http://www.washingtonpost.com/sf/national/2014/12/15/nasas-349-million-monument-to-its-drift/ In June, NASA finished work on a huge construction project here in Mississippi: a $349 million laboratory tower, designed to test a new rocket engine in a chamber that mimicked the vacuum of space. Then, NASA did something odd. As soon as the work was done, it shut the tower down. The project was officially “mothballed” — closed up and left empty — without ever being used. The result was that NASA spent four more years building something it didn’t need. Now, the agency will spend about $700,000 a year to maintain it in disuse.
