     […] [T]he moon's familiar patchwork of dark and light splotches. It's the only side of the moon we ever see from home base, a result of Earth's having yanked its satellite into a so-called tidal lock: The time it takes the moon to rotate once on its axis is the same as the four weeks it takes to orbit Earth, which means the same side is always turned toward us.
