CNN News:美国宇航员创女性单次太空飞行最长纪录 已返回地球

2020-03-11来源:和谐英语

Which of these astronauts holds the U.S. record for spending the most total time in space?
Scott Kelly, Peggy Whitson, Neil Armstrong or Sally Ride?
Scott Kelly had the longest single space flight, but Peggy Whitson has logged the most total time in space.
That total time being 665 days.
Peggy Whitson held another record as well, the longest single space flight for a woman at 289 days.

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.
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.
