David Saint-Jacques’ First Spacewalk

加拿大航天局的大卫·圣雅克于2019年4月8日完成了他职业生涯中的第一次太空行走。在他的推特账号@Asrro_DavidS上，他写道:“这是多么美妙的景色啊。美妙到语言难以形容。

在长达6个半小时的太空行走中，他和美国国家航空航天局(NASA)宇航员安妮·麦克莱恩(Anne McClain)成功地为加拿大制造的机械臂Canadarm2建立了一条冗余电源通道，并安装了电缆，以便在轨道综合设施之外提供更广泛的无线通信覆盖，以及增强硬连线计算机网络的能力。两人还重新安置了第一次太空行走的适配器板，为未来的电池升级操作做准备。这是空间站近一个月来的第三次太空行走。

David Saint-Jacques of the Canadian Space Agency completed the first spacewalk of his career on Monday, April 8, 2019. On his Twitter account @Asrro_DavidS, he wrote: “What a view. Words are missing. // Quelle vue. Les mots me manquent. #DareToExplore #OsezExplorer”

During the six-and-a-half-hour spacewalk, he and NASA astronaut Anne McClain successfully established a redundant path of power to the Canadian-built robotic arm, known as Canadarm2, and installed cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability. The duo also relocated an adapter plate from the first spacewalk in preparation for future battery upgrade operations. This was the third spacewalk in just under a month on the space station.
