CCTV news: At present, the three astronauts of the Shenzhou 21 crew have been working in orbit for more than 4 months. According to the China Manned Space Engineering Office, at 19:35 on March 16, the astronaut crew of Shenzhou 21 successfully completed the second extravehicular activity.

Attention to all accounts, I am from Beijing. Before opening the exit hatch, the status must be confirmed to be normal. Subsequently, the exit hatch will be opened as planned and the exit activities will begin.

After seven hours of extravehicular activities, the Shenzhou 21 crew astronauts Zhang Lu, Wu Fei, and Zhang Hongzhang worked closely together, and with the cooperation and support of the space station's robotic arm and ground scientific researchers, successfully completed the installation of space debris protection devices and other tasks. The extravehicular astronauts Zhang Lu and Wu Fei have safely returned to the Wentian experimental module, and the extravehicular activity was a complete success.

Shenzhou 21, close the exit door, completed.
