Scientists in Japan have announced an audacious plan to drill through the ocean floor and into the Earth’s mantle for the first time.

It’s thought that the molten interior could hold clues to predicting earthquakes and even reveal how the Earth formed more than 4 billion years ago.

In September, staff at Japan’s Agency for Marine-Earth Science and Technology (JAMSTEC) will search for possible drilling sites off the coast of Hawaii.

There were previous attempts - by the Russians, I think - but they failed. I hope the Japanese succeed.

Probably also Japan, sometime ago. Using a deep sea submarine, something like that.

Perhaps Japan always wants to explore various sources of resources.

The problem with such deep drilling isn't just that the rock at such depths is semi-molten, it's also the enormous pressure. They drill a hole and then the pressure crushes the hole and the drill.
