Green has long believed that most of the major lunar features are volcanic in origin. Since volcanic formations on earth contain hydrous rocks, Green reasons, they may well exist on the moon. Merely heating such rocks to between 500°F. and 800°F., he says, will release as much as a gallon of water per cubic foot of rock...
...spots near the crater Aristarchus, from which astronomers have reported seeing a red glow-a possible sign of volcanic activity. To Geologist Green, it all makes sense. Sulphur is the most abundant of volcanic materials, he says, and wherever volcanic sulphur is found on earth, it is surrounded by hydrous rock...
Carrying his speculations one step further, Green suggests that if life or its fossil remnants are found anywhere on the moon, it will probably be in the vicinity of the telltale black spots on his moon photographs. In the water released from hydrous rock by volcanic heat, he speculates, a primitive form of life might have evolved...
Whether lunar life did evolve or not,, it would be worthwhile for astronauts to land near Aristarchus. There, by focusing solar rays on the hydrous rock, Green says, they can assure themselves of an ample supply of water...
