...module's two spherical oxygen tanks was completely empty; nearly 320 Ibs. of supercold ( -297° F.) oxygen, a highly pressured mix of gas and liquid, had gushed out of the spacecraft, apparently through a rupture in its thin alloy skin. Looking out of his window, Lovell could see vapor streaming by. "We are venting something into space," he reported. "It's a gas of some sort." At the same time, the spacecraft began to pitch and roll in reaction to the violent expulsion...
...allot $600 to help the state root out a blight called pine blister rust went down because, as one man said: "We can do it better, and for nothing." One item on the "warrant," or agenda, suggested replacing Mount Vernon's 22 conventional street lights with 17 mercury-vapor lights to provide better illumination. When the first selectman explained that the change would increase the monthly electric bill by $25.90, a resident shouted: "Forget it!" It was unanimously voted down...
Golden Tube. The target of the chromatographic detective work performed by the bomb sniffer is the vapor from a chemical called ethylene glycol dinitrate (EGDN), one of the principal components of emissions given off by dynamite. With the aid of a small internal fan, the detector samples air in the vicinity of a suspect object and passes the vapors over a modern equivalent of Tsvett's limestone-a rough gold-plated copper surface that has a special affinity for EGDN. As the molecules adhere to it, their concentration increases. The special surface is then heated...
...quantity on Mars? Quite probably, say Plummer and Carson. The thin Martian atmosphere consists largely of carbon dioxide; it also contains a trace of carbon monoxide, which may be vented from Martian volcanoes. Under intense ultraviolet radiation from the sun, the two gases could combine into carbon-suboxide vapor. Indeed, the two scientists were able to simulate that very reaction in the laboratory. Their experiment also demonstrated that when the temperature is high enough, the vapor could solidify into a fine granular material, turn yellow and precipitate onto the Martian surface. Where would such a "snowfall" occur? Most likely...
