...slow,.sad task of cleaning up after Camille began, a new hurricane, Debbie, began moving northward from the Caribbean. In an effort to reduce its intensity, a 13-plane armada attacked its core with silver-iodide crystals, designed to bring down Debbie's temperature by turning her water vapor into rain or sleet. Debbie shrugged off the effort and continued moving on her course...
...dust -which seemed to explain what Astronaut Buzz Aldrin meant when he described the lunar surface as slippery. Geologists tentatively ascribed the abundance of the glassy material to meteors. Because of the immense heat generated on impact, speculated Harvard's Clifford Frondel, the invading material would have been vaporized, along with chunks of the lunar surface. After cooling, the vapor may have rained back in the form of glass spheroids. But that explanation raised a baffling question: Since lunar gravity is not even strong enough to retain an atmosphere, why did the vaporized material-not drift off into space...
...satellites sent into orbit by Martians. But they would have to be unlike any terrestrial creatures. More than ever, Mars seems hostile to most earthly forms of life. Its surface appears exceptionally dry; its atmosphere seems to be composed largely of carbon dioxide with only a trace of water vapor...
...could work wonders with lunar rock. The furnaces could melt lunar gravel and soil, which could be cast into bricks for building shelters. They could also be used to heat moon rocks enough to release their locked-in water. Even the proverbial pig's squeal could be used. Water vapor steaming out of the heated rocks could drive power turbines before being condensed into drinking water. When lunar water is finally available in ample supply, it could even be used for rocket fuel. Moon technicians will decompose it into hydrogen and oxygen gases by electrolysis, then feed the gases into...
...recent months, the nature of the arcane arsenal's components has gradually been revealed. In the chemical-warfare category, one of the most lethal gases is Sarin (GB), which in heavy vapor doses attacks the victim's nervous system and reduces him to a convulsive mass before death occurs. Fifteen years ago, the commanding officer of the Army's Rocky Mountain Arsenal estimated that a single drop of the nerve gas in liquid form on the back of a man's hand could kill him in 30 seconds. Sarin has been improved since then. The Army...
