...safety of their triple-sealed vacuum storage boxes, the lunar samples will be rushed to the LRL even before the Apollo 11 crew members arrive to wait out their 21-day quarantine period. There are "time-critical" tests that must be performed swiftly to detect any gas or radioactivity that the samples may give off; the emissions may decrease or stop soon after the sample is removed from the lunar surface. The samples will be sealed off from the rest of the world by a double biological barrier: 1) a vacuum system and a series of vacuum chambers in which...
...environment that makes the moon so hostile to terrestrial life is, paradoxically, precisely what makes the moon so potentially valuable. The absence of atmosphere, which exposes any life on the moon to deadly radiation and the inhospitable vacuum of space, also makes the moon an ideal base for observatories and some industries. Meteors which have battered the lunar surface for eons have probably also endowed the moon with immense mineral wealth. Although lunar days and nights are each two weeks long and accompanied by deadly extremes of temperature (ranging from 240 degrees Fahrenheit above zero to 250 below), both...
...problem, Rand Corp. Researcher George Kocher suggests actually building a large mirror on the lunar surface, using quartz produced from silica?if it exists on the moon?and giving it a more accurate surface than terrestrial mirrors by shaping it with ion beams (which are effective only in a vacuum) instead of abrasives. Several astronomers have pointed out that round lunar craters lined with chicken wire would make ideal reflectors for radio telescopes similar to the 1,000-ft. Cornell University radio dish, set in a rounded valley near Arecibo, Puerto Rico...
Near Perfect Vacuum...
...find the moon economically irresistible. Anywhere they choose to locate on the 15 million square miles of lunar surface, there is a near perfect vacuum?a condition that is obtained on earth only with thick walls and elaborate pumps, and at great expense. As the need grows for "hard" vacuums in industrial processes on earth, the day may come when certain lightweight, easily transportable items that require a vacuum in their production?electronic tubes, computer components, hearing aids ?can be made more economically in lunar factories...
