This is the final flight of the Antares 200 series.
CRS-19
NG-19 is the nineteenth planned 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 is scheduled to launch on 2 August 2023. This is the eighth 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.
Cygnus NG-19 is the eighth 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.
The launch is scheduled for August 1, 2023, 8:31 p.m. EDT, / August 2, 00:31 UTC/GMT, and 02:31 CEST from LP-0A, NASA Wallops Flight Facility, Virginia, USA.
