Tianzhou-4 spacecraft was successfully launched to deliver urine processing subsystem consumables to the space station

　　China News Service, Beijing, May 10 (Ma Shuisha) On May 10, the Tianzhou-4 cargo spacecraft was successfully launched into orbit at Wenchang Space Launch Site. The spacecraft was loaded with more than ten pieces of calcium removal components, urine filter components, etc. Consumables required for the Urine Conservation Subsystem for Environmental Control of the Space Station.

　　It is reported that this batch of spare parts was developed by the 206 Institute of the Second Academy of China Aerospace Science and Industry Corporation, and will be used as consumables for the normal operation of the space station's environmental control and urine-preserving processing subsystem.

In the future, after the Shenzhou 14 crew is stationed in the Chinese space station, routine maintenance work will be carried out on the urine processing subsystem, and consumables such as calcium removal components, urine filter components, and lubricating water bag components will be replaced.

At 1:56 on May 10, the Long March 7 Yao-5 carrier rocket carrying the Tianzhou-4 cargo spacecraft was successfully launched at the Wenchang Space Launch Site in China.

　　The urine processing subsystem is an important part of the space station's environmental control and health protection system. It was developed by the 206 Institute of the Second Academy of China Aerospace Science and Industry Corporation over a period of ten years. It is one of the iconic key equipment for long-term presence of crew members in orbit, and plays an important supporting role in the construction and operation of the space station.

　　So far, the prototype of the urine processing subsystem Tianhe has been in orbit for more than one year. The research and development team of the urine processing subsystem of the 206th Institute of the Second Academy of China Aerospace Science and Industry Corporation analyzed the changes of various parameters of the urine processing subsystem during the orbital flight. , summed up the effect of the difference of heaven and earth on the performance and parameters of the urine processing subsystem, and optimized the subsystem control software.
