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.
