...trapped in the ground or returned to earth by the falling debris. Purpose of the explosion: to test the feasibility of using thermonuclear devices to speed up massive civil-engineering projects, such as the digging of harbors, tunnels and canals. In the desert floor, the blast gouged out a crater 300 ft. deep and one-third of a mile wide. And at week's end, the U.S. fired off a low-yield nuclear device a few feet above the desert floor for the first atmospheric test in the U.S. since...
...space traveler who happened to be standing on the dark side of the moon last week, in the mountains southeast of the crater Albategnius, would have been startled to see 13 brief red flashes flame up on the dark side of the distant earth. The unexpected spurts of light marked the position of Lincoln Laboratory near Lexington, Mass. They came from a ruby laser-a source of pure light of a single frequency-fitted into a 12-in. telescope...
...memories of the weary scientists, including Ogle, who sweated them out. There was Ranger at Frenchman Flat near Las Vegas, Greenhouse at Eniwetok, Buster-Jangle and Tumbler-Snapper. With Ivy in November 1952, the first hydrogen bomb was exploded, wiping out the tiny island of Elugelab, and digging a crater a mile long and 175 ft. deep in the ocean's floor, near Eniwetok. During Castle, near Bikini in the spring of 1954, miscalculations on power and meteorology caused radioactive ash to fall and injure 23 Japanese tuna fishermen-one fatally-on their trawler, Lucky Dragon, which...
...from a captive balloon. However it was hoisted, the bomb's height was carefully chosen to minimize local fallout. If the fireball did not touch the ground before it stopped expanding, little or none of its radioactive material would mix with pulverized soil blown out of its massive crater...
...LOCAL FALLOUT. This is mostly the coarse, comparatively heavy material blasted out of the bomb crater. Although extremely dangerous, it spreads only a few hundred miles from the explosion. It does not get into the long-term circulation of the atmosphere, and it does not threaten the earth as a whole...
