Earlier this month NASA announced they are going to jettison trash into space that will likely strike the Earth sometime within the next 300 days. Next it is revealed that operating spacecraft while intoxicated has been ignored more than once by the higher-ups at NASA, and finally it’s insinuated that NASA’s longstanding culture of disregarding unpleasant facts was likely partially responsible for the deaths of the Columbia crew. What’s going on?
One of the most popular features of Google has been their mapping programs. Their continued efforts to acquire the best satellite imagery of everywhere has let the average computer user to zoom in on archaeological and geographical sites that, prior to its inception, had been reserved for scientists with satellite imagery at their finger tips.
