"in 1974 I experienced an invasion of my mind by a transcendentally rational mind, as if I had been insane all my life and suddenly I had become sane."

| Finely Divided Dust Propellant | ||
| Reaction mass to drive spacecraft. |
| ...for all the problems it presented him, Man could not do without the Moon. It had been his first bridgehead in space, and was still the key to the planets. The liners that plied from world to world obtained all their propellant mass here, filling their great tanks with the finely divided dust which the ionic rockets would spit out in electrified jets. By obtaining that dust from the Moon and not having to lift it through the enormous gravity field of Earth, it had been possible to reduce the cost of space-travel more than ten-fold. Indeed, without the Moon as a refueling base, economical space-flight could never have been achieved. |
