...cross picket lines set up by the strikers. The railroad has a contract with the National Aeronautics and Space Administration to haul heavy building materials to the cape. As a result of the picketing, 30 projects worth $200 million were closed down, including construction of the site where the Saturn rocket moon shot will be assembled...
Trailing a muffled bellow from its eight engines, Saturn seemed to rise with unnatural slowness. During the first ten seconds it climbed less than twice its own length, then it quickly gathered speed and rumbled behind a low-flying cloud. At 48 miles' altitude, the massive first-stage booster shut off and separated. The hydrogen-burning second stage took over, and it burned perfectly for eight minutes. When it was 1,300 miles downrange and 375 miles north of Antigua Island, the triumphant announcement came: Saturn had reached orbiting speed. The new satellite weighs...
Crewless Liner. The success of the Saturn SA-5, which puts the U.S. far ahead of the Russians, is more than mere astronautical muscle-flexing. It was achieved by almost incredible complexity and sophistication. The first-stage booster, built by Chrysler, gets its 1,500,000 Ibs, of thrust from eight H-l engines originally developed by North American for the Atlas and other mis siles. Their tangle of auxiliary plumbing is like a jam session of snakes, and it gives most engineers the shudders...
...their kerosene and liquid oxygen fuel through flexible tubing, from nine tanks interconnected so that if one engine fails, the others will use its share of fuel and burn longer. Backing up the engines is an incredible array of pumps, valves, gas generators, high-pressure tanks and cables. Saturn SA-5 is as complicated as a crewless ocean liner operated by flash-quick automatons...
...Saturn's second stage, built by Douglas Aircraft Co., is even more sophisticated because of its uncomfortable fuel, liquid hydrogen. Space engineers admire LH2 because it provides better than one-third more thrust than kerosene, but it is hell to handle. It is so light (7% the weight of water) that it requires enormous tanks, elaborately insulated to keep the hydrogen from flashing to vapor. A long list of new materials had to be developed that would not lose their strength at the chilling touch...
