OA-7, previously known as Orbital-7, is the eighth flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its seventh flight to the International Space Station (ISS) under the Commercial Resupply Services contract with NASA.[5] The mission launched on 18 April 2017 at 15:11:26 UTC. Orbital 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.[9]
The Cygnus OA-7 is named the S.S. John Glenn in honor of astronaut and senator John Glenn, the first U.S. astronaut to orbit the Earth on Mercury-Atlas 6 and the oldest to go to space on STS-95, until 2021.[10]
