Corner Satellite. A more ambitious NACA satellite is made of the same aluminized film and weighs only 8.7 lbs. When inflated by a ½-lb. bottle of gas, it erects into a "corner reflector" 12 ft. in diameter...
...shot away from the earth at escape velocity (25,000 m.p.h.), a cheap 8.7-lb. corner reflector can be followed far into space. It can be watched by radar, says the NACA, as it circles the moon and heads back to earth. Its behavior will check the calculations of astronavigators and explore the spaceways for vehicles of the future, carrying instruments...
...near Washington, D.C. In daytime the signal reflects strongly from the ionosphere, but at night the ionosphere is less effective, so the signal gets much weaker. When a small meteor streaks across the sky, it leaves behind it a trail of ionized air that acts as a small reflector. The ionized air increases the strength of the Washington time signals for a couple of seconds...
...working part of the telescope is a parabolic reflector 250 ft. in diameter, surfaced with accurately curved steel plates and weighing 750 tons. Supported by two towers 185 ft. high, it pivots 360° on massive racks taken from turrets of dismantled battleships. The towers stand on twelve four-wheeled trucks that turn around a circle of railroad track. The combined motions of pivoting and turning allow the great reflector to point to any part...
