The Boeing CST-100 Starliner (Crew Space Transportation) is a crew capsule manufactured by Boeing as its participation in NASA’s Commercial Crew Development (CCDev) program. Its primary purpose is to transport crew to the International Space Station (ISS) and to private space stations such as the proposed Bigelow Aerospace Commercial Space Station.
The capsule has a diameter of 4.56 meters (15.0 ft), which is slightly larger than the Apollo command module and smaller than the Orion capsule. The Starliner is to support larger crews of up to seven people and is being designed to be able to remain in-orbit for up to seven months with reusability of up to ten missions. It is designed to be compatible with four launch vehicles: Atlas V, Delta IV, Falcon 9, and Vulcan.
In the first phase of its CCDev program NASA awarded Boeing US$18 million in 2010 for preliminary development of the spacecraft. In the second phase Boeing was awarded a $93 million contract in 2011 for further spacecraft development. On August 3, 2012, NASA announced the award of $460 million to Boeing to continue work on the CST-100 under the Commercial Crew Integrated Capability (CCiCap) Program. On September ...
