[Site] "God 15" Crew Expedition Ceremony
[Explanation] On November 29, three astronauts, Fei Junlong, Deng Qingming, and Zhang Lu, led the expedition and flew into space on the Shenzhou 15 manned spacecraft.
This is the final battle of the construction phase of China's space station, and it is also the first time that China has realized the combined structure of six types of cabin sections of the space station and the presence of six astronauts in orbit.

This is the first on-orbit rotation in our country, and the first face-to-face handover of the crew.
Although the time is about 5 days, but from 3 people to 6 people, this is indeed very significant.
For the space station system, it is mainly the assessment of regenerative life insurance, regenerative life insurance (regenerative life support system), and environmental control, such as temperature and humidity control, because there are too many people, temperature and humidity control, and urine system processing , Electrolysis of oxygen, control of harmful gases, and microbial control.
But you don’t have to worry, because at the beginning of the design of the space station, the co-orbit status of 6 people was considered, and relevant experimental verification was completed to ensure the common comfortable life of the astronauts in orbit.
【Live】Rocket launch
[Explanation] The temperature in Jiuquan in winter reaches about minus 20 degrees. This is the first time that China has launched a manned rocket at such a low temperature.
After the "Shenzhen 15" is launched, it will be docked at the space station at the same time as the "Shenzhen 14" spacecraft.

During crew rotation, the two manned spacecraft dock at the same time, and the space station also needs to provide grid-connected power supply information and ventilation and heat support to the two manned spacecraft, which is also an assessment of the space station’s operational capabilities.
After the completion of this mission, basically the space station is the largest configuration with 3 cabins and 3 ships.
The combination of six aircraft has also reached the largest scale that the space station can accommodate visiting aircraft at this stage. The entire combination is nearly 100 tons, and the living space of the astronauts will reach an unprecedented 100 cubic meters.
[Explanation] On November 30th, the Shenzhou 15 manned spacecraft successfully docked with the space station assembly that formed the basic configuration of the "T" character. Afterwards, three astronauts entered the space station and successfully joined forces with the crew of Shenzhou 14. .

The Chinese space station is always worth looking forward to!
