...surface. Recent observations, however, suggest that the moon has been a cold planet for so long that volcanic activity is not a satisfactory explanation of its topography. Instead, the belief is growing that its craters were torn out by meteorites, and that the plains are huge seas of dust...
Gold believes htat dust and debris from the crater-building explosions filled in most of the older craters on the moon's surface. Since there is neither wind nor rain on the moon, the dust would stay more or less where it settled except when agitated by thermal or electrical disturbances. If such is the case, says gold, the dust could "flow over the surface like a liquid, running down the sides of cold craters to fill in the bottoms." Gold therefore believes that the moon's vast plains are not exposed layers of lava but oceans...
...Midi observatory in the Pyrenees, measuring variations in the brightness of light on a selected section of the lunar flats. The amount of variation and polarization that occurs at different times of the lunar day will indicate whether the sun's rays are being scattered by tiny dust particles or by solid surface. "Within two or three months we should know definitely," says Professor Zdenek Kopal, who will take charge of the experiment. Meantime, says Cosmologist Gold, spaceship pilots are advised not to land on the lunar plains...
Borne on the winds that sweep out of Russia, radioactive dust from the Soviet Union's latest super H-bomb (TIME, Dec. 5) descended on its neighbors. The Dutch army reported a "high content of radioactive substance" over The Netherlands; West German scientists spoke of "an appreciable increase in radiation," and Paris' Municipal Hygiene Laboratory said that radioactivity over the city increased eight to nine times. From Tokyo came reports that rain which fell on the island of Kyushu contained 29,800 conts of radioactive particles per liter, compared with a norm of 20 to 30, and with...
...though, than to make the decisions required of a President. Stevenson does not give the impression of being particularly decisive. He might weigh his decisions so carefully as never to make any; our late foreign policy on China seemed to be conducted in this way. We "waited for the dust to settle" for so long that in the end we did nothing. Stevenson seems to have no clear idea of how far the American people will follow political leadership...
