Half-a-century ago, at the height of the Cold War, the Space Race between two competing superpowers set mankind on an accelerated path toward placing a man on the moon.

In more recent years, many surprising discoveries have challenged scientists’ long held ideas about the moon’s history. Today, we begin exploring the evidence that high-energy electrical discharge events in the past have defined the lunar surface.
