According to CCTV reports, at the Shenzhou 14 manned mission press conference this morning, it was officially announced that three astronauts, Chen Dong, Liu Yang and caixuzhe, would carry out the Shenzhou 14 manned mission, with Chen Dong as the commander. The mission headquarters decided to launch the Shenzhou 14 manned spacecraft at 10:44 Beijing time on June 5.
In addition, at this press conference, the official also announced that during the Shenzhou 14 mission, the construction of the space station with the basic configuration of the Tianhe core module, the sky inquiry experimental module and the dreamsky experimental module will be fully completed, and the national space laboratory will be built.
In April this year, the manned space Office introduced the situation of the two experimental modules, Wentian and Mengtian.
The sky inquiry experimental module is equipped with the same living facilities for astronauts as the core module, including 3 sleeping areas, 1 health area, kitchen and other facilities, which can ensure the life of astronauts It can also support the lives of six astronauts during the rotation of two manned spacecraft together with the core module
In addition, a small mechanical arm is also configured, which can be used alone or in combination with the large mechanical arm of the core module to jointly complete the tasks of astronauts' exit, care of extravehicular facilities, patrol inspection, etc.
In addition, the sky test module is also equipped with an astronaut exit airlock. After the space station is completed, the airlock of the sky test module will be used as an airlock for astronauts' main exit activities. At this time, the node module of the core module is used for other functions, but only as a backup; The sky test module also has a backup module for the core module to manage and control the assembly.
In other words, when the function of the core module platform fails, it can be switched to the Wentian experimental module to exercise the combined control and management function, which can improve the reliability of the space station as a whole.
The dreamsky experimental module is equipped with a cargo airlock and an extravehicular deployment test platform. In the future, the scientific test equipment that needs to be installed outside the cabin can be transported to the space station by the cargo spaceship, and then the load can be sent outside the cabin by the cargo airlock, and it can be installed on the platform outside the cabin by the mechanical arm or astronauts. In this way, the extravehicular test projects can be continuously updated.
