Shenzhou 20 astronauts – Chen Dong, Chen Zhongrui and Wang Jie – are pushing forward with wide-ranging scientific experiments and technology tests aboard China’s space station, advancing knowledge across multiple research domains.
In space medicine, the crew used electroencephalogram equipment for experiments including visual field studies, executive-function training and exploratory utilization projects. They also employed eye-tracking devices and specialized software to investigate microgravity’s impact on relational cognition and on how astronauts develop trust in AI assistants during extended missions.
The astronauts underwent vascular ultrasound scans, gathering data on organ morphology, blood flow dynamics and functional measures across different mission durations. These findings are expected to improve understanding of how the human circulatory system adapts to long-term weightlessness.
In human-factors technology studies, the crew analyzed operational forces such as push-pull and rotational movements in microgravity, comparing them to terrestrial conditions. This work helps clarify the mechanisms behind variations in astronaut performance over time in orbit.
They also installed and tested a universal biological cultivation module inside the station’s ecological experiment cabinet, creating new opportunities for life science research in space.
Alongside these experiments, the crew continues to maintain station systems and follow health protection protocols to support safe, sustained operations.
