...belt, Scientist Van Allen told the American Physical Society at Chicago, seems to be a great doughnut made chiefly of fast-moving electrons and protons circulating around the earth on both sides of its magnetic equator (see diagram). Only the lower parts have been observed with any accuracy. The upper limits are deduced from knowledge of the magnetic field. The Air Force's Pioneer, soaring far past the 1,400-mile level reached by the Explorers, confirmed "tentatively and partially" that the lethal radiation drops off sharply around 7,000 miles...
Since the air is too thin 100 miles up for any aerodynamic controls to be effective, the X-15 has an independent system of ballistic controls that need no air. In the nose are four pairs of small jets pointing up, down, left and right (see diagram). When the pilot wants to depress the nose of his craft in near-airless space, he will shoot superheated steam (produced by catalyzed hydrogen peroxide) through the upward-pointing jets. The reaction will push the nose downward. Similar jets in the wingtips will keep the wings level or make the ship bank...
...when all long-range missiles will lurk beneath the earth, invisible and well-nigh invulnerable to enemy attack. The sunken silo at Vandenberg is only one part of a subterranean complex under construction as Titan's first "hard base." Adjoining the missile tank are other sunken cylinders (see diagram), housing air-conditioning and hydraulic equipment, a power station, liquid oxygen and fuel tanks, and a command control center for the launch crew. Tunnels connect the widely dispersed elements, but after the alert, only the control center will be occupied. Remotely controlled, the monster, fueled and armed, will rise majestically...
Kent's heart stopped soon after the heart sac was cut open, but promptly picked up its beat again on being massaged. Dr. Glenn cut through the right pulmonary artery (see diagram) at its beginning near the ventricle, carried the free end around to a hole, half an inch across, cut in the side of the superior vena cava, and stitched it in, like a plumber's elbow joint. Then he tied off the vein near its normal entrance to the auricle. In this way, 30% to 40% of Kent's venous blood (the proportion carried...
...rocket engine depends largely on its exhaust velocity, the nuclear engine has a big initial advantage, but it has to pay a high price. The engine itself, which must be cooled elaborately by the liquid hydrogen, will be about as complicated as a conventional chemical engine (see diagram). Its controls will be even more complicated, and all its delicate parts will have to perform perfectly in spite of intense gamma rays striking through them at takeoff...
