19 年前的今天，Scott Parazynski 在 STS-120 任务中完成史上最惊险的太空行走之一：他搭乘国际空间站 Canadarm2 机械臂与航天飞机检查吊臂（OBSS）抵达受损的 P6 4B 太阳能翼，剪断卡住的导向索，并安装乘组自制的五个“袖扣”支架。Douglas Wheelock 在桁架上监视间隙。7 小时 19 分钟后，太阳能翼完全展开，空间站组装重回正轨。
Memories of an amazing spacewalk.
19 years ago today, Scott Parazynski carried out one of the most daring spacewalks in history. During STS-120, he rode the ISS's Canadarm2 (SSRMS) and the Shuttle's inspection boom (OBSS) out to the torn P6 4B solar array.
With Douglas Wheelock watching his clearances from the truss, Parazynski cut a snagged guide wire and fitted five homemade "cufflink" braces put together by the crew on board.
Seven hours and 19 minutes later, the array was fully deployed, and station assembly was back on track. 🫡
