The Cold War
Some argue that we know more about what’s in space than what’s under our feet. Have you ever heard of a space race? It’s a race between two Cold War rivals, the Soviet Union (USSR) and the United States (US), to acquire superior spaceflight capabilities in the twentieth century. It is significant because it demonstrated to the world which nation had the greatest science, technology, and economic structure. And we have achieved much, but few people are aware of the conquest to conquer the land.

Race To The Depths
Since the late 1950s, scientists from the United States and the Soviet Union have been working together on an experiment to explore the Earth’s crust. The crust is the Earth’s lightest and most buoyant rock layer. The continental crust spans 41% of the Earth’s surface, with the seas covering a quarter of that area. The continental crust has a thickness of up to 30 miles. Then there’s the mantle.
