C3PO
Commercial Crew & Cargo Program
The C3PO will extend human presence in space by enabling an expanding and robust U.S. commercial space transportation industry.
COTS
Commercial Orbital Transportation Services
C3PO is responsible for managing NASA's Commercial Orbital Transportation Services (COTS) projects.
CCDev
Commercial Crew Development
Commercial Crew Development is a NASA investment that will aid in the development and demonstration of safe, reliable, and cost-effective space transportation capabilities.
Commercial Transportation
The Commercial Spaceflight theme encompasses completion of commercial cargo capability milestones and will expand NASA's efforts to develop commercial crew capability to LEO and the ISS.
Commercial Crew Program
NASA’s Commercial Crew Program (CCP) is an innovative partnership to help the United States industry develop space transportation systems that can safely launch astronauts to the International Space Station (ISS) and other low Earth orbit destinations.
ISS

| Sierra Nevada Corporation (SNC) is partnering with NASA to advance the development of a commercial crew space transportation system as part of the Commercial Crew Development (CCDev) program. The Dream Chaser is based on NASA’s HL-20 lifting body design and will be launched on the Atlas V launch vehicle. The Dream Chaser combines years of NASA analysis and wind tunnel research with Sierra Nevada’s engineering into a fully-reusable spacecraft to transport humans to low Earth orbit and then return them to Earth with a runway landing. A lifting body spacecraft design offers increased cross range and lower g forces on entry than a capsule design, providing more landing opportunities and a more benign entry environment for crew and science experiment return. | ||
