...Chick's Heartbeat. NASA Consultant Quentin L. Hartwig reported a fascinating example of the application of space research to earth-bound medicine. To record the impact of a speck of interplanetary dust on a man or vehicle in space, Engineer Vernon Rogallo devised an instrument so sensitive that it registered the force of a single grain of salt dropped less than one-half of an inch. Then, at the NASA Ames research center in California, Rogallo overheard a cafeteria conversation between two biologists: How could they record the heartbeat of a six-day-old chick embryo without piercing...
...watt beacons, visible five miles in daylight and twelve at night, light up either manually or automatically to signal break-ins or holdups. Within 21 minutes at most, the sheriff's men expect to swoop down on the scene, spot suspects with powerful floodlights, direct approaching earth-bound cops or, if necessary, land to give assistance...
When the full set of Martian pictures taken by the spaceship Mariner IV was released last week, Mariner's earth-bound master, Physicist William H. Pickering, had the White House itself as his gallery. President Johnson was on hand to present awards to Pickering and two other Mariner scientists.* For cautious experts, the best of the photographs neither proved nor precluded the possible existence of life on Mars, although the planet's rugged terrain seemed hardly hospitable enough for the hardiest of bacteria. The pictures were clearer and sharper than anyone had expected. At least one of them...
...that either heart attacks or other seizures are more common among the new flying fraternity than more earth-bound men. But they are more disastrous, and the time may come when elementary piloting is taught in every U.S. high school (as car driving is in many states). In the meantime, such training is already under way for members of a group that feels the need for it: private-flyers' wives...
Ever since Galileo taught them to scan the skies with a telescope, astronomers have studied the sun with particular interest. It is the earth's own star, and to earth-bound viewers it glitters with 10 billion times the brightness of any other celestial body. Everything significant that happens on the sun-the emergence of solar flares, for example-signals some effect on the earth's atmosphere...
