From Sightings Article on 2001 and Kubrick:

"After finally landing on the moon Floyd gives a strange speech explaining how they must keep what they have found completely secret. The news of this importance could cause severe psychological problems with the good citizens back on earth. He tells the group of scientists and military men that humans on earth will have to be 'conditioned' to accept what it is that they found. Floyd blandly explains why is it so important that they must concoct a cover story. A story that says an epidemic has broken out at the American moon base. Kubrick reveals, in this scene, the contempt that our masters of the Military Industrial complex hold for us. The truth of something amazing must be held secret from us until we are conditioned to receive it. This is done with such a masterful sleight-of-hand that it is never really considered much by the viewer. The Pentagon, NASA, or someone, is hiding the most astonishing fact of all from the rest of the human race. And everyone on the screen shakes their head in approval without considering the import of what it is they are doing.

But what is it that they found? We discover the secret in the next sequence, which is also the last part of chapter two. In a series of shots that still shimmer in the memory of the viewer, Kubrick takes us on a tour of the moon on a space bus. It is dark, but the horizon shows the oncoming light of the sun. Even here, the men involved are soulless and lifeless. No jokes are evident as humanity's sense of humor is seemingly void and null. Again, the men eat revolting food as they blandly discuss, what is apparently, the most important discovery in all of human history. The mysteries are slightly cleared up in the next scene. Apparently, a simple magnetic survey of the moon, done by the Americans, has revealed that something was giving off an anomalous signal, just 5 meters underneath the surface of the moon. The Americans, who have discovered the signal, have dug it up. They discover that it is a black monolith buried under the soil of the moon that is emitting these frequencies. When it is finally seen, we find that it is exactly like the first monolith that the apemen encountered in chapter one. Who buried it and why? Once again Kubrick never answers these questions. Again, the men involved with the discovery - essentially the greatest find ever in earth's history - act in a manner that is completely banal. They begin snapping photographs of themselves in front of the strange, black slab of stone. The scene on the moon has been cloaked in the darkness of night until now. But now the sun rises just over the horizon. It's light strikes the black monument for the first time since it has been buried, presumably four million years ago. As the light strikes the monument it suddenly emits a high pitched signal that pierces through the ears of the men."
