Chinese astronauts simulate a debris-strike emergency on the Tiangong space station (video)

Shenzhou 18 commander Ye Guangfu and crewmates Li Cong and Li Guangsu conducted the drill in mid-July to practice procedures for the case of a decompression event aboard the Tiangong space station.

The crew worked in collaboration with the ground team in Beijing, simulating the whole process of emergency response to a simulated scenario of space debris striking Tiangong and causing decompression.

After an alarm was raised, each crewmember quickly put on masks linked to air supplies. They then began to seek the source of the leak, successfully plugging it with the support of engineers back on Earth.

The Shenzhou 18 crew launched to Tiangong in late April. Combating the threat of space debris has been a key theme of the mission. The trio have so far embarked on a pair of spacewalks to install shielding to protect Tiangong from space debris and inspect the outside of the station.

The first of these extravehicular activities, in May, set a national spacewalk duration record of around 8.5 hours.

The Shenzhou 18 astronauts have also completed a range of other tasks, including replacing experimental samples and undergoing mental assessments.

The trio recently completed research for an “In-orbit Emotion Recognition and Evaluation of Astronauts,”  according to CCTV+. This involved questionnaires on emotional states and will be used to help researchers study and assess the impact of long-term space missions on astronauts’ mental health.

The Shenzhou 18 mission will last around six months. The crew will then welcome the Shenzhou 19 astronauts aboard Tiangong and hand over control of the station. China completed the three-module Tiangong space station in 2022 and aims to keep the orbital outpost permanently occupied for at least a decade.
