Cygnus NG-12, previously known as CRS OA-12, is the thirteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its twelfth flight to the International Space Station under the Commercial Resupply Services 2 contract with NASA.[5][6] The mission launched on 2 November 2019 at 9:59 AM (13:59 UTC).[1] This is the first launch of Cygnus under the CRS2 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 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.[8] Northrop Grumman purchased Orbital in June 2018; its ATK division was renamed Northrop Grumman Innovation Systems.[9]

History[edit]

Northrop Grumman launches the Cygnus NG-12 mission.

Cygnus NG-12 is the first mission under the Commercial Resupply Services 2 contract and launched 2 November 2019 at 13:59:47 UTC.[1]

Spacecraft[edit]

Production and integration of Cygnus spacecraft is 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 and Houston.[8] This is the eighth flight of the Enhanced-sized Cygnus PCM.[10]

Manifest[edit]

Total weight of cargo: 3,705 kg (8,168 lb), consisting of 3,586 kg (7,905 lb) in pressurized cargo and 119 kg (262 lb) in unpressurized cargo.[4]

  • Crew supplies: 680 kg (1,499 lb)
  • Science investigations: 1,983 kg (4,372 lb)
  • Spacewalk equipment: 104 kg (229 lb)
  • Vehicle hardware: 756 kg (1,667 lb)
  • Computer resources: 17 kg (37 lb)
  • Russian hardware: 11 kg (24 lb)
  • Northrop Grumman-related equipment: 35 kg (77 lb)

Among the cargo delivered was a special made oven for use in space, and some cookie dough. The crew of ISS will attempt to use the device to bake chocolate chip cookies in space (a first time for this kind of space activity). The baking of cookies in space attracted some international media attention when the mission was arriving at the space station.[2][11][12]
