...piecing together radar and telemetry data, film sequences and fragments of wreckage dipped from the shallow waters off the cape, missilemen managed to figure out what went wrong: the loft. long fiber glass "nose fairing" that was supposed to protect the third stage and payload from air friction and buffeting in the upper atmosphere fell off prematurely, after 40 seconds instead of the programed 4½ minutes. Then the fierce drag of the atmosphere wrenched the payload-carrying third stage loose, made the second stage malfunction...
...today's technology, crude as it is. He could, suggests Air Force Lieut. Colonel S. E. Singer in the Air University Quarterly Review, store the sun's abundant heat energy (daytime heat 248° F.) with inertial flywheels (which are inefficient on earth because of atmospheric friction), and control his heating during the −200° F. cold lunar nights. He could, adds Physicist Singer, extract water from rock; then from the water, by means of electrolysis, could come oxygen to sustain him, and hydrogen for fuels and chemical synthesis, and for growing food by hydroponics...
...heat concentrated on rather small areas. The beauty of Pyrographite is that it conducts heat away from these danger points as fast as copper can, but it does not permit nearly as much heat to pass through it. A Pyrographite nose cone, for instance, spreads the heat of air friction over a large area and permits it to be radiated harmlessly away, but it does not let heat strike through the cone and damage the sensitive instruments or warhead inside...
...surprised at this turn of events. The fact that China's revolution occurred later, its doctrinaire line and insistence on "communes," and the traditional fear of Russian expansion into China--these factors will continue to create friction between the two powers regardless of what happens to India and to the Russian disarmament proposal...
...three-man commission appointed to study town-gown friction in New Haven has published a series of proposals to improve relations between Yale and the surrounding community. Named on March 30 by Richard C. Lee, Mayor of New Haven, the commission was set up after riots following a St. Patrick's Day parade caused the arrest of 16 students...
