IT Home, Nov 15: According to the 11th season of Tiangong TV released today on the official Weibo of the China Manned Space Engineering website, the fourth exposure experiment of the space radiation biology facility on China's space station is progressing smoothly, with experiment samples including nanozymes, actinomycetes and plant seeds returning to the cabin with the facility after completing five months of external exposure. The Shenzhou-23 crew completed sample retrieval, storage and facility disposal, and the samples will be used after their return to further study the deep effects of space radiation on organisms; the crew also carried out musculoskeletal loading research using plantar pressure collection equipment, collected and stored nasal swabs and environmental surface microbial swabs for research on virus-immune-metabolism interactions, and completed emergency decision-making capability assessments and in-orbit emotional state tests. In addition, the crew replaced experiment samples in the fluid cabinet and filters in the combustion cabinet, performed in-cabin environmental monitoring including total volatile organic compound and air cleanliness tests, replaced regenera

Shenzhou-23 Crew's "Space Business Trip" Enters Sixth Month; Samples Return to Cabin After 5 Months of External Exposure

IT之家 November 15 news: According to the content of "Tiangong TV" Season 11 released today on the official Weibo of the China Manned Space Engineering website, the fourth exposure experiment of the space radiation biology device on China's space station is progressing smoothly. Experimental samples including nanozymes, actinomycetes, and plant seeds completed a 5-month extravehicular exposure and returned to the cabin along with the device.

In the field of space life sciences and human research, the fourth exposure experiment of the space radiation biology device on China's space station is progressing smoothly. Experimental samples including nanozymes, actinomycetes, and plant seeds completed a five-month extravehicular exposure and returned to the cabin along with the device. The Shenzhou-23 crew completed the work of sample retrieval, storage, and device disposal. After these experimental samples are returned to Earth, they will be used for further research on the deep effects of space radiation on organisms.

Last week, the crew carried out research on musculoskeletal loading during exercise, using plantar pressure acquisition equipment to measure plantar pressure on a typical workday, and collecting relevant data for studying the characteristics of musculoskeletal loading under different in-orbit states.

IT之家 noted that the astronauts also carried out the collection, labeling, and storage of nasal swabs and environmental surface microbial swabs. The relevant samples will be used for research on the interaction between viruses and immune metabolism. The crew used computers and corresponding software to complete an emergency decision-making capability assessment and an in-orbit emotional state test. The test results will be used by ground personnel to analyze the patterns of change in the astronauts' emergency decision-making capability and emotional state during the mission.

In addition, the crew completed work including the replacement of experimental samples in the fluid cabinet and the replacement of filters in the combustion cabinet as planned, ensuring the smooth progress of related experiments in the field of space microgravity physical sciences.

In terms of care for the space station complex platform, the crew completed in-cabin environmental monitoring work such as total volatile organic compound testing and air cleanliness testing. They replaced equipment components of the regenerative life support system and the hot-air heating device of the space kitchen. At the same time, they carried out in-cabin environmental cleaning to continuously maintain the space station's livable environment.

In terms of health management, the three astronauts carried out exercise as planned and used weightlessness physiological effect protection equipment such as bone loss countermeasure devices to actively counteract the effects of weightlessness and maintain good in-orbit condition.
