NG-16,[1] previously known as OA-16, was the sixteenth 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 was launched on 10 August 2021 at 22:01:05 UTC, for a (planned) 90-day mission at the ISS.[2] This was the fifth launch of Cygnus under the CRS-2 contract.
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.
NG-16 was 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.
See main article: Cygnus (spacecraft). This was the eleventh flight of the Enhanced Cygnus. Northrop Grumman named this spacecraft after Ellison Onizuka, the first Asian American astronaut.
The Cygnus spacecraft was loaded with of research, hardware, and crew supplies.[3] [4]
The SEOPS Slingshot Deployment System delivered CubeSats to a orbit, following un-berthing from the ISS in late 2021.
The 4-Bed Carbon Dioxide Scrubber, a next-generation air filtration unit developed and built by NASA's Marshall Space Flight Center, was aboard Cygnus NG-16.

On 18 November 2021, SPDM/Dextre grappled STP-H6 from ExPRESS-3 and mounted it onto the external payload attach device on the hull.[7] At 16:01UTC on 20 November 2021, flight controllers on the ground sent commands to release the Northrop Grumman Cygnus spacecraft from the Canadarm2 robotic arm after earlier detaching Cygnus NG-16 from the Earth-facing port of the Unity module. At the time of release, the station was flying about over the South Pacific Ocean. The Cygnus spacecraft successfully departed the International Space Station more than three months after arriving at the space station to deliver about of scientific investigations and supplies to the orbiting laboratory. After departure, the Kentucky Re-Entry Probe Experiment (KREPE) stowed inside Cygnus took measurements to demonstrate a thermal protection system for spacecraft and their contents during re-entry in Earth's atmosphere, which can be difficult to replicate in ground simulations. Cygnus deorbited on 15 December 2021, following a deorbit engine firing to set up a destructive re-entry in which the spacecraft, filled with waste the space station crew packed in the spacecraft, burns up in the atmosphere of Earth.[8]
