Video is going viral on social media

Digital Desk, Beijing. These days a video is becoming fiercely viral on China’s social media. In this video three Chinese astronauts are having a lot of fun in space. In fact, long duration flight in space is tiring for astronauts, and it is not less than a big challenge, so entertainment is also very important it happens.

In this viral video, Chinese astronauts can be seen listening to music, watching movies, exercising, and even getting their hair cut in space. Commander Chei Chikang has put on a new hairstyle, and his co-astronaut Yei Kwangfu has helped cut his hair. Indeed, cutting hair in space far from Earth is no easy feat.

Well, a safe and reliable water supply is also a must for Chinese astronauts who have been in space for quite a long time. Water is made available to astronauts in three ways: transportation by spacecraft, on-site production, and water-recycling. Water is also generated in the space station via a fuel cell combining hydrogen and oxygen. This reaction also generates energy that is converted into electricity to power the space station.

The cooling of this reaction produces water, and its temperature is brought down to 18 to 24 °C and purified by a silver ion sterilizer before being sent to the storage tank. At present, the Chinese astronauts have three months A lot of water is drunk during the stay. Water-recycling and reuse can help meet water demand. Not only this, the urine produced by Chinese astronauts is also collected and treated to extract pure water.

Human physical activity data shows that each astronaut generates approximately two kilograms of urine and flushing water per day in the space station. During the same period they release about 1.8 kg of water vapor into the cabin. Then, treating it in pure water can provide an essential source of drinking water in space.
