...attempt to determine whether organic molecules can form on other planets, scientists at Ponnamperuma's Laboratory of Chemical Evolution filled a container with gases like those in the atmosphere of Jupiter. Then, to simulate sunlight and Jovian lightning flashes, they exposed the gases to ultraviolet light and shot electric discharges through them. The brown and yellow hues of the organic compounds that formed in the container closely resemble those in the spectacular pictures of the Jupiter clouds taken by the Voyager 1 and 2 spacecraft, which flew by the planet earlier this year. This finding strongly suggests that organic...
...March another unmanned space craft called Voyager 1, traveling still farther afield, sped past giant Jupiter and its moons. From half a billion miles away, the computer-controlled robot radioed starlingly clear color pictures of the banded Jlanet and its satellites, including briliantly hued closeups of the stormy Jovian Great Red Spot that would not look out of place in a gallery of modern art. It also sent back new data about Jupiter's Jovian radiation fields and found a "hot spot" of plasma, whose temperatures reach 300 million to 400 million degrees C. It even discovered a thin...
Last week another automatic spacecraft named Voyager 2 picked up where its twin left off. Programmed by controllers at Caltech's Jet Propulsion Laboratory in Pasadena to fill in gaps left by the first flyby, Voyager 2 did its closest reconnoitering of the larger Jovian moons on its approach to Jupiter rather than on its way beyond it, as Voyager 1 had done. That gave scientists at J.P.L. a totally different perspective on these little worlds...
...latest flood of information from these Jovian satellites would have thoroughly awed the great Italian Scientist Galileo, who discovered them 369 years ago. Moving at speeds approaching 45,000 m.p.h., the 1,800-lb. spacecraft swept by Callisto, the oldest, outermost and apparently smoothest of the Galilean moons...
...budgets and technical mishaps, the space program survives. Indeed, it shows definite signs of increasing its slackened pace. This very week Voyager 2, a brilliantly conceived robot, is streaking past Jupiter, directing its color cameras and multiple instruments at the giant, banded planet and its great moons. Seized by Jovian gravity, Voyager 2 will swing around the planet and then fly off in the cosmic wake of its twin, Voyager 1, for a reconnaissance of Saturn in August...
