Teams at the Wallops Flight Facility ready the second Antares 200 series launch vehicle at the Horizontal Processing Facility for liftoff with the Cygnus OA-8 cargo spacecraft headed to the International Space Station. Integration work on the rocket was followed by the installation of the Cygnus spacecraft and late cargo loading including powered polar freezers and late additions to the cargo manifest before the cargo compartment was sealed off for the rollout of the Antares rocket.
