...hydrogen-fueled SII second stage fired flawlessly, providing 1,000,000 Ibs. of thrust and boosting the rocket to an altitude of 115 miles before it, too, was jettisoned. Now it was the turn of the third-stage S-IVB. Firing its engine, it inserted itself, the attached Apollo spacecraft, its service module and the lunar module-a total of 140 tons-into orbit, with an apogee of 119 miles, a perigee of 114 miles. It was an impressive demonstration that, after ten years, the U.S. had finally overtaken and surpassed Russia in brute rocket power. The heaviest loads ever...
...landing last April, killing Soviet Cosmonaut Vladimir M. Komarov. Three days later, a cylindrical object called Cosmos 188 was rocketed aloft into the same orbital track, a scant 14.9 miles from Cosmos 186. The accuracy was remarkable, but it had to be. Western space experts have learned that Russian spacecraft radar lacks power for long-range precision, and what was to come depended largely on the radar equipment aboard...
...scientists say, computers aboard Cosmos 186, reportedly large enough to carry a crew of five, began the sophisticated automatic process of finding and linking up with Cosmos 188, the passive, beaconlike partner in the space pas de deux. Then, while 188 was still in its first orbit, the two spacecraft oriented their docking mechanisms toward one another. Painstakingly, 186 moved closer. Then, high over the Ascension Island area in the South Atlantic, 186 slipped its pronged nose into a docking collar mounted on 188, linking the electrical circuits of the two vehicles. For 31 hours, the two spacecraft formed...
...data transmitted back to earth from Russia's Venus 4 and the U.S.'s Mariner 5 spacecraft, scientists last week pieced together a picture of Venus as a place of unbearable heat, a dense and noxious atmosphere, and nightmarish optical effects...
Mariner 5's findings, released last week, agree generally with data sent back by Russia's Venus 4 and its landing capsule. Neither spacecraft found evidence of Van Allen-like radiation belts around Venus, both reported hydrogen coronas and found that carbon dioxide was the principal constituent of the Venusian atmosphere. Mariner's finding that the atmosphere was "at least" 7 to 8 times as dense as the earth's does not contradict more precise Russian data showing densities 15 to 22 times as great...
