The Chinese space station astronauts out of the cabin for the first time! “beautiful”

This is the first time that the Chinese astronauts have performed an exit mission after the successful completion of the flight crew of the Shenzhou VII flight crew in 13 years.

This morning

Three astronauts on Shenzhou 12 coordinated

Carrying out the first out of the Chinese space station

This is following the Shenzhou 7 flight crew

After successfully completing the exit mission

After 13 years

Chinese astronauts once again perform out of the cabin mission

▼At 8:11 on July 4, 2021, Beijing time, astronaut Liu Boming successfully opened the exit door of the core module of Tianhe.

▼As of 11:02, astronauts Liu Boming and Tang Hongbo, wearing a new generation of “Flying” extravehicular spacesuits independently developed by China, have successfully exited from the node module of the Tianhe core module and have completed the installation on the robotic arm. The foot stopper and the extravehicular workbench will be supported by the robotic arm to cooperate with each other to carry out the assembly of related equipment outside the space station. During the period, the astronaut Nie Haisheng in the cabin cooperated and supported two astronauts out of the cabin to carry out extravehicular operations.

▼At 12:09, astronauts Liu Boming and Tang Hongbo coordinated to complete the lifting operation of the space station’s extravehicular panoramic camera.

Three astronauts with a clear division of labor

Astronaut missionOne of the two astronauts leaving the capsule (Liu Boming) has to install an upper arm support for the robotic arm, including a foot stopper, a tool table, etc., and then move it with the help of the robotic arm. Another astronaut (Tang Hongbo) used the handrails installed on the bulkhead to crawl a distance to the operating point for auxiliary work, during which an emergency return verification was required. The Chinese space station astronauts out of the cabin for the first time! "beautiful"The Chinese space station astronauts out of the cabin for the first time! "beautiful"Wang Yanlei, director of the selection and training room of the China Astronaut Research and Training Center: Because if an emergency occurs when an astronaut is doing some operations outside the cabin, the astronaut must quickly and urgently return to the airlock cabin, and then use our cabin. Emergency oxygen supply on board to ensure the safety of life, so it is also necessary to verify this aspect.Another important task of this outing activity is to raise the panoramic camera outside the cabin.The Chinese space station astronauts out of the cabin for the first time! "beautiful"Wang Yanlei , director of the selection and training room of the Chinese Astronaut Research and Training Center: Beforehand , the camera was installed in a relatively low position due to the limitation of the external exposure of the launch, and its field of view was still limited. After being in orbit, the aerospace According to mission needs, the crew needs to expand the camera’s viewing angle to monitor the entire situation outside the cabin, and the astronauts need to install a bracket for these cameras to be higher.In-vehicle astronaut missionWhen the two astronauts exit the cabin, the astronaut (Nie Haisheng) in the cabin needs to operate the robotic arm. Although ground personnel can also perform large-scale transfers of the robotic arm, when there are astronauts standing on the robotic arm, the cabin The inner astronauts can observe the position of the robotic arm more intuitively, and can communicate directly with the outer astronauts.The Chinese space station astronauts out of the cabin for the first time! "beautiful"Wang Yanlei, Director of the Selection and Training Office of the China Astronaut Research and Training Center: So at this time, because our ground monitoring methods are limited, we need to communicate via voice between the astronauts in the cabin and the astronauts outside the cabin. The astronauts inside use simulation software and the images he sees to make some judgments to control. 
In addition, the astronauts autonomously operate the robotic arm, which also has a better guarantee in terms of safety. Wang Yanlei, Director of the Selection and Training Office of the China Astronaut Research and Training Center: On the one hand, it is through the early warning function of our simulation software. On the other hand, both the extravehicular astronauts and the in-vehicle astronauts have emergency stop devices. If there is a possibility or risk of collision during the movement, he can directly press the emergency stop device, and the mechanical arm will stop working, which is also a multiple means to ensure safety. 
Through the astronaut’s first exit activity on the Chinese space station, the astronaut’s exit capability and emergency response capability can be effectively verified, especially when working outside the cabin for a long time. The combination of man and equipment provides the follow-up astronauts to maintain the space station. Valuable experience.
