Vanguard II was the first big success for the National Aeronautics and Space Administration. Encouraged and confident, NASA outlined to Congress its ambitious program for peaceful space navigation. Some of its projects: ¶ An Atlas with a single upper stage to put a 3,000-lb. satellite in orbit (available soon...
...Vega and Centaur, both based on Atlas, but with two additional stages. Vega has a section of the Vanguard for its second stage. Centaur's second stage will burn hydrogen, whose high energy, according to NASA's Dr. Abe Silverstein, "will greatly increase our capability to send a mission to Mars and Venus." ¶ Most advanced project in the works: a five-stage job with a 6,000,000-lb. thrust first stage, which will be capable of carrying a man to the moon and bringing him back. In combination with a nuclear-powered upper-stage rocket...
...cost of this program, said NASA Director Glennan, will be $485.3 million, and he warned Congress that future bills would be higher. "The cost of our space programs," he said, "will increase year by year. We expect that satellites will be widely used in meteorology-witness the Vanguard II cloud cover experiment-and in worldwide communications. The value of such advances will be counted in the billions of dollars...
...test-pilot training, a minimum of 1,500 logged hours of flight time, age less than 40, maximum height 5 ft. 11 in., superb physical condition, and physical and psychological attributes suited for space flight. Last week Keith Glennan, boss of the National Aeronautics and Space Administration, announced that NASA had found no to fill the bill, that from their ranks would be chosen the first American to be shot into orbit...
Once the gravitational variations had been measured, the NASA scientists could calculate their effect on the shape of the earth. The excess of gravitation around the North Pole, for instance, indicates an extra 200-ft. bulge of rock over an area equivalent to the Atlantic Ocean. This extra mass would attract enough sea water to raise sea level about 50 ft. above the theoretical curve of an ideally plastic earth. None of the newfound bulges are large compared to the polar spin-flattening (about 13 miles), but they may cast new light on the earth's mysterious interior...
