Shenzhou-19 Crew Update: Research & Maintenance Tasks | China Space Station
China's Shenzhou-19 crew members have completed a range of tasks during their over-one-month stay aboard the orbiting Tiangong space station, including scientific research and experiments and space station maintenance work.
The crew members—Cai Xuzhe, Song Lingdong, and Wang Haoze—were sent into the Tiangong Space Station on October 30, 2024, for a six-month mission.
During their flight, the three astronauts will conduct 86 space science research and technology experiments.
During research on the biological effects and molecular mechanisms of fruit flies under a weak magnetic field in space, the crew completed operations, including clearing petri dishes for the fruit flies and replacing the gas purification components in the life science experimental facility.
For a research project on how stem cells undergo three-dimensional growth and tissue generation in microgravity, the crew completed the collection and storage of cell experiment samples, laying a solid foundation for future applications of stem cell three-dimensional tissues and for conducting space drug screening using these tissues.
Meanwhile, ongoing research is being conducted on the impact of phase separation of biological entities on lipid metabolism in microgravity.
The crew members have also conducted several other tasks, including replacing the burner inside the combustion science experimental cabinet, setting and restoring the states of vacuum extraction and exhaust emission, as well as replacing samples in the fluid physics experimental cabinet.
In the field of space medicine experiments, the crew members employed a visual function measurement instrument, an eye tracker, and visual gravity representation testing software to conduct research on the representation and dynamic processing mechanisms of gravity in visual motion.
This research delves into the influence of gravity environments on the sensitivity of human visual biological motion perception and how weightlessness changes these perceptual sensitivities. It aims to provide a scientific basis for human exploration in deep space and adaptation to diverse gravity environments in the future.
To ensure a long-term stable operation of the space station, the crew members have completed the installation of forward and aft hatch protection devices against space debris. Through physical shielding, these devices effectively mitigate the adverse effects caused by impacts from small space debris on the hatches.
Additionally, the astronauts have also completed tasks such as cleaning, inspecting maintenance in each module, and sorting supplies on the space station and the Tianzhou-8 cargo spacecraft.
