SpaceAngelI don't understand why the Cygnus was not launched on the Antares rocket; thought all the bugs were resolved after the 2014 accident...
Robert PearlmanNASA opted for the use of the Atlas V to increase the payload capacity (Cygnus can carry more cargo on Atlas than it does Antares) and for schedule reasons (this flight was originally slated to launch last month, before an Antares rocket would be available.

With OA-8, Cygnus returns to flying on Antares out of the Wallops Flight Facility.
