About two days after launch, the NG-18 Cygnus spacecraft is expected to be captured and berthed to the International Space Station.
Its final location will be the Earth-facing port of the Unity module. Aboard is expected to be some 3,500 kilograms of supplies for the Expedition 68 crew.
NG-18 Cygnus is slated to remain attached to the ISS for 1-2 months.
