A crew transportation vehicle carrying NASA astronauts Suni Williams and Barry “Butch” Wilmore drives past the iconic Vehicle Assembly Building 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). The integrated exercise involved participation from the flight crew, NASA, Boeing, and United Launch Alliance (ULA), and 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.
