...Center in Greenbelt, Md., were able to pinpoint Uemura's positions by monitoring signals from a 3½-lb. transmitter mounted on his sledge. The transmissions were picked up by a Nimbus 6 meteorological satellite as it passed over the Pole every 108 minutes and relayed by a NASA tracking station in Fairbanks, Alaska, to Greenbelt...
...experiments will also provide a good test of Building 550, which was designed to prevent material from recombinant DNA work from escaping into the environment. NIH officials are confident that the new lab is even more secure than the Lunar Receiving Laboratory, which was built by NASA at a time when it was still thought that astronauts might bring back dangerous bugs from the moon...
...fibers escape into the air-either during their manufacture or when the composite material is purposely or accidentally incinerated-they can settle on electrical equipment with disastrous results: carbon fibers are good conductors of electricity and thus can cause short circuits, arcing and sometimes fire. According to a recent NASA study, there have been more than a dozen such incidents since 1970 in industrial plants producing or using the fibers. As use of the composites increases, careless disposal and burning of wastes could release enough fibers into the air to short out air conditioners, TV sets, radios and even large...
...that a cloud of carbon fibers could be used, for instance, to incapacitate electrical equipment over wide areas-as well as knock out enemy radar. Because some 350 tons of carbon fibers are now produced annually in the U.S. and abroad, the Carter Administration ordered that much of the NASA study be made public. It also directed several agencies under the auspices of the Department of Commerce to look into the matter further...
