From Rejection to Success: Dr. Peggy Whitson, America's Most Experienced Astronaut

Dr. Peggy Whitson, America's most experienced astronaut, was rejected four times before joining NASA's astronaut training program. Despite the setbacks, she went on to achieve numerous firsts in her 37-year aerospace career, including being the first female commander of the International Space Station. Dr. Whitson, who has spent a record-breaking 675 days in space, now serves as the director of human spaceflight at Axiom Space, where she aims to develop medical therapies using microgravity. She encourages the next generation of women in the field to challenge themselves and step outside their comfort zones.
