Which of these astronauts holds the U.S. record for spending the most total time in space?

下列哪名宇航员保持着美国在太空累计停留纪录？

Scott Kelly, Peggy Whitson, Neil Armstrong or Sally Ride?

斯科特·凯利、佩吉·惠特森、尼尔·阿姆斯特朗还是萨莉·赖德？

Scott Kelly had the longest single space flight, but Peggy Whitson has logged the most total time in space.

斯科特·凯利创下了最长的单次太空飞行记录，而佩吉·惠特森则刷新了累计在太空停留时间最长记录。

That total time being 665 days.

累计时间为665天。

Peggy Whitson held another record as well, the longest single space flight for a woman at 289 days.

佩吉·惠特森曾保持着另一项记录——以289天创下女性单次太空飞行最长记录。

But that record was just broken. Astronaut Christina Koch recently returned to earth from a mission that lasted 328 days. That's just 12 days short of Scott Kelly's single spaceflight record.

但这项记录刚刚被打破。最近，宇航员克里斯蒂娜·科赫在完成一项持续328天的任务后返回地球。这只比斯科特·凯利创下的单次太空飞行记录少12天。

During Koch's time on the International Space Station, NASA says she circled the Earth more than 5,200 times, traveled 139 million miles, carried out six spacewalks, and that included the historic ones she conducted with fellow astronaut Jessica Meir in October. The two of them completed the first all-female spacewalk.

美国国家航空航天局（简称NASA）表示，科赫在国际空间站期间，共绕地球轨道飞行了5200余次，绕行了1.39亿英里，完成了6次太空行走，其中包括她与同事杰西卡·梅尔在去年10月进行的那次历史性行走。这两名宇航员完成了首次“全女性”太空行走。
