The Shenzhou-19 Crew on board China's Space Station performed work related to experiments on the technology of artificial photosynthesis for extraterrestrial survival.

The crew used sampling cans to collect samples of reactants inside relevant devices and stored the samples to be brought down to the earth.

They also cleaned non-container experimental chambers, replaced experimental samples and maintained axis mechanisms and electrodes.

They also carried out medical rescue exercises, and emergency evacuation in the event of fire in space station.

The crew replaced circulation pumps of fluid loop system for space applications as planned, amongst other tasks.

The fluid loop system for space applications serves as a crucial mechanism within a space station for controlling and regulating the temperature of application system payloads, which ensures the smooth space science experiments.
