...earth, or did it form separately out of the same primordial dust cloud? Was it a planetary interloper captured by the earth's gravity when it wandered too close, or did it coalesce from small asteroids in orbit around the ancient earth? Did it ever have an atmosphere? water? life...
...tons of phosphorous, 9 billion tons of carbon, 6 billion tons of copper and 3 billion tons of cobalt on or near the lunar surface. If their figures are correct, the meteor fall would also have contributed 300 billion tons of carbonaceous chondrites, containing about 30 billion tons of water chemically locked in crystals with other compounds...
...fierce beams on a target. Using these, Zwicky suggests, man could work wonders with lunar rock. The furnaces could melt lunar gravel and soil, which could be cast into bricks for building shelters. They could also be used to heat moon rocks enough to release their locked-in water. Even the proverbial pig's squeal could be used. Water vapor steaming out of the heated rocks could drive power turbines before being condensed into drinking water. When lunar water is finally available in ample supply, it could even be used for rocket fuel. Moon technicians will decompose it into hydrogen...
Zwicky would also produce carbon dioxide by focusing the rays of a solar furnace on rocks containing calcium carbonate. The carbon dioxide would be released into the atmosphere of a covered garden to sustain green algae living in a tank of water. The rapidly reproducing algae would not only be an excellent source of protein for humans on the moon but would also produce vitally needed oxygen as a byproduct of photosynthesis...
Astronomer I. M. Levitt, director of the Pels Planetarium of Philadelphia's Franklin Institute, believes that colonizers of the moon will eventually produce their own water, a contained atmosphere, food and other necessities completely from lunar materials. He envisages vegetables grown from seed, rooted in tanks of water in which the necessary lunar minerals have been dissolved. His moon colonies, complete with farm animals and factories, launch pads and lunar surface vehicles, and the comforts of home, would be located underground?in sealed-off caves and domes?to protect inhabitants against meteors, solar radiation and the extremes of lunar temperatures...
