...Room. The U.S. unit that found the going toughest was the 2nd Brigade of the 25th Infantry Division, newly arrived from Hawaii. Assigned to the Cu Chi plain 20 miles northwest of Saigon, the brigade found itself encamped atop a veritable anthill of Viet Cong tunnels, in choking grey dust sometimes two feet deep. Enemy snipers and 60-and 81-mm. mortar crews penned the 4,000 men of the 2nd inside a perimeter only a mile long and 4,000 ft. wide-normally base-camp elbow room for only an 800-man battalion. Passage in and out was safe...
Meteor Bombardment. The Russians confirmed that Luna 9 had found no dust on the moon. Instead, it hit a surface that consisted of hard, porous, volcanic soil formed from lava that had crumbled during billions of years of drastic temperature changes and bombardment by meteors and solar particles. Inhospitable as it is, such a surface could probably bear the weight of both heavy space vehicles and men. The major obstacle remaining before man can fly to the moon, concluded Soviet Academy of Sciences President Mstislav Keldysh, "is the problem of returning a cosmonaut to earth. I think it is easier...
Though Luna 9 successfully disposed of the hypothetical thick layers of 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...
...born restless," writes Parks, and he tried everything. In 1937, after seeing a collection of dust-bowl pictures by Carl Mydans, Walker Evans and Ben Shahn (who in those days was a photographer as well as a painter), Parks decided to try photography. He hustled to a downtown Seattle hock shop, bought a $12.50 Voigtlander camera, spent half an hour learning how to use the thing, then began shooting everything that crossed his path. So intent was he that he fell into Puget Sound while trying to photograph sea gulls...
Even more significant, the pictures showed no evidence of the thick and treacherous layer of dust that many astronomers and physicists have predicted might envelop vehicles landing on the moon's surface. Said Astronomer Kui per, who at times during the past several years has stood nearly alone in insisting that there is little or no lunar dust: "There was never any basis for believing it anyway, but the idea seemed to fascinate people in the same way as flying saucers." The surface of the Ocean of Storms, Kuiper said, seemed to have been formed by lava flow during...
