The disposable Cygnus spacecraft and Antares rockets have been flying to the space station since 2013 NASA initially selected Orbital Sciences (later known as Orbital ATK and now as Northrop Grumman Innovation Systems) as one of two commercial cargo partners in 2008. SpaceX was the other company.
In 2016, NASA picked Northrop Grumman (then Orbital ATK), SpaceX and Sierra Nevada Space Systems, which is Dream Chaser for its cargo flights. To date, only Cygnus and SpaceX's Dragon cargo ships have flown resupply flights for NASA's commercial cargo program.
The International Space Station is currently stocked with a fleet of robotic cargo ships. In addition to Cygnus and Dragon vehicles, Russia's Progress Vehicles and Japan's H-II Transfer Vehicles are delivered. The European Space Agency flew five cargo missions with its own Automated Transfer Vehicle.
