Peggy Whitson Shatters Barriers, Touches the Stars


The article features Peggy Whitson, an American astronaut who has spent more time in space than any other American. Whitson, a Rice distinguished alumna, served as the first female, nonmilitary Chief of the Astronaut Office for NASA and the first woman commander of the International Space Station (ISS). Despite her achievements, she credits her success to hard work and perseverance rather than extraordinary talent.

Whitson’s passion for space began at the age of nine, triggered by the Apollo 11 mission. She was initially discouraged by the absence of American women in space, but the 1978 selection of Sally Ride and Shannon Lucid as the first female and nonmilitary NASA astronauts gave her hope. After high school, she pursued a bachelor’s degree in biology and chemistry and a Ph.D. in biochemistry. Despite discouragement from advisors suggesting she go to medical school, Whitson remained steadfast in her aspiration to become an astronaut.

Despite facing numerous rejections, Whitson never gave up on her dream. She initially worked as a postdoctoral research fellow at NASA’s Johnson Space Center and took on several research and development projects. She also served as an adjunct professor at the University of Texas and at Rice and held leadership roles at the space center. After ten years and four rejection letters, she was finally accepted into NASA’s astronaut program in 1996.

Whitson’s first mission to the ISS took place in 2002, followed by her second trip in 2008 and a nine-month stay in 2016 marking her final voyage with NASA. During her time on the ISS, she and her crew were responsible for infrastructure assembly, space walks, and conducting scientific research.

Despite being barred from state-supervised spaceflight due to radiation limitations, Whitson found a way to return to zero gravity through private space infrastructure firm Axiom Space. Currently, as Axiom’s director of human spaceflight, she is helping to engineer future space suits and stations. Despite the challenges and obstacles she faced, Whitson’s story is a testament to the power of perseverance and dedication in achieving one’s goals.
