He mentally reviewed his notes. Here he had intended to be more specific about the nature of that drift. If it’s in a higher orbit, it’ll fall behind. If it’s in a lower orbit, it’ll race ahead. If it’s off to one side or the other, it’ll converge, then diverge, on a ninety-three-minute cycle. Only if it’s directly forward, or directly aft, will it maintain the same relative position. But he thought maybe he could link that out to a different video, one with more graphics. Better to get to the point.
