Edgar Mitchell, who passed away in February at the age of 85, was exceptional, even among astronauts. Like an archetypal moon man, he was a Boy Scout and a military test pilot with a protestant upbringing and an impressive command of engineering and aeronautics. In February 1971, on Apollo 14, he became the sixth man on the moon. But more so than other astronauts, Mitchell’s brief exploration of outer space led to a deep exploration of inner space and the entire universe of phenomena explained and not. After conducting an ESP experiment in space, he became a connoisseur of parapsychology; later, he sought to show that aliens had visited Earth and that governments around the world had tried to cover up the truth. But he remained grounded on Earth too, and worried that civilization's narrow perspectives were exceedingly dangerous for the future of the planet and humanity.
