CCTV News: Shenzhou 19 astronaut crew has been working and living in orbit for more than 150 days.
After successfully completing the third out-of-cabin activity, the Shen 19th crew took a short rest and then actively participated in the subsequent on-site work. Last week, three astronauts continued to carry out space science experiments, experiments, emergency life-saving training and other work in an orderly manner to see their daily life in space.
Last week, the crew completed the equipment entry, sample recovery, assembly and testing and secondary outlet of components and components for general tests of external cabins. The parameters and on-orbit characteristic data obtained by this project will be combined with ground verification data for comprehensive analysis to evaluate its on-orbit application performance, and provide key data support for the research and development of components for high-performance space applications. In addition, astronauts carried out on-orbit test verification of space station pipeline detection robots as planned, realizing image detection in ventilation ducts, laying a technical foundation for automatic detection of space station pipelines. The experiment verified the robot mechanism design that is adapted to a variety of complex pipelines, as well as key technologies such as multi-level coordinated whole-body motion control of robots in complex pipeline environments. In the field of aerospace medicine experiments, the crew completed blood collection, centrifugation processing, cryopreservation and other operations. Ground researchers will use downward blood samples to carry out a number of experimental studies such as bone metabolism interactive regulation, aerospace integration omnisology, spatial rhythm and sleep. The crew carried out behavioral and eye movement experiments for the "Microgravity Relationship Cognition Project". By using eye movement instruments, laptops and other equipment, they recorded eye movement characteristics, obtained eye movement data, and studied human cognitive laws of relationships and their neural basis in spatial microgravity environment. In addition, the crew also completed a number of experimental operations in the field of microgravity physical science.
Last week, the astronaut completed the rapid on-and-off training for pressure suits in the cabin, improving operating proficiency in weightlessness. Relevant data also provide support for improving the emergency evacuation plan.
The crew efficiently completed the inspection and maintenance of equipment related to the regeneration and maintenance system, and carried out a series of medical examinations such as routine blood, blood biochemistry, quality measurement, intraocular pressure and fundus examination. At the same time, through on-orbit exercise combined with relevant instruments and equipment, the impact of fighting weightless environment on the human body was studied.
