...presence of oxygen was detected by the pyrolytic release experiment which was designed to test for the occurence of photosynthesis by exposing a soil sample to radiation from a xenon lamp. The oxygen was produced before the lamp was switched...
...housed in 1-ft. cubes and weigh only 30 lbs. apiece. Each is crammed with 140,000 electronic components-including 122,000 transistors-40 thermostats, three tiny ovens, bottled radioactive gases, one pocket-sized chromatograph (used to identify the chemical component of the substance under study) and a small xenon lamp that can simulate sunshine. Costing $16.9 million each, the labs can perform three different life-detection experiments without any human help...
...these chemicals. In another test, soil will be exposed to a nutrient containing radioactive carbon 14. If any microorganisms consume the nutrient and give off carbon-bearing gases as metabolic wastes, those wastes will be radioactively "tagged" and readily identified. Lastly, a Martian soil sample will be exposed to xenon "sunlight" and a simulated Martian atmosphere of radioactive carbon dioxide and water traces. After five days, the atmosphere will be purged, and the sample will be baked to more than 1000° F. If vapors given off include any carbon 14, the scientists will be able to conclude that...
Amid the crack of 450-volt xenon strobes, the silent zap of lasers and an unprecedented clicking of turnstiles, the Los Angeles County Museum's exhibition called "Art and Technology" is under way at last. It will run through August, and it affords a revealing spectacle of the stimuli and problems that rise out of a major encounter of art and industry...
