Having moved into China’s space home for nearly three months, the Shenzhou-14 crew smoothly conducted its first extravehicular(舱外的) activity on Thursday, the China Manned Space Agency (CMSA) said. The entire process took about six hours, and it was the first time that astronauts ventured out through the airlock cabin(气闸舱) in the Wentian lab module(舱), which just arrived at the space station about a month ago.
中国载人航天局称，Shenzhou-14机组人员进入中国航天家园近三个月后，于周四顺利进行了首次舱外活动。整个过程花了大约六个小时，这是宇航员第一次冒险穿过温田实验室模块的气闸舱，大约一个月前刚刚到达空间站。
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. They began preparing for their exit wearing spacesuits at 3:48 pm on Thursday, and at 7 pm, the two successfully moved out of the cabin. Together, Chen and Liu completed the installation of the extended pump set of the Wentian and the lifting of the panoramic(全景的) camera, as well as other tasks with the help of the small robotic arm.
Shenzhou-14的任务指挥官陈东和机组人员刘洋这次被指派进行太空行走任务，而他们的队友蔡旭哲负责机舱内的各种支援工作。他们开始准备在周四下午3:48穿着太空服离开，下午7点，两人成功地搬出了船舱。在小机械臂的帮助下，陈和刘一起完成了文田加长泵组的安装和全景摄像机的提升以及其他任务。
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(节点舱) for the astronauts’ exit in the Tianhe has a gate width of 85 centimeters, while the airlock cabin in the Wentian is one meter wide, allowing astronauts with space suits on and equipment in hand to walk more “freely” into space. Therefore, the airlock cabin of the Wentian will become the main exit-entry point for extravehicular activities, while the previous one in the Tianhe will serve as backup(备用物). The two exit-entry cabins will better ensure the safety of astronauts in case of an emergency during extravehicular work.
与以前Shenzhou-12 13号机组人员通过天河核心舱离开空间站的时候不同，该机组人员第一次冒险通过文田实验室模块的气闸舱，它于7月25日刚刚抵达空间站。天河宇航员出口的节点舱门宽85厘米，而文田的气闸舱宽1米厘米，允许穿着太空服和手头装备的宇航员更 “自由” 地进入太空。因此，文田的气闸舱将成为舱外活动的主要出入口点，而天河的前一个气闸舱将作为后援。两个出入境舱将更好地确保宇航员在舱外工作期间发生紧急情况时的安全。
