...thin, high, outer fringe of the atmosphere, the Fort Monmouth men explained, the atoms of gas are ionized by solar ultraviolet light into positively charged nuclei and negative electrons. Theory suggested that at a certain altitude above the earth this charged plasma should have a sort of elasticity that would permit hydromagnetic waves to pass along it, rather like mechanical waves traveling along a coil spring. The Fort Monmouth scientists found that the Argus explosions started just such waves in a layer of plasma about 1,500 miles high. The waves were about 1,000 miles long, and they traveled...
Next day the Russians released a picture of Lunik III and a fairly detailed explanation of how it took its epoch-making pictures. Lunik III, a notably sophisticated mechanism, proved to be a top-shaped 614-lb. object incrusted with antennas and solar cells, and packed with instruments. As Lunik passed 4,000 miles below the moon's south side, the moon's gravitation tugged at it, pulling it upward (south to north) and behind the moon. This was as planned, the Russians said, so that when Lunik III returned to earth it would come closest...

...space (which is basic to weather forecasting), and carry out other experiments. The satellite is shaped like a gyroscope and is spun to keep it whirling cleanly instead of tumbling. It squeals like a bagpipe as it signals from two transmitters-one powered by a chemical battery, the other solar-powered and possibly could transmit for the expected life of the satellite-20 years. But, through a unique timing device, the radio will shut off after one year so as not to clutter the air waves. Explorer VII takes over from the Explorer VI paddlewheel (TIME, Aug. 17), whose solar...
