Here is my Munar orbiter candidate... KSP R&D haven\'t figured out a nice way to land yet, so I ain\'t trying yet. (Plus, I like to keep a vanilla build.) Behold, the Deimos II: Take off: After initial launch stage separation: Separation of second portion of initial launch, commencing orbiting procedure: Finishing orbit: Commencing burn to Munar orbit: Munar orbiter stage seperates: At this altitude, the orbiter will position itself in a orbit around the moon. (Projected to take 0.25-0.5 tank of fuel.) Munar returns to Kearth orbit: (Projected 0.35-0.75 tank of fuel.) Return to an orbit around Kearth: Plot reentry around the KSP center: (The whole rentry orbit and burn-out took only 0.5-0.6 of a tank.) Landing pod seperation: Final stats: Actually landed in the lake behind the center. Near the center of the picture.
