SpaceX Falcon 9 Launches Northrop Grumman's Cygnus Cargo Spacecraft To ISS

The Cygnus lifted off atop a Falcon 9 rocket from Cape Canaveral Space Force Station in Florida today at 1707 UTC. This is the 20th operational cargo mission for Cygnus, but the first time it's traveling atop a Falcon 9 rocket. SpaceX was not involved in the previous 19; as they all lifted off atop Antares or Atlas V rockets.
