Hayley Arceneaux (born 4 December 1991) is a St. Jude Children's Research Hospital physician assistant and commercial astronaut. She joined billionaire Jared Isaacman on SpaceX's first private spaceflight Inspiration4, which launched on 16 September 2021, 00:02:56 UTC, and successfully water-landed local-time at Saturday, 18 September 2021.[4] Arceneaux became the first astronaut with prosthetic leg bones after surviving bone cancer.[5] Arcenaux remained the youngest American astronaut to have traveled to space, having done so at the age of 29, until 11 December 2021, when Cameron Bess flew on Blue Origin's Blue Origin NS-19 at the age of 23.[6] Arceneaux remains the youngest American who has been in orbit.

Early life and education

Arceneaux was raised in St. Francisville, Louisiana. Her father, Howard Stanford Arceneaux, died July 5, 2018 at the age of 60 years old.[7] Her brother, Hayden, and sister-in-law, Liz Suttles, are aerospace engineers.[3]

When she was 10 years old,[8] her left knee began to ache. Her doctor thought it was just a sprain, but a few months later, tests revealed she suffered from osteosarcoma, a type of bone cancer. Her family turned to St. Jude Children’s Research Hospital for her treatment and care, which included around a dozen rounds of chemotherapy, a limb-preservation surgery with knee replacement and placement of a titanium rod in her left thigh bone along with associated physical therapy.[1] The experience inspired her to want to work with other cancer patients at St. Jude, which she does as a physician assistant working with leukemia and lymphoma patients.[8]

Arceneaux graduated from St. Joseph's Academy in Baton Rouge, Louisiana and obtained an undergraduate degree in Spanish in 2014. She obtained her Physician Assistant (PA) degree in 2016 from LSU Health in Shreveport, Louisiana.[8][9]

Personal endeavors

Inspiration4 spaceflight

Arceneaux was assigned to be the crew's chief medical officer. She has said she thinks she will be the first Cajun in space.[2] She is the first person to launch with a prosthesis.[1] As part of the training, she climbed Mount Rainier in Washington with the rest of the Inspiration4 crew.[10]

Arceneaux received the call sign "Nova" during training.[11]

Arceneaux is featured on the cover of a Time magazine double issue with the crew of Inspiration4 in August 2021.[12]
