Oh? I'll slow down for you. It would be amazing that the sensors on both spacecraft were not functioning when entering Lunar Orbit. It should be no mystery that certain elements have certain densities. It is stated that both craft, "have provided unprecedented detail about the interior structure." The usage of "have provided" states that the operators know what's there, and have already evaluated the data. Both craft have passed over the same surface multiple times; at this point, if anything had changed, that would be intriguing. Outside of Tralphium,(google it), there is nothing in a raw state that is cheaper to obtain from the Moon, then one can purchase on Earth, locally. So why the mystery? At this point, the results should be a Blender3D model showing various multi colored splotches indicating various elements in overall large concentrations.
10 years to get to the Moon, and 40 years of watching re-runs. At this point, the American People should all be considered candidates for Beatification. Or another analogy I'm fond of is, "A first year Geology Major could learn more about the Moon in one day using a Bucket and a Shovel then all of humanity currently knows."
And I think it still holds true, today.
