Power Problem. The AEC did not say how feasible nuclear rockets look. Most scientific judgments about them have been pessimistic. Rocket motors develop their thrust by burning fuel with an oxidizer and expelling the products of combustion at high speed through a tail pipe. The energy of combustion is necessary to make the gases move fast, but the mass (weight) of the gases is also necessary. No mass, no thrust...
...tons of coal. A modest amount of U-235 could, so far as energy is concerned, propel a commodious space cruiser to the moon and back. But energy is not enough. A uranium-burning rocket motor would have no products of combustion to shoot out of its tail pipe, and without some massive material to jettison, the motor would have no thrust...
...ways of using nuclear fuel in rockets have been dreamed up by the imaginative engineers who plan for space travel. One of their proposals is a nuclear reactor running a conventional electrical generator. The current from it ionizes atoms of some convenient element and expels them from the tail pipe. An "ionic motor" of this sort can run, theoretically, almost forever on a cupful of uranium...
...Deep Oil. The Magnolia Petroleum Co. announced a drilling mud that will make it possible to reach oil at depths that could neyer be attempted before, save more than $50,000 in costs on deep wells. Chemical muds are pumped down inside a drill pipe to the bit and then back up the hole, thus holding down subterranean oil pressures, keeping the bit cool, and carrying the drill cuttings back up to the surface. In deep holes, conventional muds jell under the intense heat and dry up at 300° F, cause expensive delays. The new muds, DMS (Drilling...
Asked if he considered it possible that he would ever again play a role in American politics. Earl Browder, 65. head of the Communist Party. U.S.A.. during its 14 most powerful years (1931-45), drew thoughtfully on his pipe and replied: "Realistically, there are no grounds on which anyone could base such a prediction...
