Shenzhou-20 Crew Advances Mission in Productive Week | China Space Station
The ongoing Shenzhou-20 mission at China's Tiangong Space Station continued to make steady progress over the past week with the three-membered crew in excellent health and a range of scientific experiments proceeding as planned, according to the China Manned Space Agency (CMSA).
Astronauts Chen Dong, Chen Zhongrui, and Wang Jie, sent into space on April 25, 2025, carried out a variety of medical tests and scientific experiments during the productive week, the agency said.
Using devices, such as vision measuring machines and eye trackers, and related software, they conducted tests for several projects, including trust and coordination mechanisms, the representation of visual and gravitational motion, metacognitive monitoring research, and relationship cognition in microgravity, providing data for further studies on the ground.
Additionally, the crew conducted vascular ultrasound examinations to obtain hemodynamic data for related studies of their impact at specific on-orbit times during their stay in space.
They also carried out memory, strength, and heavy object tests for studies on the changing patterns and cognitive mechanisms of fine motor control in microgravity environment.
The astronauts also advanced the research exploring the effect mechanisms of space microgravity on microorganisms through studies on streptomyces in the biotechnology experiment cabinet.
They collected liquid culture samples and froze them for storage and further investigation on the ground.
For physics experiments, the crew replaced the sample cover for experimental insertions into the combustion cabinet and cleaned the containerless material experiment rack.
Meanwhile, the crew underwent Chinese medical examinations, including 12-lead electrocardiograms (ECG) examinations, and dynamic ECG and blood pressure monitoring sessions over the past week.
They have conducted physical exercise and properly used instruments to counteract the physiological effects of weightlessness, according to the agency.
