Thus far, the H-bomb's fail-safe systems have not been foiled even by shattering falls from high altitudes, as happened at Palomares. In that accident, two hydrogen bombs split open on impact and spilled plutonium, dusting nearby farms, which had to be tediously decontaminated. The same kind of low-level alpha radiation, officially described as "negligible," was discovered on the icebound bay off northwestern Greenland last week. The U.S. airmen who detected the radioactivity reached the blackened, 500-yd.-long crash site on Eskimo dog sleds, the only means available in the swirling snow and 50-m.p.h...
...years ago, the flash of a fireball last week lit up the desert around Lop Nor in northwestern China. It was the first test since last spring, when a Maoist mushroom cloud proved to the world that the Chinese had succeeded in the summa of atomic arts-building a hydrogen bomb. Bang No. 7 was far, far smaller, probably in the Hiroshima-bomb range of 20 kilotons. But it was no less menacing for being a minibang. Unless it was a partial dud-as Peking's unaccustomed silence, led some to believe-its improved miniaturization indicated that China...
...saliva. Another gas usually ingested in harmless quantities is carbon dioxide, from the bubbles in soft drinks and the soda in Scotch and soda. But the body is also a versatile gas factory. By fermentation and similar processes, it can manufacture an excess of carbon dioxide, as well as hydrogen, methane (all odorless) and hydrogen sulfide (which has an unpleasant odor). At times, excessive production of such gases can be painfully serious...
Cutting in after the first stage was jettisoned, the liquid-hydrogen-fueled SII second stage fired flawlessly, providing 1,000,000 Ibs. of thrust and boosting the rocket to an altitude of 115 miles before it, too, was jettisoned. Now it was the turn of the third-stage S-IVB. Firing its engine, it inserted itself, the attached Apollo spacecraft, its service module and the lunar module-a total of 140 tons-into orbit, with an apogee of 119 miles, a perigee of 114 miles. It was an impressive demonstration that, after ten years, the U.S. had finally overtaken...
...discoveries during the 1930s concerning the energy production of stars. A German-born scientist who fled the rising Third Reich and who has been teaching at Cornell University since 1935, Bethe (pronounced Baytuh) theorized that the inordinate energy emitted by stars results from two protracted nuclear processes during which hydrogen fuses into helium. Similar research placed Bethe in the front rank of atomic-era scientists such as Edward Teller and Robert Oppenheimer who gave birth to the Abomb...
