Caveat to Cheaters. But what might be the effect upon today's U.S. nuclear superiority of Russian treaty cheating? McNamara argued that the U.S. could almost certainly detect any Russian nuclear tests of a size worth conducting. He conceded that the Soviets might get away with a test in deep space-20 million or more miles away from the earth -but such tests "would involve years of preparation, plus several months to a year of actual execution, and they could cost hundreds of millions of dollars per successful experiment." Anyway, he said, the U.S. plans to launch within...
...help lawyers assess prospective jurors, a research team working under the auspices of New Jersey's Fairleigh Dickinson University persuaded some 500 persons of varied backgrounds to take an elaborate test designed to reveal prejudices that might affect their judgment as jurors. The test was set up to detect both "overt" and "covert" prejudices. The findings, released this week, include a lot of surprises about who is, or is not, biased toward whom...
Scientists studying the provisions of the nuclear test ban treaty have voiced few fears about their ability to detect most violations-either under water or in the atmosphere. But what about the farther reaches of space? On that problem, even wishful thinkers have their doubts. "What if the Russians run a clandestine test behind the moon?" they ask. "Or do it forty million miles away from the earth...
These are not idle fears, but U.S. nuclear authorities have not been idle about them either. For five years the Atomic Energy Commission has anxiously been pushing a project code-named Vela-Hotel, designed to detect nuclear explosions in space. Last week the Hotelmen delivered their first package of special instruments. Before the end of 1963, similar instrument packages are scheduled to take the long rocket-ride into space on Air Force-launched satellites...
Delayed Debris. Easiest to detect-provided the proper instruments are orbiting in space-are the soft X rays; they are by far the largest product of the explosion. The Vela-Hotel instrument package is expected to detect soft X rays from a one megaton explosion 200 million miles away from the earth and distinguish them from X rays from solar flares and other natural sources. Some instruments are also sensitive to gamma rays and neutrons...
