NG-19 is the nineteenth planned flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its sixteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-2) contract with NASA. The mission is planned to launch in Autumn 2023.[1][2][3] This is the eighth launch of Cygnus under the CRS-2 contract.[4][5]

Orbital ATK (now Northrop Grumman Innovation Systems) 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, Orbital ATK designed, acquired, built, and assembled these components: Antares, a medium-class launch vehicle; Cygnus, an advanced spacecraft using a Pressurized Cargo Module (PCM) provided by industrial partner Thales Alenia Space and a Service Module based on the Orbital GEOStar satellite bus.[6]


Cygnus NG-19 is the eighth and potentially final Cygnus mission under the Commercial Resupply Services-2 contract. Northrop Grumman Innovation Systems confirmed on February 23, 2021 that Thales Alenia Space of Turin, Italy, will fabricate two additional Pressurized Cargo Modules (PCMs) for a pair of forthcoming Commercial Resupply Services-2 missions. Current plans are for the two additional Cygnus spacecraft to be designated NG-18 and NG-19.[2]

Production and integration of Cygnus spacecraft are performed in Dulles, Virginia. The Cygnus service module is mated with the pressurized cargo module at the launch site, and mission operations are conducted from control centers in Dulles, Virginia and Houston, Texas.[6]


This will be the fourteenth and potentially final flight of the Enhanced-sized Cygnus PCM[5][7] and of the Cygnus spacecraft as a whole.


Cygnus spacecraft is loaded with 0 kg (0 lb) of research, hardware, and crew supplies.[8]

  • Crew supplies: 0 kg (0 lb)
  • Science investigations: 0 kg (0 lb)
  • Spacewalk equipment: 0 kg (0 lb)
  • Vehicle hardware: 0 kg (0 lb)
  • Computer resources: 0 kg (0 lb)


The new experiments arriving at the orbiting laboratory will inspire future scientists and explorers, and provide valuable insight for researchers.
