Peggy Whitson holds the US record for most time in space, now, she's retiring.
As an astronaut, Whitson completed three long-duration missions to the International Space Station, setting records on each. In 2002, she become NASA's first Space Station science officer, and in 2008 become the first female commander of the Space Station.
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.
The space agency announced her retirement Friday, her last day on the job.
Peggy was born in OH and at the age of 26 became an employee of NASA. From, 2009 to 2012, she served as chief of the astronaut corps, becoming both the first female and the first non-military astronaut to hold the position.
She served in a number of scientific roles, including project scientist for the Shuttle-Mir Programme and co-chair of the US-Russian Mission Science Working Group, before her selection to the astronaut corps in 1996.

In this December 3, 2016 photo made available by NASA, astronaut Peggy Whitson poses for a photo in the cupola of the International Space Station, with the Earth in the background. Her last spaceflight was a year ago. Also her colleagues said that she showed the true spirit of American women and has always fulfilled all their duties objectively and efficiently. And, as of June 2018, she'd spent more time off the planet than any other American, with a total of 665 days over three missions. "Her determination, strength of mind, character, and dedication to science, exploration, and discovery are an inspiration to NASA and America".
She thanked "all who have supported me along the way".
The U.S. Postal Service honored the late Dr. Sally Ride with a "Forever" stamp. Artist Paul Salmon painted a portrait of Ride in her baby blue NASA uniform. "So not going into space with NASA anymore". It was also noted that the organization assumed incorrectly that the women wanted to wear makeup in space.
