The Boeing CST-100 Starliner (Crew Space Transportation) crew capsule is a spacecraft design under construction by Boeing as their entry for NASA's Commercial Crew Development program. Its primary purpose is to transport crew to the International Space Station and to private space stations.
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.
Boeing as a space agency has recently provided NASA with assistance on sending humans to the ISS from American with both their construction of the CST-100 Starliner crew capsule and their work on the SLS Avionics to return to the moon and beyond. Their ventures in GPS satellite systems and Tracking and Data Relay Satellites provide information about earth-orbiting craft to stations on the ground. They also enable research on the ISS and will be helping with the construction of the Lunar Gateway.
