Shenzhou 20 astronaut crew has 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 the field of aerospace medicine experiments, focusing on the interaction regulation of bone metabolism, aerospace integration omniscience, space rhythm and sleep, astronauts collected and processed blood samples. The downward samples helped 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 mechanism.
In terms of human factor technology research has carried out long-term research on the kinematic characteristics of astronauts, and 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 samples 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 physics science, the crew carried out the replacement of the sample cover of the combustion science experimental cabinet experimental plug-in, the cleaning of the experimental chamber of the container-free experimental cabinet experimental chamber, sample replacement, axis mechanism maintenance, etc., and carried out the replacement of sample liquid bags for the "Space Three-Phase Multi-Drop Migration Behavior" of the fluid physical cabinet to explore the droplet thermal capillary migration movement in microgravity environment.
In addition, the crew also completed the self-test of the space radiation biology exposure device in the cabin --tt-darkmode-color: #B3B3B3;" class="data-color--tt-darkmode-b3b3b3">Related work.
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 inspected some equipment, completed the maintenance of the regeneration and reproduction 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.
Health maintenance and monitoring and guarantee of the Shen Twenty Crew Group uninterrupted
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 on-orbit physical health.
