The Earth's Core - Rocket Rights

Now available from rocketrights.tv (usa) is this incredible DVD made by Pioneer Productions for National Geographic's "Naked Science" series.

What lies at the centre of the Earth?
There is a place on Earth that we have never seen. It is a place of unimaginable heat and pressure, where no life could survive and yet without it we would perish. 2000 miles below the Earth's surface there is a vast ocean of molten iron. The spinning outer core of the Earth generates a protective magnetic shield around the planet defending life from lethal space radiation. But now there is startling new data that it could be about to stop defending us. Professor Dave Stevenson explores a mission to the centre of the Earth that would need a magnitude 7 earthquake to penetrate its surface. Could a person ever make it to the core of Earth
