Just picture two points on a ball, inside a room with a picture on the wall. If the two points are at the top and bottom of the ball, they could both conceivably see the picture despite the ball spinning. Now place those two points further down, and in a more horizontal plane, and they only see the object when they rotate toward the wall with the picture. All I'm saying (the picture is the moon). Anyway, I think there are easier FE arguments, this one gets tricky. Rest assured, the truth will hopefully be revealed soon. Simone has got to send something up independently to see this thing and settle it. Hopefully soon, one way or the other.
