I am designing free return trajectory that connects Earth and Luna, and it's time to do b-plane targeting. I think that I have to change coordinate system that luna is in the center. Since I am using EarthMJ2000Eq coordinate system, I may be change it during flight. My plane is adjust orbit for b-plane targeting during moon transfer. How can I change coordinate system during a flight? My GMAT version is r2026a.

+Or please tell me how to use b-plane targeting that centers luna.
