...akin in geological evolution and structure, and that the moon was made of earthlike layers. Now more careful study is showing that these initial ideas have almost as many holes as the moon itself. Not only have the rocks sprung such chemical surprises as an unusually high content of titanium, but the moon's seismic activity is also not what it had seemed...
...contains an element that is basic to life on earth. Johnson found only 25 parts per million of such compounds in his lunar sample, compared with perhaps 10,000 p.p.m. in a typical backyard sample of the earth's soil. The scientists also confirmed a surprising abundance of titanium on the moon. Though this space-age metal, vital in the manufacture of heatresistant parts for jet engines and rockets, is relatively rare on earth, one lunar sample was assayed at 6% titanium...
...quite-but in St. Louis that view is understandable. One reason: the National Lead Co.'s titanium pigment plant routinely emits a sulphuric acid stench that is downright sickening. The city is also a booming center of the chemical industry, prolific source of exotic effluents like phthalic anhydride and chlorinated phenolic compounds, which make the eyes water and smell like the medicines children swallow while holding their noses. All too often St. Louis stinks, as one resident says, "like an old-fashioned drugstore on fire...
...Lofted into orbit high above the earth, satellites even now are relaying radio and TV signals across thousands of miles of ocean and gathering a wealth of weather information. In years ahead, they may be used to monitor crops and survey mineral resources. In metallurgy, extremely strong and anticorrosive titanium alloys have moved from the launch pad to the machinery of chemical and power plants. Several utilities are already testing chemical fuel cells of the kind that Apollo carried to the moon to determine whether they might offer an efficient, contamination-free method of generating electricity on earth...
...drive the SR-71 in a missile-like ballistic curve that takes the plane above 97% of the earth's atmosphere. Yet even in the rarefied upper atmosphere, the surface temperature of the plane's leading edges hits 630°, enough to heat the Blackbird's titanium skin to cherry-red incandescence. An intricate system of pumps and pipelines circulates fuel near enough to the skin to absorb heat and carry it to cooler parts of the plane where it is radiated away. Even so, if the space-suited two-man crew cannot take time to cool...
