\nThe Common Core Booster first stage of the Atlas 5 rocket separates from the Centaur upper stage. Over the next few seconds, the Centaur engine liquid hydrogen and liquid oxygen systems are readied for ignition.<\/p>\n

\nThe Centaur RL10 engine ignites for the only upper stage firing of the mission. This burn will inject the Centaur stage and Cygnus spacecraft into low-Earth orbit.<\/p>\n

\nThe Orbital ATK Cygnus cargo delivery spacecraft for the International Space Station is released into orbit from the Centaur upper stage to complete the AV-064 launch. (Centaur will be deorbited shortly thereafter).<\/p>\n
