China's Shenzhou-18 crew has successfully conducted a routine maintenance of the country's Tiangong space station, marking 1,200 days of safe and stable operation, a recently released footage showed.
The Shenzhou-18 crew has conducted scheduled measurements of the station's internal vibration environment, a procedure crucial for improving the comfort of astronauts living in orbit and enhancing the reliability of the space station by effectively controlling vibrations.
In terms of equipment maintenance, the crew tested the functionality of smoke detection sensors aboard the station.
Using specialized tools, they activated the detectors, triggering alarms that included voice alerts, lights, and gauges to assess the sensitivity and accuracy of the fire detection system.
In addition, the crew performed inspections of portable scientific experiment monitoring devices and completed maintenance tasks related to the regenerative life support systems, including electrolytic oxygen production and component replacements.
The electrolytic oxygen generation system is vital for controlling the oxygen partial pressure within the station. It electrolyzes water provided by the station's water treatment system to produce oxygen and hydrogen, supplying the necessary oxygen for astronauts to breathe.
Between maintenance tasks, the astronauts at the space station engaged in rendezvous and docking training, utilizing a meta-cognitive training system to complete image recognition exercises under varying initial conditions, preparing for the visits by subsequent spacecraft.
