CCTV.com News: Shenzhou 20 astronauts have been working and living in China's space station for more than a month. Since the first out-of-cabin event was successfully completed on May 22, the Shen Twenty Crew Group took a break and then entered a new round of intense and orderly on-site work. Last week, what were the daily "work list" of the three astronauts completed?
Last week, the crew carried out more than ten practical (trial) experimental research related work in space science.
In the field of aerospace medicine experiments, astronauts have collected and processed blood samples based on research on bone metabolism interaction regulation, aerospace integration omniscience, space rhythm and sleep. The downward samples help to study the changes in the bones, nerves and other related physiological systems of astronauts during long-term flights.
In the study of astronauts' psychological and behavioral abilities, the crew used a fine motion measuring instrument to carry out memory sliding tests. The test results were used to study the changes in astronauts' fine motion control and adaptive learning mechanisms.
In the research on human factors technology, a long-term study of kinematic characteristics of astronauts has been carried out. By analyzing the posture characteristics and laws of operation and movement in the astronauts' cabin, it provides data support for ergonomic design and evaluation, optimization of on-orbit mission planning and other work.
In the field of space life sciences, the crew completed the collection and storage of small controlled aquatic ecological life experimental units. This sample carried out spatial zebrafish adult experiments in a small controlled life ecology experiment module. By studying the effect of microgravity on the homeostasis of higher vertebrates, the regulatory effect of protein homeostasis on the decrease in bone mass and cardiovascular dysfunction caused by weight loss.
In the field of microgravity physical sciences, the crew carried out the replacement of the sample cover of the experimental plug-in of the combustion science experimental cabinet, the cleaning of the experimental cavity of the container-free experimental cabinet, the sample replacement, the maintenance of the axis mechanism, and carried out the replacement of the sample liquid bags of the "Space Three-Phase Multi-Drop Migration Behavior" of the fluid physical cabinet to explore the droplet thermal capillary migration movement in the microgravity environment.
In addition, the crew also completed the self-inspection work in the cabin of the space radiation biological exposure device.
Environmental monitoring and equipment maintenance in the space station are promoted in an orderly manner
Last week, the crew carried out environmental monitoring in the station, and maintained and tested some equipment, completing the maintenance of the regeneration and maintenance system, occupant equipment equipment, power-up test of humidity sensor spare parts, noise measurement and noise reduction status inspection in the cabin equipment.
The crew also conducted non-invasive cardiac function examinations, hearing tests and subjective questionnaire filling, overall visual function measurement, transorbital B-ultrasound measurement, bone density and muscle dimension measurement and other medical examinations to comprehensively monitor the on-orbit physical health.
