The Importance of Observation on the Moon

At first Ingo thought he saw patterns on the surface of the moon that he compared to tractor tread marks. When they went to the next set of coordinates, Ingo was puzzled because the impressions he was getting were even more unexpected for the lunar surface. He then perceived where the light was coming from. Two sets of lights high up off the ground, which he compared to the lights you'd find in football fields. They were giving off a greenish light. Then Ingo asked whether the Russians might have built a moon base, and Axelrod wouldn't answer him one way or the other.
