China's Shenzhou-14 astronauts, or taikonauts, began their second extravehicular activities (EVAs) on Saturday, according to the China Manned Space Agency (CMS).Cai Xuzhe, the taikonaut who stayed inside the core module for support during the last EVAs, opened the airlock cabin of the Wentian lab module of the China Space Station at 1:35 p.m. Beijing Time. As of 3:33 p.m., Cai and Cheng Dong of the Shenzhou-14 crew successfully exited the cabin. At 5:47 p.m., the Shenzhou-14 crew successfully completed the second EVAs, which lasted about five hours, CMS announced.During the EVAs, the crew carried out operations including installing a foot-stop, which is used for fixing astronauts' feet on the robotic arm, and an assist handle, which can help astronauts open the hatch door from outside in an emergency.The taikonauts also installed additional pumps, the core equipment of the space station's thermal control system, and carried out the most challenging task of extravehicular rescue for the first time.
In task 3, astronaut CAI Xuzhe will be the one who "loses consciousness" and CHEN Dong will "rescue" him
