Journey to the Centre of the Earth

NZer David J. Stevenson – a planetary scientist at the California Institute of Technology – has a project up his sleeve straight out of science fiction, but grounded in the search for science fact.    Stevenson’s proposal – outlined in May’s issue of Nature – is to create a fissure reaching the earth’s core, into which an investigatory probe will be sent. Stevenson: “We know so little about Earth itself. We’ve been billions of kilometers out from Earth, but only 10 kilometers into it.”
