KCCI: NASA’s record-breaking astronaut, Peggy Whitson, is retiring. The space agency announced her retirement recently. Whitson, who grew up in Beaconsfield, a small town in southern Iowa, has spent more time off the planet than any other American: 665 days over three missions. She was the first woman to command the International Space Station, holding the position twice, and the oldest woman to fly in space. She was also the world’s most experienced female spacewalker, the first woman to serve as NASA’s chief astronaut, and recently was named a 2018 inductee into the Iowa Women’s Hall of Fame.
