...hands full with more down-to-earth problems last week, but even President Carter took time out to watch an otherworldly show as the Voyager 1 spacecraft made its closest approach to the giant planet Jupiter. Coming within 278,000 km (172,400 miles) of the swirling Jovian cloud tops, the robot survived intense radiation, peered deep into the planet's storm-tossed cloud cover, provided startling views of the larger Jovian moons and, most surprising of all, revealed the presence of a thin, flat ring around the great planet. Said University of Arizona Astronomer Bradford Smith...
...tense hours, during which Voyager sent back enough data to fill up miles of magnetic tape and keep scientists busy for years ahead. But Voyager has already opened up new worlds for them. Ablaze with colors of every shade and hue, speckled with strange, often puzzling features, the Jovian moons prompted oohs and aahs from even the most seasoned scientists...
Last week, after a journey of 18 months, a tiny visitor from earth streaked precariously close to the giant of the solar system, penetrating deep into Jupiter's powerful magnetic field and coming within 278,000 km (172,400 miles) of the Jovian cloud tops. Back at Caltech's Jet Propulsion Lab, controllers waited breathlessly to see whether the plucky robot would survive that dangerous encounter. But even before Voyager 1 made its closest approach on Monday, the 826 kg (1,820 lb.) unmanned spacecraft sent home a trove of new findings about Jupiter, including evidence that...
Whether or not this technological gambit succeeds, the $400 million project has already provided rich scientific dividends. Even before the drum-shaped spacecraft's first brush with the so-called bow shock region, where the Jovian magnetic field traps the solar wind, Voyager's sensitive instruments picked up a bewildering jet stream of frozen ammonia apparently traveling at 560 km (350 miles) per hour above the planet's clouds. Voyager also discovered a dazzling, doughnut-shaped cloud of electrically charged particles that formed displays similar to the earth's northern lights...
...yellowish sodium cloud cover and a strange surface chemistry that may be a consequence of intense radiation bombardment. On its closest approach, Voyager will come within 18,800 km (11,650 miles) of this mysterious moon. Then, as Voyager sweeps away, its instruments will get glimpses of the other Jovian moons, perhaps even a tiny 14th moon, which was spotted several years...
