...roar farther and faster, rockets need a super-fuel with more bounce to the ounce. Most such concoctions are too volatile to handle. Last week Bell Aircraft announced success in taming one of them-liquid fluorine-which might boost rocket-payloads 70%. That would be enough to orbit U.S. satellites considerably bigger than Russia's very heavy Sputnik...
...rocket fuel combines a chemical that oxidizes and an ingredient that burns. The propulsive energy released is measured as "specific impulse." Present combinations, e.g., liquid oxygen and kerosene, have a specific impulse of about 245 Ibs. Using liquid fluorine as the oxidizer instead of liquid oxygen would boost specific impulse to between...
...captious sea is at once Admiral Jimmy Thach's ally and enemy. Sound, his chief means of detection, travels almost five times faster through water than through air, and it plays more tricks than a Soviet delegate at a peace conference. "The ocean," says Thach, "is a liquid jungle. Survival depends on how well we know this environment and whether, like Tarzan, we can tell the friendly sounds from the unfriendly ones-the monkeys from the tigers...
...lightness that they allow in a nose cone. A solid-fuel missile like the projected Air Force Minuteman ICBM (due in 1963) would be badly overloaded with a heavy copper nose. Now the Minuteman will reportedly get a sharper, ablative nose, as may later advanced versions of the liquid-fuel Atlas and Titan, thus returning advanced missilery to orthodox streamlining...
...stream, they got native chieftains to pass the word by jungle telegraph. At their chieftains' bidding, 215,504 men, women and children trooped down to rally points where the doctors were waiting with jugs of ice-cold Chat. In some cases, team members squirted the virus-containing liquid into the tribesmen's mouths; usually, they let them take it from a tablespoon. There were no ill effects, and team members have high hopes that they averted a lot of polio...
