Bio
Hines studied aerospace engineering and became an Air Force test pilot before NASA selection. His pre-astronaut career included flight-test work and technical aviation assignments that matched the modern spacecraft-operations track.
He launched on SpaceX Crew-4 in 2022 and served aboard the International Space Station during 67 and 68. The mission supported station research, maintenance, visiting vehicle operations, and the routine rotation pattern.
Hines is also listed in local profile data as the backup astronaut for Artemis III. That assignment connects his ISS experience with NASA's return-to-the-Moon planning, though Artemis crew assignments can evolve.
