What is the "three rooms and two halls" China Space Station like?

The basic configuration of China Space Station includes Tianhe core module, Quest module and dream module, and the overall configuration is T-shaped. The total length of the Tianhe core cabin launched this time is16.6m, the maximum diameter is 4.2m, and the launch mass is 22.5t.. As the management and control center of the future space station, Tianhe can support three astronauts to stay in orbit for a long time and carry out space science experiments and technical experiments inside and outside the cabin.

From the functional point of view, the core cabin has the ability of rendezvous and docking, transposition and parking, long-term residence of crew, astronauts' exit and space science experiments. Both candlestick and Meng Tian experimental module are used as load support modules to support large-scale space science experiments and technical experiments inside and outside the module. At the same time, the candlestick experimental cabin is also used as a backup cabin to control and manage the assembly, which has the ability to leave the cabin, while the Meng Tian experimental cabin has the ability to automatically enter and leave the cabin.

If it is difficult to clearly outline the appearance of China's space station just by looking at the data, space experts have a more vivid description. Experts from the Fifth Academy of Aerospace Science and Technology Group said that the core cabin is very large, its length is higher than five stories, its diameter is much wider than that of trains and subways, and its volume is larger than any single cabin of the International Space Station.

After the future astronauts settle in, the activity space is very spacious. In addition, the weight of the core module is equivalent to the empty weight of three buses, and it also exceeds any module of the International Space Station. Experts made a very vivid analogy: If shenzhou spaceship is a car, Tiangong No.1 and Tiangong No.2 are equivalent to a house with one room and one living room, while the space station is a "mansion" with three rooms and two living rooms and storage rooms.

Not only is there a large space for activities, but the supply of China astronauts in the future space station will also be better guaranteed. Previously, China astronauts spent up to 33 days in orbit, and the water and oxygen necessary for astronauts' survival were directly sent into space by spacecraft. In order to make astronauts stay in orbit for a longer time, the space station is designed with a complete renewable life support system.

The water vapor exhaled by astronauts will be recovered by condensed water, and the discharged urine will be recovered and purified for reuse as drinking water and domestic water. Hydrogen produced by electrolysis and carbon dioxide exhaled by astronauts will generate oxygen through chemical reaction, which can also reduce the demand for oxygen supply.

The future space station will be equipped with various scientific research and experimental facilities.

The reporter learned that due to the precious resources of the space station, the future space station will be equipped with scientific and experimental facilities including biology, materials science, basic physics, microgravity, fluids and other related categories after scientific and careful selection. It is reported that more than 10 advanced scientific experiment cabinets and extravehicular load installation platforms will be deployed on the space station.

According to experts, the optical module that will fly with the space station will be equipped with a sky-survey telescope. The resolution of this telescope is equivalent to that of the American space telescope, but its field of view is hundreds of times that of the latter. It will play an important role in the large-scale scientific research of sky survey.
