Tech billionaire pulls off first private spacewalk high above Earth 美国亿万富豪实现人类首次商业太空行走 A tech billionaire popped out from a SpaceX capsule hundreds of miles above Earth and performed the first private spacewalk Thursday, a high-risk endeavor once reserved for professional astronauts. Tech entrepreneur Jared Isaacman teamed up with SpaceX to test the company’s brand new spacesuits on his chartered flight. The daring feat also saw SpaceX engineer Sarah Gillis going out once Isaacman was safely back inside. This spacewalk was simple and quick — the hatch was open barely a half hour — compared with the drawn-out affairs conducted by NASA. 周四，一位科技亿万富翁从距离地球数百英里的太空探索技术公司（SpaceX）太空舱中跳出，进行了首次商业太空行走，这是一项曾经只有专业宇航员才能进行的高风险活动。 科技企业家贾里德·艾萨克曼与SpaceX合作，在包下的飞船上测试该公司的全新宇航服。 艾萨克曼安全返回舱内后，SpaceX工程师莎拉·吉利斯也加入了这次壮举，进行了太空行走。 与美国国家航空航天局（NASA）进行的漫长的太空行走相比，这次太空行走简单而迅速——舱门只打开了半个小时。 ☞ pull off 成功完成：尽管困难重重，成功地完成某事。 If you pull off something very difficult, you succeed in achieving it. 做成 (某件难事) The National League for Democracy pulled off a landslide victory. 国家民主联盟取得了压倒性优势的胜利。 ☞ high above 高高在上：指某物或某人处于高处或高位，比如天空、山顶、建筑物顶部等。 ☞ pop out 击出：棒球：击出一个高飞球被接住算作出局。 ☞ endeavor 英 [ɪnˈdevə(r)] 美 [ɪnˈdevər] n. 努力；尽力（等于 endeavour） ☞ team up 美 [tiːm ʌp] 合作：与某人合作一起工作。 联合：与其他组织一起合作。 If you team up with someone, you join them in order to work together for a particular purpose.
