John Young (NG-10) Cygnus mission came to an end today, Northrop Grumman Innovation Systems is readying the final elements for the next Cygnus mission, NG-11 – which is scheduled to launch No Earlier Than 17 April 2019 on a flight that will complete NGIS’s CRS1 commercial resupply services contract with NASA.
The NG-11 mission will also debut several new features/operations for Cygnus, some of which will fulfill NASA requirements for the upcoming six CRS2 contracted resupply missions.

Those were originally known as OA-8E, -9E, -10E and -11E, with the “E” signifying the “Extended” nature of missions in the CRS1 contract. When Northrop Grumman acquired Orbital ATK last year, the official mission designations ...
