Hayley Arceneaux is a St. Jude Children’s Research Hospital physician assistant, a career she committed to at age ten, after surviving pediatric bone cancer. At age twenty-nine, she joined SpaceX’s first private spaceflight, Inspiration4, which launched on September 15, 2021, and successfully water-landed three days later, making her the youngest American to orbit the earth, the first pediatric cancer survivor in space, and the first astronaut with a prosthetic body part.
