Peggy Whitson

Peggy Whitson, Ph.D., grew up on a farm outside of Beaconsfield, Iowa, with her siblings and parents, who were farmers. She decided to become an astronaut after she watched the first moon landing on television as a child in 1969.

As an astronaut, she flew on three NASA long-duration space flights and served as commander of Axiom Mission 2 (Ax-2), accumulating 675 days in space, more than any other American astronaut or woman astronaut in the world.

Whitson has more than 38 years of space and science experience combined with NASA and Axiom Space. Throughout her career, she has held various positions, including NASA’s Chief of the Astronaut Office, two-time Commander of the International Space Station (ISS), Chair of NASA’s Astronaut Selection Board, NASA Operations Branch Chief, NASA Deputy Division Chief for both Medical Sciences and the Astronaut Office, and co-chair of the US/Russian Mission Science Working Group.

During her three NASA missions to the ISS (Expeditions 5, 16 and 50/51/52), Whitson conducted 10 spacewalks – totaling more than 60 hours – and performed hundreds of research experiments.  On her first long-duration ISS mission on Expedition 5, she was named the first NASA science officer, conducting 21 investigations in human life sciences and microgravity sciences, as well as commercial payloads. Throughout her career she has contributed to hundreds of experiments in biology, biotechnology, physical and Earth science and welcomed several cargo spacecraft delivering tons of supplies and research experiments.
