An anonymous reader quotes UPI:
After nearly four decades with NASA, including 22 years as an astronaut, Peggy Whitson is leaving the space agency. Her retirement is effective Friday, NASA announced… Whitson ends her career with multiple records to her name, including most time spent in space by a U.S. astronaut — 665 days…
The 57-year-old Whitson was a scientist before she was an astronaut, earning graduate degrees in biochemistry from Rice University in Houston before coming to conduct research at NASA’s Johnson Space Center in 1989. The NASA scientist began training as an astronaut in 1996. She made her first trip to the International Space Station in 2008. During her time in space, including three long-duration stints aboard International Space Station, she helped carry out 21 science investigation and became the agency’s first space station science officer… Whitson took a second turn as commander during Expedition 51, part of her most recent — and last — stay on the space station, which spanned from November 2016 to September 2017.
