...reason that Pioneer lacked those few more miles of speed is still being debated by the rocket experts. The official explanation, that its first stage climbed too steeply and so did not benefit fully from the speed of the earth's rotation, is not accepted by all. Another possibility is that some of the liquid fuel in the second-stage tanks failed to burn. A third theory is that the solid fuel in the third-stage rocket became chilled before firing and therefore did not give the expected amount of energy...
...Pioneer faltered and began to fall back, scientists at tracking stations tried to fire the Stage Four rocket in the hope it would send the probe into an orbit around the earth. The rocket did not fire. The official theory is that the interior temperature of the Pioneer fell so low (35°F.) that its battery lost power and could not work the firing system. Some experts have suggested a simpler cause: a broken electrical connection...
With its soft. length and 22-ft. wingspan, the X-15 looks more like a missile than an airplane. A sophisticated descendant of the X-1 rocket plane in which Test Pilot "Chuck" Yeager first broke the sound barrier (TIME, June 21, 1948), it is expected to reach 3,600 m.p.h.-twice the speed of a high-powered rifle bullet. Since such speeds cannot be maintained in the lower atmosphere, the X-15 will be carried to 35,000 ft. by a B-52, will then climb to an altitude of 100 miles. Burning liquid ammonia and liquid oxygen...
