Journey Toward the Center of the Earth

Sixty years ago, geologists tried to drill down through the Earth’s
crust to pull up a piece of the Earth’s mantle. Their mission
didn’t go exactly as planned. But it sowed the seeds for a new

the planet, but, potentially, our definitions of life itself. The
documentaries featured in this episode are "The First Deep Ocean
Drilling: Mohole, Phase 1" and "Project Mohole: Report No. 1." For
