...That close flyby, well within the orbit of Mercury, should make for a dazzling interaction between sun and comet. Perhaps most important of all, astronomers describe it as a "dirty" comet, one with an outer layer of dust that has probably never been stripped off by solar heating. That layer may prevent the comet from becoming as bright as originally predicted. But it also means that Kohoutek may be a "virgin," making its very first visit to the hot inner sanctum near the sun. That will give scientists an opportunity to study at close hand the structure of material that...
...comet's composition and structure. At least five sounding rockets and two balloons will be launched to view Kohoutek. The comet will also be chased by two highflying, instrument-crammed jets. Other information will be gathered by Copernicus, NASA'S orbiting astronomical observatory, and OSO7 (for Orbiting Solar Observatory). The Venus-and Mercury-bound Mariner 10 may be used to take high-resolution TV pictures of the comet, while either Pioneer 6 or Pioneer 8, both of which are orbiting the sun, try to determine the density of the comet's tail by probing it with radio...
Scorched Planet. Kohoutek's arrival comes at a remarkable stage in man's exploration of the solar system. Scientists are still sifting through the mass of lunar measurements, pictures and rocks brought back to earth by the Apollo astronauts. From the data gathered by Russia's Venera 7 and 8 landers, America's Mariner 2 and 5 flybys, and radar observations by the Mojave telescope, astronomers can now describe in some detail the hellish surface temperature (900°F.), cratered topography and atmospheric conditions of cloud-shrouded Venus. Using the startlingly good pictures transmitted by Mariner...
Still another solar-system explorer, Pioneer 10, last week briefly eclipsed even the growing excitement over Comet Kohoutek. Completing a 21-month voyage across the bleak, cold reaches of more than half a billion miles of space, the 570-lb. robot gave man his first close-up look at the giant planet Jupiter. After penetrating intense radiation belts that pack radiation dosages at least 1,000 times the level regarded as lethal for humans, Pioneer passed just 81,000 miles above the multicolored Jovian cloud tops, took color pictures, gathered oth er data and then was hurled by the enormous...
...later, or Skylab had been launched only slightly earlier, the space station would not have been available for the important observations. Says Astronaut-Scientist Karl Henize: "All through the space program, we've been looking for a Rosetta stone-what is the primordial material out of which the solar system is made? We looked for it on the moon and we didn't find it; we found other things instead. Now we're down to our last chance-the comets. It's something of a miracle that we have Skylab up there just when a bright...
