This personal world of housecalls and stethoscopes in black bags is gone. "Instead of spending forty-five minutes listening to the chest and palpating the abdomen, the doctor can sign a slip which sends the patient off to the X-ray department for a CT scan," Thomas observes, continuing later that "the doctor can set himself, if he likes, at a distance, remote from the patient and the family, never touching anyone beyond a perfunctory handshake as the first and only contact...
Landsat's electronic eyes scan patches of the earth's surface 115 miles square, one after another. (It takes 30,000 images to show the entire planet.) The satellite views each square in different colors, some seven different wave lengths in all, including several "invisible" infra-red frequencies. The images are sent as a stream of radio signals to earth stations, where they are assembled by a computer into full pictures. In many instances, scientists arbitrarily choose the final colors to represent a specific condition; for example, blazing red might indicate healthy crops, while black would mean ailing...
...Columbia in November 1981. That mission had to be cut from 124 hr. to 54 hr. because of a faulty fuel cell, but before aborting the flight, the astronauts were able to complete an experiment with the ship's radar equipment. They took a 50-km-wide scan of the Sahara from the shuttle. Radar waves generally penetrate only a few centimeters of the earth, since the beams are dissipated by moisture in the surface of land. But in the dry Sahara, the radar waves were able to pierce to depths of five meters, reflecting from bedrock...
...every spot on earth once every 48 hr. in daylight. Big Bird sends back TV images and provides high-resolution photographs, which are ejected in parachute-equipped canisters that can be hooked in mid-air by recovery planes. Both the U.S. and the Soviet Union have satellites that can scan the earth with radar beams. One objective: to track naval vessels...
...child, from the driver's-side door (leading to speculation, eventually squelched, that the underage and unlicensed Stéphanie had been driving). Firemen extricated Princess Grace. The first confusing bulletins from the palace spoke only of a broken leg, but she never regained consciousness, and a brain scan showed irreparable damage from the stroke and her injuries. She died the next day, at 52, after Rainier and their older children, Princess Caroline, 25, and Prince Albert, 24, agreed to the removal of a life-support system. At week's end Stéphanie remained hospitalized with...
