Japan aiming to be the first to drill into Earth's mantle
Japan-based researchers are planning to be the first to successfully drill into Earth's mantle, beneath the crust. Japan's deep-sea drilling vessel will drop down 4 km in the Pacific and bore through 6 km of the ocean floor, researchers said. The project to study oceanic crust and probe microbial life's extent inside the Earth is planned to start by 2030.
