From a working class background in Iowa in the United States, Peggy Whitson studied Biology and Chemistry at high school and went on to earn a degree in Biochemistry from one of America’s top universities. She became a medical science researcher at various universities, and eventually at NASA. Doing this research required Peggy to be very observant and also open-minded to new ideas.
Peggy joined NASA in 1989 and showed such commitment to her job that 7 years later she was selected as an astronaut candidate. She began the huge amount of training needed to go into space, with her first launch in 2002.
In 2007 she again visited the International Space Station (ISS), bringing her total time in orbit to 376 days. On October 28th 2016 she began her third voyage to the ISS, by the end of which she’ll have spent more time in space than any other US Astronaut, surpassing the previous record of 534 days. She’s also the first woman to command the ISS. Peggy is NASA’s most experienced female astronaut and, at 56, the oldest woman to go to space.
