Soon-to-be youngest American in space shares how surviving cancer helped prepare her for mission

On "The View," Hayley Arceneaux discusses being a part of the first all-civilian crew to orbit Earth in SpaceX's upcoming Inspiration4 mission.

Hayley Arceneaux's dreams of becoming an astronaut were crushed after being diagnosed with pediatric bone cancer at 10 years old, but now she's set to go to space in the world's first all-civilian mission to orbit Earth. Now, the 29-year-old St. Jude Children's Research Hospital physician assistant is set to make history as the youngest American, first pediatric cancer survivor, and person with a prosthesis to go to space as one of the crew members in SpaceX's Inspiration4 mission. The four-person mission will launch in September in a SpaceX rocket commanded by entrepreneur and part-time pilot Jared Isaacman. Isaacman donated two seats to the hospital: One for Arceneaux and another that is being raffled to the public as part of a $200 million fundraiser for the hospital.
