Peggy Annette Whitson (born February 9, 1960) is an American biochemistry researcher, and astronaut working for Axiom Space.
[17] Whitson grew up on a farm outside the town of Beaconsfield, Iowa, with her sister, Kathy, her brothers, Brian and Hugh, and her parents, Keith and Beth.
[19] Whitson graduated from Mount Ayr Community High School in 1978 and received a Bachelor of Science degree in biology and chemistry from Iowa Wesleyan College in 1981.
From April 1988 until September 1989, Whitson served as the Supervisor for the Biochemistry Research Group at KRUG International, a medical sciences contractor at NASA-JSC.
In 1997, Whitson began teaching as adjunct assistant professor at Rice University in the Maybee Laboratory for Biochemical and Genetic Engineering.
From 1991 through 1992, she was the payload element developer for Bone Cell Research Experiment (E10) aboard SL-J (STS-47), and was a member of the US-USSR Joint Working Group in Space Medicine and Biology.
Upon completing the two years of training and evaluation, she was assigned technical duties in the Astronaut Office Operations Planning Branch, and served as the lead for the Crew Test Support Team in Russia from 1998 to 1999.
Whitson was appointed NASA Chief of the Astronaut Office in October 2009, replacing Steven W. Lindsey.
During her six-month stay aboard the Space Station, Whitson installed the Mobile Base System, the S1 truss segment, and the P1 truss segment using the space station remote manipulator system; performed a 4-hour and 25 minute spacewalk in a Russian Orlan space suit to install micrometeoroid shielding on the Zvezda Service Module; and activated and checked out the Microgravity Sciences Glovebox, a facility class payload rack.
[28][29][30] Along with her Expedition 16 crew member Yuri Malenchenko and spaceflight participant Yi So-yeon, she returned to Earth in Soyuz TMA-11 on April 19, 2008.
The re-entry was remarkable for the failure of the Soyuz propulsion module to separate properly, and the subsequent "ballistic reentry" which subjected the crew to forces about eight times that of Earth surface gravity.
On September 3, she returned in a previously vacant seat on the Soyuz capsule accompanied by NASA's Jack Fischer and Fyodor Yurchikhin of Roscosmos.
During the EVA, they installed three new adapter plates and hooked up electrical connectors preparing the way to replace the ISS batteries.
On April 24, 2017, Whitson officially broke the record for longest amount of time spent in space by any NASA astronaut.
After a short delay due to leaking equipment, they replaced an avionics box on the starboard truss called an ExPRESS Logistics Carrier (ELC), a storage platform.
[49] In June 2020, Whitson was a guest (along with two imposters) on an ABC-TV To Tell the Truth episode in which Patti LaBelle correctly selected her as the record-holding time in space astronaut.
Axiom 2 lifted off on 21 May 2023 from Launch Complex 39A at Kennedy Space Center, onboard a Falcon 9 Block 5 rocket.
During the mission, the crew performed public outreach activities along with scientific research, including studies into the effects of microgravity on stem cells and other biological experiments.
