Summary:
A Japanese-led project aims to drill to the Earth's mantle, a 3000 kilometer-thick layer of slowly deforming rock between the crust and the core. In its early stages, the $US1 billion mission would deploy a drill just 30 centimeters wide to bore into the Earth's crust to bring back the first ever samples of fresh mantle rock.
