...program began in 1955, when President Eisenhower directed the Navy to adapt the Army's liquid-fuel Jupiter missile for use on surface ships. This proved impractical, but the Navy within a year had made dramatic progress toward development of its own solid-fuel Polaris missile, and had also overcome many of the technical problems of designing a nuclear-powered submarine. The two programs logically became one. Working side by side, Admirals William F. Raborn (more recently head of the CIA) and Hyman Rickover headed a team that devised a complex navigational device that could plot...
...fighter-bombers last week continued to hammer at Hanoi's roads, bridges and fuel depots. As in the week before, Hanoi responded with the most sophisticated weaponry in its defensive armory-and again found it useless. Twenty SAM ground-to-air missiles were fired. All missed. Supersonic MIG-21 fighters rose to tangle with U.S. Air Force F-4C Phantoms flying bomber escort north of Hanoi. North Viet Nam is thought to have only 15 of the advanced Russian jets, and the encounter cost them two of those, knocked down by the Phantoms' Sidewinder missiles-the second...
...question remained: would the theory prove practical in space? To find out, NASA engineers installed television cameras inside the SIV B's hydrogen fuel tank. All through the acceleration of blastoff, and while the Saturn I first stage was pushing the SIV B aloft, the TV screens at the Houston control center showed the liquid hydrogen settled and calm on the bottom of the tank, its surface barely rippling. After the first stage had dropped away and the SIV B's engine was fired to insert it into orbit, the level of the liquid hydrogen could be seen...
...Sloshing. Then, with the SIV B in orbit and its engine shut down, the TV screens showed a weird transformation in the fuel tank. Now weightless, globules of liquid hydrogen ripped loose from the churning surface and began to drift upward. Ground controllers immediately radioed signals that opened the SIV B's tank vents, allowing escaping gases to accelerate the vehicle slightly. On the screen, the globs could be seen obediently settling back to the surface. "It looks calm," the controllers reported. "It's behaving itself. There's no sloshing...
With its tank vents still spewing tiny jets of gas, the slowly accelerating SIV B was then put through a simulated engine restart. Valves at the bottom of the tank opened, allowing liquid hydrogen to flow into the combustion chamber. Clearly visible on TV, the dwindling fuel hugged the bottom of the tank, its surface calm...
