Chief complication is keeping the gyro platform absolutely stable and unaffected by gravity; it tends to drift. Such forces as bearing friction and the rotation of the earth itself tend to tilt the platform out of line. On the Nautilus the system apparently worked without significant drift for the full 96 hours under the ice, and eventually the Navy hopes for accuracy up to 90 days at a time...
...body of a long-range missile lives only for its nose. Once shot into space, the nose, with its payload of thermonuclear explosive, speeds on alone, and its problem becomes re-entry into the atmosphere. U.S. missilemen need nose cones that will not burn up from friction as they plummet earthward in a long arc at up to 16,000 m.p.h...
...only a small segment of the economic spectrum is represented. There are hardly any Negro students (less than a half-dozen per class) in the group, although there is a high proportion of Jewish and Catholic pupils; but in a tolerant and religiously easy-going village like Scarsdale, religious friction within the school is negligible. Politically too, the range of allegiances is fairly middle-of-the roadish...
When the nose cone hit the atmosphere after its arch through space, its tip got so hot that it glowed like a star. It was, in effect, a man-made meteor that gradually lost speed by air friction. When its speed was low enough (figure secret) to eliminate further heating, a lot of things started happening fast...
...powerful than the earth's) from the rocket's acceleration piles tip a crushing impact on the spaceman, whose normal weight -say 150 Ibs. -multiplies to three-quarters of a ton. On the outer skin of his capsule, hurtling away from earth at 25,000 m.p.h., the friction of the atmosphere generates temperatures tip to 1,600°F. Beyond the atmosphere, the outside temperature drops to -454°F. -close to absolute zero -and gone is the atmospheric pressure that keeps man's organs from exploding like a blood bomb...
