Shenzhou 14th astronauts came out of the cabin for the first time!The new "home door" is dazzling
Author:Global Times Time:2022.09.03
[Global Times Comprehensive Report] At 18:26 on September 1, Beijing time, Chen Dong, Shenzhou 14, the Shenzhou 14 on the China Space Station, successfully opened the outlet door of the Tiangtian Experimental Countercat. At 19:09, astronauts Chen Dong and Liu Yang successfully got out of the cabin. Two out -of -the -cabin astronauts complete the installation of the foot limiter and the outside workbench, and will follow the support of the small robotic arm. And carry out the capability verification of an emergency return on the outside of the cabin. This is also the first time that the astronauts have "went out" from the air gates compartment of the test compartment. According to a reporter from the Global Times, this air gate can also become the main outlet channel of the entire space station system in the future.
As a new "door" on the China Space Station, the visual effect of the Sky Experimental Counterbiography is very unique, showing the characteristics of the internal circle of the outside world. This is also the only cabin that looks square in the space station system.
According to a reporter from the Global Times, the outside of the air gate and the appearance of a square shell is an exposed experimental platform outside the cabin. Li Yan, director of the Space Technology Experimental System of the Five Hospital of Aerospace Science and Technology Group, said in an interview with the media that the square flat plate structure is mainly to facilitate the robotic arm to grasp the load and install it on this platform. On the other hand, the load has a specific direction requirement, which can ensure a load observation field.
"Global Times" learned from the space station asked the Tianjin Experimental Counter to grasp the Fifth Hospital of Aerospace Technology Group of the General Development Unit. Asked about the 5 -meter -long "small arm" outside the air gate. This set of 7 -degree -of -freedom robotic arm is small and highly accurate. "Small hands" are convenient to grasp small and medium -sized equipment and do more fine operations. Astronauts can use human -machine interoperability to complete the space robotic arm multi -mode operation in the cabin. In addition, the arm can also form a 15 -meter -long combination arm with the core cabin armor to carry out more off -cabin operations. In the next ten years, the scientific experimental load equipped in the space station can accurately "send" the mechanical arm to the corresponding standard load interface position of its own, and achieve "plug -in and play", and no longer requires spaceholders to operate artificial operations.
The "locker room" when the spaceman launched the cabin -out -of -the -cabin air gate was cylindrical. The "locker room" on the test cabin is more space. When the astronauts make preparations and return outside the cabin here, they can be more stretched and calm. Earlier, Shenzhou 12 and Shenzhou 13 multiplication group performed the outlet mission through the outlet and mouth of the core compartment of the space station. As for the caliber of the Tianshi experimental compartment door, the astronaut only needs to use the operation handle to unlock the operating handle on the door of the door. Use the helping agency to eliminate the pressure. Action. The astronauts from here are not only more convenient, but they can also carry large heads to work out of the cabin, which greatly improves work capacity.
According to a reporter from the Global Times, China Space Station was independently built by my country, realizing all domestic products, all domestic components, all localized raw materials, and 100%of key core components. It is worth mentioning that in the cabin activities before the Chinese Space Station era, the "lifeline" of the aerospace staff and the space station -the length of the safety line is limited. For example, in Shenzhou VII mission, when the astronauts Zhai Zhigang completed the first out -of -cabin event in my country, the effective length of the safety line was only more than 1 meter. In the construction task of the space station, astronauts must complete the outlet tasks such as space station equipment installation and maintenance. The outlet range is larger, the operation difficulty is more difficult, and the safety requirements are stricter. In the process of coming out, the length of the safety rope has exceeded 10 meters. Under the innovative design of the R & D team, this safety rope will not only have the movement of hooking and interference in aerospace officers, but also to withstand the aerospace suit. The test of nearly 200 degrees of temperature difference and spatial radiation in space in space. It can also achieve constant force and release, ensuring the convenience and mobility of astronauts.
