CRS NG-13

Cygnus NG-13, previously known as CRS OA-13, is the fourteenth planned flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its thirteenth flight to the International Space Station under the Commercial Resupply Services contract with NASA. The mission is scheduled to launch on 9 February 2020. This is the second launch of Cygnus under the CRS2 contract.

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 System (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. Northrop Grumman purchased Orbital in June 2018; its ATK division was renamed Northrop Grumman Innovation Systems.
