Cygnus NG-12

NG-12, previously known as OA-12, was the thirteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its twelfth Commercial Resupply Services flight to the International Space Station (ISS) for NASA. The mission launched on 2 November 2019 at 13:59:47 UTC). This was the first launch of Cygnus under the Commercial Resupply Services 2 (CRS-2) 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 Services (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 ATK in June 2018; its ATK division was renamed Northrop Grumman Innovation Systems.

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

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 at Dulles, Virginia and Houston, Texas. This is the ninth flight of the Enhanced-sized Cygnus PCM.

In 2019, the spacecraft was named the S.S. Alan Bean.

Total weight of cargo: 3,705 kg (8,168 lb), consisting of 3,705 kg (8,168 lb) in pressurized cargo and 119 kg (262 lb) in unpressurized cargo.

Among the cargo delivered was a special made oven for use in space, and some cookie dough. The crew of ISS 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.

Another research-related item delivered is the AstroRad radiation protective vest, which astronauts will wear to determine the degree of flexibility and freedom of movements experienced by them while working with these vests. This feedback will be used to possibly improve the comfort and ergonomics of the radiation vests if needed. AstroRad is useful in significantly reducing the short-term deterministic effects such as acute radiation syndrome and the probability of stochastic effects such as cancer in long-term ex-LEO missions.
