Orbital ATK and NASA jointly developed the Antares /Cygnus system to provide commercial resupply services to the orbiting laboratory. Orbital Sciences (the company's former name) designed and built Antares, a medium-class rocket. The Cygnus spacecraft is produced by Orbital's industrial partner Thales Alenia Space. This mission saw some 7,400 pounds (3,357 kilograms) of crew supplies, experiments and vehicle hardware sent to the ISS. Photos courtesy: Mike Deep, Mark Usciak, Charles Twine, Steve Hammer
