Boeing’s Orbital Flight Test-2 will be Starliner’s second uncrewed flight test and will dock to the International Space Station as part of NASA's Commercial Crew Program. The mission, currently targeted for launch on 6:54 p.m. ET on May 19, will serve as an end-to-end test of the system's capabilities. Photo Credit: (NASA/Joel Kowsky)

NASA astronaut Suni Williams, pilot for Boeing’s Crew Flight Test (CFT), checks her spacesuit during a crew validation test inside the Astronaut Crew Quarters at NASA’s Kennedy Space Center in Florida on Oct. 18, 2022. Williams, along with NASA astronauts Barry “Butch” Wilmore, CFT commander, and Mike Fincke, CFT backup spacecraft test pilot, with assistance from the Boeing team, successfully completed the validation test during which they suited up and tested out the pressurized crew module to ensure seat fit, suit functionality, cabin temperature, audio system, and day of launch operations. Boeing’s CFT is scheduled to launch in April 2023.
