FSOM
Final Stage Orbital Maneuver Engine
Mounts between payload and the KOEING SLS2 third stage — adds a high-impulse injection burn that extends the delivery envelope to destinations the SLS2 cannot reach unassisted. No new vehicle required. Two launches, two successes: POTHOLE module to LSI 1, and FARVIEW-1 solar orbit insertion. KerbalX compatibility: none planned, none needed.
