When Echo first took to space on Aug. 12, it was as round and polished as a giant ball bearing, its aluminized Mylar film kept tightly inflated by 20 Ibs. of vaporized anthraquinone, a normally solid organic chemical. When its 100-ft. sphere moved on its orbit 1,000 miles away from the surface of the earth, it covered about one-tenth the angle of the planet Venus at 40 million miles, but it did not show as a disk even in a powerful telescope. The sun reflecting on its spherical surface showed as a mathematical point, as stars...
When the satellite finally reaches space it may be followed on its orbit by a frail, light, short-lived companion. Developed by William J. O'Sullivan Jr. (following a long-discussed idea), the inflated sub-satellite is a balloon of Mylar plastic .0025 in. thick covered with an aluminum film .0006 in. thick. When released from the third-stage rocket, it will weigh 10½ oz. complete and look like a wad of aluminum foil. A small capsule of compressed dry nitrogen will expand the plastic to a sphere 20 in. in diameter, which will follow at first...
...shopper's eye. The lures have to be strong; researchers at Du Pont calculate that a package in a supermarket has as little as 20 seconds to stop a passing customer. Among the stoppers: ¶Martinis and Manhattans sealed in packages of Du Font's transparent Mylar...

...Round Coverage. Du Pont Co. announced it will soon build a plant to produce Mylar, a new Cellophane-like film which it claims is two to eight times stronger than other films and unaffected by wide-range temperature changes. Mylar will be chiefly used as an electrical insulator, in packaging, and as a magnetic recording tape. Price: $3 a lb. v. 55? for Cellophane...
