NASA Cygnus NG-16 mission patch  

Cygnus NG-16, previously known as CRS OA-16, is the sixteenth planned flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its fifteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-2) contract with NASA. The mission is planned to launch on 1 August 2021 for a 56 day mission at ISS.[2] This is the fifth launch of Cygnus under the CRS-2 contract.[3][4]

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.[5]


Cygnus NG-16 is the fifth Cygnus mission under the Commercial Resupply Services-2 contract.

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.[5]


This will be the eleventh flight of the Enhanced-sized Cygnus PCM.[6][4]


Cygnus spacecraft is loaded with 0 kg (0 lb) of research, hardware, and crew supplies.[7]

  • 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)

SEOPS Slingshot Deployment System will deliver Cubesats to 500 km (310 mi) orbit, after un-berthing from ISS in late 2021.[8]


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