...Tighteners? A few days later, when the Chemical Society held a second regional meeting at St. Louis, its president, Dr. Charles Allen Thomas of Monsanto Chemical Co., gave his flock a timely talking to. He did not come right out and call the chemists dodos, but he warned them that overspecialization (the nemesis of the dodo) might make their science stagnate...
Rockets that have been turned into efficient "guided missiles" may some day wreck civilization. Meanwhile, they are useful in telling man more about the universe. At a recent meeting in Oslo of the International Union of Geodesy and Geophysics, Dr. J. A. Van Allen of Johns Hopkins gave a general outline of the work that rockets have already done...
Higher & Higher. Most rocket-borne research, said Dr. Van Allen, has been done by V-2s captured in Germany. Up to July 1, 31 of them had been fired at White Sands Proving Ground, New Mexico, "with upper atmospheric equipment as the primary payload." Twenty-one flights were successful, and one of the rockets reached an altitude of 184 kilometers (114 miles). Some of the information gathered was sent back by radio "telemetering." Other rockets blew off their noses, so that the instruments and records in them would hit the earth less violently. Parachutes brought some instruments drifting gently...
...expensive and clumsy. So, said Dr. Van Allen, the U.S. has developed a smaller, simpler and cheaper missile, the Aerobee, which is good enough for carrying instruments above the atmosphere. It has "two-stage propulsion." A booster brings its velocity to 300 meters per second (670 m.p.h.) and then drops off. After that, a "sustaining" rocket motor speeds it to 1,300 meters per second (2,900 m.p.h.). The Aerobee has carried a payload of about 150 lbs. to 115 kilometers (71 miles...
...Allen's heartening conclusion: "I am not worried. While television is making up its mind, radio marches on! It may be a treadmill-but RADIO MARCHES...
