HUMAN SPIES FOR RUSSIA CHEAPER THAN SATELLITES — It would be cheaper for Russia to spy on the U.S. through normal channels than by putting a reconnaissance satellite into orbit…. Russian agents in the U.S. can glean vast amounts of solid information merely by reading several major metropolitan daily newspapers…. The Department of Defense thus takes the attitude that the object recently found circling the earth in a polar orbit probably was the last stage of Russia’s Lunik III and not a reconnaissance satellite…. Spy satellites, when perfected, probably will be able to gather information by watching or by listening. They can watch by using either photographic or infrared equipment. They can listen with sensitive radios.
