space meals are relatively rich, but they all have two characteristics. Most of the main meals are sticky, because this is not easy to separate and float out when disturbed. Desserts and snacks are all in one bite, and there will be no situation where debris fly everywhere because under weightless conditions, these debris will float everywhere, which will often block the ventilation air inlet or the heat-dissipating air inlet. If it is water droplets, it will be even more troublesome.
Eating and drinking on the space station are actually very familiar with it. There is no need to plant flowers and have to waste more time. This article mainly introduces two things to you: one is how to bathe in space, and the other is how to urinate and defecate. These two common events have a dark history in space.
bathing: There was once a super luxurious heated shower room
bathing in the space station may be the most luxurious thing. If the shower on the earth consumes at least 30L of water at a time, if it is a bath, it starts from 100L directly. Do you know the value of each liter of water in space? The shipping fee is $10,000 per kilogram, even if it is, 100L costs about $1 million.
But fortunately, it can be recycled. Currently, the recycling rate of space water in is extremely high. Even the water in the urine can be reprocessed into drinking water. Therefore, taking a bath is still acceptable, but bathing in space is a super troublesome thing.
Because of weight loss, the shower and tub bath you imagine will not appear. In the early days, it was mainly used to wipe the body. However, a device for bathing astronauts appeared in the Sky Laboratory Space Station in the United States. This is a folding shower barrel. When taking a shower, the airflow passes from the top of the head to the feet to prevent the suspended water droplets from being sucked into the lungs by the astronauts. There is a 2.7L water tank outside the large round barrel. It takes 45 minutes to heat it in a bath.
However, the astronaut's bathing experience is not good, because the heating power is insufficient, the water will become colder and colder, and it is easy to malfunction. It takes 2 hours to take a bath at a time, and after a few times, the astronauts put it aside.
The bathing method of the former Soviet Union's space station is somewhat similar to a sauna, with heating air flow passing through the bathtub, but when using it, you have to wear goggles and a respirator to prevent water droplets from entering the eyes and lungs. However, the malfunction is similar to that of the equipment in the United States. It takes a long time to heat it and it is troublesome to take a bath. It takes 2 hours to disinfect the machine, so the result is the same, and it is supplied after it is used once.
How to take a bath on the International Space Station?
American astronaut Clayton C. Anderson has an answer in Quora, sharing his bathing process on the space station. He once worked on the International Space Station for 152 days. He told everyone that there is an area dedicated to personal living in the Russian FGB (Functional Cargo Block) module, which they call it a health station.
There is a water bag on the top of this small area, connected with a hose and small water pump , and there is a water dragon at the end of the water pipe. In this area, they can brush their teeth, shave, wash their hair and bathe, but they must be cleaned after personal use.
brushing teeth: brushing teeth is very simple, just don’t open your mouth to avoid foam flying outside and run around. Then the toothpaste foam after brushing can be spit into a towel, but Anderson often swallows these things and will have a good mint smell. This toothpaste is not healthy for those who swallow it, but the flower grower thinks this behavior is disgusting;
Shaving: Spray some water on the face, then apply it with shaving cream and deal with it directly. Shaving is relatively simple, but it cannot be rinsed, so you can only wipe it with a gauze pad;
shampoo: Use non-rinsing shampoo to moisten your hair, and then grab the hair to soak the scalp. Although it is non-rinsing, Clayton C. Anderson still "rinse" with water and then use a towel to suck the water dry;
bath: According to Anderson said that he still uses a similar method to wash his hair, which is to wipe the body with water-free bath solution. However, this is the standard process. Anderson still likes to use water to wet the towel and wipe the body.
According to some information, there are fully automatic bathing equipment on the International Space Station and can also bathe according to the set procedures. It seems that this statement is not credible. After all, it is easy to cause failure. It is not cost-effective to build a set of equipment, so it is better to wash the bath.
How to take a bath on Tiangong Space Station?
