According to the China Manned Space Engineering Office, the second lesson of the "Tiangong Classroom" will be held at 15:40 today (23rd) on the China Space Station, and the Shenzhou 13 crew astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu will cooperate with each other to teach. This is also the third time that Chinese astronauts have taught space.
What is this lesson about? Take a look at the curriculum: At that time, astronauts will demonstrate space "ice and snow" experiments, liquid bridge demonstration experiments, water and oil separation experiments, space parabolic experiments, introduce and display space science facilities, and there is also a space-earth interaction link, astronauts sincerely invite all sectors of society, especially the majority of young people, to try to carry out relevant experiments on the ground. In this lecture activity, CCTV will broadcast live to the world.
The Star Sea Boy said
With the mainland making more and more breakthroughs in the field of aerospace, it has also attracted more and more teenagers to look at the stars and the sea. For the upcoming "Tiangong Classroom", what kind of imagination do teenagers across the country have? We listen to them.

What are you most interested in about the space station?
Ye Zi, a student of Deai School in Jiangdong New District, Heyuan City, Guangdong Province: Space is a weightless state, if you blow a balloon on the earth, it will fall, if you blow a balloon with your mouth in space, will it rise?
Zheng Zitao, a student of Victory School in Huidong County, Huizhou City, Guangdong Province: On the space station, if the water droplet is a suspended state, you can use the ping-pong ball to hit the water droplet, will it have a rebound effect?
Yu Zaiyuan, a student at the Wuzhou Foreign Chinese School of Zhejiang Normal University: What I am most interested in is that air convection cannot be generated in a microgravity environment, so how do they boil water?
Huang Xinyi, a student at Sichuan Zigong Bancang Experimental School: For example, raising small animals on the space station to see if these small animals live on the space station and are the same as on the earth, very energetic.
Zeng Shiyi, a student at Dongshan School in Meizhou City, Guangdong Province: I heard that when the space capsule returns to the earth, it uses the return method of water drifting, so what is the difference between this and the ordinary way of return?

If you could get into the space station, what would you most like to do?
Zheng Jiaying, a student at Wuzhou Foreign Chinese School of Zhejiang Normal University: I most want to experience space cycling, because in the last class, Teacher Wang Yaping showed us the space bicycle handstand to exercise his upper limbs. And on Earth it is very difficult for us to stand upside down.
Cai Jinghan, a student at The 15th Middle School in Yinchuan City, Ningxia: I prefer to draw, so I want to consider whether painting on the space station will have a different feeling, and I can paint those planets in space.
Ma Ningmei, a student at Yinchuan No. 15 Middle School in Ningxia: I want to try to bring the watermelon up, to see if the watermelon will become bigger, or become a pocket watermelon. Animals, I'd like to try to bring an orangutan up there, because orangutans and humans behave very similarly, and it will not have some unique reactions.
Gao Haiyuan, a student at Deai School in Jiangdong New District, Heyuan City, Guangdong Province: I want to try whether the water flowing from the water gun is in the shape of a water column or a water droplet, because I saw a video before that the water flowed out and became a state of water droplets, and then I wanted to try to see if it would also become the form of water droplets in the high-speed state of the water gun.
Ye Kaixin, a student at Deai School in Jiangdong New District, Heyuan City, Guangdong Province: If I have the opportunity, I want to shoot a shot in space, and I want to see if the bullet in space will slow down, or stop.

What experiment would you most like to do on the space station?
Cai Jinghan, a student of The 15th Middle School in Yinchuan City, Ningxia: The friction experiment, I think the friction in space should be different. Because in space, its gravity is not the same, and there is a balanced relationship between the forces.
Zheng Jiaying, a student at Wuzhou Foreign Chinese School of Zhejiang Normal University: I most want to use a glass rod to stir the water in the cup, how will the water react? Because in the last class, we can observe that the surface tension of water is very magical in microgravity.
Xu Chunyi, a student at Jiaojiang No. 5 Middle School in Taizhou City, Zhejiang Province: What I want to do most is whether oil and water can be (like) layered normally on Earth.
Li Mingsheng, a student at Jiaojiang No. 5 Middle School in Taizhou City, Zhejiang Province: The experiment I most want to do is to explore the development of plants in the weightless state, and I want to understand whether the stems and leaves of plants will be affected by the development of weightlessness.

Shenzhou 13 astronauts completed several missions in orbit
Since the launch of the Shenzhou 13 manned spacecraft on October 16, 2021, the Shenzhou 13 astronaut crew has been in orbit for more than 5 months, during which it has completed a number of space experiment missions and created a number of records.
At 0:23 on October 16, 2021, astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu flew into space from the Jiuquan Satellite Launch Center in a Shenzhou 13 manned spacecraft. At 6:56 a.m., the spacecraft and the space station complex completed an autonomous and rapid rendezvous and docking. At 9:58, three astronauts entered the Tianhe core module.
On November 7, 2021, the Shenzhou 13 astronaut crew ushered in their first outgoing activity.
Shenzhou 13 astronaut Zhai Zhigang: I am 01, I have been out of the capsule, I feel good.
Shenzhou 13 astronaut Wang Yaping: I am 02, I will come out of the capsule, I feel good.
Shenzhou 13 astronaut Ye Guangfu: I am 03, the next time I go out of the capsule, I feel good.
At 20:28, astronaut Wang Yaping successfully exited the capsule from the Tianhe core module node module, becoming the first female astronaut in China to carry out the outgoing activities, and taking the first step in China's female extravehicular spacewalk.
On the afternoon of December 9, 2021, the first lesson of "Tiangong Classroom" was officially launched, and Shenzhou 13 astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu brought a wonderful space science popularization class to the majority of teenagers on the China Space Station. This is the first space teaching activity of the Chinese space station.
In about 60 minutes of lectures, the astronauts introduced and demonstrated the work and life scenes of the space station, demonstrated the miraculous phenomena of cytology experiments in microgravity environment, human movement, liquid surface tension, and explained the scientific principles behind the experiments.
At 18:44 on December 26, 2021, Shenzhou 13 astronaut Ye Guangfu successfully opened the door of the Tianhe core module node, and subsequently, astronauts Ye Guangfu and Zhai Zhigang successfully left the capsule to coordinate the tasks of C lifting of the space station's extravehicular panoramic camera, installation of the extravehicular operation point and foot limiter, and related ergonomic verification, and verification of the transfer of carrying materials.
On New Year's Day 2022, more than 500 young students from Beijing, Hong Kong and Macao gathered together across time and space to communicate with astronauts and aerospace science and technology workers in real time.
At 7:55 on January 8, 2022, the Shenzhou 13 astronaut crew, under the close coordination of ground scientific and technological personnel, adopted a hand-controlled remote operation method and successfully completed the rendezvous and docking test of the Tianzhou-2 cargo spacecraft and the space station combination. This test is the first time that astronauts have used hand-controlled remote operation equipment in orbit to control the cargo spacecraft and the space station to rendezvous and dock, which initially verifies the function and performance of the manual remote operating system of the space station and the visiting aircraft, as well as the rationality of the cooperative working procedure between heaven and earth.
