NG-12, previously known as OA-12, was the thirteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its twelfth Commercial Resupply Services flight to the International Space Station (ISS) for NASA.[5][6] The mission launched on 2 November 2019 at 13:59:47 UTC).[7] This was the first launch of Cygnus under the Commercial Resupply Services 2 (CRS-2) contract.[8]

Orbital ATK and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation Services (COTS) program, then Orbital Sciences designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft, and a Pressurized Cargo Module which is provided by Orbital's industrial partner Thales Alenia Space.[9] Northrop Grumman purchased Orbital ATK in June 2018; its ATK division was renamed Northrop Grumman Innovation Systems.[10]
