Crew Space Transportation System

Boeing’s Crew Space Transportation (CST) system will provide NASA with transportation to and from the International Space Station.

A 21st Century Space Capsule

Boeing’s Crew Space Transportation (CST) -100 spacecraft was developed as part of NASA's Commercial Crew Program. The CST-100 can accommodate up to seven passengers, or a mix of crew and cargo to low-earth orbit destinations such as the International Space Station or the Bigelow planned station. The CST-100 capsule has an innovative, weld-less design and features Boeing LED “Sky Lighting,” wireless internet and tablet technology for crew interfaces.
