从这个世界之外竖起大拇指

In this image from July 2020, NASA spacewalkers (from left) Bob Behnken and Chris Cassidy give a thumbs up during a spacewalk to install hardware and upgrade International Space Station systems. They were photographed by the crew from inside the cupola, the orbiting lab’s “window to the world.”

Behnken arrived on the station as a member of the Demo-2 crew. The Demo-2 mission was the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. Cassidy is the Expedition 63 commander.

在这张2020年7月的照片中，美国宇航局的太空行走者（左起）鲍勃·本肯和克里斯·卡西迪在太空行走时竖起大拇指，准备安装硬件和升级国际空间站系统。这些照片是工作人员在环绕轨道实验室的世界之窗冲天炉内拍摄的。

本肯是作为Demo-2任务的一员抵达空间站的。Demo-2任务是由SpaceX载人龙飞船和猎鹰9号火箭的宇航员首次发射到国际空间站，这是该机构商业船员计划的一部分。卡西迪是第63号远征队的指挥官。
