The fourth space lecture "Tiangong classroom" on the Chinese space station was a complete success.
CTOnews.com, September 21, according to the manned Space Office, the fourth lesson of "Tiangong classroom" began at the China Space Station this afternoon. The new "space teachers" Jing Haipeng, Zhu Yangzhu, and Gui Haichao brought a wonderful space science lesson to the vast number of young people. This is the first time that Chinese astronauts have taught in the Mengtian experimental module. The fourth space lecture activity of the Chinese space station was a complete success.
This space teaching activity continues to be conducted in the form of interaction between heaven and earth. The three astronauts will show and introduce the working and life scenes of the Mengtian experimental module of the Chinese space station, demonstrate the spherical flame experiment, the wonderful "table tennis" experiment, the momentum conservation experiment and the gyroscope experiment, and interact with the ground classroom. The summary part of CTOnews.com is as follows:
In the first part, the crew of Shenzhou 16 astronauts will introduce the brand-new "space classroom"-Mengtian experimental module, including the "space alchemy furnace" high-temperature material science experiment cabinet, and the ultra-cold atomic physics experiment cabinet whose temperature is close to absolute zero.
In the second part of the spherical flame experiment, in the space station, the buoyancy convection is almost eliminated in the microgravity environment, and the trend of the burned gas is the same in all directions, so the flame is nearly spherical no matter where the candle is oriented. In addition, candles on the space station do not burn as fully as candles on the ground, and the temperature is colder.
The third part of the wonderful "table tennis" experiment, what equipment is needed for a "space station table tennis friendly match"? Using an ordinary racket, the water polo "ping-pong ball" is firmly glued to the racket; with the use of towels, the water polo is not absorbed, but bounces away.
