If you want to create a mesh for Pioneer P-30, this image might helpView attachment 22868
A rough facsimile of Pioneer P-30 in orbit around the Moon, September 1960.
It was the closest an Atlas Able ever came to succeeding, so I thought it would make an interesting "what if" scenario if the U.S. had managed to put something in lunar orbit 6 years before the U.S.S.R. would do with Luna 10. The spacecraft specs are correct down to the fuel, engine isp, weight, and thrust, but I used the generic Velcro Luna 3 mesh as a placeholder since I don't have a proper mesh for that series of Pioneer spacecraft. The transit time from launch to the Moon was ~64 hours. Insertion into a 6,800km x 7,000km orbit on 90 newtons of thrust takes nearly 22 minutes.
