Writing in Nature, Physicist Clyde Cowan of Catholic University of America, along with Geophysicist Chandra Atluri and Nobel Prizewinning Chemist Willard Libby of U.C.L.A., offer the most ingenious theory so far. After disposing of previous guesses (If it was a meteor, where is the crater? If it was a comet, why was it not seen approaching?), Libby & Co. suggest that what caused the big bang may well have been a hunk of antimatter that must have wandered into the solar system from some distant galaxy...
...best Ranger photographs, explained O'Keefe in teh magazine Science, show a region covered by broad, light-colored streaks radiating from the craters Copernicus and Tycho. These rays are believed to be dust and fragments tossed out by teh meteor impacts that blasted the two craters, and since they lie on top of most other lunar features, they are listed among the youngest parts of the moonscape. But O'Keefe also found a conspicuous black mark showing starkly against the lighter background of one of Tycho's rays. The ray had not dusted the mark with light...
...wreck is credibly contrived. While circling Mars on a reconnaissance mission, the astronaut (Paul Mantee) changes course to avoid a meteor and so falls deep into the planet's field of force. To escape eventual incineration, he ejects his capsule and plunges down into a scene of staring desolation. Hell-hot by day and by night pole-cold, the Mars of the movie supports no visible life and very little atmosphere. However, the astronaut does not expect to be there very long. From the wreck of his capsule he rescues food for 60 days, water for five days, oxygen...
...that attempts to land on them. Dr. Kuiper thinks that regions splashed with rocks tossed out of big craters should be studiously avoided, but other parts of the lunar plains are probably smooth enough for landing. An encouraging sign is the comparative scarcity of small primary craters blasted by meteor impacts...
...tektites found in Canada and the U.S. All proved to be 34 million years old. Impactites from the Clearwater Lake crater in northern Quebec and from far-off Libya have the same age. Other tests show that tektites found in Czechoslovakia pair up with impactites from an ancient meteor crater in Germany. Both are 15 million years old. An impactite from Tasmania is 700,000 years old, the same age as tektites found in Australia, Indonesia and Southeast Asia...
