...gone through what meteorologists call a "cold soak," conditions more severe than those at any of the previous 24 shuttle launches. NASA manuals say that the solid fuel in a booster should be ignited only when the rubber-like mixture is between 40 degrees and 90 degrees . Morton Thiokol, the rocket manufacturer, also specifies that the fuel's temperature should never be allowed to fall below freezing. The insulated boosters contain no internal heat sensors, but NASA technicians calculated the mean temperature to be 55 degrees...
When the Columbia space shuttle rises from its Kennedy Space Center launch pad this week, some anxious businessmen in the U.S. and Canada will be glued to their television sets, and not just to marvel as the reusable spacecraft's twin Thiokol rockets thrust it up and over the blue Atlantic. The launch, fifth in the Columbia series, will be the first in which the shuttle begins earning money from private, corporate customers for the National Aeronautics and Space Administration...
...Commoner on ecology. With so many books to read, with figures dwarfing anything Scott's talking about (anything imaginable), it's chaos to lose the bond of shared experience for too long. When the New York Times can ignore an industrial explosion that killed 29 workers in 1971 (the Thiokol Chemical Corp. plant in Woodbine, Ga.), it's essential that Scott's subject either stay humanized or be numbered and forgotten...
Space-Age Box. Developed by Thiokol Chemical's Humetrics Division, the device is called ElectroCardioAnalyzer. It is a miniaturized computer as well as a simplified electrocardiograph. By comparing a subject's graph with fixed standards that have been programmed into the machine beforehand, it can detect abnormal electrical activity in the heart. When it -does so, warning lights flash on, and the technician knows that this patient must be referred to the cardiologist...
...against cardiologists using ECG machines. The new device thought it saw abnormalities in 5.6% of cases where they did not exist, which only meant a bit more work for the experts. On the other hand, it failed to detect a real abnormality in 2.7% of the cases examined. But Thiokol scientists say this percentage can be reduced by technical changes...
