A tech billionaire performed the first private spacewalk hundreds of miles above Earth on Thursday, a high-risk endeavor reserved for professional astronauts — until now.
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. Astronauts at the International Space Station often need to move across the sprawling complex for repairs, always traveling in pairs and lugging gear. Station spacewalks can last seven to eight hours; this one clocked in at less than two hours.
Isaacman emerged first, joining a small elite group of spacewalkers who until now had included only professional astronauts from a dozen countries.
周四，一位科技亿万富翁在距离地球数百英里的地方进行了首次私人太空行走，这是一项高风险的行动，只有专业宇航员才能进行——直到现在。
科技企业家贾里德·艾萨克曼与 SpaceX 合作，在他的包机上测试该公司的全新宇航服。在艾萨克曼安全返回后，SpaceX 工程师莎拉·吉利斯也参与了这项大胆的壮举。
与美国宇航局进行的冗长活动相比，这次太空行走简单快捷——舱门打开仅半小时。国际空间站的宇航员经常需要穿过庞大的综合设施进行维修，总是成对出行，拖着装备。空间站太空行走可持续七到八个小时；这次只持续了不到两个小时。
艾萨克曼首先出舱，成为一小群精英太空行走者，到目前为止，这个群体只有来自十几个国家的专业宇航员。
