Shenzhou 14 astronauts successfully completed EVA outside new cabin module.
Chen Dong and Liu Yang complete the 5th spacewalk for Tiangong Space Station
At 16:33 UTC on September 1, 2022, 00:33 Beijing time, after about 6 hours of outboard activities, Shenzhou 14 astronauts worked closely together to complete all the scheduled tasks during the outboard activities. He has returned to the Wentian experimental cabin safely, and the Extra Vehicular activity was a complete success.
The 5th Spacewalk of Tiangong Space Station began at 18:26 on September 1, 2022, Beijing time (12:26 UTC), Mission commander of Shenzhou-14 Chen Dong and crew member Liu Yang were assigned to conduct the spacewalk mission this time, while their teammate Cai Xuzhe was responsible for various support work inside the cabin,
Chen Dong donned the Feitian spacesuit and successfully opened the exit hatch of the Wentian experimental cabin airlock at 19:09 (13:09 UTC).
During the astronaut's Extra Vehicular activities, the station and earth cooperated closely, and the inside and outside of the cabin cooperated closely, and successively completed tasks such as the installation of the extended pump set in the Wentian cabin, the lifting of the panoramic camera in the Wentian cabin, and the autonomous emergency return verification outside the cabin. The whole process was smooth and successful.
The inspection and ability of the astronauts to work together with the small robotic arm have been verified, and the functional performance of the Wentian experimental cabin airlock and related support equipment for exit activities has been verified.
Unlike previous times when the Shenzhou-12 and 13 crews exited the space station through the Tianhe core cabin, the Shenzhou-14 crew for the first time ventured out through the airlock cabin in the Wentian lab module, which just arrived at the space station on July 25.
The node cabin for the astronauts' exit in the Tianhe has a hatch width of 85 centimeters, while the airlock cabin in the Wentian is one mete
