Moon

S1 E4: Nothing could be more familiar to human eyes than the Moon; yet nothing could be stranger. None of our near neighbours in the solar system – Mercury, Venus or Mars – has a moon like ours, a companion in space so large that it rules our nights, our months, our ocean tides. Why Earth should have such a moon is one of the deepest mysteries of the Solar System. Moon tells the story of how the Earth’s satellite became the object of desire of the two Cold War superpowers, and how scientists jumped on the political bandwagon to solve the riddle of the century.
