...satellites put into orbit around the earth, the U.S. had come a long way since the first Soviet Sputniks jolted the nation's confidence in the fall of 1957. And last week came the news of two more big strides in space-military technology: a 142-lb. paddle-wheel satellite that uses solar energy to power its transmitters and a monitoring system capable of detecting and tracking missile and rocket firings far beyond the range of the keenest-eyed radar (see SCIENCE...
...keep the interior of the paddle-wheel satellite at an even temperature range as it passes from the cool shadow of the earth into the blazing heat of the naked sun, Explorer VI has on its outer skin a patch of black-carbon paint. A thermostat actuates a small shield that alternately covers and uncovers the patch as heat requirements dictate. Since the satellite uses electricity much faster than the paddle wheels can make it signals from the earth periodically shut of the largest of Explorer VI's three radio transmitters. A memory device called Telebit takes over, stores...
...Einstein's theory on the curvature of space to the question whether man can really get past the Van Allen radiation belts by entering space above the earth's poles. At week's end a spokesman for the National Aeronautics and Space Administration reported: "The paddle wheel is doing well. It is converting solar energy into electrical energy. The signals are coming in loud and clear." If its perigee edges in too close to the earth, the paddle-wheel satellite still has a 5-lb. kick rocket that can be fired to elongate its orbit; last week...
...delegates (representing 76 Reformed and Presbyterian church bodies with more than 45 million members) shifted their interest from theology to a theologian. In the limelight: Czechoslovakia's Dr. Joseph Hromadka, 70, wartime lecturer at Princeton, dean of Prague's Communist-controlled Amos Comenius Theological Faculty, a wheel in the World Council of Churches and a vice president of the Presbyterian Alliance. Hromadka has attended every postwar ecumenical congress, has raised serious problems about how Western Christians are to regard their brethren in Iron Curtain countries...
Electronic Watch. Bulova Watch Co. will put an electronic watch on sale next year. The watch will use transistors to eliminate mainspring and balance wheel (electric watches do away only with the mainspring), will weigh no more than a regular wristwatch...
