Shenzhou-20 Crew: Experiments & Equipment Maintenance | China Space Station
The Shenzhou-20 crew aboard China's Tiangong Space Station have continued to carry out a variety of tasks over the past week, proceeding with experiments in aerospace medicine, smart robots and microgravity, and completing maintenance on multiple devices.
The three astronauts—Chen Dong, Chen Zhongrui, and Wang Jie—smoothly advanced aerospace medical experiments including research on the upper and lower visual fields.
The crew completed behavioral tests using relevant equipment and software. The obtained data will be used to explore the influence of the microgravity environment, and the changes in the focus of attention on the asymmetry of astronauts' upper and lower visual fields and the related neural mechanisms, providing a reference for the subsequent mission procedures and human-computer interaction design.
The crew utilized a Raman spectrometer to conduct experiments on microbiota and nutrition metabolism. By detecting the metabolic components in urine samples, they further revised and improved the relevant characteristic metabolite index system and assessment criteria. These samples will be used in experiments investigating interactive regulation of bone metabolism and other studies on the earth.
Meanwhile, tests on the collaboration between astronauts and China's first intelligent spaceflight robot, Xiao Hang, were also ongoing to explore efficient collaboration methods through experiments on human-robot spatial relationships, robot behavior representation, and multimodal interaction technologies.
In addition, research related to microgravity combustion science continued.
The crew also completed as planned the in-depth maintenance of the microgravity resistance training equipment, the inspection and maintenance of the regenerative life support system equipment, the maintenance of the thermal control equipment, and the replacement of circulation pumps of fluid loop system for space applications.
Meanwhile, the three astronauts counted, confirmed, sorted and transferred the supplies, and cleaned the station regularly.
