...specialized military requirements demand specialized space technology. The civilian officials and scientists of the National Aeronautics and Space Administration are shooting for the moon, and they tend to shrug off the military aspects of space. In contrast to the moonshooters, the Air Force foresees the need for a manned spacecraft, rugged and simple in design, that will be ready to go any time in any weather, reach orbit, maneuver in space, and return to earth as a matter of combat routine...
...answer came Sunday morning, 23 hours and 32 minutes after Nikolayev's launching, with the news that Vostok IV was in orbit. The Soviet announcement said that the purpose of the mission was to check "contact" between spacecraft in similar orbits and to gain new knowledge on the effects of sustained weightlessness on the human body. Moscow declared that both cosmonauts were quickly in radio communication as they soared around the globe approximately every 88 minutes, were even able to exchange grins by means of direct television contact. Moreover, the cosmonauts reported to the ground that they could...
...intervals, Nikolayev and Popovich reported that they unstrapped themselves from their harnesses and shifted weightlessly in their cabins, stretching their muscles as much as .their bulky orange space suits would allow. Through the portholes of their spacecraft, they photographed the moon and other celestial bodies. "The moon looked not flat, as from the earth, but like a ball hanging in empty space," said Nikolayev later. In their logbooks, they noted the temperature, pressure and humidity of their vehicles, as well as their own pulse and blood pressure. Soviet scientists on the ground received electrocardiograms direct from sensors attached...
Weighing about 85,000 Ibs., the moon bound spacecraft will have three parts: the command module, housing the three-man crew; the service module, with supplies, engines and propellants; and the small landing bug. During the three-day voyage to the moon, the astronauts will make computations and burn fuel to correct their course. They will also take the bug out of the rear of the service module and attach it to the nose of the command module. After arriving in the vicinity of the moon, they will burn a little more fuel to nudge their ship into...
...voyage will be safe or easy. All sorts of unexpected obstacles may force changes of plan. No one knows, for instance, whether human bodies can stand a full week exposed to zero gravity. If they cannot, some sort of substitute gravity will have to be supplied by spinning the spacecraft−a stunt that will call for radically new apparatus. Another unknown is the lunar surface; no one is sure at present just how hostile it is. Astronomers point out that it is inconceivably old, that it has stewed in a vacuum and been exposed to fierce radiation for billions...
