The reporter learned from the China Manned Space Engineering Office that the crew of Shenzhou-19 successfully completed their first extravehicular activity on December 17th. At 21:57 on the same day, after 9 hours of extravehicular activity, astronauts Cai Xuzhe, Song Lingdong, and Wang Haoze of the Shenzhou-19 crew 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, inspecting and disposing of extravehicular equipment. Astronauts Cai Xuzhe and Song Lingdong have safely returned to the Wentian experimental module, and their extravehicular activities have been a complete success, once again breaking the record for the duration of extravehicular activities for Chinese astronauts. Astronaut Cai Xuzhe takes another spacewalk after two years, and Song Lingdong becomes China's first "post-90s" astronaut to conduct extravehicular activities. According to the plan, during the manned flight mission of Shenzhou-19, personnel and application payload extravehicular activities will be carried out, and a large number of scientific and technological experiments will be conducted. On December 17th, footage of Shenzhou-19 astronaut Cai Xuzhe working outside the space station module was taken at the Beijing Aerospace Flight Control Center. The footage of Shenzhou-19 astronaut Song Lingdong working outside the space station module was taken on December 17th at the Beijing Aerospace Flight Control Center.
