President Harold Ritchie of Thiokol is confident that in 2½ years he can have a cluster of four solid-fuel motors with 28 million Ibs. of thrust flying at a cost far below the price of an equivalent liquid-fuel booster. A cheap backup booster with such enormous power might easily save the moon program from half a decade of frustration...
...causes as heartburn. An antacid tablet may help. The catch is that the layman usually cannot tell the difference between this and a medically significant form of indigestion. This inflammation of the stomach (gastritis) is part of the pattern of peptic ulcer. Then the trouble is not a simple backup of the evening's Scotch, steak and potato but a too-free flow of hydrochloric acid and other digestive juices from the stomach walls into the stomach itself and the duodenum. The excess juices find a vulnerable spot in the stomach wall or duodenum and, in effect, digest that...
...greatest promise offered by microcircuitry, apart from smallness, is reliability. Using 1,243 microcircuits, Sperry Rand has compressed a big Univac computer into a 6-in. box; it is expected to run continuously for two years. Since microcircuits are so tiny, several backup circuits can be installed to take over automatically when one fails, thus extending the life of electronic equipment almost indefinitely. Best of all, the microcircuits will eventually be cheaper than conventional circuits because they will combine the production of a welter of separate components into a single manufacturing process, are easier to install and can be produced...
...contractors, NASA reported, delivered capsules with more than 500 defects, and spare parts that were more than 50% defective. On Mercury's six manned flights, there was an average of ten equipment malfunctions-any one of which might have resulted in fatal failures. Only emergency backup systems and the skill of the astronauts in manual control saved the missions...
...During inspections before Glenn's flight, it was discovered that electrical connectors had been improperly soldered in the escape towers of both Glenn's capsule and his backup capsule, leaving the escape devices useless...
