...when Ikeya-Seki came within 45 million miles of the sun and heated up enough for its infra-red emissions to be picked up on earth. As the comet raced closer to the sun, its temperature climbed gradually, reaching 1,200° F. about 20 million miles from the solar surface. Then the comet's emissions were blotted out by the sun's own fierce radiation. On the return leg of its journey, Ikeya-Seki displayed identical temperature variations, dropping from 1,200° F. at 20 million miles to 700° F. at 45 million miles...
...Solar Heating. To Becklin and Westphal, this consistent temperature behavior suggests that the comet generated no heat, but was warmed entirely by solar radiation. Another set of observa tions seemed to bear them out: temperatures of the comet's head and tail were always identical. If the comet supplied some of its own heat, its head, or nucleus, should have been warmer...
...whet the appetite of astrophysicists, many of whom believe that the fiery-tailed bodies are well preserved condensations of the primordial matter from which the sun and planets were formed. If that is correct, a complete analysis of a comet might provide valuable information about the beginnings of the solar system. To obtain a sample for such a study, some scientists suggest, an unmanned spacecraft should be shot into the orbit of a regularly reappearing comet. The craft would rendezvous with the comet, land and scoop up some surface material. Then, after a brief, blazing ride through...
...that there is another universe "embed ded in the same space-time framework" as man's-only its time runs backward. Such a "Faustian"* universe, he says, would be unobservable by earthmen because Faustian matter would not in teract with normal matter; it would separate out into planets, solar systems and galaxies...
...boosters lofted the 850-lb. craft into a parking orbit, where it coasted for 28 minutes while ground computers honed its next course. Then, high above the Indian Ocean, the second-stage Agena engine reignited and kicked the orbiter into its precise moon-bound path. Two antennas and four solar-power panels snapped out, giving the space craft a windmill look. Guidance sensors aligned it with the sun; some six hours later, a star tracker began hunting for Canopus. When the sensor repeatedly failed to lock onto the guidance star, ground controllers made do by using the moon instead...
