NG-13, previously known as OA-13, was the fourteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its thirteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-1) contract with NASA.[4][5] The mission launched on 15 February 2020 at 20:21:01 UTC after nearly a week of delays.[6] This is the second launch of Cygnus under the CRS-2 contract.[7]

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, with Ukrainian specialists providing first stage structure.[8]

Cygnus, an advanced maneuvered spacecraft, mates a Pressurized Cargo Module, provided by Orbital's industrial partner Thales Alenia Space, with their GEOStar satellite bus.[9] Northrop Grumman purchased Orbital in June 2018; its ATK division was renamed Northrop Grumman Innovation Systems.[10]
