The reporter learned from the China Manned Space Engineering Office that at 1:12 on January 21, after about 8.5 hours of extravehicular activity, the Shenzhou-19 crew members Cai Xuzhe, Song Lingdong, and Wang Haoze worked closely together, with the support of the space station's robotic arm and ground researchers, to complete tasks such as installing space debris protection devices and inspecting extravehicular equipment and facilities. Astronauts Cai Xuzhe and Song Lingdong have safely returned to the Wentian experimental module, and their extravehicular activities have been a complete success. The Shenzhou-19 manned spacecraft was successfully launched on October 30, 2024, and now the Shenzhou-19 crew's "space business trip" is about to pass halfway. It is reported that they will conduct a large number of scientific and technological experiments in orbit in the future, and will also celebrate the Chinese New Year of the Snake in a busy working state.
