The Shenzhou-20 crew aboard China's orbiting space station -- astronauts Chen Dong, Chen Zhongrui and Wang Jie -- continued various space science experiments and tests.
In the field of space medicine, the crew used electroencephalogram devices to conduct experimental tests covering a variety of projects, such as upper visual field studies and lower visual field studies , executive function training, and exploratory utilization research.
Last week, the crew used equipment such as eye trackers and testing software needed to conduct experiments on microgravity relational cognition and human-machine trust and collaboration in space.
This activity helps researchers on Earth advance their studies of how microgravity affects relational cognition and its underlying mechanisms, as well as capture patterns in the evolution of astronauts' trust in artificial intelligence (AI)-based assistants during long-duration spaceflight in orbit.
The three astronauts also underwent ultrasound examinations of their blood vessels.
By collecting data on morphological characteristics, hemodynamic parameters, and functional metrics in various human organs and systems over varying durations in orbit, they aim to improve our understanding of how blood flow patterns evolve within the entire vascular network of the human body under weightless conditions.
In the area of human factors technology research, the crew conducted tests and collected data in orbit to study how operational forces vary with typical long-term postures in orbit.
They compare and analyze the differences between the Earth and space environments for various types of operational forces, such as push-pull and rotational forces, along with their variations within orbits, thus helping to identify the mechanisms behind these changes.
In addition, astronauts installed and tested a universal biological cultivation module in the life science and ecology experiment cabinet on the Chinese space station, laying the foundation for future research in space life science.
While carrying out these scientific activities, the crew also actively maintains equipment on the space station and implements health protection measures.
