Luna's gamma-ray measurements indicated that the moon has a crust some what similar to the earth's. The satellite also established for the first time that both the number of meteorite particles and the strength of the magnetic field in the vicinity of the moon are higher than in interplanetary space. It also discovered 70 to 100 times as many energetic electrons as are expected in outer space. Russian scientists attributed the electrons to the "earth's magnetic tail...
...somehow; occasionally just plain good luck comes along to give them a boost. A few years ago, feudal Libya was written off as a hopeless non-nation-until oil was found floating beneath the deserts. Barren Mauritania may yet bloom from the rich iron and phosphate deposits in its crust. Some unlikely nations have been struggling along for many years-little San Marino smack in the middle of Italy, Haiti and the Dominican Republic-and there is not much hope that their situation will improve. On the other hand, a minuscule country like Switzerland, divided into several parts by language...
...Viet Nam war is neither popular nor unpopular with most Americans. It is simply confusing. Nobody is better aware of that than Lyndon Johnson. Though the pollsters tell him that a substantial majority of Americans approve of his policies, he knows that he can rely only on a thin crust of active support; and a vocal opposition is constantly gnawing away at that crust. In large measure, the fault is his own, for he has never definitively explained the reasons, risks and alternatives involved in the American commitment to Viet Nam's struggle for independence...
...lunar dust, said University of Arizona Astronomer Gerard Kuiper, some parts of the moon could still present a hazard to landing spacecraft. Photographs from the U.S. Ranger 9 moon probe show that between 5% and 10% of the lunar surface is covered by depressions, apparently areas of thin crust that have sagged into caves or voids under the surface. Should a spacecraft land on such a crust, he believes, it might crash through into the cave below...
...Dusty Theory. Taken by a camera with a wide-angle lens from about 10 ft. above a porous, pumicelike surface, the pictures showed a barren, forbidding crust, littered with jagged rocks and tiny pebbles that the Russians later revealed were as small as 1 or 2 millimeters wide. The lunar view suggested to University of Arizona Astronomer Gerald Kuiper that Luna 9 was probably resting on the floor of a small crater, that the rocks were only about a foot high, and that the horizon in the picture was actually formed by the crater's rim, apparently less than...
