In 1971, he was the sixth man to walk the surface of the moon. Traveling back to Earth, through the abyss between the two worlds, Apollo 14 astronaut Edgar Mitchell had an experience for which nothing in his life had prepared him.

He retired next year, and soon after started Institute of Noetic Sciences to bridge science and spirituality.
