Now, the construction of the Chinese space station has achieved the victory of the first stage, the Tianhe core module has passed two batches of astronaut residency verification, one is the Shenzhou 12 astronauts stayed for 3 months, the other is the Shenzhou 13 astronauts stayed for 6 months, the facts have proved that the quality of the Tianhe core module is reliable, and long-term residence is no problem.
The construction of the second phase of the Chinese space station is being carried out in an orderly manner, the Tianzhou-4 cargo spacecraft and rocket are undergoing final assembly and testing, the materials to be transported by the Tianzhou-4 spacecraft have long been prepared, the Shenzhou 14 manned spacecraft has also been built, and the Shenzhou 14 astronauts and Shenzhou 15 astronauts have been selected.
We on the earth for a long time, we have a strong interest in the alternative way of life of astronauts, space station astronauts eat and drink, how to sleep, how to wash their hair and bathe, how to work and study, bored, with the exposure of a large number of astronaut life videos, we slowly found the answer.
But there are still some strange questions about astronauts, some people are still looking for answers, the most interesting question is, the Chinese space station does not have a space washing machine, what if the astronauts wear dirty clothes?
Washing clothes on the space station is a luxury within luxury
On the earth, we wear dirty clothes to the washing machine inside a throw, put in some special chemical laundry detergent, press the washing machine button, the washing machine will automatically complete the whole process of washing, some even include drying, washing clothes without water can not do, washing clothes once need to consume hundreds of kilograms of water.
Residents use less than 6 yuan a cubic meter of water, hundreds of kilograms of water for us, really nothing, but for the space station astronauts, this is definitely a luxury in luxury, to know that with the help of the space station's life support system, the total water consumption of 3 astronauts staying for 6 months does not exceed 2 tons, including domestic water.
On the space station, astronaut bathing is a luxury event, there are hundreds of astronauts in the world, but only the American female astronaut Weitz has enjoyed a "space shower", it is estimated that she will remember a lifetime, before and after the bath took 1 hour, shower 15 minutes, vacuum cleaner sewage water took 45 minutes.
In order to clean the body, whether it is an international space station astronaut or an astronaut on the Chinese space station, the practice is the same, using special wipes to wipe the body, but before use for heating, the International Space Station astronauts have revealed: use a wet wipe every two days, before use for heating.
This is because the water in space is too precious, this is not the value of the water itself is very high, but the cost of transporting water is very high, there are data show that the cost of transporting 1 kilogram of rocket launch is about 10,000 US dollars, if the astronauts take a shower, a bath can make a rich man instantly bankrupt.
The space station has a water recycling system, even astronaut urine can be filtered into drinking water, bath water is always much cleaner than urine, the bath water can be recycled, in fact, this is not feasible, bath water contains compounds, water circulation system can not filter these compounds.
In the same way, the washing powder and laundry detergent we add when washing clothes are also compounds, and the water circulation system cannot filter these compounds, so it is unrealistic to wash clothes in space, unless, scientists invent a space washing machine that hardly requires water, astronauts will go to wash clothes, and there is currently no washing machine in space.
What should I do if the astronaut's clothes are dirty?
There is no washing machine on the space station, so what if the astronauts wear dirty clothes? In fact, wear dirty do not have to wash, directly throw away is good, there is nothing reluctant, our Tianzhou cargo spacecraft transport materials include a large number of clothes, enough for 3 astronauts up to 6 months of space station station consumption.
The space station is clean and tidy, there is almost no dust, so the astronaut's clothes are not so easy to dirty, you can wear it for several days at a time, of course, underwear underwear, socks must be changed frequently, but underwear underwear, socks are relatively small clothing, itself does not have much weight.
At last
Got it? Astronauts wear dirty clothes to deal with the way to throw away, change new clothes, this is no pity, relative to reuse, this is already the most cost-saving approach, but this does not mean that it will be done in the future, it is said that the United States is studying space washing machines, to see space washing clothes is not impossible.
