...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...
Sphere of Nothing. When the rocket reaches the orbit, the nitrogen inflates the balloon and pops it out of its container. When all the gas has left the capsule, the balloon is erected into a sphere 30 in. in diameter. The pressure inside it (.2 lb.) is enough to stretch the wrinkles out of the aluminum film and make it mirror smooth. After doing this job, the nitrogen escapes into the vacuum outside. O'Sullivan wants to get rid of it because the balloon may be punctured by a meteor, and a jet of gas escaping from it might...
...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...
