Contest-winning crew unveiled for all-civilian Inspiration4 spaceflight on a SpaceX rocket

A former Space Camp counselor and an “analog astronaut” whose father tracked Apollo science experiments deployed on the moon have won seats on board the first all-civilian spaceflight, joining a billionaire and a physician assistant who survived cancer as a child.

Chris Sembroski and Sian Proctor were revealed on Tuesday (March 30) as the winners of a sweepstakes and a competition, respectively, that were held to fill the final two seats on the Inspiration4 mission. The two will launch aboard a SpaceX Dragon capsule and orbit high above Earth together with Jared Isaacman, who is commanding and underwriting the cost of the mission, and Hayley Arceneaux, who was selected as an ambassador for St. Jude’s Children’s Research Hospital.

Slated to lift off as soon as mid-September, the Inspiration4 crew members will circle the planet for three days at an altitude about 80 miles (130 km) higher than the International Space Station. In the process, the four will set several records, both as individuals and together, including flying on the first space mission without a professional astronaut on board.

As first announced in February, Isaacman organized the Inspiration4 mission to not just fulfill his dream of flying in space, but “to send a message that inspiration can create a world of infinite possibilities up in the stars, but most importantly here on Earth.”

The sweepstakes won by Sembroski had the goal of raising up to $200 million for St. Jude’s efforts to save pediatric cancer patients worldwide. The contest brought in more than 72,000 donations, totaling $13 million, in addition to the $100 million pledged by Isaacman.

Sembroski was among those who donated to St. Jude’s, but it was a friend whose name was picked and who passed the winning ticket onto him for
