Shenzhou XVIII Crew's Research and Missions in Space Station
TapTechNews August 11th news, since entering the space station on April 26th, the Shenzhou XVIII crew has been on orbit for more than 100 days. According to CCTV Network report, the Shenzhou XVIII crew is conducting research on The Impact of the Space Environment on Biological Rhythms and Sleep and Its Guidance.
As a research project in the field of aerospace medicine, this experiment focuses on the complex environmental factors of weightlessness and isolation-restriction in long-term flight. By having astronauts wear activity recording devices and heart rate collection equipment on orbit, filling out sleep quality questionnaires weekly, etc., to study human sleep-wake rhythms, heart rate rhythms, and changes in sleep quality under long-term flight conditions, providing basic data and theoretical support for the re-adaptation characteristics of the human physiological rhythm system during long-term flight and the screening of guidance and intervention targets. Currently, various scientific experiments and tests of the space application system are progressing in an orderly manner.
According to TapTechNews' previous report, the Shenzhou XVIII astronaut crew will stay at the space station for about 6 months (approximate 180 days). During on-orbit, they will carry out space science and application experiments, implement astronaut extravehicular activities and cargo in and out of the cabin, and conduct work such as the installation of space debris protection devices in the space station, the installation and recovery of extravehicular loads and extravehicular equipment. In addition, they will also carry out science popularization education and public welfare activities, as well as space-borne tests.
At 22:51 Beijing time on July 3, 2024, after about 6.5 hours of extravehicular activity, the Shenzhou XVIII crew astronauts Ye Guangfu, Li Cong, and Li Guangsu closely coordinated. With the cooperation and support of the space station's robotic arm and ground researchers, they installed a space debris protection device for the space station's external pipelines, cables, and key equipment, and completed the external inspection task. This is also the second extravehicular activity of the Shenzhou XVIII crew.
