NASA grounds space shuttle fleet after near-disaster in Discovery launch

Quote:

NASA is capable of technological marvels, as in the Deep Impact probe which deliberately struck the comet Tempel 1 on July 4, a feat that has been compared to hitting a bullet with another bullet (although actually much more difficult than that). But the space shuttle program is a technological nightmare, with electronics and engineering that were cutting-edge in the 1970s now preserved in an almost fossilized form in 2005. While the US military employs the most modern technologies for the deeply reactionary purposes of American imperialism—destroying human lives and the infrastructure of civilization—the resources devoted to manned space exploration are pathetically inadequate. There are 2.5 million parts in the shuttle, most of them based on specifications of 30 years ago, when the space shuttles were built. (Discovery is a relative youngster at 21 years old). Until the Columbia disaster, NASA still had some computers running with Intel 8086 microprocessors, the first ever used in PCs, which run about 300 times slower than today’s best computer chips. Wiring, bolts and other metal parts are replaced as they wear out, but some date back to the original construction. According to one press account, some electronic components contain transistors hand-soldered into circuit boards, a method of assembly that would be laughed out of any modern factory. According to another, NASA engineers “are sometimes reduced to hunting for obsolete hardware and electronics on eBay.”The new NASA administrator, Michael Griffin, made a revealing comparison, likening the space shuttle to a clipper ship—i.e., a once brilliant but now completely outmoded technology.
