...evidence is overwhelming," said Director Allen Dulles of the Central Intelligence Agency, "that the Soviets intend to use nuclear blackmail as a major weapon to promote their objectives-namely, to spread Communism through out the world." Dulles' rare public statement was read to reporters as he emerged from a closed-door session with 45 U.S. Governors, meeting last week in San Juan, Puerto Rico. Behind the doors Dulles provided some classified details to back up the most serious proposal before the annual Governors' conference: U.S. Governors should take the lead in getting their citizens to build nuclear-fallout...
...almost exactly into its planned path, first reached its record apogee some 26,400 miles straight out into space from the Cape of Good Hope, its perigee a narrow 157 miles over Singapore. With so great a range of altitude, it will pierce both of the newly discovered Van Allen radiation belts (TIME. May 12, 1958 et seq.), collect comprehensive data on phenomena ranging from the earth's ionosphere to cosmic dust...
...1/161n. aluminum skin shrouds the most intricate and talented collection of scientific instruments yet sent into space -all in a 29-in. by 26-in. ball that moves through its complete orbit once every twelve hours. One hoped-for result is the first relatively detailed map of the Van Allen belts, which present a formidable barrier to interplanetary flight. Previous earth satellites have not gone high enough to examine the enormous breadth of the Van Allen radiation. Pioneer IV obtained valuable information, but made only one trip through the belts before falling into orbit around the sun. Several devices...
...register intense blasts of radiation. Study of the instrument packages at the University of Minnesota showed that the radiation was made of speeding protons from the sun. The radiation was about 1,000 times as intense as the cosmic rays that normally come from space. Unlike the Van Allen radiation, which is made of solar protons that have been trapped by the earth's magnetic field and forced to zigzag around the earth, the balloon-detected particles came directly from the sun, crashing into the earth's atmosphere with energies between no million and 120 million electron-volts...
...Polar Exits. When the doughnut-shaped Van Allen radiation belts were discovered (TIME, May 12. 1958), optimists predicted that unshielded space vehicles could avoid them by taking off on space voyages by way of the "holes"' over the polar regions. But the deadly, invisible streams of the new-found radiation lash through the polar holes, as well as through the whole solar system. Space vehicles making the short run to the moon may be able to pick quiet intervals between the flares, but voyages to Mars or Venus will take several months. During this considerable period a flare...
