How far have we ventured into space? As of 2024, the American space probe ”Voyager 1” is located beyond the Solar System, at a distance of 24 billion kilometers from Earth. However, our progress toward the Earth’s core has been significantly more modest. The deepest drilling depth ever achieved was in Russia, at the Kola Superdeep Borehole. By 1990, it had reached a depth of 12,262 meters. At the time, science and technology were not yet advanced enough to go deeper, and economists did not see any clear prospects for further exploration.
