【ITBEAR】According to news on August 12, since entering the space station on April 26, the Shenzhou 18 crew has successfully been in orbit for more than 100 days and continues to carry out a number of scientific research and experimental tasks. According to CCTV, the crew is currently focusing on a research project called "The Impact of Space Environment on Biological Rhythm and Sleep and Its Guidance."

As a key research field in aerospace medicine, this research focuses on the impact of weightlessness and isolation-restriction composite environmental factors on the human body during long-term space flight. By wearing activity recording devices and heart rate collection equipment, and regularly filling out sleep quality questionnaires, astronauts systematically explore the changes in the human body's sleep-wake rhythm, heart rate rhythm, and sleep quality under long-term flight conditions, aiming to provide The re-adaptation characteristics of the human circadian rhythm system during long-term space flight and its guidance intervention strategies provide scientific basis and theoretical support. At present, various scientific experiments and tests of the space application system are proceeding steadily as planned. According to ITBEAR’s understanding, the Shenzhou 18 astronaut crew plans to stay on the space station for about 6 months. During this period, they not only have to carry out a series of space science and application experiments, but also perform astronaut extravehicular activities, cargo entry and exit tasks, install space debris protection devices on the space station, and deploy and recover extravehicular loads and equipment. In addition, the crew will also actively participate in popular science education and public welfare activities, as well as conduct space launch experiments to demonstrate the multiple values ​​of space exploration in many aspects.

It is worth mentioning that at 22:51 on July 3, 2024, Beijing time, the Shenzhou 18 crew astronauts Ye Guangfu, Li Cong, and Li Guangsu worked collaboratively. With the support of the space station’s robotic arm and ground scientific research team, After about 6.5 hours of extravehicular activities, space debris protection devices were successfully installed on important pipes, cables and key equipment outside the space station, and the extravehicular inspection mission was successfully completed. This is also the second extravehicular activity performed by the crew of Shenzhou 18, marking another important progress in my country's space station maintenance and scientific research tasks. -->
