Cygnus (spacecraft)

The Cygnus spacecraft is an American automated cargo spacecraft developed by Orbital ATK as part of NASA's Commercial Orbital Transportation Services (COTS) developmental program. It is launched by Orbital's Antares rocket or Atlas V and is designed to transport supplies to the International Space Station (ISS) following the retirement of the American Space Shuttle. Since August 2000 ISS resupply missions have been regularly flown by Russian Progress (spacecraft), as well as by the European Automated Transfer Vehicle, and the Japanese H-II Transfer Vehicle. With the Cygnus spacecraft and the SpaceX Dragon, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry.
