Handout undated photo of Hayley Arceneaux, 29, who is the first bone cancer survivor to become an astronaut, the first person with a prosthetic body part to visit space and the youngest American ever to orbit Earth. In January, the physician assistant was picked to join the crew of the world's first all-civilian space mission. Her selection for the historic mission was announced on Monday by the St Jude Children's Research Hospital in Memphis, Tennessee, where Ms Arceneaux, now 29, was once a cancer patient as a child and now works.
