Chinese scientists have begun drilling a 10,000-meter (32,808 feet) hole into the Earth’s crust, as the world’s second largest economy explores new frontiers above and below the planet’s surface.
Drilling for what is set to be China’s deepest ever borehole began in the country’s oil-rich Xinjiang region on Tuesday, according to the official Xinhua News Agency. Earlier that morning, China sent its first civilian astronaut into space from the Gobi Desert.
The narrow shaft into the ground will penetrate more than 10 continental strata, or layers of rock, according to the report, and reach the cretaceous system in the Earth’s crust, which features rock dating back some 145 million years.
