Like the moon, Mercury apparently has no appreciable atmosphere or magnetic field. Its surface, bombarded by intense solar radiation, may be quite dusty. Recently, radar astronomers suggested that Mercury has mountains as high as 4,000 ft., rolling hills and valleys, and some lunar-like craters, some of them perhaps of volcanic origin. Surface temperatures are far more extreme than those on either the moon or Mars. At the height of the Mercurian day, they may reach 940° F., more than enough to melt lead. At night they plunge to - 350° F. No living things could be expected...
...slope sharply down into the bowels of this deep crater, where shiny steel skyscrapers beckon mystically in the clear sunny air. Spread out below and beyond, extending almost to the snow-capped Andean peaks in the distance, sparkles La Paz, a booming city seemingly dropped from space into a lunar landscape...
Consisting largely of gray matter and fissured like a lunar landscape, the cerebrum dominates the human brain, filling the dome of the skull. It also makes man what he is, for it contains the areas that control thought and consciousness, the quality that enables man to remember his past, understand the present and anticipate his future...
...verb rather than the season) occur twice a month: when the moon is full and when it is new. Spring tides themselves may be driven to further extremes when the elliptical path of the moon brings it closest to the earth's surface, increasing the effect of lunar gravity...
Died. Gerard Peter Kuiper, 68, astronomer and director of the unmanned Ranger lunar photographic missions that helped pinpoint landing sites for the Apollo moon shots; of a heart attack; in Mexico City. As a director of the University of Chicago's Yerkes Observatory, he made a number of important discoveries, including satellites of both Uranus (1948) and Neptune (1949). When, in the early 1960s, other scientists were concerned that a spacecraft landing on the moon would sink in an ocean of dust, Kuiper correctly described the lunar surface as resembling "crunchy snow...
