Date de diffusion: Mai 07, 2009

An imaginary vehicle circling the planet is used to highlight the surprises that exist beneath the Earth's crust. Life is discovered in the crust deep in a South African gold mine; a huge gun is fired to determine how crust reacts to an asteroid. Another scientist proposes a new theory to explain how diamonds move from the Earth's mantle to the surface.
