Christopher Sembroski

Chris "Hanks" Sembroski represented the pillar of Generosity as part of the crew of SpaceX Inspiration4 by serving as Mission Specialist on a 3-day mission experiencing 47 orbits. This spaceflight brought awareness and support to St. Jude Children’s Research Hospital and successfully raised over $240 million dollars toward their lifesaving mission.

As a college student at Embry-Riddle Aeronautical University, Chris volunteered with ProSpace, a grassroots lobbying effort that promoted legislation in Washington, D.C., to help open up space travel and allow companies like Blue Origin and SpaceX to exist. He then served in the

U.S. Air Force, maintaining a fleet of Minuteman III intercontinental ballistic missiles and deploying for service in Iraq before leaving active duty in 2007.

Chris now works as an Avionics Testing Engineer for Blue Origin's New Glenn program. This reusable rocket stands over 310 feet (95 meters) tall, making it nearly the size of the Apollo program's Saturn V vehicle. He resides in Gig Harbor, WA, with his wife, two talented young daughters, and their two dachshund pups.
