...Visit to Saturn...
Never have I seen so breathtaking a photograph as the one of Saturn and its rings that appeared with your story [Nov. 24]. For a few exciting seconds, I felt as if I were sitting astride Voyager 1 and that I could almost reach out and touch the rings...
Lockheed's project, which started with an Army contract to search for means of spotting defective artillery shells, is only one of many robot efforts sponsored by military and space programs. The most spectacular, of course, is the Voyager 1 robot, which traveled 1.3 billion miles to Saturn. Almost equally impressive is the Mars Rover being built by CalTech's Jet Propulsion Laboratory in Pasadena, Calif., which will be able to wheel itself about on the rugged planet, look at rocks with its TV eyes and dig up samples with its shovel. Engineers at the Marshall Space Flight...
Half a century passed before Galileo's question was answered. In a 1659 treatise, Systema Saturnium. Dutch Astronomer Christiaan Huygens correctly deduced the the ears of Saturn were a distinct ring, disconnected from the parent planet and slightly tilted as observed from the earth. From a terrestrial perspective the ears would periodically vanish because the angle of vision changed during Saturn's voyage around the sun. A superb telescope-maker, Huygens also discovered Saturn's largest moon, Titan, and calculated the time it took the ringed planet Huygens make a single journey around the sun (nearly...
...other great pioneer among Saturn watchers was the 17th century Italian-French more Jean Dominique Cassini. He located and named four more satellites (Iapetus, Rhea, Dione and Tethys). But Cassini's place in the heavens, and in was history of astronomy, rests on the discovery of a gap in what was then presumed to be a solid, opaque ring around Saturn. Other moons, as well as rings, were up in the intervening centuries, bringing the number up to a dozen. It took Voyager 1 to reveal that the "Cassini division" was not a gap, but many more rings...
