Peggy Whitson is now the oldest woman to orbit Earth.
佩吉·惠特森现在是绕地球飞行的最年长者。
The 56-year-old NASA astronaut arrived at the International Space Station on Saturday.
这位56岁的美国宇航局宇航员于周六抵达国际空间站。
That just beats the previous record-holder, Barbara Morgan, who was 55 when she went to space.
这刚好击败以前的纪录保持者芭芭拉·摩根，她在55岁上太空。
This is far from Whitson's first record, though. She's on her third mission in space, having already become the ISS' first female commander and the only woman to ever lead NASA's astronaut corps.
这远不是惠特森的首个纪录。他是第三次执行太空任务，已成为国际空间站的首位女性指挥官，以及唯一领导美国宇航局宇航员队的女性。
She even holds the record for most time in space among female astronauts –– which actually made getting cleared this time more difficult, since NASA limits how much radiation astronauts are exposed to.
她甚至是在太空时间最长的女性宇航员，实际上使得这次更为艰难，因为美国宇航局限制宇航员暴露辐射的量。
By the end of her mission, Whitson should break another record: Most days spent in space by an American, regardless of gender.
任务结束后，惠特森要打破另一项记录：在太空时间最长的美国人，无论性别。
