Three astronauts don't have to work night shift in the space station

On June 20, according to media reports, in order to ensure the safety of the platform, astronauts used to take turns on "night shift" in space. In the Shenzhou 12 mission, the three astronauts do not have to work on the night shift. The new acousto-optic alarm system can inform the astronauts in time to deal with the situation quickly. They can have a good sleep, have enough energy, and continue to work when they wake up!

Netizen: really good!

At 9:22 a.m. on June 17, shenzhou-12 manned spacecraft ignited and lifted off at Jiuquan Satellite Launch Center. After the spacecraft entered orbit, it successfully completed the orbit entry status setting. At 15:54, the spacecraft successfully docked with the forward port of Tianhe core module in the autonomous rapid rendezvous and docking mode, forming a three cabin (ship) combination with the previously docked tianzhou-2 cargo spacecraft. The whole rendezvous and docking process took about 6.5 hours. At 18:48 p.m., three astronauts successively entered the space and core module from the Shenzhou 12 manned spacecraft. Nie Haisheng, Liu Boming and Tang Hongbo will begin their three-month space life. This is also the first time that China's own space station has welcomed "resident residents". So how do astronauts spend three months in space? In the "space mansion", how do they have their own "personal space"?

What did the astronauts bring into space?

There are family videos and sleep aids

Wu Ji, chairman of the Chinese society of Space Sciences and researcher of the National Center for space science of the Chinese Academy of Sciences, told Chengdu Business Daily - Red Star news that because the astronauts have lived in space for a long time this time, and with the arrival of the cargo spacecraft, there is still space in the spacecraft to allow them to carry personal belongings, and the astronauts can also carry belongings related to their hobbies.

The three astronauts also revealed their personal belongings in an exclusive interview with CCTV news. Astronaut Tang Hongbo revealed that he was going to take the secretly recorded video of his son's life to the spaceship. Tang Hongbo said: "my son is very humorous and optimistic. It's also a relaxation of ordinary life to take a look at these videos of living with relatives Astronaut Liu Boming took a family photo, a "cow Doll" and a small bag of sleep aids. He revealed that some of these items were in the core module, some in the cargo module, and some went into space with the shenzhou-12 manned spacecraft. And astronaut Nie Haisheng left a suspense, he said he would bring the items in space to show you.

How do astronauts eat?

"Space kitchen" can make fish flavored shredded pork and kung pao chicken,

You can also make western food

In space, whether astronauts can eat well and enjoy delicious home food is very important for the three-month space life of shenzhou-12.

Tang Hui, deputy director designer of aerospace Sanjiang Hongfeng company of China Aerospace Science and industry group, said in the interview that the food heating device in the "space kitchen" is installed in the spacecraft, which can heat the astronauts' space food and beverage quantitatively, and the heating temperature and heating time are controllable.

This food heating device is a white square box with three layers of heating space. Just press the power switch gently and wait patiently for a while. Astronauts can enjoy warm food in space.

Tang Hui said that the rice, fish flavored shredded meat and Kung Pao diced chicken from here can make astronauts in space enjoy the taste of "home". Of course, if you want to change your taste and have a western meal, "space kitchen" is also handy. If astronauts choose to heat manually, they can choose the heating time by themselves.

According to the design, the locking device of the "space kitchen" - food heater adopts a mechanical device, and the astronauts can lift the "pot cover" easily after loading the food they want to eat. This device has strong shock resistance and impact resistance, which can ensure that astronauts can eat hot food steadily in the spacecraft.

What should astronauts do when they are homesick?

When WiFi is installed, you can make video calls with your family

On June 16, at the press conference of Shenzhou 12 manned mission, Ji Qiming, assistant director of China's manned space engineering office, introduced that astronauts can realize two-way video calls and send and receive e-mails between the space station and the ground through space communication links and video communication equipment.

Wu Ji explained that because China now has three geostationary satellites, the space station can first transmit information to the 36000 km high geostationary satellite, and then the geostationary satellite sends it back to the ground measurement and control center, realizing real-time transmission of information.

According to the microblog of people's daily, Sun Jun, chief mission engineer of the space station of Beijing space flight control center, said that the wireless WiFi device has been taken to space and installed by the astronaut crew on the morning of 18. With WiFi, astronauts can have smooth communication and video calls with ground personnel and even their families.

So every move of an astronaut needs to be monitored? Wu Ji said that the astronauts have their own private space, and each astronaut has a small rest room. They have private activity space. In this regard, Yang Yuguang, vice chairman of the Space Transportation Committee of IAF and researcher of the second Academy of China Aerospace Science and industry group, also explained: "astronauts have private space. When they talk with their families, they are all in private space and can not be heard."

Do astronauts have recreational activities in space? Wu Ji said that besides working hours, astronauts also have their own rest time, which can arrange their own lives, such as watching movies or doing other things in their notebooks.

So, why do astronauts need to perform synchronous work and rest? "Because ground controllers and astronauts need to rest," Wu said. In addition to some experiments that need to be done day and night, most of the time they work and rest according to the normal schedule, and the ground measurement and control service support personnel can also work and rest according to the normal schedule. We have a normal work and rest, which is more conducive to staying in the space station for a long time in the future. It is also good for the health of astronauts to keep the same work and rest as on the ground. "
