In 1970, a team of Russian geologists started a mission in Finland to see how far they could drill into the Earth. The team dug and dug until they came to a depth that melted the drill bit. Nearly 20 years' worth of hard laborculminated in drilling only 12 kilometers under the surface, which in 1989 was the deepest artificial point anyone had ever reached. Since then, there have been two oil wells in Qatar and Russia that have gone deeper. One question remains, though. How is it possible to send rovers to Mars, which is at least 54 million kilometers from Earth, but only drill down a few kilometers with all the modern technology we have?
This month, National Geographic Channel (NGC) takes viewers on a journey from the concrete sidewalks of our city streets to the center of the planet 9,000 kilometers below in an astonishing single shot on Down to the Earth's Core. Delving through the crust, the mantle, the outer core, and the inner core, NGC uses computer-generated imagery to explore the hidden world beneath our feet. Viewers will experience an earthquake from inside the San Andreas Fault, see how stalactites and gold form, witness the death of the dinosaurs, and understand the power of volcanoes all from underground. While humans have only been able to make it 12 kilometers below the surface in real life, NGC's Down to the Earth's Core shows wonders beyond our imaginations that lie at the heart of our planet.
