The mission, dubbed NG-20, marks the first of three planned flights of Cygnus aboard a Falcon 9 rocket. Liftoff occurred at 12:07 p.m. EST (1707 UTC).

Disconnected from the International Space Station berthing port and then cast free by the robotic arm, the commercial Cygnus cargo craft flew away Friday after successfully restarting U.S. resupply service to the outpost.

Closing out 52 days at the International Space Station, an automated Northrop Grumman Cygnus cargo craft left the research outpost Sunday to climb into a higher orbit for deployment of six CubeSats and further engineering experiments, before de-orbiting over Pacific Ocean later this month.
