The first astronaut cave training organized by China recently ended successfully in Wulong District of Chongqing. A total of 28 astronauts participated in this training. The one-month training was organized and carried out under the leadership of the China Astronaut Research and Training Center. The trained astronauts were divided into 4 groups and took turns staying continuously for 6 days and 5 nights in a cave with an average temperature of 8℃ and humidity of up to 99%. The cave environment is similar to extreme conditions in space, such as isolation, confinement, and high risk. During the training, astronauts completed scheduled tasks such as cave exploration, scientific research, material management, and livelihood security. They also had to experience extremely narrow passages, cliff climbing and rappelling, long-term humidity and cold stimulation, and extreme physical fitness tests, and overcome many challenges such as fear of darkness and sensory deprivation.
