...Discoverer XVII, launched from Vandenberg Air Force Base in California, swung into polar orbit, logged 1,000,000 miles in 31 turns around the earth, then, on signal popped its instrument capsule over the Pacific. As if that triumph of precision were not enough, an Air Force C-119 flying boxcar, one of nine planes covering a 12,500-sq.-mi. "ballpark" near Honolulu, snagged the parachuting capsule...
...clean Republican sweep of the Democratic South this autumn is as unlikely as polar bears on Peachtree Street. Nevertheless, the South is unusually restless politically. Nixon, in two trips to Dixie, has attracted more attention than Dwight Eisenhower did in the early stages of his campaigns. Poll after poll reports so many Southerners "undecided" that the Battle for the South could become the most fascinating and far-reaching of the year...
...went on to cite advances made in his own field of spectrophotometry and showed slides of the spectrum of light from Mars, which seem to indicate there is no oxygen on that planet. Mars' famed polar ice caps, he noted, are probably no more than frost "a few millimeters thick...
...system that watches the horizon with infra-red eyes and shoots high-pressure gas through a series of jets to keep the rocket horizontal in respect to the ground below. When a Discoverer - and there have been eleven fired so far - has circled the earth 17 times on a polar orbit, it passes over Kodiak, Alaska, where a radio control station sends an order that sets the guidance system on a new track, tilting it 60° from the horizontal. An electric impulse fires explosive bolts to kick off a re-entry capsule, a retrorocket slows the capsule...
...candy-striped medicine ball called Transit IB, forerunner of a series of U.S. Navy satellites that by 1962 will provide more exact navigational guidance for ships and planes (see SCIENCE). And even the long-jinxed Air Force Discoverer program got off a perfect launching of Discoverer XI into polar orbit, though airmen once again failed to recover the data capsule that the satellite ejected...
