NASA's Commercial Crew Program (CCP) was formed to facilitate the development of a U.S. commercial crew space transportation capability with the goal of achieving safe, reliable and cost-effective access to and from the International Space Station and low-Earth orbit.
The Dragon, CST-100 and the Dream Chaser are vehicles designed by commercial companies NASA chose to send astronauts up to the International Space Station.
