Since the Shenzhou 14 astronauts entered the Tianhe core module on June 5, they have worked and lived in orbit for more than 20 days, and have successively completed the transfer and arrangement of materials, the establishment of the residence environment, and the installation and commissioning of equipment in the cabin.
At present, the astronauts are in good condition.
After the Shenzhou 14 astronaut crew entered the core module, they quickly adapted to the space home in the microgravity environment.
According to estimates, each astronaut needs to drink 2 kg of water per day. In addition to the regular upward water, the space station can ensure the daily drinking water demand of the astronauts through the recycling of water resources.
This is astronauts Chen Dong and Cai Xuzhe setting up a drinking water dispenser, which allows the astronauts to drink warm water at 45°C.
Since the water stored in the space station is not mobile, astronauts also need to complete the detection of microorganisms in water samples regularly to ensure the safety of astronauts' drinking water in orbit.
Through the lens, we can see that Chen Dong instructed Liu Yang to conduct water sample testing according to the instructions, complete microbial sampling and culture medium filtration, and every step was very rigorous.
