Though the thrust supplied by the new fuel is lower than the performance of conventional liquid propellants, it has some distinct advantages. It does away with the necessity of disposing of its major ingredient in space, and scientists calculate that because a MONEX W rocket will manufacture part of its fuel in flight, it will actually have less lift-off weight than a conventionally fueled rocket designed for the same long-range mission...
Grim Days Ahead. Florentines attacked the government for delays in relief. "How is it possible to move this mass of liquid and mud with shovels?" complained Mayor Piero Bargellini. "We need earth movers, bulldozers, trucks." In the Italian Parliament, Premier Aldo Moro was jeered-mostly trom the Communist benches-when he rose to speak. The government appropriated $320 million for emergency aid, raising the gasoline tax 6.4? per gallon...
...propelled vehicles, like the Snark and the Navaho, that American aerospace companies were working on before the ballistic missiles like Minuteman and Titan were developed in the late 1950s. Some Western sources think the Chinese used a copy of the Russian SS-4 missile, a true rocket propelled by liquid fuel and capable of carrying a miniaturized nuclear warhead 1,000 miles. If the Chinese mounted an outsized atomic "device" on the SS-4 copy, it could well have cut the rocket's range to 500 miles...
...discovery of methanelike compounds on Mars, Kaplan believes, leaves only one important obstacle to life on the red planet: the apparent lack of water in liquid form. What little Martian water there is exists as polar-cap frost or vapor in the atmosphere; there are no oceans or even lakes similar to those in which the first terrestrial life evolved. "It would be a strenuous climate for life," says Kaplan, "but then not all life-even on earth-requires liquid water...
Simulated Solar Wind. To test his theory, Sun borrowed samples of meteorites believed to be similar to those on the moon. Using liquid nitrogen, he cooled them to-320°F. and bombarded them with high-energy electrons that simulated the impact of solar-wind protons for a 14-day period. No glow was produced. When Sun removed the liquid nitrogen and rapidly heated the samples, however, they began to give off vivid and pulsating light. The Westinghouse physicist is now working on further laboratory tests to support his theory. He believes that it can also be confirmed by careful...
