The Shenzhou-18 crew from China successfully executed their first spacewalk in July and, more recently, engaged in a series of examinations and maintenance activities on the Tiangong space station. They also participated in a comprehensive emergency drill to prepare for potential internal pressure loss, which could occur due to impacts from space debris, as reported by China Central Television (CCTV).

During the emergency drill, the crew worked closely with ground control to simulate a scenario where a pressure loss alarm was triggered. The taikonauts assessed the alarm's status, identified the locations of potential leaks, and coordinated with ground teams to seal these leaks successfully. Before commencing the drill, the crew had confirmed their equipment and completed necessary preparations such as studying manuals and gathering items.

Wang Ya'nan, the chief editor of Aerospace Knowledge magazine, noted that impacts from space debris could vary in severity. Smaller debris might cause only minor issues that could affect external equipment, whereas larger pieces, measuring millimeters to centimeters, pose a significant risk as they could breach the station's hull. While the possibility of Tiangong being hit by debris exists, it is considered unlikely. Nevertheless, precautions are essential to ensure the safety of the taikonauts, with emergency drills focusing on assessing potential damage and taking steps to seal off compromised sections if necessary.

In urgent situations, the taikonauts may need to evacuate to safe compartments, take refuge in a docked spacecraft, or even make an emergency return. Observers express confidence in China's ability to manage such situations, noting that the space station is designed to withstand external impacts effectively. Monitoring large debris trajectories through international collaboration allows for proactive measures, such as altering the station's orbit to prevent collisions.

Lin Xiqiang, spokesperson for the China Manned Space Agency, indicated that addressing space debris protection would be a priority during Shenzhou-18’s mission. The crew has previously noted damage to solar panel cables from debris, leading to power supply issues. To enhance protection against space debris, the Shenzhou-18 team is installing reinforcements on external equipment and conducting necessary inspections.

Aside from the emergency preparedness activities, the crew has been involved in research on emotional recognition and evaluation while in orbit. They utilized software to assess their mood, preferences, and emotional states, which will help researchers understand the psychological effects of long-term space missions on the taikonauts.
