OA-5, previously known as Orbital-5, was the seventh planned flight of the Orbital Sciences' uncrewed resupply spacecraft Cygnus and its sixth flight to the International Space Station under the Commercial Resupply Services contract with NASA. The mission launched on 17 October 2016 at 23:45:36 UTC. Orbital Sciences 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 System (COTS) program, Orbital 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.
The Cygnus spacecraft for this mission is named the S.S. Alan Poindexter in honor to astronaut Alan G. Poindexter, a deceased Space Shuttle commander. Poindexter was selected in the 1998 NASA Group (G17) and went into orbit aboard Space Shuttle missions STS-122 and STS-131.
