I theorize that there is a spectrum of consciousness available to human beings. At one end is material consciousness. At the other end is what we call 'field' consciousness, where a person is at one with the universe, perceiving the universe. Just by looking at our planet on the way back, I saw or felt a field consciousness state.

I don't think there is much value in trying to use the moon as a base to go to Mars. That's going into one gravity belt and having to get back out of it again. And the moon doesn't have a lot to offer as a resource base.

At the end of October 4 in 1957, when I was coming back from sea duty in the South Pacific, Sputnik went up. I realized that humans would be right behind robot aircraft or spacecraft even though I really had no plans of being in aviation or a professional aviator and certainly not in the military.

The best experience that we have on Earth is the fact that we have scientific stations, weathering over stations down in the Antarctic for almost the entire 20th century to learn how to exist in exceedingly hazardous conditions; and the Moon is far more hazardous than Antarctica. At least they have water there.
