...Force's defunct Navaho missile program-kept Nautilus on course and on depth, gave its captain instant readings of position. Ten sound-detection devices measured the distance to the ice above and the thickness of the ice while three other devices sounded the sea bed. Findings: polar ice is generally about 12 ft. thick, although some ridges bulged down 50 ft. or more. Crew comforts were also measuring up: the sub's crew was treated to more than 30 movies, e.g., Katharine Hepburn in Desk Set, and cribbage, chess and acey-deucey tournaments were under...
...engine, says Rocketdyne, would open new possibilities. Combined with appropriate secondary stages, it could put a 20,000-lb. satellite in a polar orbit 1,000 miles high. It could carry 6,200 Ibs. of payload around the moon, 2,000 Ibs. around Mars. With proper auxiliary apparatus it could land a 1,600-lb. payload gently on the moon, or a 400-lb. payload on Mars. Yoked together, four of these engines should be capable of putting man into space along with enough of his natural environment to keep him alive...
Billows & Pillows. In his portrait, Author Warner tells a great many of the old Nelson stories, and some unfamiliar ones. Example: as a midshipman at 14, Nelson found himself on an expedition to the Arctic. He tried to kill a polar bear to get its skin for his father. He missed the beast with his first shot and wanted to clobber it with a clubbed musket...
...Bermuda high, a swirling mass of moist tropical air off the Atlantic Coast that acts as a protective buffer to icy arctic blasts. This winter, because of abnormal patterns in the high altitude winds (TIME, Jan. 20), the Bermuda high has been flubbing its job. Result: successive masses of polar air have flowed down the Mississippi Valley and eastward, spreading out to reach deep into Florida, to bring abnormal cold and, in the clash with tropical air masses, heavy rains and snows...
...planet is still in the grip of an Ice Age, with icecaps at both polar regions, and the IGY wants to know whether it is coming or going. In Greenland, scientists have bored 1,438 ft. into the ice. In Antarctica they are doing the same, and measuring the great icecap by seismic waves. Other scientists are observing the advance or retreat of smaller glaciers in Temperate Zone mountains. Their reports may tell what changes of climate lie in the earth's future...
