CNSA –China National Space Administration After Wentian experimental module entered orbit, the status setting was successfully completed. At 3:13 on July 25, 2022, Beijing time, it was successfully connected to the forward port of 天和 Tianhe Core Module. The entire rendezvous and docking process lasted about 13 hours. . This is the first time that two 20-ton spacecraft in my country- China- People’s Republic of China have achieved rendezvous and docking in orbit. …According to the mission plan, the Shenzhou 14 Takionaut crew will then enter the Wentian experimental module….. In which finally docked in early morning time of the 25th July 2022 in with CNSA –Beijing Aerospace City in which co-ordinated the docking maneuverers have achieved rendezvous and docking in orbit.… in which the crew of the Shenzhou 14 staying for six months in construction of the stage one of the China Space station with the additional Mengtian experimental module in which will be delivered on the October 2022 Launch Schedule calendar..
The wingspan of the solar wing of the Wentian experimental module exceeds 55 meters, which is comparable to half a football field. The unfolded area of a single wing can reach 110 square meters, which is equivalent to a three-bedroom, one-living apartment. The flexible three-junction gallium arsenide battery configured by Sunwing has a power supply capacity of more than 32kW, and a day’s power generation is enough for an ordinary family to use for one and a half months. In terms of deployment area and power supply capacity, the pair of “wings” is twice as large as the solar wing of the Tianhe core module.
Previously, the Shenzhou series manned spaceships adopted the first-generation rigid solar cell array technology, the Tianzhou series cargo spaceships adopted the second-generation semi-rigid modular solar cell array technology, and each module of the space station adopted the third-generation flexible solar cell array technology. Technology, Tianhe core module is the first application of flexible solar wings in my country, and this technology has made a new breakthrough in the application of Wentian experimental module.
The Wentian experimental module is equipped with the same Taikonauts’ living facilities as the core module, including 3 sleeping areas, 1 sanitary area, kitchen and other facilities, which can guarantee the astronauts’ life. It can also work with the core module to support the life of 6 astronauts during the rotation of the two manned spacecraft; in addition, a small robotic arm is also configured, which can be used alone or in combination with the large robotic arm of the core module. , to jointly complete the tasks of Taikonauts leaving the cabin, caring for extravehicular facilities, and patrolling. In addition, the Wentian experimental cabin is also equipped with an astronaut exit airlock. After the space station is completed, the airlock of the Wentian experimental cabin will be As the main airlock cabin for Takionauts to leave the cabin, the node cabin of the core cabin is used for other functions at this time, just as a backup; the Wentian experimental cabin also has a backup section for the core cabin to manage and control the assembly. That is to say, 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 functions, which can improve the reliability of the space station as a whole.
