A NASA logo as a decal, make it simple , just a blue circle with a red line through it will do, don't make it have over 30 parts and make it in 2 sizes, 2x2 and 1x1 ( if 1x1 is impossible then it's okay, just make the 2x2 ) and put the decal on a 2x2 ultra thin fuselage for the 2x2 decal, and a ultra thin 1x1 fuselage for the 1x1 decal.
