"Hello, classmates! We are connecting with you at the Chinese Space Station about 390 kilometers away from the surface of the earth. At this moment, our Tianhe Core Module is passing over the sky of the motherland!"
Shenzhou Ten A sonorous opening remark by the commander of the second task force Nie Haisheng opened the prelude to the "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 the full implementation phase. 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. marked 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.
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 are invited to bring a special lesson to the students.
Nie Haisheng’s Tai Chi class has started.
Rising power, holding fists, 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. Besides,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, speaking with a strong northeast accent, 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 bedroom 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.
The picture hung on the head of Liu Boming's bed with the family portrait. After he got out of the cabin, he saw the Bohai Bay of the motherland on the robotic arm, which was an improvisational work. 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 is a group photo of astronauts from the Chinese People's Liberation Army astronaut battalion .
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. The surface tension is not significant, but in the microgravity environment, the liquid surface tension is enough to make the tea condense into small water balls visible to the naked eye. In the air, at the same time, there is a certain degree of adhesion between the chopsticks and the water, so you can easily eat the tea with the chopsticks.
The opening message of the space travel trio, please check
"My little man, the road to life is very long. Don’t give up your dreams because of difficulties and obstacles. Life needs continuous improvement, and the future is also Always full of hope. I believe that in the near future, when we meet, we will definitely be a better version of ourselves." This is what Tang Hongbo wants to say to his son.
"As soon as I flew over here, I thought of hundreds of millions of people supporting us, and they were supporting us to fly higher and higher!" This was Liu Boming's sigh when he saw the sky over the motherland through the porthole.
Ideals not only light up the road signs leading to our dreams in life, but also set up a ladder to the firmament of the universe. From Quyuan’s release of " Tianwen" to "Tianwen 1" landing on Mars, from Chang'e flying to the moon to "Chang'e 5" retrieving the lunar soil, the Chinese have held on to their dreams for thousands of years. Today is one This has become a reality!
