First time accepted submitter Martin S. writes "How NASA Engineers have reverse engineered the F1 engine of a Saturn V launcher, because: 'every scrap of documentation produced during Project Apollo, including the design documents for the Saturn V and the F-1 engines, remains on file. If re-creating the F-1 engine were simply a matter of cribbing from some 1960s blueprints, NASA would have already done so.
A typical design document for something like the F-1, though, was produced under intense deadline pressure and lacked even the barest forms of computerized design aids. Such a document simply cannot tell the entire story of the hardware. Each F-1 engine was uniquely built by hand, and each has its own undocumented quirks. In addition, the design process used in the 1960s was necessarily iterative: engineers would design a component, fabricate it, test it, and see how it performed. Then they would modify the design, build the new version, and test it again. This would continue until the design was "good enough."'

The NSA says the Utah Data Center is a facility for the intelligence community that will have a major focus on cyber security. Some published reports suggest it could hold 5 zettabytes of data. Asked if the Utah Data Center would hold the data of American citizens, Alexander [director of the NSA] said, 'No...we don't hold data on U.S. citizens,' adding that the NSA staff 'take protecting your civil liberties and privacy as the most important thing that they do, and securing this nation.' But critics, including former NSA employees, say the data center is front and center in the debate over liberty, security and privacy."
According to University of Utah computing professor Matthew Might, one thing is clear about the Utah Data Center, it means good paying jobs
. "The federal government is giving money to the U.'s programming department to develop jobs to fill the NSA building," he says.Read Replies (0)
