OA-9E was the tenth flight of the Cygnus, an uncrewed resupply spacecraft. The flight was launched by Orbital ATK (OA), which was purchased by Northrop Grumman during the mission. It was the ninth flight under the Commercial Resupply Services (CRS) contract with NASA and conducted under an extension, leading to the "E" in the mission name.[11][12] The mission launched on 21 May 2018 at 08:44:06 UTC.
Orbital and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station. 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.[13]
