I hammered out this insignia for the December 2015 NASA Social event for the launch of the Cygnus OA-4 crew resupply mission. This would be an extended version of the Cygnus CRS payload and will be put into orbit with an Atlas V-401 and Centaur upper stage.
I ran through several iterations of the patch as I learned that the Cygnus for this mission would be the extended Cygnus Pressurized Cargo Module (PCM), so I had to correct the dimensions of the module. I also applied the wrong solar panels. This spacecraft would use the circular fanfold style as opposed to the folding rectangular type.
