Actual production was in the hands of husky young (31) George Ludwig, a graduate student who has proved himself a mechanical genius in the painstaking new art of space instrumentation. Each ounce counts, because it costs many thousands of dollars to put each ounce into orbit. The tiny, buglike components must stand enormous g forces, vibration and spin, survive violent changes of temperature...
Mysterious Silence. On Jan. 31, 1958, a Jupiter-C, fired from Cape Canaveral, put Explorer I into a fine orbit. With two massive Sputniks to compete with, the U.S. pinned its hopes for outdoing the Russians on the superiority of Van Allen's instruments...
Next: Venus. Like most other scientists, Van Allen is in no hurry to put a man into space. "A man is a fabulous nuisance in space right now," he says. "He's not worth all the cost of putting him up there and keeping him comfortable and working." Instruments are lighter, tougher and less demanding, are sensitive to many things that human senses ignore. They already have memories (tape recorders), and they can carry computers that will permit them to make judgments. An instrument-manned Venus probe should be able to make observations and adjust its course by firing...
GETTING information from a satellite is tricky business. "If you want to measure the temperature up there," says Van Allen, "you can't put a mercury thermometer in your bird. You have to read temperature as an electrical signal." This is done with a tiny "thermistor," whose resistance to current put out by the satellite's batteries varies with temperature. The change affects the frequency of the electronic signal sent out by the satellite's transmitter, thus reporting the temperature to the ground...
Last week restless Bill Lear was off to something new, as usual. In West Los Angeles he opened a $250,000 laboratory to put his company into solid-state physics in his search for new products. Among far-out fields to be studied: microcircuitry (e.g., reducing the chassis of a satellite television unit to a few cubic inches) and electroluminescence (e.g., picturing all of a plane's instrument readings on a cockpit window so the pilot will not have to glance away even when landing or taking off). While moving farther into the wild blue yonder, he is also...
