The number 7 cup was near vertical and cups 1 through 6 were facing 60 degrees from vertical. On Apollo 12 cup number 4 faced east and the point between cups 2 and 3 faced north. The Apollo 15 SWS was rotated 180 degrees from this configuration, so that cup number 1 was facing east and the point between cups 5 and 6 faced north. 2025-09-26 1.0 Creation.