According to public information, Tiangong Space Station can only wash baths, after all, the space is still relatively limited. However, Shangguan News reported on on June 22, 2021 that the bathing method of Tiangong Space Station is slightly different, and it is sprayed in a wrapped shower bag in . Then finish the full bath in the bag, this method seems to combine some advantages.
's dark history of going to the toilet: You can't believe that it is actually like this
used to have no toilet at all, only a bag for urine and feces, and when operating... I won't talk about it. You can figure out the operation scene by seeing these two things.
The picture above is a urine bag for a male astronaut to put on urine, so there is no need to explain how to operate it.
This is a plastic bag for stool, and there are operational instructions. I guess you will know it at a glance, and you will be useless as soon as you learn it! Because if you have diarrhea or too dry, this experience will be extremely bad.
The bottom right of the picture above is women's supplies. There is no need to say much. I believe you can understand how to use it!
But it is obviously not a good idea to install it like this. For example, during Apollo 10 , someone did not put it in his pocket, and a piece of shit ran out. He was so scared that he ordered the boss Eugene Cernan to find a piece of paper and wrap it up to deal with it. This matter is still a unsolved case. I don’t know who the owner of this piece of shit is.
Space toilet has been developing for more than half a century. At the earliest, there was a toilet on the Soyuz in 1967, but it was very inconvenient to use. There was a WCS system in the Sky Laboratory from May 1973 to March 1974, which was used to collect urine, feces and vomit, etc. that returned to the earth.
The toilet device on the Soyuz spacecraft
WCS has developed to now be the UWMS (General Waste Treatment System) on the International Space Station. This is the first specially designed space toilet, which simplifies the use of women's space toilets and the use of feces and urine at the same time. It is designed to deodorize, fully automatic, quieter, lighter, more reliable, sanitary and more compact than previous systems. It is no longer a collection system, but a comprehensive waste treatment system.
UWMS (General Waste Treatment System) on the International Space Station
Although it has changed from collection to comprehensive processing, the astronaut release and collection process is not much different. It is just that man-machine engineering is better, but the operation is still relatively difficult and the experience is still not good enough. The main reason is that these excrements are not obedient in weightless states and need to be collected with negative pressure, so they need to be aligned at the hole, which is really troublesome.
What about the toilet on Tiangong Space Station?
actually had a toilet since Shenzhou 5 , but the toilet at that time was a collection system, and it was also in orbital cabin . Therefore, because he was cautious when Yang Liwei went to the sky, he did not let him take off his space suit in the cabin. Therefore, he really never used the toilet in the orbital cabin of Shenzhou 5:
When
, these collection equipment were installed in the orbital cabin, and I was alone in the first flight, so I couldn't share the orbital cabin, so I didn't use these equipment.
Since I am the first person to fly in China, I am not required to take off the space suit , and I need to wear it even if I urinate.
This is Yang Liwei's original words, so Yang Liwei was wearing diapers back then, and he was likely to have a lot of shit (it was a secret whether it was there. After all, the task was 21 hours, and the preparation time was more than 24 hours, but some people were constipated and it was okay not to shit for a day). Of course, this is also impossible. Safety first, and the others mainly focus on completing tasks, so the order must be followed.
After Shenzhou VI , there will be no so many rules. Astronauts can at least go to the toilet. The main principle of the collection system is negative pressure collection, which is much better than the plastic bags in the Apollo era and can be regarded as toilets.
However, in the era of space stations, this is not a toilet, but a waste treatment system, including deodorizing, water supply, and easy-to-disinfect collection system, which has reached the system level. However, the use requirements of toilets are still very high. This has nothing to do with the design and the environment. The moisture in these excrements will still be collected, processed, recycled and utilized.
It is estimated that many friends will feel very disgusted about this, but in fact, the Tiangong Space Station has processed " regenerated water ", which is cleaner than mountain spring water. If you look at the processing process in the picture above, you will understand that it will undergo an electrolysis process, convert it into hydrogen and oxygen and then generate water through chemical reactions, which is cleaner than the purification process of nature.
