Peggy Annette Whitson (born February 9, 1960) is an American biochemistry researcher, and astronaut working for Axiom Space. She retired from NASA in 2018, after serving as Chief Astronaut.[3] Over all her missions, Whitson has a total of 665 days in space, more than any other American or woman.[4][5]
Her first NASA space mission was in 2002: an extended stay aboard the International Space Station (ISS) as a crew member of Expedition 5. On her second mission, Expedition 16 in 2007-2008, she became the first woman to command the ISS.[6][7] In 2009, she became the first woman to serve as NASA's Chief Astronaut, the most senior position in the NASA Astronaut Corps.[8] In 2017, Whitson became the first woman to command the International Space Station twice. Her 289-day flight was the longest single space flight by a woman[9][10] until Christina Koch's 328-day flight.[11]
Whitson holds the records for the oldest woman spacewalker and the most spacewalks by a woman.[12][13] Whitson's cumulative EVA time is 60 hours, 21 minutes, which places her in fifth place for total EVA time.[1] At age 57 on her final NASA flight, she was the oldest woman ever in space at that time - a record broken in a 2021 sub-orbital flight by Wally Funk. She is still the oldest woman to orbit the Earth, a record she broke in 2023, at 63.[14]
On June 15, 2018, Whitson retired from NASA. She later became a consultant for Axiom Space[15] and is the commander of Axiom Mission 2[16] and will be the commander of Axiom Mission 4
Whitson was included in Time magazine's 100 Most Influential People of 2018.[17]
