...accident; several bones were broken, and the baby was lost. "She was a real tiger and a real fighter," John recalls, but her struggle to recover ended abruptly during surgery to remove the fetus. Oxygen was inadvertently cut off, causing irreversible brain damage. Nancy Jobes has been in a coma ever since, sustained by a feeding tube in a New Jersey nursing home. John, together with Nancy's parents and siblings, wants to have the feeding tube removed, but faces a battery of legal and medical obstacles. "There is no quality of life," he insists. "Nancy would not want...
...Soviets were justifiably proud. Their spacecraft -- designed, built and equipped under their supervision by scientists from ten nations -- had become the first man-made object to record close-up views of a comet's coma and nucleus, and send the images and other data back to earth.* It also served as the advance guard for four other craft -- the Soviet Vega 2, the Japanese Suisei and Sakigake, and the European Space Agency's Giotto -- that were to sweep by Halley's in the following week...
...comet), the spacecraft's TV cameras shot some 500 pictures in about three hours. Transmitted across 109 million miles of space, each picture took nine minutes to arrive in Moscow, where it was colored by computer to emphasize differences in brightness. The first images showed only the coma, the great cloud of gas and dust surrounding the nucleus, as a fuzzy, violet-fringed, blue-green ball with a yellow center. But in images that Vega 1 shot when only 5,600 miles from Halley's, a dark red area with rather distinct boundaries appeared near the center of the image...
...fact, Halley's spectacular show did not go entirely unobserved. Last week scientists at NASA's Ames Research Center in California proudly displayed computercolored ultraviolet images of Halley's hydrogen coma as it appeared between Feb. 2 and 5, and described the changes in the comet during its most active period...
Pioneer will continue to observe Halley's, measuring water loss and looking for oxygen, carbon, sulfur and other elements in the coma's gases, until March 6, when the sun will begin blocking the Venusian view of the comet. On that day, however, the first of an international flotilla of spacecraft will take over Halley's vigil. The Soviet probe Vega 1 will fly through the coma, passing within 6,000 miles of the nucleus. It will be followed by another Soviet craft, two Japanese probes, and the European Space Agency's Giotto, which will make the most daring pass...
