...shortage of helicopters is easily detected and quickly cured. But the ultimate effects of McNamara's decisions to scrap projects such as the Air Force's Dyna-soar spacecraft and to phase out long-range heavy bombers, will not be fully measurable for years. McNamara has been spending $7 billion a year for research and development, far more than had been allocated previously; yet he is accused of killing more projects than he carries out. Ten years hence, the nuclear aircraft engine, which he abandoned, may prove to be a vital necessity...
...Blue. Not surprisingly, as Moskowitz's imaginary ship moved far beyond the solar system, the appearance of the sky began to change. As the ship approached them, the nearer stars began to shift their positions in familiar constellations, eventually disappearing from forward view as the spacecraft passed them. More distant stars remained in relatively fixed positions. In the view from the rear, the sun faded from sight as the craft flew beyond a distance of 30 light-years from the solar system, while 45 Eridani loomed ever larger ahead...
Surveyor program, which now has successfully soft-landed four out of the six spacecraft sent moonward. This remarkable average-as improbable as a pitcher tossing four no-hit games in six starts-is perhaps the greatest technological feat in the first decade of the space age. Russian space scientists have parachuted an instrument package onto Venus, but have yet to develop the approach radar and rocketry system that can set an unmanned spacecraft down on the airless moons as gently as a helicopter touches down on a landing strip...
...additional Surveyors, Hughes scientists believe that the reliable little craft would be ideal for further lunar exploring-even for a trip to Mars. Properly modified, they say, Surveyor could land gently on Mars and return pictures and data for only ¼ to ⅓ the cost of the planned Voyager spacecraft...
...ensuring that the craft would plunge into the earth's atmosphere at the 25,000-m.p.h. velocity that will be reached by a returning lunar mission. The maneuver was designed to test Apollo's heat shield against temperatures much higher than those encountered by Gemini and Mercury spacecraft, which re-entered the atmosphere from their orbital missions at about 17,000 m.p.h...
