Or first moon landing in 1963, Mars by 1968... Man Conquers Space
All we know is that the waste dumps were on "farside" (incorrectly called "Dark Side" in the opening scene). If just over the limb on the correct side, the Moon might have taken off on a tangent. Dead center on farside and the Moon might have dove inward, grazing Earth. Just over the limb on the other side, well, the Moon might have spiraled in and crashed into Earth. But then the show would have ended right there.
