Johann Kepler advocated Copernicus's heliocentric theory in his Dream and Notes. He imagined how a moon dweller would see the solar system and the conclusions he would draw. Then by reversing the point of view to the earth, Kepler showed that the same conclusions would follow. This involved concepts of mass, inertia, gravity, acceleration, velocity, and the driving force in a trip to the moon. Twelve years before Newton's birth in 1642, Kepler published in this little known dream ideas which Newton later developed. Kepler's ideas concerning the moon's distance, motion, and conditions to be met in space are reviewed.
