For the first time scientists will drill all the way to the Earth's mantle to retrieve valuable samples.
The project is not without its complications - in order to work it will require new drillbit and lubricant designs as well as rather a large amount of money, however scientists are optimistic that drilling could go ahead around 2020.
Scientists are planning to drill all the way through the planet's miles-thick crust to Earth's deep, hot mantle and retrieve samples for the first time. The samples, they say, would rival moon rocks for sheer scientific importóand be nearly as hard to get.
