IT Home reported on July 21 that according to CCTV.com, the Shenzhou 18 crew, which is on a business trip in space, has recently carried out tasks such as experimental sample replacement and full-system pressure emergency drills.

It is reported that in terms of space science experiments, in addition to completing a number of tasks such as replacing experimental samples in the containerless cabinet and fluid physics cabinet, the crew also replaced the filter window of the experimental plug-in in the combustion science experimental cabinet.The subsequent research will focus on the boiling heat transfer and enhancement mechanism.。

In addition, the crew carried out a study on "Recognition and Evaluation of Emotions of Astronauts on Space Station Missions". They used computers and corresponding test software to fill out questionnaires such as "Mood State" and "Positive and Negative Emotion State", and completed color preference tests and emotional picture tests. Ground researchers will use the results to evaluate the emotional state of astronauts on the space station mission.Assessing the emotional state of astronauts, in order to explore the changing patterns of astronauts' emotional state during my country's manned space station missions and explore the impact of medium- and long-term flights on them.

Last week, the Shenzhou-18 crew and ground researchers completed a full-system stress emergency drill.Simulating a collision with space debris on the space stationWhen faced with internal depressurization, the three astronauts carried out the entire process of emergency disposal. The drill began with a simulated depressurization alarm in the space station. The astronauts checked the alarm status and made judgments, looking for the location of the leak. The ground fully cooperated with the astronauts to plug the leak in orbit, and the ground and the earth cooperated to successfully complete the handling of the simulated emergency.

According to previous reports by IT Home, the Shenzhou 18 crew has conducted two extravehicular activities. The first was at 18:58 Beijing time on May 28, 2024, after about 8.5 hours of extravehicular activities.

The second time was at 22:51 Beijing time on July 3, 2024. After about 6.5 hours of extravehicular activities, the Shenzhou 18 crew astronauts Ye Guangfu, Li Cong, and Li Guangsu worked closely together, and with the cooperation and support of the space station's robotic arm and ground scientific researchers, installed space debris protection devices for the space station's extravehicular pipelines, cables and key equipment, and completed the extravehicular inspection mission.
