...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...
Died. Maurice Neville Hill, 46, British oceanographer, a Cambridge University professor who in 1 947 devised a method of determining the thickness of the earth's crust by measuring the seismic effect of explosions in the water, thereafter led a series of expeditions that in 1953 placed the thickness of the crust beneath the Atlantic at an average three miles; of self-inflicted gunshot wounds; in Cambridge...
Tombaugh believes that the canals are faults or fractures, several miles wide, in the Martian crust. Their darkening and fading may be caused, he says, by the intermittent escape of hot gases that melt a thin layer of frost and vegetation. The oases where the faults intersect, he speculates, are probably impact craters where moisture gathers and promotes the growth of moss or lichenlike plants hardy enough to withstand the harsh Martian climate...
