...years, ever since the earliest days of the cold war, each American President, each Kremlin leader, has felt compelled to counter every move by a countermove, every new weapon with a newer weapon, every show of strength with a greater show of strength. The two hands that control the planet's survival may clasp in a show of summit cordiality, but measurable progress to curtail their nuclear arsenals requires far, far more than ceremonial displays of goodwill...
...Saturn in 1981, sending back spectacular pictures and mountains of data. Last week, still in good health after more than eight years in the void, Voyager 2 had closed to within 46 million miles of Uranus, its next target. The spacecraft's early shots of the mysterious planet, which is four times as large as the earth, were transmitted across 1.8 billion miles of space to the Jet Propulsion Laboratory in Pasadena, Calif. They depicted Uranus as a fuzzy blue-green ball, showed its five known moons and barely discerned the outermost of its dark rings...
Although light reaching the planet from the sun is only a quarter as bright as it was near Saturn, scientists expect Voyager's cameras (as well as its other instruments) to reveal considerably more detail as the spacecraft draws closer to Uranus and finally swoops to within 66,000 miles of its surface on Jan. 24. Voyager's odyssey will not end there. Accelerated to 45,000 m.p.h. and rerouted by Uranian gravity, it will soar still farther away from the sun, encounter Neptune in 1989, then head out of the solar system on an endless journey to the stars...
...Editors: We should pause during our excitement over the return of Halley's comet [SCIENCE, Dec. 16] to contemplate the observations the comet could make about us and our planet. Since the Wright brothers' flight in 1903, we have left the earth and visited the moon. We have sent probes to other planets and to the far reaches of our solar system. We have stopped being earthbound and have ventured out to greet the comet. In the next 75 years, will we still be waiting for Halley's comet to come to us, or will we be chasing it? John...
...looking over the year in pictures [IMAGES, Dec. 30], I noticed that you did not include any photographs of the astronauts in space. You often feature forces that divide mankind. It would be useful to show us a picture reminding us that we all live on the same small planet. Gregory N. Papadatos Fort Ord, Calif...
