 Cygnus NG-19 mission patch | |
NG-19 was the nineteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its eighteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-2) contract with NASA. The mission launched on 2 August 2023 at 00:31:14 UTC.[1] This was the eighth launch of Cygnus under the CRS-2 contract.[2][3]
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.[4]
This flight used the last remaining Antares 200 series LV, which was constructed in Ukraine and uses Russian motors. The next three Cygnus missions will use Falcon 9, and subsequent mission will use the next-generation Antares 300 series that does not depend on Ukrainian or Russian parts.[5]
