...Administration and the media have condemned Moscow for its late disclosure of the accident and for its relative silence on its seriousness. But at the time of the TMI crisis, President Carter certainly wasn't letting us know how bad things were. While federal experts were predicting a hydrogen explosion, the President was telling Harrisburg residents that they weren't in great danger and that an evacuation would be "strictly a precautionary move...
Technical research is focusing on developmentof an array of potential systems including lasers,satellite "eyes," infrared detectors, and a"neutral particle beam weapon" which fires streamsof hydrogen atoms through space, he said...
...comet on March 9, supplementing Vega 1's findings. Giotto's mission four days later was to swoop to about 300 miles of the nucleus, shooting close-up pictures as it passed. Precision pathfinding was less important for the Japanese craft. Suisei, designed to study the huge hydrogen gas cloud surrounding Halley's, was targeted to fly by the comet at a distance of almost 100,000 miles. Sakigake, studying the solar wind so that scientists can determine the wind's effect on the comet's tail, would not come closer than 4.4 million miles from the nucleus...
...fact, Halley's spectacular show did not go entirely unobserved. Last week scientists at NASA's Ames Research Center in California proudly displayed computercolored ultraviolet images of Halley's hydrogen coma as it appeared between Feb. 2 and 5, and described the changes in the comet during its most active period...
...Feynman probed further, he was told by NASA that the surface temperature of the external tank, which contains supercold liquid oxygen (-297 degrees ) and hydrogen (-423 degrees ) had not been abnormally cold, casting doubt on a theory that liquid fuel, leaking unnoticed from the tank, had chilled the nearby booster. He also discovered that the wind on the morning of the launch had been blowing across the cold surface of the tank toward the right booster. As one NASA engineer explained, "Even a slight breeze, wafting over the external tank full of those cryogens (supercold fluids) may have been enough...
