The Boeing CST-100 was designed as part of NASA’s Commercial Crew Program. In September, 2014, Boeing was selected to manufacture the CST-100 as NASA’s human spacecraft provider.
The CST-100 is designed to transport up to seven passengers or a mix of crew and cargo to low-Earth orbit destinations such as the International Space Station (ISS) and the Bigelow planned station.
The CST-100 was designed at the Houston Product Support Center and will be manufactured at the Commercial Crew Processing Facility (C3PF), formerly Orbiter Processing Facility-3 (OPF3), at Kennedy Space Center in Florida. Boeing will immediately begin manufacturing three CST-100 structural test articles at the Commercial Crew Processing Facility pending NASA award. These test articles will be used in the pad abort test in 2017, first uncrewed flight in mid-2017, as well as the first crewed flight to the ISS in late-2017.
