At the first exhibition of Chinese astronauts flying photography, which opened on July 26, Yang Liwei, deputy director of the Aerospace Heroes and Manned Space Engineering Office revealed that China will start the selection of the third batch of astronauts this year. Different from before, this time, we will face the community and select engineers and researchers who have engineering backgrounds. They will serve as space stations, spacecraft maintenance, repair, assembly, outboarding and other missions in future space missions.
China's manned space station plan will be assembled and put into operation around 2022, and large-scale space science experiments and technical tests will be conducted.
After the manned space station is completed, the astronaut's residence time will be extended to 3-6 months, and a large number of scientific experiments and space station maintenance and repair tasks will be completed. This poses new challenges to the astronauts' knowledge and training.
According to the latest disclosure, the basic configuration of China’s space station includes a core cabin and two experimental cabins, each weighing more than 20 tons, with a symmetrical T-shaped configuration, rated members of 3 people, and up to 6 people during the group rotation.
There are five pairs of ports in the core cabin, which can be used to dock a cargo spaceship, two manned spacecraft and two experimental cabins, and a hatch for the astronauts to go out of the cabin.
The China Space Station is equipped with scientific experiment cabinets with international standard interfaces in one core and two experimental cabins for conducting various kinds of space science experiments. The main fields include: space life sciences and biotechnology, microgravity fluid physics and Combustion Science, Space Materials Science, Microgravity Fundamental Physics, etc.
Yang Liwei had previously stated publicly that during the construction phase of the manned space station, China will conduct more than four manned missions.
In addition, China will also develop space astronomical telescopes that emit a 2-meter aperture, which can be used for large-scale, multicolor imaging and seamless broad-spectrum surveys.
