Although the theory remains vague, the potential uses of Nitinol alloys seem apparent enough. Goodyear Aerospace Corp. has already demonstrated that a complex Nitinol satellite antenna crumpled up into a small ball before launching can be restored to its original form simply by heating it in space. The same procedure has been proposed for orbiting a radio telescope as large as a mile in diameter. "All we have to do," says Buehler, "is put these large structures into suitably compact packages on the ground and then kick them into space and let them unfold from solar heating...
...General Motors, Pontiac will feature a 1969 Grand Prix boasting the longest hood in the industry and superthin wires across the windshield to take the place of the traditional radio antenna that usually rises from a fender. The big Oldsmobiles are in for the biggest changes. They will remain big, but their pudgy '68 bodies will give way to more severe trim and styling...
...Entomologist Philip Callahan, of the Department of Agriculture, reports on delicate experiments with which he answered the question. Callahan caught some giant cecropia moths, which live in the woods, studied them under a binocular microscope and decided that it was tiny spikes at the base of their delicate, fernlike antennae that reacted to strong light. To check his theory, he blacked out the moths' eyes, painted each antenna black, except for the tips of the spikes, and ran minuscule wires into the main antennal nerves. Then he began subjecting them to light of varying intensity...
Their rough but unique closeup of Venus stems from 17 radar probes with NASA's 210-ft. dish antenna at Goldstone, Calif., last summer. At that time Venus was only 26 million miles from the earth. Since then, the scientists have been "drawing" a map by feeding their electronic findings into a computer. The result shows three blotches of extremely rough terrain, which Goldstein presumes are mountains, moonlike craters or fields of boulders...
Mapping the Milky Way. This week the satellite will receive a radio command from earth and begin to unfurl its giant antenna system. Carried as flat ribbons of silver-plated copper alloy coiled on spools within the satellite, the tubular legs will be formed as the outer edges of the unwinding ribbons curl towards each other and meet. Tiny tabs along the edges of the ribbon will hook together as the tubeb forms, adding rigidity. At first, the antenna legs will be extended only 358 ft. from the craft, to test their stability. Then they will grow to their full...
