Christopher Sembroski (born August 28, 1979) is an American data engineer, Air Force veteran, and spaceflight participant, currently living in Everett, Washington, United States. He was joined by billionaire Jared Isaacman on the Inspiration4 mission to orbit.

He is a Lockheed Martin employee and spaceflight participant for the Inspiration4 mission.[1] The spaceflight position was given to Sembroski after a friend had declined the prize, transferring it to Sembroski.[2] The friend, who knew Sembroski from Embry-Riddle Aeronautical University in Florida, remains anonymous. [3]

Sembroski has long had an interest in space, being an amateur astronomer and rocketeer.[4][2][5] Sembroski received the call sign "Hanks" during training.[6]

He is featured on the cover of a Time magazine double issue with the rest of the crew of Inspiration4 in August 2021.[7]


Sembroski grew up in Kannapolis, North Carolina.[1] During college, Sembroski volunteered for ProSpace, a nonprofit organization advocating for private spaceflight.[2] Sembroski also was a counselor at Space Camp in Huntsville, Alabama which promotes science, technology, engineering, and math to children and teenagers.[4][2] After college, Sembroski joined the United States Air Force as an Electro-Mechanical Technician stationed at Malmstrom Air Force Base in Great Falls, MT.[8] Sembroski now serves as a data engineer for Lockheed-Martin.[5]
