...Gallup poll on whether Dulles is right to keep U.S. troops in Kremlin-menaced Berlin [Dec. 29]. The most interesting result is not that 60% of those polled agree with Mr. Dulles but that almost one-fourth are not familiar with the problem that might bring on World War III. What we probably need is fewer public polls and more public education...
...Domains. Scurrying to make up for lost time after Sputnik I, the U.S. has put five satellites into orbit (Explorers I, III and IV, Vanguard, Atlas); fired two near-miss lunar probes (Pioneers I and III); started on an array of other satellite or space-probe projects; let development contracts with the Rocketdyne Division of North American Aviation Inc. for space-rocket engines with thrusts of 1,000,000 lbs. or more; pushed a man-in-space undertaking, Project Mercury, that is scheduled for announcement this month. But despite the flurry of projects, the U.S. has made disappointingly little progress...
...potency level of his laboratory brand. But Dr. Salk also conceded defects in the design of the vaccine itself. It contains three strains of polio virus for the three broad types that can independently cause disease- Mahoney for Type I, MEF-1 for Type II. and Saukett for Type III. About 80% of paralytic polio used to be caused by Type I strains; of the balance, Type III caused slightly more than half, leaving Type II as the least dangerous. But it is against Type II disease that the vaccine has proved most effective-it has almost disappeared in four...
...overall aim was good. U.S.'s Pioneer III deviated from its planned course by 3.5°. If it had reached the moon's orbit, it would have missed the moon by about 14,590 miles. The Russian miss (4,660 miles) was an error of only slightly more than...
Ever since the Russians launched their Sputnik III on May 15, 1958, rocket experts have known that they had the potential ability to toss a good-sized bird out of the earth's gravitational field. To put a satellite on a nearby orbit around the earth takes only about 25% less speed than the escape velocity (25,000 m.p.h.) that will free it from the earth. All the Russians needed to do was to increase slightly the power of Sputnik Ill's launching rockets or to reduce its final weight. U.S. failure to reach the moon was mainly...
