Shenzhou 14 taikonauts Cai Xuzhe and Chen Dong successfully exited the airlock on the Wentian module on 17 September to work in the open cosmos. At 13:35 BJT, Cai opened the airlock hatch. By 15:33 BJT Cai and Chen were outside. Supported by the small mechanical arm, the pair conducted a series of tasks, including the installation of a foot-rest, 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. During the EVA, Liu Yang was inside the core module, supporting her crewmates. At 17:47 BJT, the 5-hour EVA was successfully completed.
