Cygnus OA-7 Mission

Orbital ATK's seventh operational Cygnus cargo spacecraft, christened the S.S. John Glenn, delivered nearly three and a half metric tons of cargo to the International Space Station and is now set for its departure of the orbiting laboratory for a week-long free flight.

Being set free by the Station's robotic arm on Sunday, June 4, Cygnus will enter an independent orbit to complete an in-space fire experiment and deploy a group of four Lemur CubeSats before closing out its mission with a targeted, destructive re-entry.
