This space flight mission is long and heavy, in order to let The astronauts are fully rested, and my country’s space station implements a system of synchronized work and rest between the world and the earth. In other words, the working hours of the astronauts on the ground and on the space station are the same, 8 hours a day, one day off a week, and no night shift is required.

Every day at 6 o’clock in the morning, the astronauts get up to wash and prepare breakfast, start to eat at 7:30, and the ground flight control staff arrive at work at 8 o’clock. The astronauts begin to communicate with the ground about the mission plan and start the day. Intense work.

After 12 noon, it’s lunch time and noon break. Around 20 pm is the second report. The main task is to report to the ground the completion of the day’s work and suggestions for the adjustment of the work plan for the next day. .

Because there is a new type of sound and light alarm system in the space station, it will alarm in time when there is an abnormal situation, so the astronauts do not need to take turns “night shift” every night, and can sleep peacefully and replenish their energy.

But many times I have to work overtime. Before each exit, the astronauts should start preparations 5-6 hours in advance, wear an extravehicular space suit, train on orbit, inhale oxygen and discharge nitrogen, pass the gate and open the door, and then continue for 6-7 hours. Work hard.

There is a degree of relaxation and a combination of work and rest. Normal work and rest is an important guarantee for the astronauts to continue their stable work on the space station.

Every Sunday and 1 hour before going to bed are the astronauts’ free time. On weekends, they will collectively clean the space station. In other free time, they can listen to music, play games, watch videos, watch live TV in real time, and talk to family, friends, and colleagues on the phone.

The live broadcast, they are serious

Look, the “firework gas” on the Chinese space station

1.4 billion Chinese people, of which 100 million are broadcasting live broadcasts, but there are only a handful of big coffees who can open space station live broadcasts. People are curious about all aspects of the space station, and live broadcasting has become an important way to showcase life in space and publicize space careers.

In the “first lesson of school”, the “space travel trio” showed a good sense of life on the space station. Liu Boming took the students to roam the space station, showing the space kitchen, hot air device, microwave heating device, three meals a day, drinking water system, refrigerator and other facilities. Nie Haisheng led the “Space Sports Class”, and three astronauts led the children to play “Sky Survey Tai Chi”. Tang Hongbo prepared two scientific experiments, “drinking tea with chopsticks” and “planting space sweet potatoes”.

On September 3, the China Space Station System Construction Symposium was jointly held in Beijing and Hong Kong. During the symposium, astronauts and nearly 300 Hong Kong science and technology workers, teachers and students had a dialogue and live show Space station life. The astronauts answered various questions raised by young people in Hong Kong, demonstrated in detail the functional divisions and daily operation procedures of the space station, and introduced methods for exercising in space.

The “Eat and Broadcast in Space” is especially impressive. In the video, Nie Haisheng and Liu Boming began to prepare breakfast at around 7 in the morning, fixing the meal package on the table, and more than 120 aerospace “signature dishes” (fish-flavored pork, kung pao chicken, black pepper beef tenderloin, spicy Lamb, hot and spicy goose, hot and sour bamboo shoots, spicy tofu, etc.) aroused everyone’s admiration and envy.

Wi-Fi coverage, smart home

Since the astronauts entered the space station on June 17, early the next morning, they first assembled the Wi-Fi equipment. Just as Wi-Fi has become an indispensable part of family life, with the support of wireless communication and Internet of Things technology, the space station also has “mobile Wi-Fi”, creating a smart home living space and becoming the most intimate basic service.

In addition, the space station has reserved a private voice channel so that astronauts can chat with their families at will and share their feelings of living in space.

Usually, the astronauts wear bone conduction headsets, connect to the Bluetooth of their mobile phones, and then connect to the equipment in the cabin via Wi-Fi, so they can talk to each other at various locations on the space station and communicate with the ground. More than 10 wired and wireless network cameras, wired and bluetooth headsets, mobile phones, tablets, and laptops in the space station can all be used as terminals to connect to the network and access control anytime, anywhere.

More convenient is that each astronaut has a handheld terminal that can remotely control the microwave oven in the “kitchen” and the scene lighting in the cabin.

In addition, the space station cargo system uses QR code technology. The material packages on the cargo spacecraft carry a QR code. You can scan to understand how each package is classified and what is inside. What’s installed.

Space station working hours Long and tight staff, many things have to be “do it yourself, with plenty of food and clothing.” The astronauts also serve as barbers, photographers, and doctors.

In space, bathing and shaving can be done by yourself, but haircuts are best to cooperate with each other. In order to straighten each other’s hair, the astronauts practiced on the ground many times. In order to solve the problem of hair floating in the weightless environment of space, the space fader is covered with something similar to a vacuum cleaner, and the cut hair can be sucked in at any time.

Experience in space is rare, and you need to take pictures to leave precious moments. On the morning of August 20th, Nie Haisheng and Liu Boming conducted their second out of the capsule. The ground commander shouted to the two astronauts to take a picture of each other. So the two pointed their cameras at each other and captured the rare scene.

The physical health of the astronauts affects people’s hearts. In addition to the medical inquiry call once a day, the astronauts themselves are also half doctors, and can skillfully operate more than a dozen pieces of medical equipment in the core capsule, and perform routine medical examinations such as blood sampling, laboratory tests, and ultrasound.

In the public video, the scene of the physical examination of the three astronauts is shown in detail. We can see that all the lights in the Tianhe core cabin are turned off, and Tang Hongbo goes in the dark to perform a fundus examination for Liu Boming.

3-bit aerospace In the space station, the astronauts wished Tanabata blessings

Space blessings are also a traditional practice of astronauts. The mission lasted from July to September, during which it experienced several major festivals and activities, and each time there were blessings from the astronauts from far away.

On the eve of July 1st, three astronauts sent videos from the space station, representing the Chinese astronauts to send the most remote and sincere blessings to the centennial of the party. The video of just a few seconds instantly went to the front row of the hot search.

On the day of the Qixi Festival, three astronauts sent greetings-“The Cowherd and the Weaver Girl are reunited in Tianhe, we send blessings to everyone in Tianhe Capsule, and wish everyone happiness in the Chinese space home! ”

Watching Olympic events in the space station brings a lot of fun to busy work. The astronauts specially expressed their blessings to Chinese athletes participating in the Tokyo Olympics through video. Athletes such as Gong Lijiao and Su Bingtian also interacted with astronauts across the world in the form of video.

On the day when Liu Boming and others entered the space station, foreign astronauts also sent greetings from the space. The French astronaut Thomas Pesquet, who was on mission on the International Space Station, sent Twitter “as China sent three astronauts.” Their space station, the space population increased by 43% this week. Space flight is an incredible achievement. I can imagine the three of them admiring the scenery of Beijing and Tianjin from orbit.”

In a blink of an eye, 90 days The mission is nearing completion. The Shenzhou XII spacecraft will be “awakened” again, carrying three astronauts back to Earth.
