...first Explorer space satellites. The Air Force sent a lunar-probe rocket 80,000 miles toward the moon, at year's end fired one Atlas intercontinental missile 4,000 miles, another the full distance of 6,300 miles, still another into orbit, brought the Thor IRBM into the training stage and the hands of combat troops. The Navy sent the nuclear submarine Nautilus under the North Pole, made huge psychological warfare headlines, opened up a new strategic frontier...
...clear, calm night at Cape Canaveral. The Army, making its first attempt to shoot the moon, had spent weeks fussing over the Juno II, a 60-ton Jupiter IRBM with a spike of high-speed rockets mounted on its nose. At twelve seconds after 12:45 a.m., almost exactly on schedule, Juno II took off. It climbed loudly but smoothly, arching slightly north of east. For about three minutes the first-stage rocket burned brightly, diminishing slowly with distance. Then its power shut off, and the upper stages coasted flameless for 55 seconds. About 110 miles up and 160 miles...
...first shot, scheduled for next month, will use a Thor IRBM as its first stage and is expected to put 1,300 lbs. in orbit. The instrument payload, said Johnson, will weigh "several hundred pounds." Later shots will use Atlas ICBMs as boosters and will put as much as five tons in orbit. Some of the satellites will carry live animals, including a "primate," and attempts will be made to bring them back alive...
Downgrading the IRBM. With NATO allies except Britain and Italy showing scant enthusiasm for U.S.-offered intermediate-range missiles, the Pentagon is reappraising the worth of the IRBM, designed for launching from overseas sites, as against the intercontinental missile, designed for launching from U.S. bases. Trend: more reliance on ICBMs, less on IRBMs, which would be of little use in a limited war and would be vulnerable to Russian attacks on overseas bases...
