"Hello, classmates! We are now connecting with you at the China Space Station, which is about 390 kilometers away from the surface of the earth. At this moment, the Tianhe core module where we are located is passing over the motherland!"

  A sonorous and powerful opening remark by the commander of the Shenzhou 12 task force Nie Haisheng opened the prelude to this "connection between heaven and earth".

  On April 29, 2021, the Tianhe core module was successfully launched, marking that the construction of the Chinese space station has entered a full implementation stage.

On June 17, the three astronauts Nie Haisheng, Liu Boming, and Tang Hongbo took the Shenzhou XII spacecraft into space and successfully entered the space station,

marking the first time that Chinese settled in our own space station

.

After five years, when the new generation of Shenzhou manned spacecraft once again carried astronauts into space, it has completed further optimization and upgrades, and has upgraded its comprehensive capabilities to a new stage.

  And this year's "First Class of School" moved the classroom to space for the first time. Through the "World Connection", three astronauts in the space station were invited to bring a special lesson to the students.

Nie Haisheng’s Tai Chi class has started

  Starting momentum, holding fist, Zhou Tian...These are all the movements of "Tai Chi" taught by Nie Haisheng in "The First Lesson of School".

Because of the weightlessness, Lingbo's microsteps and flying over the wall, these martial arts novels, astronauts can easily perform in space, but these "movements" cannot effectively exercise physical functions.

For training on different parts of the body, the astronauts prepared a wealth of fitness equipment, and even carried the self-developed treadmill into space for the first time.

In addition, there are also physical exercise activities such as "Tai Chi".

Liu Boming's space vlog is online again

  "Please follow me to roam the space station!" Liu Boming spoke with a strong northeast accent and readily agreed to the children's request to visit the space station.

  After briefly introducing the various installations in the kitchen, Liu Boming led everyone to the bedrooms of the three astronauts.

The first thing that comes into view is the calf doll hanging in front of Liu Boming's bedroom. Its appearance brings a touch of playfulness to the serious space station.

"It also undertakes two important missions. One is to turn things around and look forward to the early arrival of humanity's victory against the epidemic; the other is to be bullish, to show our crew's confidence and determination to complete the task!" Liu Boming told the Mavericks The extraordinary meaning.

  In addition, the three astronauts also showed the children other objects that followed them into space.

For example, Nie Haisheng's flute, Liu Boming's family portrait, Tang Hongbo's family portrait, and his wife's handwritten cards.

  Hanging with the family portrait on the head of Liu Boming's bed was an improvisational piece of work he saw on the robotic arm of the Bohai Bay of the motherland after he got out of the cabin.

The space station, the Bohai Bay, the Yangtze River and the Yellow River in the painting resemble a phoenix spreading its wings and soaring. Liu Boming named it "Legend of Phoenix".

  It is worth mentioning that Nie Haisheng took out a special "family portrait", which was

a group photo of all the astronauts of the Chinese People's Liberation Army astronaut brigade

Tang Hongbo challenged to hold tea with chopsticks

  Have you ever seen the scene of eating tea with chopsticks?

At the scene of "First Class of School", astronaut Tang Hongbo showed us this interesting phenomenon.

I saw Tang Hongbo holding a pair of chopsticks connected with a rope, picking up the "tea" floating in the space capsule like jelly, and eating it into his mouth like a vegetable.

There were bursts of applause and exclaim at the show.

  This is because the liquid has surface tension.

When on the earth, the liquid is greatly affected by gravity, and the surface tension is not significant, but in a microgravity environment, the surface tension of the liquid is enough to make the tea condense into small water balls visible to the naked eye, floating in the air, and at the same time, chopsticks There is a certain degree of adhesion between it and the water, so you can easily eat the tea with chopsticks.

"My little man, the road to life is very long. Don't give up your dreams because of difficulties and obstacles. Life needs continuous progress, and the future is always full of hope. I believe that in the near future, when we meet, we will all It's a better self."

This is what Tang Hongbo wants to say to his son.

  "As soon as I flew over here, I thought that there are hundreds of millions of people supporting us, and they are supporting us to fly higher and higher!" This is Liu Boming's sigh when he sees the sky over the motherland through the porthole.

  Ideals not only light up the road signs to our dreams in life, but also set up a ladder to the firmament of the universe.

From Qu Yuan’s "Tian Wen" to the "Tian Wen 1" landing on Mars, from Chang'e flying to the moon to the "Chang'e 5" retrieving the lunar soil, the Chinese people have held their dreams for thousands of years, and today one by one has become a reality!
