Psychological Problems. During debriefing sessions last week, Gordon confirmed what the movies make obvious. In his weightless state, he complained, he had difficulty holding his equipment and keeping it in front of him. He found that his legs moved uncontrollably, that every motion required the utmost physical effort. Space experts were convinced that part of Gordon's problems with EVA were psychological. "No matter how many times you've seen EVA films and been told that you'll not fall," said one Air Force officer assigned to the Gemini missions, "the first time...
Gordon's troubles, similar to those encountered by Astronaut Eugene Cernan on the flight of Gemini 9, were proof to NASA officials that the mere effort of controlling arm and leg movements during a weightless space walk in a bulky space suit is far more trying than anyone had imagined. As a result, future space flights will probably schedule less ambitious space-walking chores...
...spaceship toward the moon. The trouble is, its virtues are not bought cheaply. Its extreme volatility and the - 423° F. temperature necessary to keep it in liquid form make it difficult to deal with both on the ground and in space. NASA spacemen had theorized that once weightless in orbit, liquid hydrogen would scatter around its fuel tank in an uneven mixture of liquid and gas. And unless liquid hydrogen can be kept at the bottom of the tank, it cannot reach the valves through which it is pumped to the combustion chamber...
...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...
...went to her bag, took out the small bottle and stared at the tiny, bullet-shaped red capsules. Seconals. Should she try one? She felt her heart pound, but she swallowed it and rushed into bed. Then she felt it! Oh, God! It was glorious! Her whole body felt weightless. Her head was heavy, yet light as air. She was going to sleep . . . sleep . . . oh, the beautiful little red doll...
