Boeing’s Crew Space Transportation (CST)-100 is being developed as part of NASA’s Commercial Crew Program, which aims to resume U.S.-based flights to space by 2017.

The CST-100 will transport up to seven passengers or a mix of crew and cargo to the International Space Station (ISS) and other low-Earth orbit destinations.

Under the Commercial Crew Transportation (CCtCap) phase of the program, Boeing will build three CST-100s at the company’s Commercial Crew Processing Facility at Kennedy Space Center in Florida.

The spacecraft will undergo a pad-abort test in 2016, an uncrewed flight in early 2017, leading up to the first crewed flight to the ISS in mid-2017.
