The life of astronauts in space is relatively limited. If you want to drink healthy water, you must provide healthy water. It is found that the storage space of the space station is very small. If you want to send some materials into space by cargo ship, the cost is very expensive each time. It takes 630 thousand per person to transport water alone. In addition to taking some water with the space station, there are some ways to solve the water problem, which can be reused through wastewater treatment. Therefore, condensed water will be collected and purified in the astronaut cabin as one of the important drinking water sources.
It is refreshing for people to drink water on the earth, but it is not particularly smooth to drink water in space. Drinking water requires some specific skills, because space is a microgravity environment, everything will float, and water will also float in the air. Astronauts need some skills to drink water. If the water floats when drinking water, it may block the astronauts' nostrils, which will become more serious at this time. It can be found that when astronauts drink water, they usually put some clean water into soft water bags in advance and drink the water into their stomachs by sucking.
Drinking water is necessary, and bathing also needs water. The action in space looks much easier than on the ground, but it is easier to sweat in space, so astronauts need to take a bath after staying in the air for 6 hours. If you don't take a bath, the bacteria on your skin will grow quickly, and it is also important to clean your skin. At this time, a lot of water will be used. Therefore, astronauts usually use wet towels to wipe when taking a bath in space. Generally, this kind of towel contains a large amount of water.
