USSR DRILLING TO THE CENTRE OF THE EARTH – The Kola Superdeep Borehole During the Cold War, the Soviet Union launched an ambitious scientific project to explore the Earth’s crust by drilling deeper than anyone had before. The aim was not to reach the Earth’s core — which lies about 6,371 km below the surface — but to understand the structure, composition, and history of the continental crust. LOCATION AND TIMELINE Site: Kola Peninsula, north-western Russia Project Start: 1970 Deepest Point Reach
