NASA astronaut Barry “Butch” Wilmore emerges from the Neil Armstrong Operations and Checkout Building and prepares to enter a crew transportation vehicle at the agency’s Kennedy Space Center in Florida on Wednesday, Jan. 31, 2024, as part of an integrated crew exercise simulation for NASA’s Boeing Crew Flight Test (CFT). Wilmore and fellow crew member Suni Williams, along with NASA, Boeing, and United Launch Alliance (ULA), participated in the integrated exercise, which allowed teams to rehearse prelaunch operations beginning roughly four hours before a targeted liftoff. CFT will be the first flight with astronauts to the International Space Station for Boeing’s Starliner spacecraft as part of NASA’s Commercial Crew Program. Starliner is scheduled to launch atop ULA’s Atlas V rocket no earlier than mid-April 2024.
