...changes most principals mentioned: stiffening of math and science courses, special programs for gifted students. Some of the schoolmen are scrambling hard to reach a now fashionable orbit: "We are going to employ a more competent science instructor...
...satellites, which he prefers to call a sub-satellite, is so light that it can be carried almost as an afterthought by any orbit-bound rocket. It is a balloon of plastic film .00025 in. thick, bonded to aluminum foil .0005 in. thick and packed in a doughnut-shaped container. To inflate the balloon, O'Sullivan provides a capsule of nitrogen gas at 2,000 Ibs. pressure per square inch. The whole apparatus weighs only...
...launching pad at Cape Canaveral one afternoon last week thundered an Army Jupiter-C rocket. Seven minutes later, the rocket popped a satellite into orbit. What was even more remarkable than this space-age achievement was the fact that the world accepted the news of a third U.S. orbiting moon with a great deal less flutter than that accorded the winners of Hollywood's Academy Awards (see CINEMA...
...similar to Explorer I, fired Jan. 31, and identical to Explorer II, which miscarried and disappeared after its successful launching March 5. Explorer III, weighing 31 Ibs., carried a special tape recorder that would enable scientists to measure cosmic rays more efficiently (see SCIENCE). As it turned out. its orbit, coursing an ellipse from 110 miles at its perigee to 1,735 miles at apogee at a top speed of 18,850 m.p.h.. was less than Army scientists had hoped for-and as much as 700 miles inside the Navy's grapefruit-sized Vanguard. Early calculations showed that...
Physicist DuBridge is all for unmanned satellites to study the earth and nearby space, and perhaps to orbit the moon. "A scientist," he said, "cannot help but be excited by this prospect. It opens up wholly new areas of exploration. A whole book could be written about what the astronomers would like to do with a telescope above the atmosphere...
