Meet the Crew

Three people will travel with Jared Isaacman on the Inspiration4 mission. Find out below who they are and what they hope to achieve.

Sian Proctor

Sian Proctor, 51, is a professor of geosciences at South Mountain Community College, in Phoenix, Arizona. She was born in Guam. Her father was an engineer. He worked for NASA in Guam during the Apollo 11 mission. That mission resulted in the first moon landing, in 1969. Proctor has a note that the Apollo 11 commander, Neil Armstrong, wrote to her dad: “To Ed—Thanks for the help.”

Proctor is the mission pilot on Inspiration4. She steps in when Isaacman is not at the controls. Her father died in 1989. To thank him, Proctor will take the note from Armstrong with her on the trip.

Chris Sembroski

Chris Sembroski, 41, lives in Everett, Washington. He works for the aerospace company Lockheed Martin.

On Inspiration4, Sembroski is the payload specialist. He oversees cargo and repairs. Isaacman asked him to join the mission. Sembroski had made a donation to St. Jude Children’s Research Hospital and entered the mission lottery. After Isaacman’s call, Sembroski turned to his wife. “I think we’re gonna go ride a rocket,” he said.

Hayley Arceneaux

When Hayley Arceneaux was 10, she learned she had bone cancer in her left leg. She was treated at St. Jude and now has an artificial knee and a prosthetic × prosthetic FILIPPO ROMEO/EYEEM—GETTY IMAGES having to do with artificial body part (adjective) Because he had a prosthetic leg, he was still able to compete. bone in place of her femur × femur GEBER86—GETTY IMAGES the leg bone that goes from the hip to the knee (noun) A doctor tended to Max's broken femur. . Now she’s 29 and a physician assistant at St. Jude.

Arceneaux is the first person with a prosthesis to fly to space. If all goes well, she could change the standards used to judge astronauts. “A girl at the hospital told me that she can’t run or jump,” Arceneaux says. “I told her, ‘I can’t run or jump either. But that’s not stopping me from going to space.’”
