Operational History
The design draws upon Boeing's experience with NASA's Apollo, Space Shuttle and ISS programs as well as the Orbital Express project sponsored by the Department of Defense. A variety of validation tests have been underway on test articles since 2011. The uncrewed orbital flight test launched on December 20, 2019, but after deployment, an 11-hour offset in the mission clock of Starliner caused the spacecraft to do a large engine burn, consumeing to much fuel, to reach the International Space Station, leading to an early return. A second uncrewed orbital flight test launched on May 19, 2022, which successfully reached the International Space Station.
