Edgar Mitchell on space travel and the 'big picture effect'

Here's an interview I did with astronaut Edgar Mitchell, sixth man to walk on the moon, about how the experience of space travel has transformed him and many other astronauts. It's for a chapter of my (hopefully) forthcoming book, which looks at how the ancients used astronomy or star-gazing as a spiritual exercise for self-transformation. For best results, make it full screen, listen with headphones, and trip out!
