...week's end the infra-red spectrometer on board Mariner 7, the second of the two vehicles that flew past Mars, detected two gases-ammonia and methane-that could indicate the presence of primitive life. Both are produced on earth by biological decay. George C. Pimentel, a University of California chemist, said that he was unable to determine the amount of ammonia in the Martian atmosphere, but he estimated the concentration of methane as "no more than a few parts per million." In the earth's atmosphere, the amount is about 1.5 p.p.m.-and added rather jovially that...
Seeking to answer that age-old puzzle, scientists from Caltech's Jet Propulsion Laboratory at Pasadena crammed Mariners 6 and 7 with vastly improved electronic gear, ranging from tape recorders to miniature computers to extraordinarily sensitive infra-red and ultraviolet measuring equipment. The total cost of the Mariners and their launch vehicles: $148 million...
Though Mariner 6 needed only one mid-course correction throughout its long journey, and Mariner 7 was almost on target, the flights were not completely trouble-free. Last week one of Mariner 6's infra-red spectrometers balked just as it was supposed to search out the gases and vapors in the Martian atmosphere. JPL technicians explained that the spectrometer, which should be cooled to below - 400° F. to operate efficiently, refused to chill at all. Mariner 7 caused even greater concern at Mission Control when it went off the air entirely for seven hours. Apparently struck...
...view Moholy within the limits of his paintings and constructions is to see but one aspect of an immensely versatile personality. Some of his more visionary notions were industrial designs-an engine fueled by sunlight, a motorless dishwasher, an infra-red oven that would cook dinner at the table. The creation of beautiful objects per se was never his intent. "I don't like the word beauty," he often declared. "Utility and emotion and satisfaction, those are more important words." At one point, he even foresaw a day when paint and brushes would be discarded, though he conceded that...
...Angels in California? No, Viet Nam, where the U.S. military, never tiring in its search for methods to find an elusive enemy, has just added the motorcycle to the hunter's inventory that has, at one time or other, included such exotica as people-sniffing bedbugs, infra-red photography and side-looking radar...
