Hayley Arceneaux

Hayley Arceneaux (born December 4, 1991) is an American physician assistant and commercial astronaut. She joined billionaire Jared Isaacman on SpaceX's first private spaceflight Inspiration4, which launched on September 16, 2021, 00:02:56 UTC, and successfully water-landed local-time on Saturday, September 18. Arceneaux became the first human in space with a prosthetic leg bone after surviving bone cancer. At age 29, Arceneaux was the youngest American to travel to space, surpassed a few months later by 23-year-old Cameron Bess aboard Blue Origin NS-19. As Bess' flight was suborbital, Arceneaux remained the youngest American to have orbited Earth.
